Five Layers of Quality. Delphi Brake Pads. Page 2DDSX552(EN)
5 Layers of Quality. Delphi Brake Pads.
Brake pads are one of the most important components in the braking system. Responsible for stopping vehicles quicker and quieter than ever before, they are
subjected to incredible stress, day in, day out. In fact, the pressure created within the
system can build up to 2000 psi, and temperatures can reach as high as 700ºC. This
is why you mustn’t compromise when choosing which brake pads to fit...so don’t!
As a leading manufacturer of OE safety technology, Delphi brake pads are designed,
manufactured and tested to the meet the same standards of performance, consistency
and longevity as the OE. We call it Delphi’s “5 Layers of Quality”.
So when you think braking quality, remember the five reasons why. Remember Delphi.
1: Shims.
One of the secrets to quiet
brakes is noise-dampening
shims. However, many
aftermarket companies do
not fit these as standard.
Our OE-quality shims are
multi-layered with differing
grades of dampening
materials. These layers are
finely tuned to bring out
the very best qualities – the
material is carefully selected
and either mechanically
attached, clipped and/or
hot bonded for improved
noise dampening.
2: Back Plate.
The back plate provides a base
for all other components, so it
goes without saying that it must
be strong and resistant. All Delphi
back plates are manufactured
from high-strength pressed steel
to the same shape and design as
the OE. A special powder coating,
highly resistant to extreme
temperatures and chemicals/
oils, helps to ensure optimum
protection against corrosion.
It also helps to maintain precise
dimensions and tolerances, for
easier pad installation and uniform
transmission of pressure from the
brake system to the pads.
3: OE Underlayer
Technology.
Unlike other aftermarket
manufacturers, every Delphi pad
incorporates a special underlayer.
Sandwiched between the back
plate and friction material, the 3mm
layer of noise-absorbing friction
material acts as a thermal insulator,
lowering the caliper’s operating
temperature. This is critical during
prolonged or heavy braking, as it
helps to reduce heat transfer to the
brake fluid, preventing it from boiling
and helping to maintain effective
braking. The underlayer also helps to
increase the adhesion between the
back plate and friction material for a
much stronger pad.
4: Friction Material.
Brakes on high performance vehicles
work very differently to those on
small, “about town” cars, so it stands
to reason that the pad’s friction
material should be tailored to the
vehicle. We use over 130 different
friction ingredients to create 20 unique
formulations for the very best match.
Other aftermarket manufacturers
use only one or two, resulting in an
inevitable compromise in performance.
But we don’t rest on our laurels. We’re
constantly testing new formulations
– more than 300, every year. This
continual development helps us always
stay ahead of the curve when it comes
to both vehicle performance and
the environment.
5: Friction Surface.
Delphi pads feature OE
configured chamfers, where
required, to help shorten
bedding in, and reduce noise
during this period. Whatever
their angle, shape, or position,
they’re designed to perfectly
compliment the friction
material and pad shape, for
OE performance from day
one. Our brake pads also
include slots, again, where
required. Just like the OE,
they allow the pad to flex
without cracking the friction
material, and help to remove
water and dust from between
the pads and discs.
For five layers of quality, you and your
customers can trust, choose Delphi.

Delphi MAF Sensors. Bringing OE Technology and Expertise to the Aftermarket.
The Delphi difference.
Proprietary temperature
compensation design for
outstanding performance
over a wide range of
ambient temperatures.
Fast response to changing
engine conditions - typically less
than 15 milliseconds to respond
to 90 percent of a flow change.
Tested on state-of-the-art
sonic nozzle-testing equipment
capturing over 6,000 data
points per flow, for optimal
calibration accuracy.
Flow tested to match
the OE including:
› Signal stability (noise).
› Temperature compensation
(ability of the MAF sensor to
measure air flow accurately
from -30°C to 70°C).
› Electromagnetic compatibility.
Innovative, dual-heated elements
on specific references for optimal
performance, fuel efficiency and
reduced emissions.
Built with all-new components, never
remanufactured – remanufactured
MAFs are simply cleaned and tested,
so any contamination on the sensor
may not be eliminated, resulting in
inaccurate readings to the ECU.
Two service options available: as a
complete unit including the flow tube
and probe, or as a probe-only design.
Advanced DS diagnostics with the
ability to read live data from the MAF,
and where applicable, recode it back
to the ECU. Optional Vehicle Technical
Information package includes wiring
diagrams, guided diagnostic test
procedures and component locations.
Access to training, technical support
and online information.
A global leader, we now hold
more than 30 patents in MAF
sensing technology and signal
processing, including a proprietary
Temperature Compensation circuit
design, the world’s best T-Comp
technology. Today, Delphi has
delivered more than 50 million OE
MAF sensors for more than 500
customer applications.
Better still, we now supply an
extensive range of complete
MAF sensors for the aftermarket.
By testing and calibrating to OE
specifications, our aftermarket
sensors provide the same accurate
readings and airflow output as
the OE. And with Delphi you get
access to the complete package:
The range, covering more than 25
million vehicles in Europe, OE-level
diagnostics, and expert training and
technical support.
So why wouldn’t you choose Delphi for your aftermarket needs?
Did you know that Delphi has been producing OE Mass Airflow (MAF)Sensors since the 1970’s?
A MAF sensor, also known as an “air meter,” measures the air
coming into the intake system and transmits this information to the
ECU. The ECU utilizes the MAF sensor output signal to precisely
schedule fuel injection, creating an optimal air-to-fuel ratio. This
results in reduced emissions and improved fuel economy, all whilst
maintaining drivability.
What is a MAF Sensor.
Why do MAF sensors fail?
Contamination is a key reason
why MAF sensors fail and require
replacement. As air, dirt and other
debris get into the sensor, the
parts become contaminated and
fail. Drivers often notice sluggish
performance, rough idling, poor
acceleration or even stalling. There
may also be a more frequent need
to refuel. Other common failure
problems include:
Contact fault at the
electrical connections.
Damaged measuring elements.
Mechanical damage (vibrations,
accident, etc).
Measuring element
drift (exceeding the
measuring framework).
Symptoms of failure.
“Check engine” or “service
engine soon” light is on.
Hesitation / stall on
rapid acceleration.
Poor engine running at
idle and/or surge.
Excessive vibrations
when stationary.
Noticeable changes to
RPM without driver input.
Troubleshooting a MAF sensor.
Conduct an electronic test of the mass air flow
sensor by the engine management control unit. If
a fault occurs, a fault code is stored in the control
unit and can be obtained using a diagnostics unit.
Check the connector for a correct fit
and good contact.
Check the mass air flow sensor for damage.
Check the measuring elements for damage.
Check the voltage supply with the ignition
switched on (circuit diagram for pin assignment is
necessary). Ref. value: 7.5-14 V.
Check the output voltage or frequency with the
engine running (circuit diagram for pin assignment
is necessary). Ref. value: 0-5V resp. 0 – 12.000 Hz.
Check the connection cables between the
removed control unit connector and sensor
connector for transmission (circuit diagram for pin
assignment necessary). Ref. value: approx. 0 ohm.

Troubleshooting Turbos.Common Failures.
Turbo Replacements.What to Do and Not to Do when Replacing a Faulty Turbo.
DO.
Check the entire air supply system, including the EGR valve and
intercooler, for evidence of debris or damage. Clean thoroughly
and replace where necessary.
Perform an engine oil and oil filter change, observing for evidence
of oil contamination.
Inspect, clean, and replace where necessary the turbo oil feed
and return lines.
Check, and replace where necessary, the vehicle’s air
filter element.
Ensure that the internal bearings are thoroughly pre- lubricated
with priming oil (supplied with all Delphi turbos), and that the
supply of fresh engine oil to the turbocharger is immediate and
uninterrupted before starting the vehicle.
Perform an engine oil pressure check to ensure that the
lubrication system is performing to OE specifications, where
feasible to do so.
Replace all seals and o-rings when re-fitting a
turbocharger with new items (supplied with all
Delphi turbos), paying particular attention to the
orientation and position of any gaskets used.
Maintain a systematic, clean and thorough
approach when dealing with a turbocharger
fault, keeping in mind the potential
consequences of a mechanical failure.
DON’T.
Remove the protective caps or covers from the replacement
turbocharger until each respective pipe/hose is to be fitted.
Use liquid sealant at any joint or mating face associated
with the air or oil system. Liquid sealant is liable to
displace and block oilways, and may harden and fragment
into the turbocharger’s rotating assembly, causing
irreversible damage.
Adjust the actuator or linkage mechanism. All Delphi
turbochargers are 100 percent set and calibrated
to OE specifications. Any such adjustment will
invalidate the warranty.
Disassemble the turbocharger in any way. As specified in
the core acceptance criteria defined by Delphi (DM0932),
disassembled turbochargers are not liable to be accepted for
a core surcharge refund.
Replace the turbo without first identifying and
rectifying the root cause of the initial failure.
Not doing so could lead to repeated
failures and extensive engine damage.
This is costly to your business, time
consuming to your customer and worse
still, damaging to your reputation!
Understanding Turbochargers.
The turbocharger is an integral part
of the engine’s air and oil supply
systems; any mechanical failure can
result in extensive damage, and time-
consuming repairs.
Simply replacing a problematic turbo
will not guarantee that the original
problem is solved.
It is therefore essential, when faced
with a turbocharger failure, that the
necessary investigations are conducted
to establish the root cause of failure,
along with any necessary repairs and
preparations to minimise the risk of a
repeated failure occurring.
Likely symptoms of a Turbo Fault.
The common symptoms of a
turbocharger-related problem may
include, but are not limited to,
the following:
Progressive or sudden loss of power.
Low boost pressure.
Black or blue smoke
from the exhaust.
Harsh metallic noises originating
from under bonnet.
Engine management fault light
(manifold pressure-related
fault codes).
If any combination of the above
symptoms is presented, the
turbocharger system and associated
parts should be thoroughly inspected
and replaced, if necessary.
Because 95 percent of turbo failures are caused by external problems, it’s important to understand and fix the root cause before you fit a new turbo.
The Delphi Turbo Difference:
High quality parts at a competitive
price, now with a 24-month guarantee.
Engineered and tested to OE standards.
Free fitting kit, including oil primer,
in every box.
Complete service package: Delphi
diagnostics, hands-on training and
technical support.
NEW industry leading catalogue,
part number DDCX127C, fully
integrated into TecDoc.
For Fewer Customer Comebacks:
Before fitting a new turbo, always determine what caused
the first unit to fail or you risk the replacement turbo failing
too! Watch our video to learn more about turbo mode failure:

One of these injectors has been repaired using OE-approved test plans, equipment and parts for optimum performance and fuel efficiency. The other hasn’t. The result? Increased fuel consumption, reduced engine performance and shorter life. Even worse - a very dissatisfi ed customer. For OE-approved repairs you can trust, choose the Delphi Diesel Centre network.
Just like this sandwich, Delphi brake pads are packed with quality ingredients. Five layers of quality to be precise. And each one is designed to meet the OE’s appetite for braking performance, consistency and longevity. For five layers of quality you and your customers can trust, ‘tuck-in’ with Delphi.
A Little Extra Change?But a Big Change for the Environment.
Look out for......the ‘ leaf symbol’ on our packaging labels for low copper content pads.
Why the change?
Every time you press the brake pedal,
a small amount of copper and other
metal is deposited onto the road. When
it rains, this is washed into nearby
streams and rivers. With millions of
drivers using their brakes day in, day
out, it is estimated that brake pads
account for up to half of the copper
entering water systems in urban areas.
And with copper known to be very
toxic to aquatic life, this can cause
significant damage to the environment.
What have we changed?
When it comes to braking, copper
is intrinsically difficult to replace,
as it acts as both an abrasive and
lubricant in the friction mix. Yet as a
result of our continuous research and
development programme, our CF rear
wheel friction formulation, used in
popular pads such as LP565, is already
copper-free. And we’ve achieved all
this without compromising on vehicle
performance or safety. Better still,
our new formulation offers improved
fade performance, and unlike some
competitor brands, retains all its life
too. That’s a change for the better you
can put your money on.
Why this matters to you!
We all know price and safety are
important when it comes to retaining,
and even, gaining new braking
business. But there are other important
considerations too. The introduction
of premium, environmentally friendly
copper-free brake pads is yet another
reason, in an ever growing list, of
why you and your customers should
choose Delphi.
Starting January 2025, legislation will dictate that brake pads must contain no more than 0.5 percent copper, whilst still meeting the same rigorous safety standards. Just like vehicles fitted with Delphi brakes, we have stopped sooner.

Coast-to-Coast with Delphi.
In March 2015 Delphi completed the longest automated drive in North America, traveling from San Francisco to New York in the first coast-to-coast trip ever taken by an automated vehicle. Nearly 3,400 miles were covered with 99 percent of the drive in fully automated mode.
The drive was used by Delphi
engineers to research and collect
information that will help further
advance active safety technology – the
most rapidly growing technology sector
of the auto industry. The team collected
nearly three terabytes of data—about
30 percent of all of the printed material
in the Library of US Congress.
“Our vehicle performed remarkably
well during this drive, exceeding our
expectations,” said Jeff Owens, Delphi
chief technology officer.
“The knowledge obtained from this trip
will help optimize our existing active
safety products and accelerate our
future product development, which
will allow us to deliver unsurpassed
automotive grade technologies to
our customers.”
The nine-day trip crossed 15 states and
the District of Columbia. Along the
way, the vehicle encountered complex
driving situations such as traffic circles,
construction zones, bridges, tunnels,
aggressive drivers and a variety of
weather conditions.
Delphi’s automated driving vehicle,
aptly named Roadrunner, is equipped
with a full suite of advanced
technologies and features, many of
which are already on the market today
including collision mitigation, integrated
radar and camera systems, forward
collision and lane departure warning.

Delphi bushes are manufactured to OE quality standards and should be fitted according to the manufacturer’s instructions to avoid premature failure!!
Steering You Down the Right Path.Best Practice Advice for Replacing Suspension Arms Fitted with Horizontal Bushes.
Are you fitting horizontal bushes correctly? We hope so. But just in case, here’s some simple, best practice advice. Following these
steps should ensure the safe and efficient installation of the part and avoid premature failure as a result of incorrect fitment.
What you need to know: Installation tips
1 Wherever possible carry out the
repair on a four post lift, using a
jacking beam to support the vehicle,
and appropriate wheel chocks to
ensure the vehicle does not move.
2 Always use the new mounting
nuts and bolts, where supplied,
and ensure that any mounting
locking devices, such as “nyloc”
nuts, are replaced.
3 Always consult the workshop
manual, and tighten all mountings to
the manufacturer’s recommended
torque settings.
4 When the control arm/wishbone
is fitted with horizontal bushes,
care must be taken to tighten the
bush bolts when the vehicle is at
its neutral ride height i.e. with the
vehicle sat on its wheels and the
suspension settled.
5 Never tighten the bush bolts with
the vehicle in the air. This will lead
to excessive ‘wind up’ of the bushes
once the vehicle is returned to its
neutral ride height and when the
suspension is under compression,
and ultimately premature bush failure.
6 If in any doubt, consult the
manufacturer’s workshop manual
prior to carrying out any work.
And why? What happens if
bushes are not fitted correctly?
The bush will become over-
stressed leading to tears
in the rubber.
The bush loses resistance
and secure location, leading
to MOT failure.
Poor handling and a knocking noise
may be apparent during operation.
The Construction of a Rubber to Metal (RTM) Bush.
Rubber is moulded between the centre and outer tubes.
RTM bush does not function like a plain bearing.
There is no friction between surfaces.
During operation on the vehicle, the outer tube rotates
relative to the inner tube and the moulded rubber flexes.
...includes more than 500 new references, with a significantly extended range of rubber to metal parts.
These cover popular applications such as BMW 5 Series, Honda Civic, Mazda 6, Kia Optima, Nissan Juke, Volkswagen Amarok and many, many more.
WRONG FITMENT. ARM UNDER COMPRESSION.
WRONG FITMENT. ARM HANGING OR UNDER EXTENSION.
RIGHT FITMENT. NEUTRAL RIDE HEIGHT.
Failure of a Bush Due to Incorrect Installation.
Incorrect tightening of the mountings has resulted in the bush being over stressed leading to tears in the rubber and failure of the bush.

Social Media. A Business Tool Too Powerful to Ignore.
Why Companies Need Social Media.
1 Brand Recognition: We’ve all heard
the saying ‘out of sight, out of mind.’
In business, if you aren’t consistently
reminding your customers who you
are, why you’re different from the
competition and what you have to
offer, they will forget about you and
go elsewhere.
Social Solution: Establish your
brand as an industry expert, the
go-to company for questions. Use
your company social presence to
share regular tips, advice, and links
to interesting or industry-related
articles. Reinforce your brand voice
as an industry authority. Post one tip
or link per day with images during
a time that you know your fans
/ followers are online. According
to a HubSpot study, not only do
photo posts get more engagement
than links, videos or text-based
updates, they actually account for
93 percent of the most engaging
posts on Facebook.
2 Customer Insights: Unsure what
your customers are thinking but
don’t have the time or money to find
out? Social networks are a great way
to learn about what is motivating
your customer and prospects.
Social Solution: People commonly
use social networks as a place
to say what they’re thinking and
feeling. If they like a product or
have a problem you’ll hear about it
in a social post. Listening to these
conversations taking place on social
media can help you identify the real
and immediate needs and concerns
of your customers.
Want a pulse check on what your
customers are thinking? Post a
multiple choice question or ask what
your audience is thinking about X,
Y or Z topics.
3 Promotions and Sales: Struggling
to reach your target audience to
generate sales?
Social Solution: Some social
networks offer tools that allow
you to geo-target. This can be an
effective way to send promotions
out to a specific audience based on
their location. To identify additional
groups to target, search to see
what conversations are taking
place around a topic related to
your product or service. Be ready
to comment on conversations in
these forums in a neutral, non-
marketing manner.
4 Website Traffic: You’ve launched
a website for your company but no
one knows it’s live.
Social Solution: Broadcast the
launch on your social networks
encouraging your social connects
to help you spread the word. Then,
continually promote the website
when posting content by adding
links back to your website where
users can get more information.
Provide updates when new content
is posted, new promotions are
launched or there is news to share.
5 Search Engine Optimization
(SEO): Your website’s SEO ranking
is low causing limited visibility in
search engine results.
Social Solution: SEO ranking can
sometimes be affected by your
social networks. As your social
following grows, so could your SEO
score and visibility in search engine
results. Your social networks can
also be used to increase inbound
links, one of the major factors used
by search engine algorithms to rank
your website. A quick way to create
these links is to post content that
links directly back to your website.
Remember, you want your audience
to click on the link so be sure the
content you post is engaging.
Social media is not a fad, it is a fundamental change in how we communicate – not only personally, but in business.
At Delphi Product & Service
Solutions we’ve implemented
a social strategy that includes
profiles on Facebook, Twitter,

Tough, Tested and Built with OE Innovation.You’ll Never Get Wound-Up by Delphi Ignition Coils.
Winding the wire: Why it matters.
Much like a kite string should be wound
evenly along its spool, ignition coil
windings should be evenly distributed
and neatly wrapped, so voltage is
consistent and the most magnetic
power can be drawn out.
More length of wire generates
differences in voltage, which in turn
creates pressure that causes the
breakdown of insulation and wire
coatings. So Delphi has developed a
process to tightly control the length
of the wire between adjacent primary
and secondary windings. Just as
important, we ensure that both the
primary and secondary windings are
wound to the steel core as closely and
smoothly as possible.
By controlling the winding length
and ensuring proximity to the core,
we’ve developed ignition coils that
help drivers experience better engine
performance and fuel efficiency. This
level of design and manufacturing
sophistication cannot be matched
by many manufacturers, but you can
count on Delphi to deliver the highest
quality OE standards.
We put 100 years of under-the-bonnet experience into every ignition coil we make. We’re proud to offer ignition coils for all makes that are built using world-class winding technology—which means they provide peak power, OE performance, and 100 percent satisfaction for you and your customers.

After all, it allows you to drive further, with less fuel, whilst still enjoying a more powerful ride. All this makes the recent opposition to this
technology even more remarkable. Here we aim to dispel some of those common, often ill-informed, misconceptions with a few key home
truths about diesel.
1 Diesel has the lowest Carbon
Dioxide (CO2) emissions of
current fuel sources:
› Diesel fuel has higher energy content
per liter than other transport fuels.
› The way diesel burns is well suited
to compression-ignition engines,
which have a higher thermodynamic
efficiency than gasoline spark-
ignition engines. This means they
convert more of the energy content
of the fuel into useful work.
› Because of these two key
factors, diesel cars consume about
25% less fuel by volume than
equivalent gasoline cars.
› Diesel cars also generate about
15% less CO2 per kilometer than
equivalent gasoline cars.
2 Diesel is a key contributor to
meeting CO2 reduction goals:
› Road transport contributes
to about 20%[1] of total
man-made greenhouse gas
emissions, mainly CO2.
› Vehicle makers rely on continued
diesel share to reduce fleet
average CO2 emissions to
95g/km for passenger cars by
2021 and to 147g/km for light
commercial vehicles.
› Diesel will help to further reduce
CO2 emissions beyond 2021.
3 Diesel is a cost-effective and
popular solution for many users:
› Diesel’s high fuel economy ensures
lower fuel costs and longer range
between refueling stops.
› Diesel engines provide high torque,
enabling load-carrying, towing, and
safe overtaking.
› In 2013, approximately 50% of new
passenger car buyers in Europe
chose diesel versions[2].
› Diesel remains the predominant
fuel source for heavy and light
commercial vehicles.
4 Clean diesel technology
successfully controls
emissions including under
real-world conditions:
› From September 2015, all new
cars and from September 2016, all
light-commercial vehicles registered
in the European Union (EU) must
comply with the Euro 6 emissions
standard, measured over the official
test cycle (NEDC).
› Emissions of Particulate Matter
(PM), including soot, are reduced
by 97% (EU1 140 mg/km versus
EU6 4,5 mg/km).
› From 2017, the limit values for
particle numbers will be the same
for diesel and gasoline.
› Since measurement of Nitrogen
Oxides (NOx) emission levels in Euro
3 (2000), NOx are reduced by 84%.
5 ‘Real Driving Emissions’
(RDE) testing will further
reduce emissions:
› Emission tests on roads have
already been introduced for heavy
commercial vehicles (HCVs).
› As a consequence, new HCVs
emit low emissions level in real
driving conditions.
› Due in part to these measures,
total NOx emissions from road
transportation in the EU in 2015
are expected to be 40% lower than
2005 levels[3].
› RDE testing is expected to become
mandatory for passenger and light-
commercial vehicles from 2017.
› Introduction of RDE test will
lead to significant reduction of
NOx emissions from light
duty vehicles[4].

[4] Assuming new vehicles stay within 50% of Euro 6 limits in real driving conditions from 2017, the total NOx emissions from all light-duty diesel vehicles will be cut by 30% from 2015 to 2020, and by 57% from 2015 to 2025
What is Euro-6?
Since 1992, the European Union has
imposed increasingly strict limits on
emissions from cars. As the name
suggests, Euro-6 is the sixth version of
these standards, and from 1 September
2015 all new cars must meet these
limits. A Euro-6 car produces a lot less
pollutants than those from a Euro-5 car,
and just a tiny fraction of those emitted
from a Euro-1 car.

High Performance Brake Grease that’s Up to the Job.
24 TechTalk
There’s a widespread view that copper grease, otherwise known as copper slip, should be applied to the back of brake pads to help lubrication and noise prevention. Not so. The need for copper grease has diminished in recent years in line with advances in shim technology.
In fact, its use could have the opposite
effect, preventing the shim, the basis of
quiet braking, from doing its job. The
result increased noise and judder, as
well as possible interference with the
electrical systems such as the ABS,
ESP wear sensors etc.
So Why Take the Risk?
Formulated from a non-mineral
oil based solution, Delphi’s
high performance brake
grease replaces the need
for traditional copper-based
variants, whilst also reducing
noise and preventing squealing
and chatter for the life of
the brake job.
Why choose Delphi brake grease?
Free of copper and acids, avoiding
the risk of corrosion.
Non-conductive eliminating
interference with
electrical components.
High pressure stability
helping to ensure longer-term
lubricating properties.
Compatible with all metals
and most rubber materials for
universal application.
Resistant to high temperatures and
water for increased protection.
Long-lasting protection against
corrosion, with no visible
residue or staining.
Supplied in a handy 100ml tube,
with applicator for easy application.
For a professional brake installation,
Delphi brake grease should be applied
sparingly to the metal-to-metal contact
points between the brake pad and
caliper only. But remember, never
coat the pad’s friction material or the
surface of the disc, and always keep
clear of all rubber parts.

The components of a braking system
are subject to considerable stresses,
even under normal driving conditions.
Over time they will naturally wear,
which means they’ll become less
effective at slowing and stopping
the vehicle. Dirt, driving style and
conditions could all help to accelerate
this. So it’s important that you are
able to spot any signs of wear and
tear at the earliest opportunity.
Check out our handy guide opposite
for advice on what to look out for and
how to fix it.
Brakes you can trust.
Because your customer’s safety
depends on brakes that work, you
won’t want to skimp when it comes
to replacing their old, worn out
brakes. So don’t! Choose a quality
brand, designed, engineered and
manufactured to OE specifications.
Choose Delphi for:
Shorter stopping distances: Tests
have proved that Delphi brakes stop
quicker than other brands.
Quieter braking: With a unique
underlayer and OE noise fixes, Delphi
brakes are quieter than ever.
Longer lasting: Designed to deliver
optimum wear without compromising
on performance.
Engineered for the vehicle: With
20 unique friction formulations, made
from over 130 ingredients, Delphi
brakes are designed to match the
vehicle application.
Superior finishing: Aids “bedding”
of brake pads to disc for maximum
braking efficiency.
Put your foot down: Compression
tested pads for consistent and
confident pedal feel and greater
driver comfort.
Delphi always recommends the use of a new fitting kit when replacing pads, discs, or calipers. For more best practice advice on diagnosing braking faults, visit delphiautoparts.com
48-Volt.A Missing Piece of the Puzzle to Less CO2?
For an industry that has tried everything from 300-600 volts with pure electric vehicles, plug-in hybrids and big lithium-ion batteries, a widespread 48-Volt strategy may offer the biggest bang for the buck.
Europe is calling for CO2 emissions
reductions of more than 25 percent by
2021 and regulations in China and the
U.S. will require tighter CO2 mandates
over the next decade.
“Compared to higher voltage mild
hybrids, vehicles with 48-Volt systems
have demonstrated 70 percent of the
benefit at 30 percent of the cost,”
said Jeff Owens, chief technology
officer. “Delphi’s goal is to exceed the
benefit by maximizing the use of the
48-Volt architecture to deliver enhanced
overall performance.”
48-Volt mild hybrids, for gasoline
or diesel engines, could reduce the
percentage of CO2 emissions by
double digits, capture energy typically
lost while braking and provide torque
in the low rpm range for anemic
start-stop hybrids.
The beauty of a 48-Volt solution
is that drivers will not lose engine
performance to gain fuel efficiency
from downsized engines. Consumers
would drive these 48-Volt cars the
same way they would drive cars
powered by conventional powertrains,
and they would enjoy the 20 percent
extra horsepower the 48-Volt
system provides.
Great Benefit at a Low Cost.
48-Volt Mild Hybrid
Though a mild hybrid can be configured
in many ways, here is one example of
a cost effective, lower CO2 emitting.

regenerative braking.

How does Coding Affect the Repair of Injectors?
When an injector is repaired, its
characteristics will be significantly
changed. It is therefore critical that a
new code is allocated to reflect the
performance of the repaired injector.
The ECU must then be re-programmed
with this code when the injector is
fitted to the vehicle. This will ensure
that the adjustment to the pulse times
is made and that the correct fuel
delivery is maintained. Failure to do this
will mean that the ECU will continue
to work with the previous injector’s
characteristics, leading to issues such
as reduced power, excessive smoke
and increased engine noise.
The generation of this code is a
complex procedure. Only members of
the authorised Delphi Common Rail
repair network possess the specialist
equipment and software required to
accurately generate them.
Where to find a Correction Code?
The injector’s individual correction
code takes the form of a 16 digit,
hexadecimal code for C2i, or a 20 digit,
alphanumerical code for C3i and can
be found on either a label stuck
to the body, or engraved on a
plate on the injector.
Does your Injector have Delphi DNA?
What is an Injector Correction Code?
All Delphi Common Rail injectors feature
either an Individual Injector Correction
(C2i), or an Improved Individual Injector
Correction (C3i) code. This unique code
relates to the specific characteristics
of each injector such as flow rates,
response times and performance at
different pressures, and is designed to
allow precision management of the fuel
injected into each cylinder for optimum
engine efficiency, and to enable the
ECU to be calibrated with the injection
system. It is recorded to the injector
during manufacturing, and subsequently
programmed to the ECU during
vehicle assembly.
Why are Correction Codes so important?
It is impossible to produce injectors
that are absolutely identical. Operating
at extremely high pressures, even
minute physical variations between
injectors will cause discrepancies in the
amount of fuel delivered by each. This
in turn will result in inefficient engine
performance, which could lead to
reduced power, increased engine noise
and excessive smoke. The amount of
fuel that is delivered by the injector
is proportional to the injection time
(pulse) and rail pressure. Therefore,
it is possible to compensate for
manufacturing variances by managing
the pulse time applied to each injector.
Delphi’s correction codes are generated
by measuring the flow rate of each
injector at five different pressures
for C2i (230, 400, 800, 1200 bar
and maximum pressure) and three
different pressures for C3i (400, 800
bar and maximum pressure). These
measurements are then compared
against a target (average) injector
performance to assess what pulse
time adjustment is required in order to
obtain the required fuel delivery. This
adjustment is translated into the code.
Simple your reputation is at stake!
Installing an injector that has been
repaired with sub-standard components
or processes could have a significant
impact on engine performance.
The result? Increased fuel use,
emissions and wear and damage.
Not forgetting an unhappy customer.
