THE CHALLENGE

The 1998 Consent Decree affecting all Heavy Duty engine manufacturers in the US initiated the need for Portable Emissions Measurement Systems (PEMS). Since then, applications have substantially expanded throughout the world, including:

• Continued compliance and in-use conformity testing against regulatory standards

• Validation of powertrain and exhaust system design• Development of air shed inventory models• Determination of real world fuel economy• Investigation of contributions of certain air toxins

In particular, heavy duty fleet in-use compliance testing has spread from the US into Europe and Asia, ensuring that vehicles continue to meet regulatory standards.

Recently, the European Union promulgated EU6(c), which demands that all passenger cars be tested under real world conditions as part of the certification process.

According to the Union of Concerned Scientists, “today’s on-road vehicles produce over a third of the carbon monoxide and nitrogen oxides in our atmosphere.” (03-Sep-2013)

EASE-OF-USE

The SEMTECH® LDV is designed for ease-of-use and flexibility. Core modules consist of the SEMTECH® GAS, measuring CO, CO2 , NO and NO2, the SEMTECH® SCS, containing the Sample Conditioning System, and the Exhaust Flowmeter, EFM4.

The system may be mounted on a tow bar, with a quick clamp to the vehicle, or in the vehicle trunk. Externally mounted systems are sheltered with an aerodynamic cover, which shields it from the elements while minimizing drag on the vehicle.

Sample lines, pneumatics, and cables are minimized with modules that mate directly via electrical and pneumatic connections. Lines are specially designed to allow the trunk to be closed over them.

The system is controlled from the SEMTECH® ICM, In-vehicle Control Module, which doubles as a driver aid and in-vehicle communications platform. The ICM features an easily accessible E-Stop and event marker, and connects wirelessly to a personal computing device for snapshot views of system status, recording and route criteria monitoring.

The SEMTECH® LDV has been designed and tested to ensure that it may be deployed safely under the most extreme conditions.

Toxic Gases: Sample lines exhaust the sample gas outside the vehicle, even if the system is installed inside the vehicle. The use of flat heated lines enables the trunk or hatch to be closed during operation, minimizing the risk of exhaust vapors seeping into the vehicle cab during on-road testing.

Heated Surfaces: All potentially heated surfaces, such as the EFM4 tube assembly, include heat shields to protect from accidental contact with any hot surface.

High-Speed Operation: Carrier and tow bar specifically developed for the SEMTECH® LDV will be submitted to the Dutch RDW for certification.

Electronics: All power lines used are 12 VDC. Power cables have been replaced by Power-Over-Ethernet where possible, to power up ancillary modules.

In-Vehicle Emergency Stop: The driver can cut power to the entire system using the emergency stop of the In-vehicle Control Module (ICM).

SAFETY

Safety is a primary design obligation. Sensors has incorporated innovative solutions to mitigate all known potential safety issues.

Sensors has incorporated fifteen years of PEMS experience to simplify operation of the SEMTECH® LDV system, with unique and innovative solutions.

Heated Line: The heated line is a new, modular, micro-processor controlled series of devices that are low power, versatile and durable. Build custom sample lines by connecting straight sections with Flat-, T-, Y- and Right-angle- shaped connectors. Each module is independently monitored and controlled.

Host Software: The host software is an intuitive, browser-based, multi-user interface designed for routine PEMS operation with minimum of training.

Most operational and reporting tasks are automated, ranging from QA/QC tasks such as linearity verification, to data post-processing and reporting.

Calibration: Connect the SEMTECH® LDV system to shore power and to the SEMTECH® CAL 7-input gas port calibration module to run automated calibration procedures. The system can be programmed to run the procedure at a set time, ensuring that the LDV is ready for RDE testing when you are.

Foreseeing all regulatory changes over the entire life cycle of a PEMS analyzer can be challenging. Opting for a non-scalable PEMS solution can prove costly when new regulations require new analytical capabilities only a few years into the life cycle of the analyzer.

The SEMTECH® LDV network-enabled architecture is scalable, so that it can adapt to these changing regulations. At the core of the system is a web server collecting all data from all Ethernet sub-assemblies and modules, whether internal or external, in real-time, and transferring them to the local processing engine for diagnostics and data treatment. Results are then posted in real-time to web pages, which are streamed to any personal computing device with a browser, such as a tablet, laptop or smart phone.

Adding a module to the LDV system is simply a matter of plugging in another web appliance, or data node, to the analyzers’ local network. Additional modules may include:

• FID• Dual FID• CPN - Continuous Particle Number Module• Calibration Module• I/O Module

This flexibility in configuration offers expandability of the initial SEMTECH® LDV solution over a long period of time.

SCALABLE ARCHITECTURE

Anticipating tomorrow’s needs, the platform architecture is expandable, accommodating additional analyzers, upgrades and other accessories with ease.

The SEMTECH LDV employs Sensor’s vehicle communications interface (VCI), setting the industry standard for reliability and ease-of-use.

Built into the ICM (In-Cab Control Module), the VCI takes the guesswork out of interfacing to the vehicle. Upon connection, the VCI will auto-detect the vehicle’s protocol and baud rate. Then the VCI will query the ECM to determine which data points are supported.

These enhancements enable the smoothest user experience possible. When creating the list of data points to include in a test file, the user is presented with live streaming values for all data points that

the ECM supports. Adding a data point to the list of points to be logged is as simple as checking a checkbox!

The simplicity of this experience is also available to our advanced users. When entering proprietary data points or DMRs, the user is shown a live value, allowing them to confirm proper setup and detect configuration errors early.

The VCI is quick too! It’s able to stream vehicle data as soon as the ECM makes it available, allowing it to perform as quickly as any other commercially-available vehicle interface device.

VEHICLE COMMUNICATIONS INTERFACE

The Vehicle Communications Interface simplifies ECM connectivity quickly and reliably.

Real-Time Data Processing: The new SEMTECH® host software provides immediate access to information critical to the completion of a successful test sequence, including essential real-time hardware diagnostics, to ensure that all conditions are met. This critical real-time test information is available simultaneously to multiple users.

Post-Processing & Reporting: Data Processing and reporting are accomplished with one click of a button using the powerful SensorTECH Pro and SensorTECH CT software packages.

Sensors’ data capture and post-processing software packages allow:

• Recording and automated time alignment of data from various inputs, such VI, GPS, SEMTECH® GAS, etc.

• One-click post processing and reporting in accordance with all known RDE standards (EMROAD and CLEAR)

• Automated QA/QC of all processes

DATA ACQUISITION AND ANALYSIS

Real-time diagnostics save time and money, ensuring reliable results.

The core of the SEMTECH® LDV data structure is a web server located in the Sample Conditioning System, which provides offers the following features:

Data Management: All information generated by each sub-assembly in the SEMTECH® LDV analyzer is gathered in real-time, and immediately available for access from any personal computing device with web-browsing capabilities. A smart-phone or tablet can be used to start a calibration, view data or check the analyzer status. No laptop is required for routine operation of the SEMTECH® LDV.

Analyzer Control: A unique multi-user management system enables access to the analyzer by multiple users, simultaneously, without conflict. For example, a technician can calibrate the system, while an engineer verifies vehicle interface protocols.

Hardware Integration: Accessories, such as GPS, weather probe, SEMTECH®CAL and video camera, can be added to the stack as Ethernet appliances. Similarly, installing additional modules, such as the CPN or Dual FID, involves plugging in another Ethernet appliance to the analyzers’ local network.

BROWSER ACCESSIBLE MONITORING AND CONTROL

Monitoring and control can be performed with any operating system, using any web browser.
