Diagnosing Common Causes Of Engine Failure

Page 2: Diagnosing Common Causes Of Engine Failure

Engine failure is always a stressful scenario for everyone. But smart choices always make us less vulnerable to expensive

repair.

Page 3: Diagnosing Common Causes Of Engine Failure

The more you ignore the problem, the more tricky it will become to diagnose. Also it takes more time to repair the

issue.

Page 4: Diagnosing Common Causes Of Engine Failure

Let's know how it works ---

Page 5: Diagnosing Common Causes Of Engine Failure

The engine coverts the gasoline to energy through combustion process which makes the vehicle run.

Page 6: Diagnosing Common Causes Of Engine Failure

It's also a universal truth that rough driving and the ignorant driver can kill the engine.

Page 7: Diagnosing Common Causes Of Engine Failure

Let's have a look on the causes of engine problem :-

Page 8: Diagnosing Common Causes Of Engine Failure

Improper oil change schedule :-

Vehicle needs oil change in right time which can protect the engine and its components from getting rusty and remove

excess heat.

Page 9: Diagnosing Common Causes Of Engine Failure

Irregular oil change causes the engine to overheat and that results in a poor fuel economy.

Engine starts to show problem when you add lower octane level oils than prescribed in owner's manual.

Use of lower octane fuel :-

Page 11: Diagnosing Common Causes Of Engine Failure

The bad fuel can clog the intake valve, spark plug etc which results in improper fuel delivery and misfire.

Page 12: Diagnosing Common Causes Of Engine Failure

As per owner's manual, make sure to use recommended additive and right octane fuel that will give a better fuel

economy.

A leaking oil pump can cause misfire and loss of fuel within a very limited period of

time.

Oil Pump Failure :-

Page 14: Diagnosing Common Causes Of Engine Failure

The leakage also can cause overheat as the right amount of fuel doesn't get delivered to

the combustion chamber.

Page 15: Diagnosing Common Causes Of Engine Failure

Spark knock happens due to excess heat generation at time of combustion due to improper fuel ratio.

Spark knock:-

Page 16: Diagnosing Common Causes Of Engine Failure

When spark knock starts, it generates a metallic knocking or pinging noise as a symptom of this issue.

This sensor measures the amount of oxygen left unborn in the exhaust.

Faulty oxygen sensor :-

Page 18: Diagnosing Common Causes Of Engine Failure

This problem of improper oxygen leads to lower gas mileage and release of harmful gases to environment.

Page 19: Diagnosing Common Causes Of Engine Failure

The leaking coolant or lower coolant level can harm the engine while engine overheats at time of combustion.

Coolant leaking :-

Page 20: Diagnosing Common Causes Of Engine Failure

Make sure to keep the coolant in its appropriate level and the cooling system in good working condition.

Page 21: Diagnosing Common Causes Of Engine Failure

When spark plug gets worn out, it causes misfire and loss of fuel economy.

Worn out spark plug :-

Page 22: Diagnosing Common Causes Of Engine Failure

The misfire also leads to damage of other engine component due to overheating.

Page 23: Diagnosing Common Causes Of Engine Failure

The loosen gas cap can give potential risk of gas evaporation from the vehicle.

Loosen gas cap :-

Page 24: Diagnosing Common Causes Of Engine Failure

This problem ultimately leads to decrease the gas mileage and give you a potentially expensive repair bill.

Page 25: Diagnosing Common Causes Of Engine Failure

Sometimes the worn out engine bearings can cause the engine not to start and this only can be avoided by a thorough servicing

and maintenance.

If the piston ring is worn out then it also makes the engine not to start after

a proper combustion.
