What are the Warning Signs of a Faulty Fuel Injection System in the Car

The primary job of the fuel injection system is to deliver fuel to the engine.

In modern vehicles, the fuel injection system is regulated by a computer.

The computer uses data from different types of sensors located in the engine bay or inside the exhaust system.

Then, inject a calculated amount of fuel into each cylinder of the engine.

Fuel injection system has been differentiated into two broad categories:

Malfunctions in the fuel injection system could affect the power output of the engine in a very adverse way.

STARTING PROBLEMS

An engine won’t start in the absence of an adequate amount of fuel inside the combustion chamber.

This happens due to the inability of the fuel injection system to deliver the required amount of fuel to the engine.

Facing problems while starting an engine should never be ignored as it could lead to a serious problem.

ENGINE MISFIRE

The engine control unit regulates the timing and quantity of fuel injection.

However, clogged or faulty fuel injectors could not fulfill the requirement of the engine which could lead to the engine misfire.

Besides, a sudden drop in RPM is also a warning sign of a deformed fuel injection system.

CHECK ENGINE LIGHT COMES ON

Needless to say that any kind of malfunctions in the engine might trigger check engine light.

Although it could refer to a vast array of mechanical errors, a deformed fuel injector might be the one.

Besides, a sudden drop in power generation by the engine accompanied by the illumination of check engine light indicates that the fuel injection system has some errors.

POOR FUEL ECONOMY

An abnormal fuel injection system could overlook the commands provided by the ECU.

And it could inject an excess amount of fuel into the combustion chamber of the engine.

So, a sudden drop in fuel economy along with the reduction of power generation by the engine indicates that the fuel injectors have some problems.

EMISSION RELATED ISSUES

Injection of an excess amount of fuel into the combustion chamber might trigger several emission-related problems.

Emission of thick black smoke shows that the emission system or the fuel injection systems have some deformities.

Presence of a huge amount of unburned hydrocarbons in the exhaust gases also a clear sign of a failed fuel injection system.

Fuel injectors play a vital role in the process of power generation by the engine.

Errors in such crucial components of the car could have disastrous consequences.

So, signs which show that the fuel injection system has problems should not be ignored and timely action should be taken to fix such problems.
