Description

 

During cold starting, a microprocessor activates a specialized injector to add extra fuel into the mixture to facilitate smoother starts. Once the engine has warmed up, fuel from the cold start fuel injector is automatically cut off. This is different from a carburetor since you only need to block the airflow to create a richer mixture.

 

How do Electronic Fuel Injectors Work?

 

Many modern cars come with electronic injection systems. These are often denoted by the acronym EFI. In essence, these are almost the same as mechanical fuel injection systems except that they are not dependent on the amount of fuel and spring tension to open and close the valve of the injectors. What they do have are highly complex mini computers called Electronic Control Unit or ECU. The ECU performs a variety of functions, including the following.

 

It controls fuel mixture.
It controls idle speed.
It manages ignition timing.
It controls valve timing.


Sensors that measure air pressure, air intake temperature, accelerator position, engine temperature, and engine speed are mounted on the car’s engine. These sensors feed information to the ECU which processes these bits of data to compute the right amounts of fuel to be injected into the engine’s cylinders. The valves on the fuel injectors receive input from the ECU so that it knows exactly when to open to allow fuel to be squirted into the inlet port.

 

The system is so efficient that all of these complex processes – from the gathering of sensor data to its integration at the ECU level to its processing and its eventual input into the fuel injector valve – occur in a split second.

 

Following the journey of your fuel from the gas tank, it enters the fuel rail, thanks to an electric fuel pump that draws fuel from the tank. This is where another difference from mechanical fuel injectors comes in, by the way. Since fuel movement is controlled electronically, there is no need to have it at high pressure. The system only needs to maintain it at a constant pressure to deliver the fuel from the tank to the rail.
