What is the job of the ECM in an electronic fuel injection system?
The ECM controls the timing and amount of fuel injected at a speed of 1000th of a second for optimal combustion. The ECM delivers precision control over the EGR system, including the EGR valve and air intake throttle as well to reduce NOx and particulate matter (PM) emissions.
What are the important units of electronic fuel injection system?
Electronic Control Unit (ECU) “Check Engine” Light / “Service Engine Soon” Light. Fuel Injectors. Fuel Pump.
How does an electronically controlled fuel injector work?
Electronically Controlled Fuel Injectors They are the fuel injectors in which the control of fuel speed, quantity, pressure and timing is done electronically with the help of electronic solenoid which takes the input either from fuel distributor or from electronic control unit (advanced one) of the vehicle. Construction of Fuel Injectors
What are the components of a fuel injection system?
Components of the Electronic Fuel Injection System include: 1 Sensors 2 Electronic Control Unit (ECU) 3 “Check Engine” Light / “Service Engine Soon” Light 4 Fuel Injectors 5 Fuel Pump
Where are the fuel injectors located in an engine?
The position of the fuel injectors differs for different engine designs but usually they are mounted on the engine head with a tip inside the combustion chamber of the engine. Why do we Need Them?
How to build a DIY Fuel injection ECU controller?
Only cut the signal wire, and connect the sensor side to your green “in” wire for the controller, and the other side going to the ECU to the brown “out” wire. Mount the unit in a location handy to adjust while driving.

How is fuel injection controlled by the ECU?
The injection is controlled by the ECU. It determines the amount of fuel to injected and in some system if the engine is cold, turns on an “extra” injector which only works while the system is cold. This injector only works for a short period of time determined by the ECU.
Where is the fuel injection information stored in the ECM?
The control functions for the fuel injection system are integrated in the engine control module (ECM). Each injector’s flow rate information and cylinder position are stored in the memory of both the glow plug control module (GPCM) and the ECM.
