Let’s put some light on the Fuel injection system. Here we have focused on the components and working process of Mechanical and Electronic fuel injectors, difference between them, some loopholes of Mechanical fuel injector and the basic functionalities of sensors. Have a glance.

6. Fuel
Distributor
CamshaftAccumulator

7. A fuel pump mounted near fuel tank sends fuel to
accumulator at the pressure of 100psi
Fuel passes through
fuel distributor

9. Let’s Know About The Loopholes Of
Mechanically Controlled Injectors

10. Less Power
Output : Mechanical
System can’t provide
high-pressure fuel to
engine

11. 2nd cause of less power generation :The Carbon Build Up
on intake blocks the airflow into the cylinder ..

12. Burn holes in catalytic converter: Due to disturbance in fuel flow ,the
carbon built up on intake increases day by day and this built-up causes
holes in catalytic converter

13. Produces high percentage of
Emission due to mechanical
injectors

14. Expensive :

15. Electronic Fuel
Injector

16. Electronic Injector System also possess
springs
Injectors opened By Electromagnet
system
The ECU determine the duration of getting
open and close of injectors

22. Air Pressure
Air Density

23. Air -Fuel pressure
Coolant Temperature

24. Timing
Speed

29. Is there any difference between Mechanical and electronic
injectors..???

30. Yes ………..Electronic injectors are controlled by complex-
microprocessor unit or a miniaturecomputer
But Mechanical System depends on the
data from airflow sensor alone …
