Working of EFI(electronic fuel injection system)

The EFI system consists of 2 main compartments Low pressure and High Pressure , the low pressure part consists of fuel tank,fuel pump,heater & cooler,fuel filter whilst the high pressure part consists of fuel injector,fuel injector nozzle,high pressure pump , fuel accumulator

here in this diagram we can see all the various parts of the system .

1. The fuel starts moving from the fuel tank because of the pump working to suck in the fuel from the fuel tank
2. After that the fuel travels through the filter , which filters out the unwanted materials from the liquid .
3. after that it travels to the injectors , giving fuel to the combustion chamber

4. we can see there is an accumulator present in-between the fuel filter and fuel pump , henceforth the fuel travels to the distributor

5. from there it goes through the inlet pipe and then the inlet manifold mixing with the air
