WHAT IS MPFI &ITS WORKING

Question

Accepted Answer

MPFI stands for Multi-Point Fuel Injection. It is a fuel injection system that uses multiple injectors to deliver fuel to each cylinder individually.

MPFI is commonly used in modern gasoline engines.
It improves fuel efficiency, engine performance, and reduces emissions.
Each cylinder has its own fuel injector, which is controlled by the engine's electronic control unit (ECU).
The ECU determines the amount of fuel to be injected based on various sensor inputs such as engine speed, throttle position, and oxygen sensor readings.
MPFI provides better atomization of fuel, resulting in more efficient combustion.
It allows for precise control of fuel delivery to each cylinder, optimizing power output and reducing fuel consumption.
Example: A car with MPFI system has four cylinders, so it will have four fuel injectors.
Example: When the driver presses the accelerator pedal, the ECU increases the fuel flow to the corresponding injectors, providing more power to the engine.
