What are the Key Differences Between MPFI vs Carburettor Engine?

Carburettor Engine vs MPFI Engine: Differences in Key Components

Key Components of Carburettor Engine

1. Throttle Valve: This is the valve that regulates the amount of fuel-air mixture that passes into the combustion chamber.

2. Choke: The role of the choke is to regulate the amount of fuel in the combustion mixture, usually to make it richer for starting.

3. Float Chamber: This is the reservoir that holds the fuel and delivers it as needed. It has a float valve that is used to regulate the level of fuel in the chamber.

4. Mixing Chamber: This is the chamber where the air and fuel are mixed to make the final fuel-air mixture.

Key Components of the MPFI Engine

1. Engine Control Unit (ECU): This is the main component of an MPFI engine. The ECU controls and regulates different parameters necessary for fuel injection.

2. Fuel Pressure Regulator: This regulates the fuel pressure and is responsible for smooth fuel injection.

3. Sensors: There are a number of sensors that are an essential part of the system. These include oxygen sensors, position sensors, temperature sensors and many more.
