Question

Enumerate the various types of fuel supply system and explain fuel injection system.

Hint:

Fuel injection systems are more efficient and environmentally friendly compared to carburetors due to their precise control over fuel delivery.

Answer 1

The types of fuel supply systems include:

1. Carburetor System: A traditional system that mixes fuel and air before entering the engine’s combustion chamber.
2. Fuel Injection System: A modern system that directly injects fuel into the combustion chamber or intake manifold under high pressure, ensuring better fuel atomization and combustion efficiency.

• Electronic Fuel Injection (EFI): This system uses electronic sensors and controls to adjust the fuel delivery based on engine needs.
• Direct Injection: Fuel is injected directly into the combustion chamber, improving efficiency and power.

The fuel injection system is preferred for its precision and ability to optimize fuel efficiency and reduce emissions.
