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

Fuel supply systems are categorized as follows:

1. Carburetor System: An older method that combines fuel and air prior to combustion within the engine.
2. Fuel Injection System: A contemporary method that precisely injects fuel at high pressure into the combustion chamber or intake manifold, leading to enhanced fuel atomization and more efficient combustion.

• Electronic Fuel Injection (EFI): This system leverages electronic sensors and control units to regulate fuel delivery according to engine demands.
• Direct Injection: Fuel is introduced directly into the combustion chamber, resulting in improved efficiency and increased power output.

The fuel injection system is favored due to its accuracy and capacity to optimize fuel economy while minimizing emissions.
