Question

In order to mix air and petrol in the required proportion and to supply it to the engine during suction stroke, then ____________ is employed.

(a) fuel pump

(b) injector

(c) carburetor

(d) none of the mentioned

This question was addressed to me in homework.

Query is from Comparison of Two Stroke S.I. and C.I. Engines topic in section Two Stroke Engines of IC Engine

Answer 1

The correct answer is:

(c) carburetor

 Explanation:

In a petrol engine, the carburetor is used to mix air and petrol in the required proportion and supply the mixture to the engine during the suction stroke. The carburetor regulates the fuel-air mixture for the engine's operation, ensuring it gets the right balance for combustion.

Fuel pumps are used in both petrol and diesel engines to supply fuel to the engine, but they don't mix the air and fuel. Injectors are used in diesel engines (and some modern petrol engines) for direct fuel injection.
