Question

(a) Air filter cools down the air

(b) Air filter changes direction of air flow

(c) Air filter removes dust from air

(d) Air filter helps in flow of fuel

The question was posed to me in an online quiz.

The query is from Components of a Diesel Engine Plants topic in chapter Diesel Engine Plant of Energy Engineering

Answer 1

Correct answer is (c) Air filter removes dust from air

The best explanation: Air filter removes the dust from air before entering the engine. Air actually contains oxygen which supports the combustion inside the engine chamber. And also helps in moving/taking out the exhaust fumes which are produced after combustion.
