Question

The efficiency of a two stroke engine does not depend on the effectiveness of the scavenging process.

(a) True

(b) False

I had been asked this question in homework.

My question is from Scavenging Process in section Two Stroke Engines of IC Engine

Answer 1

Answer: (b) False

Explanation: The efficiency of a two-stroke engine heavily depends on the effectiveness of the scavenging process. Effective scavenging ensures that exhaust gases are properly expelled and replaced with fresh charge, enabling better combustion and higher efficiency. Poor scavenging leads to residual exhaust gases, incomplete combustion, and increased fuel consumption, all of which reduce engine efficiency.
