Question

With engines working on Otto cycle, a part of the mixture is lost as it escapes through the exhaust port during scavenging.

(a) True

(b) False

I had been asked this question in my homework.

My question is from Disadvantages of Two Stroke Engines in division Two Stroke Engines of IC Engine

Answer 1

Answer: (a) True

Explanation: In engines working on the Otto cycle, especially in two-stroke engines, some of the air-fuel mixture is lost during the scavenging process. The scavenging process occurs when the exhaust gases are expelled, and the fresh air-fuel mixture enters the combustion chamber. Due to the design of two-stroke engines, some of the mixture can escape through the exhaust port, leading to inefficiencies and loss of fuel. This contributes to higher fuel consumption and lower overall efficiency in comparison to four-stroke engines.
