The term scavenging is generally associated with
A
2-stroke cycle engines
B
4-stroke cycle engines
C
Aeroplane engines
D
High efficiency engines
Correct Answer: High efficiency engines
The term scavenging is generally associated with High efficiency engines.In Automobiles, Scavenging is a process of pushing exhaust gas out of the cylinder and drawing in fresh draught of air or air fuel mixture for the next cycle. The process is essential in having a smooth running of I.C. Engine. If scavenging is incomplete the following stroke will begin with a mix of exhaust fumes rather than clean air. This may be insufficient for poor combustion which leading to poor running condition on an engine.Scavenging is equally important for both 2 Stroke and 4 Stroke Engine. However, it is more difficult to achieve in 2 Stroke engine.
