At the end of the expansion stroke, the combustion chamber of a two-stroke engine is left full of combustion product. This is because, unlike four-stroke engine there is no exhaust stroke available to clear the cylinder of burnt gases.
The process of clearing the cylinder, after the expansion stroke is called scavenging process.

Scavenging in an I.C. Engine
- Definition: Scavenging in an internal combustion engine refers to the process of removing the burnt gases from the combustion chamber of the engine cylinder.
- Importance: Efficient scavenging is crucial for the engine performance as it ensures that the fresh air-fuel mixture can enter the combustion chamber without any hindrance.
- Process: During the scavenging process, the exhaust gases from the previous cycle are expelled through the exhaust valve while fresh air enters through the intake valve to prepare for the next combustion cycle.
- Types: There are two main types of scavenging - uniflow scavenging and loop scavenging. Uniflow scavenging involves a one-way flow of air through the cylinder, while loop scavenging involves a two-way flow of air through the cylinder.
- Benefits: Proper scavenging helps in improving engine efficiency, reducing emissions, and enhancing overall performance.
By understanding the concept of scavenging in an internal combustion engine, engineers can optimize the design and operation of the engine to achieve better performance and efficiency.
