Explanation
In the crankcase scavenging method, the air pressure necessary for scavenging is created by the movement of the engine piston, which compresses the air in the crankcase. Other devices like superchargers, centrifugal pumps, natural aspirators, and reciprocating pumps are not involved in generating this pressure in this specific method.
