Is it true that during the intake stroke, the burnt air-fuel mixture is forced out of the engine?

During the intake stroke of an engine, the primary action taking place is the drawing in of the air-fuel mixture into the cylinder. This occurs as the piston moves down, creating a vacuum that allows atmospheric pressure to push the new mixture into the combustion chamber.

In contrast, the burnt gases from the previous combustion cycle are expelled during the exhaust stroke, not the intake stroke. The timing and processes of these strokes are integral to the four-stroke cycle of an internal combustion engine.

The option noting that this statement is false is accurate, as it correctly distinguishes between the functions of the intake and exhaust cycles. Therefore, understanding the strokes of an engine and their respective roles is crucial for grasping how an engine operates efficiently.
