What are the five events of a four-stroke cycle engine in the correct order?

The five events of a four-stroke cycle engine are intake, compression, ignition, power, and exhaust, which is why the chosen answer is correct.

In a four-stroke cycle engine, the process begins with the intake stroke, where the intake valve opens, and the air-fuel mixture is drawn into the combustion chamber as the piston moves down. This is followed by the compression stroke, during which the intake valve closes, and the piston moves back up, compressing the air-fuel mixture.

The ignition event occurs when the spark plug fires, igniting the compressed mixture, which results in the power stroke. In this stroke, the explosion forces the piston down, converting the chemical energy of the fuel into mechanical energy. Finally, the exhaust stroke takes place, where the exhaust valve opens, and the piston moves back up to expel the combustion gases from the cylinder, preparing the engine for the next intake stroke.

Understanding the sequence of these events is essential for grasping how a four-stroke engine operates and helps in diagnosing issues related to engine performance and efficiency.
