The Four-Stroke Combustion Cycle

The four-stroke combustion cycle is a fundamental process that powers a car engine. It consists of four strokes: intake, compression, combustion, and exhaust. Each stroke contributes to the overall functioning of the engine by performing specific actions at different stages.

During the intake stroke, the piston moves downward, creating a vacuum that draws the air and fuel mixture into the cylinder. This mixture is crucial for the combustion process and the subsequent power generation. The compression stroke follows, where the piston moves upward to compress the air and fuel mixture, maximizing its potential energy.

The combustion stroke is the most critical stage of the cycle. It occurs when the spark plug ignites the compressed mixture, causing a controlled explosion. This explosion forces the piston back down, generating significant power that drives the engine’s motion. Finally, the exhaust stroke pushes out the burned gases through the exhaust valve, preparing the cylinder for the next intake stroke.

The Four-Stroke Combustion Cycle

• Intake Stroke: Piston Moves Downward – Air and fuel mixture is drawn into the cylinder.
• Compression Stroke: Piston Moves Upward – Mixture is compressed for maximum energy potential.
• Combustion Stroke: Ignition Occurs – Mixture is ignited, creating an explosion that powers the engine.
• Exhaust Stroke: Piston Pushes Out Gases – Burned gases are expelled through the exhaust valve.

The four-stroke combustion cycle is a continuous process that repeats itself to produce the necessary energy to power the vehicle. By understanding this cycle and the function of each stroke, car owners can gain a deeper knowledge of their engines and effectively address any performance issues that may arise.
