Four stroke engine?
A four-stroke engine, also known as a four-cycle engine, is a type of internal combustion engine that completes a power cycle in four distinct strokes of the piston within the cylinder. The four strokes are intake, compression, combustion, and exhaust. Here's a brief overview of each stroke: 1. Intake Stroke: The piston moves downward, creating a partial vacuum in the cylinder. The intake valve opens, allowing a mixture of air and fuel to enter the combustion chamber from the intake manifold. 2. Compression Stroke: The piston moves upward, compressing the air-fuel mixture. Both the intake and exhaust valves remain closed during this stroke. 3. Combustion Stroke (Power Stroke): When the piston reaches the top of the compression stroke, the compressed air-fuel mixture is ignited by a spark plug. The rapid combustion of the mixture creates a high-pressure gas that forces the piston back down with significant force. This downward motion is what generates power in the engine...
