Explain the working of a four-stroke engine.

Question

Accepted Answer

A four-stroke engine operates through four distinct phases: intake, compression, power, and exhaust, converting fuel into mechanical energy.

1. Intake Stroke: The intake valve opens, and the piston moves down, drawing in a fuel-air mixture.
2. Compression Stroke: The piston moves up, compressing the mixture, increasing temperature and pressure.
3. Power Stroke: The spark plug ignites the compressed mixture, forcing the piston down and producing power.
4. Exhaust Stroke: The exhaust valve opens, and the piston moves up again, expelling burnt gases from the cylinder.
