discuss stages of combustion

There are generally four stages of combustion in a fuel-powered engine:

1. Induction: The first stage of combustion involves the intake of air and fuel into the engine. The air is drawn in through the intake manifold, while the fuel is injected into the combustion chamber. The air-fuel mixture needs to be carefully balanced to ensure efficient combustion.

2. Compression: In the compression stage, the piston moves upward in the combustion chamber, compressing the air-fuel mixture. This compression increases the pressure and temperature of the mixture, preparing it for ignition.

3. Ignition: The ignition stage is where the spark plug in the engine ignites the compressed air-fuel mixture. This ignition causes the mixture to combust, rapidly expanding and creating a powerful force that pushes the piston back down in the combustion chamber.

4. Exhaust: The final stage of combustion is the exhaust stage, where the burned gases are expelled from the engine. The exhaust valve opens, allowing the burned gases to exit the combustion chamber and flow out through the exhaust system, releasing energy and emissions.
