How does combustion occur in a gas engine of a car?
Combustion occurs in a gas engine of a car through the following process:
1. Intake stroke: A mixture of air and fuel (gasoline) is drawn into the cylinder through an intake valve.
2. Compression stroke: The piston moves back up, compressing the mixture of air and fuel.
3. Ignition: A spark plug fires, igniting the fuel-air mixture, which rapidly burns, creating high-pressure gases.
4. Power stroke: The high-pressure gases push the piston downward, which turns the crankshaft, generating power that propels the car.
5. Exhaust stroke: The piston moves back up, pushing the exhaust gases out through an exhaust valve.
6. Repeat: The process repeats for each cylinder in the engine, with the engine's control system adjusting the timing and duration of each step to optimize performance.
Combustion in a gas engine occurs through the following steps:
1. Intake Stroke: The intake valve opens, and the piston moves downward, drawing a mixture of air and fuel into the combustion chamber.
2. Compression Stroke: The piston moves back up, compressing the air-fuel mixture. This compression raises the temperature and pressure in the combustion chamber.
3. Ignition: At the top of the compression stroke, a spark plug ignites the compressed air-fuel mixture. The spark plug creates an electric spark that ignites the fuel vapor.
4. Power Stroke: The ignited fuel rapidly expands, generating a high-pressure combustion gases. The pressure pushes the piston downward, converting the expanding gas energy into mechanical energy.
5. Exhaust Stroke: The exhaust valve opens, and the piston moves back up, pushing the exhaust gases out through the exhaust manifold and into the exhaust system.
6. Repeat: The engine repeats the four-stroke cycle (intake, compression, ignition, and exhaust) thousands of times per minute to generate continuous power.
