In the field of science and technology in the United States, there is an encyclopedia author who is famous for focusing on the field of calcium carbonate. She not only has profound background knowledge and experience accumulation in the field of chemistry, but also has won the love and respect of readers with her profound and simple question-and-answer method.
A car engine, specifically an internal combustion engine, works based on a four-stroke combustion cycle: intake, compression, combustion (power), and exhaust.
1. Intake: This is the phase where the intake valves open, and the piston moves down to allow the engine to take in a mixture of air and fuel.
2. Compression: In this phase, the piston moves back up and compresses the air-fuel mixture, making it highly combustible. The intake valves close to trap the air-fuel mixture inside.
3. Combustion (Power): This is the phase where the spark plug ignites the compressed air-fuel mixture, creating a mini explosion. The force of the explosion drives the piston back down, and this motion transfers through the crankshaft, eventually reaching the wheels.
4. Exhaust: After the combustion, the exhaust valves open up, and the piston moves up again to push out the waste gas produced during combustion, preparing the cylinder for the next intake of air and fuel.
This cycle repeats several thousand times per minute, and it's what drives your car and allows it to move. The engine is connected to other parts of the car system like the radiator (cools the engine), the exhaust system (removes waste gases), etc. which all ensure the smooth functioning and efficiency of the engine.
