Can you explain how a car engine works?

A car engine is composed of many different parts, including the combustion chamber, fuel delivery system, air intake and exhaust systems, pistons, valves, crankshaft, and spark plug. The combustion chamber is where the fuel-air mixture is ignited by the spark plug, which causes the piston to move downwards, creating mechanical energy that is transferred through the connecting rods to the crankshaft. This rotation then creates power for the wheels and propels the car forward. The air intake and exhaust systems are responsible for providing oxygen and removing carbon dioxide from the combustion process. The pistons compress the fuel-air mixture in the combustion chamber before it is ignited, while the valves regulate the amount of air entering and leaving the combustion chamber. Finally, the spark plug provides the ignition source needed to initiate the combustion reaction.
