Can you explain how a car engine works?

A car engine is an internal combustion engine that converts the chemical energy of gasoline into mechanical energy to power the vehicle. The process begins when air and fuel are mixed in the intake manifold, which then enters the cylinders where they are compressed by the piston rings. As the mixture combusts, it creates a high-pressure gas that pushes the piston down, causing the crankshaft to rotate. This rotation causes the connecting rods to move up and down, transferring the energy produced from the combustion process to the drive shaft. Finally, the gears in the transmission convert this rotational energy into forward motion.
