Full Answer

Most car engines burn fuel in four-stroke combustion cycles, which involve intake, compression, combustion and exhaust of fuel and air. The car engine takes in a mixture of fuel and air, compresses it and ignites it to produce high-temperature, high-pressure gases. These gases apply force to the piston, causing it to move linearly and open the exhaust valve, releasing the exhaust. The crankshaft then converts the piston’s linear motion into rotational motion, which is then used to turn the wheels.

  • Q:

    How does a car move?

    A:

    A car powered by an internal combustion engine moves by transmitting the engine's rotational movement to the wheels via the transmission, driveshaft and differential. Front-wheel drive cars do not require a driveshaft, but rear-wheel drive and four-wheel drive cars use driveshafts to transmit power to the rear wheels.
