How does burning gasoline make a car move?

Answer 1

There are four steps to the cycle of a car's engine. These steps involve the combustion, or burning, of gasoline as a force that drives the procedure, and therefore moves the car. (1) Intake: The cyllinder of the engine has a piston that can move up and down, much like pushing a cotton ball up a straw. The intake stage occurs when the piston moves down the shaft. The vacuum created by the falling piston pulls gas and air into the space. (2) Compression: As more of the air/gas mixture enters the shaft of the piston, pressure increases. (3) Power/ Ignition: Eventually, the pressure reaches a critical point where the gas/ air mixture ignites, forcing the piston up and moving the car. (4) Exhaust: After the explosion, the exhaust (smoke) is released from the piston as it moves back to the rest position and begins to take in more gas and air.
