What powers the crankshaft? | AnswersDrive

Power cycle: spark from a spark plug ignites the fuel-air mix. The explosion forces the piston down the cylinder. As the pistons are forced up and down they rotate the crankshaft, which after sending the power through the transmission, turns wheels. Most cars have at least four cylinders.

Just so, what is a crank shaft?

Crankshaft converts reciprocating motion to rotational motion. It is how you get your car to move. If you know how an engine operates, the piston reciprocates as fuel burns and the gases are emitted. The piston is connected to the crankshaft via a connecting rod.

What is the function of a crankshaft in a car?

The function of the crankshaft is to translate the linear reciprocating motion of a pistons into the rotational motion required by the automobile. This is accomplished by connecting the pistons to the crank throws, which are offset from the central axis of the crankshaft to create a rotation about that axis.
