The crankshaft is one of the most important components in a car engine that can play a fundamental role in the car's movement mechanism. Given that all the important components of a car engine are interconnected, problems and defects in each can cause damage and failure to other parts. The car's engine is made up of various parts. Disruption in their functioning causes problems and the car's inability to move. One of the most important parts that plays a fundamental role in moving the car is the crankshaft. By converting the piston movement from linear to rotational, this part can help the engine to obtain the required force to move.

Another task assigned to the crankshaft is to transfer rotational force to the flywheel located at its end. This part can transfer rotational motion to the valve stem through the timing belt. By examining the functions of this part further, we realize that it can also transfer motion to the generator or alternator

Installing a gear at the front of the crankshaft allows other parts to be driven. In addition, a part is installed at its end that will be a place for the flywheel. By examining the operation and functions of this part of the car engine, we realize that in order to drive the connecting rod, it is necessary to show its applications. In addition, by converting the linear motion of the piston into rotational motion, it will provide the required force.
