It has 2 purposes. 1- to turn the engine over when first starting so the combustion process can begin. 2- most important it transfers the piston movement from up and down lateral motion to radial turning, providing mechanical energy to do many tasks. The most common is driving the transmission of an auto, but it is also used in power stations to turn generators. In large ships, it turns the propellers.
Crankshaft is used to change linear motion into rotational or circular motion. inother words it is used to change the pull or the push into rolling.
The crankshaft converts the linear motion of the piston into rotation of the crankshaft.
A crankshaft converts reciprocating motion into rotational motion.
To drive the belts
it is used to move the axel
The purpose of the crankshaft is to change vertical motion into horizontal motion.
it connects the piston to the crankshaft
The purpose of a connection rod is to provide fluid movement between pistons and a crankshaft.
spark to ign through the computer
lubricates the crankshaft and pistons
To covert linear motion (pistons) into radial motion (flywheel)
The crankshaft is an internal component of the engine that converts an up and down movement of the pistons to a rotational movement of the the crankshaft. This is provided to the powertrain for movement. The bottom of the pistons are attached to the crankshaft with main bearings.
it conects the crankshaft to the trans- as well as the starter uses it to crank the motor
