So, The function of crankshafts is to; translate the linear reciprocating motion of a piston into the rotational motion. Consequently, which are offset from the central axis of the crankshaft to create a rotation about that axis.
So, Using the example of a four-stroke engine; the crankshaft has four crank throws for connecting the four pistons. During the combustion cycle of the engine; these crank throws act as a lever arm for the piston to push. This is similar to pushing on the end of a wrench when turning a bolt. When the crankshaft completes its rotation; the crank throw will return the piston to the top of its cylinder.
The rear end of the crankshaft extends; outside the engine block and ends with a flywheel flange. Consequently, The flywheels heavy mass helps smooth the pulsation of the pistons firing at different times. Through the flywheel; the rotation makes its way; through the transmission and final drive; to the wheels. All this is in the bottom end of the engine. Finally, The ring gear carries the torque converter; passing drive into the automatic transmission.
As a result, The front end of the crankshaft; sometimes called the nose; is a shaft which extends beyond the crankcase. This shaft will be locked to a toothed gear; which drives the valve train through a timing belt or chain. Finally, A pulley which provides power through a drive belt; to accessories such as the alternator and water pump.
