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.Know More
Each crankshaft is designed for a specific engine. Using the example of a four-stroke engine, the crankshaft has four crank throws for connecting the four pistons and is generally connected to the flywheel. During the combustion cycle of the engine, these crank throws act as a lever arm for the piston to push, thereby creating rotational motion. 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.
In addition to the crank throws, the crankshaft is also comprised of carefully designed weights and balances to reduce engine vibration. Either end of the crankshaft is connected to the engine block by the crank bearings. To smooth out the power delivery of the engine between the combustion cycles of the pistons, a fly wheel is also incorporated onto the crankshaft.Learn more about Car Parts & Maintenance
A boxer engine is a four-stroke engine that has its pistons move simultaneously toward and away from one another on a horizontal plane. Each pair of pistons that lie next to each other has a motion that resembles a boxer throwing his fists, hence the name of the engine.Full Answer >
A crankshaft is a component in car engines that converts linear motion into rotary motion. Through a series of connected components, this motion then moves the vehicle’s wheels so that the vehicle can move forward.Full Answer >
The crankshaft position sensor is an electrical component in vehicles that tells the system's onboard computer where the crankshaft is currently located. This information allows the system to adjust fuel flow to individual pistons and ensure smooth rotation, even at higher RPMs.Full Answer >
A crank sensor is an electronic device on most automobiles that detects engine speed by monitoring the rotation of the crankshaft. Most newer vehicles us a crank sensor in conjunction with camshaft position sensor to provide data that the automobile's computer uses to coordinate the engine ignition sequence.Full Answer >
