A crankshaft converts the linear energy of the pistons into rotational energy in an engine. The rotational motion then transfers through the gearbox to the wheels.Know More
A crankshaft is also referred to as a crank and has four main parts, which are the main journals, the connecting rod journals, the piston assembly and a flywheel in some engines. Other parts include webs, pins, throws and rear main bearing journal.
The main journals are the most significant parts as they act as support points and the center of rotation for the crank. In most crankshaft assemblies, the main journals as well as the connecting rod journals have a hollow construction that helps boost the crank’s torque capability in addition to reducing the total weight of the assembly.
In manual transmission engines, the flywheel is the point at which the engine and the drive train connect. In automatic transmission engines, the connecting point is called a torque converter.
The crankshaft is set in motion when compressed air and fuel ignites, resulting in a powerful force that is exerted on top of the pistons. When the pistons move down into the cylinder, the connecting rods push against the crankshaft.
The crankshaft is designed to move in a rotary motion when the connecting rods apply force to it as opposed to the up and down motion of the pistons and connecting rods.Learn more about Car Parts & Maintenance
A car alternator is an aluminum piece of equipment attached to a car engine's crankshaft by a drive belt. When the crankshaft begins turning after the engine is ignited, it rotates the drive belt, which forces the alternator to rotate in response. The movement of the alternator generates magnetic power that is transferred to the car's battery to power lights, windows, locks, air conditioning, the dashboard and the radio.Full Answer >
Crankshaft sensors are located in the crank pulley, flywheel, camshaft or directly on the crankshaft. Crankshaft position sensors, which ensure that the vehicle starts and remains running, are one of the most important components of an engine.Full Answer >
The crank sensor is either located on the main crank pulley, the flywheel, the camshaft or on the crankshaft itself. The most common location is at the bottom of the engine block, where the crankshaft is.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 >
