There is no device that keeps the crankshaft rotation, the internal explosion that happens when the spark plug ignites the air/fuel mixture. I think you are refering to the flywheel.
That would be a flywheel. It stores rotational energy and smooths out fluctuations in speed to maintain stability in the device.
The device is known as a "motor".
The tachometer is an electrical device that senses the ignition system. It indicates engine RPM (revolutions per minute). Engine rpm and crankshaft rpm are two ways of expressing the same thing. True, the crankshaft does rotate twice for each complete set of cylinder firings but the tachometer counts each rotation.
Crankshaft position sensor function is to monitor the position or rotational speed of the crankshaft. It is an electronic device and it is used in the internal combustion engine.
A flywheel is a device that stores mechanical energy by spinning continuously and maintaining rotational motion even after the input energy has stopped.
A sundial is a device that tracks the movement of the sun by casting a shadow that moves as the Earth rotates.
A crankshaft is a device commonly used to convert linear motion into circular motion. As the crankshaft rotates, it causes pistons in an engine to move up and down in a linear fashion. Another device that achieves this conversion is a camshaft, which uses lobes to push against other components to create circular motion from a linear input.
A flywheel is a rotating mechanical device that stores energy by spinning. It helps to stabilize and regulate the speed of a machine by storing and releasing energy as needed. In mechanical systems, a flywheel can smooth out fluctuations in power and provide momentum for continuous operation.
A wheel is a round device that is fitted with a tire. The wheel rotates on the hub attached to the axle.
A wheel is a round device to roll a vehicle on. The wheel rotates around the axle which is fixed to the vehicle.
No, the wheel on a car is not a sphere. It is a circular device that is attached to the axle of the car and rotates to move the vehicle.
