What Components Make Up the Crankshaft Flywheel?

[VonCody]

The crankshaft flywheel is primarily composed of the crankshaft, flywheel, crankshaft pulley, and timing sprocket. Below is a detailed introduction: 1. Function of the crankshaft: It converts the force transmitted by the connecting rod into rotational torque, which is then transferred to the clutch via the flywheel, while also driving components such as the water pump, generator, and camshaft. 2. Function of the flywheel: It stores the energy from the power stroke to provide power for non-power strokes and ensures smooth rotation of the crankshaft, thereby reducing vibrations. The flywheel also facilitates engine startup through the starter engaging with its ring gear. Additionally, it serves as the driving disc of the clutch, transmitting the engine's power to the transmission system. The flywheel features markings for top dead center and ignition timing. 3. Engine firing order: In a four-stroke multi-cylinder engine, each cylinder fires once every two rotations of the crankshaft. Most domestic four-cylinder engines in passenger cars follow a firing order of 1-3-4-2, with a very few using the sequence 1-2-4-3.
