What is the composition of the crankshaft flywheel assembly?
1 Answers
The crankshaft flywheel assembly consists of the crankshaft, crankshaft pulley, crankshaft torsional vibration damper, crankshaft main bearings, flywheel, starter ring gear, and other components. Below are the related introductions: 1. Function of the crankshaft: It converts the force transmitted from the connecting rod into rotational torque, which is then transmitted to the clutch via the flywheel, while simultaneously driving components such as the water pump, generator, and camshaft. The crankshaft is composed of main journals, connecting rod journals, crankshaft arms, counterweights, the crankshaft front end, and the crankshaft rear end. 2. Function of the flywheel: It stores the energy from the power stroke to provide power during non-power strokes and ensures smooth rotation of the crankshaft to reduce vibration. The flywheel also facilitates engine starting via the starter motor through 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 top dead center (TDC) and ignition timing marks. 3. Engine firing order: In a four-stroke multi-cylinder engine, the crankshaft completes two full rotations for each cylinder to perform one power stroke.
