What are the components and functions of the crank-connecting rod mechanism?
1 Answers
The components of the crank-connecting rod mechanism include: the engine block group, the piston-connecting rod group, and the crankshaft-flywheel group. The function of the crank-connecting rod mechanism is to provide a combustion chamber, convert the expansion pressure of the gas generated by fuel combustion acting on the top of the piston into the rotational torque of the crankshaft, and continuously output power. The engine block group consists of the cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner, and oil pan. The piston-connecting rod group consists of the piston, piston rings, piston pin, and connecting rod. The crankshaft-flywheel group consists of the crankshaft, flywheel, torsional damper, and balance shaft. The function of the crankshaft-flywheel group is to convert the gas force transmitted by the piston-connecting rod group into the rotational torque of the crankshaft for external output, driving the engine's valve train and other auxiliary devices to work.
