What are the components and functions of the crank-connecting rod mechanism?

[SanRowan]

The function of the crank-connecting rod mechanism is to provide a combustion chamber, convert the expansion pressure of the gas acting on the top of the piston after fuel combustion into the rotational torque of the crankshaft, and continuously output power. The following are the components of the crank-connecting rod mechanism: 1. Engine block group: cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner, and oil pan; 2. Piston-connecting rod group: piston, piston ring, piston pin, connecting rod; 3. Crankshaft-flywheel group: crankshaft, flywheel, torsional vibration damper, balance shaft. The following are its functions: 1. Convert gas pressure into crankshaft torque; 2. Convert the reciprocating motion of the piston into the rotational motion of the crankshaft; 3. Convert the force of combustion acting on the top of the piston into crankshaft torque to output mechanical energy to the working machinery.
