What are the main components of the crank connecting rod mechanism?

The main components of the crank connecting rod mechanism are: the engine block group, the piston connecting rod group, and the crankshaft flywheel group. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, while converting the force acting on the piston into the torque output by the crankshaft to drive the rotation of the car wheels. The differences between the engine block group, the piston connecting rod group, and the crankshaft flywheel group are: 1. The engine block group consists of: the cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner, and oil pan. 2. The piston connecting rod group consists of: the piston, piston rings, piston pin, and connecting rod. 3. The crankshaft flywheel group consists of: the crankshaft, flywheel, torsional damper, and balance shaft.
I've been tinkering with engines for over a decade. The crank-connecting rod mechanism, simply put, is the core component that converts piston motion into wheel rotation. It mainly consists of three major parts: the engine block group including basic frameworks like cylinder block and cylinder head; the piston-connecting rod group with piston, piston rings, piston pin and connecting rod; finally the crankshaft-flywheel group where the crankshaft connects to the connecting rod to transform reciprocating motion into rotation, while the flywheel ensures smoother rotation. What we fear most is piston ring wear causing oil burning, or excessive crankshaft clearance making the engine shake. Every major overhaul requires precise micrometer measurements of these components.
