What are the two major structures of an engine?

What are the two major structures of an engine?

Answer:

1. crank connecting rod crank connecting rod mechanism includes piston, connecting rod and crank with flywheel. This is the mechanism whereby the engine generates power and turns the reciprocating linear motion of the piston into the rotational motion of the crankshaft. In structural analysis, the body block and the crank link mechanism are often combined together. 2. the valve train includes the intake valve, the exhaust valve, the tappet, the intake camshaft, the exhaust camshaft and the camshaft timing belt (driven by the crankshaft timing gear). The function of the valve train is to charge the combustible gas into the cylinder in time and exhaust the exhausted gas from the cylinder in time.
Crank organism set the piston connecting rod group crankshaft and flywheel group block group by cylinder cylinder head gasket oil sump piston by the piston piston pin piston connecting rod bearing ring crankshaft flywheel group by crankshaft flywheel torsion damper on the back of the book
The gas distribution mechanism and crank linkage valve mechanism comprises a valve group and valve driving group. The valve group was divided into the valve exhaust valve valve spring valve spring valve lock valve transmission group by hydraulic tappet cam rocker rocker shaft
Engine: 2 big engines of engine, 5 main systems: crank connecting rod mechanism; valve mechanism; fuel supply system; cooling system; lubrication system; ignition system; starting system
