What Does the Four-Matching Set of a Diesel Engine Include?

[EloiseAnn]

The four-matching set of a diesel engine includes the cylinder liner, piston, piston rings, and piston pin. The main structural components of a diesel engine generally consist of the engine block, crankshaft-connecting rod mechanism, valve train, fuel system, lubrication system, cooling system, and electrical system. The detailed introduction of the four-matching set of a diesel engine is as follows: Engine Block: It serves as the framework of the diesel engine, supporting and mounting other components, including the cylinder block, cylinder liner, cylinder head, cylinder gasket, oil pan, flywheel housing, timing gear housing, and front and rear mounts. Crankshaft-Connecting Rod Mechanism: This is the primary moving part of the diesel engine, converting the energy generated by fuel combustion into mechanical energy through the piston, piston pin, connecting rod, crankshaft, and flywheel. It includes the crankshaft, connecting rod, piston, piston pin, piston pin circlip, piston pin bushing, piston rings, main bearing shells, connecting rod bearing shells, thrust bearing, front and rear crankshaft oil seals, flywheel, and vibration damper. Valve Train: It controls the timing of opening and closing the intake and exhaust valves, including the timing gear, camshaft, tappet, pushrod, rocker arm, valve, valve spring, valve seat, valve guide, valve lock, intake and exhaust pipes, air filter, muffler, and turbocharger. Fuel Supply System: It supplies diesel to the combustion chamber in a timely and measured manner according to the needs of the diesel engine, including the fuel tank, fuel line, diesel filter, fuel injection pump, and fuel injector. Lubrication System: It supplies lubricating oil to various moving friction pairs, including the oil pump, oil filter, pressure regulator valve, pipelines, gauges, and oil cooler. Cooling System: It dissipates the heat generated during the operation of the diesel engine to the atmosphere, including the radiator, water pump, fan, water pipe, thermostat, water filter, fan belt, and water temperature gauge. Electrical System: It consists of auxiliary equipment for starting, lighting, monitoring, and operation, including the generator, starter motor, battery, relay, switch, and wiring.
