【Summary Description 】

The main components of a diesel engine generally include: body, crank and connecting rod mechanism, valve mechanism, fuel system, lubrication system, cooling system, and electrical system.

1. Body: It is the skeleton of the diesel engine, which supports and installs other parts, including: cylinder block, cylinder liner, cylinder head, cylinder head gasket, oil pan, flywheel housing, timing gear housing, front and rear feet.

2. Crank connecting rod mechanism: It is the main moving part of the diesel engine. It can convert the energy generated by fuel combustion into mechanical energy through pistons, piston pins, connecting rods, crankshafts, and flywheels. Including crankshaft, connecting rod, piston, piston pin, piston pin circlip, piston pin bushing, piston ring, main bearing, connecting rod bearing, thrust bearing, crankshaft front and rear oil seals, flywheel, shock absorber, etc.

3. Air distribution mechanism: the intake and exhaust valves are opened and closed regularly. Including timing gears, camshafts, lifters, ejector rods, rocker arms, valves, valve springs, valve seats, valve guides, valve lock blocks, intake and exhaust pipes, air filters, silencers, superchargers, etc.

4. Fuel supply system: According to the needs of the diesel engine, the diesel fuel is supplied to the combustion chamber for combustion regularly and quantitatively. Including diesel tanks, oil pipes, diesel filters, fuel injection pumps, fuel injectors, etc.

5. Lubrication system: It supplies lubricating oil to each motion friction pair, including oil pump, oil filter, pressure regulating valve, pipeline, instrument, oil cooler, etc.

6. Cooling system: dissipate the heat generated by the diesel engine to the atmosphere. Including water tank, water pump, fan, water pipe, thermostat, water filter, fan belt, water temperature meter, etc.

7. Electrical appliances: auxiliary equipment for starting, lighting, monitoring and operation. Including generators, starting motors, batteries, relays, switches, lines, etc.
