Diesel Engine Components

The main mechanical components of a diesel engine generally include: body, crank and connecting rod mechanism, valve train, fuel system, lubrication system, cooling system, and electrical system.
1. Body: It is the skeleton of the diesel engine, which supports and installs other components, including: cylinder block, cylinder liner, cylinder head, cylinder gasket, oil pan, flywheel housing, timing gear housing, and 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 the piston, piston pin, connecting rod, crankshaft, and flywheel. Including crankshaft, connecting rod, piston, piston pin, piston pin circlip, piston pin bushing, piston ring, main bearing bush, connecting rod bush, thrust bearing, crankshaft front and rear oil seals, flywheel, shock absorber, etc.
3. Valve distribution mechanism: It opens and closes the intake and exhaust valves regularly. Including timing gears, camshafts, tappets, push rods, rocker arms, valves, valve springs, valve seats, valve guides, valve lock blocks, intake and exhaust pipes, air filters, mufflers, superchargers, etc. .
4. Fuel supply system: according to the needs of the diesel engine, diesel is supplied to the combustion chamber regularly and quantitatively for combustion. Including diesel tank, fuel pipe, diesel filter, fuel injection pump, fuel injector, etc.
5. Lubrication system: supplies lubricating oil to various moving friction pairs, including oil pumps, oil filters, pressure regulating valves, pipelines, instruments, oil coolers, etc.
6. Cooling system: it dissipates 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, starter motors, batteries, relays, switches, wiring, etc.
