Components and Systems of Diesel Generator Set

A diesel generator set consists of three main parts: diesel engine, generator, control system, and other accessories. In short, the working process of a diesel generator set is that the diesel engine drives the generator to run for power generation, consuming diesel oil and converting it into electric current. The power of the matched engine is slightly greater than or equal to that of the generator.

Cummins Diesel Engine Components

The basic components of a Cummins diesel engine include: crankshaft connecting rod mechanism, valve train, transmission mechanism, fuel supply system, lubrication system, cooling system, starting system, and intake and exhaust systems.

Fuel System

Main components: fuel injection pump, fuel injector, oil pipe, fuel filter, fuel transfer pump, hand pump, etc. After continuous research and technical refinement, the fuel system of generator sets has developed from in-line pump fuel injection system to modern electronic control fuel injection systems, such as electronic control unit pump system and electronic control distributor pump system.

Valve Train

Mainly includes camshaft, tappet, push rod, valve, rocker arm, valve spring, etc.

Starting System

Mainly includes starter, battery, starting switch, wires, etc.

Cooling System

The function of the cooling system is to transfer part of the heat from the heated parts to keep the parts at a normal working temperature. It includes cooling fan, water tank, water pump, water pipe, thermostat, fluid replacement tank and coolant, etc.

Crankshaft Connecting Rod Mechanism

Includes: engine block, cylinder head, cylinder liner, piston, connecting rod, crankshaft, flywheel, piston ring, oil pan, bearing bush, etc.

Lubrication System

Includes oil pump, oil filter, oil radiator, oil pipe, main oil gallery and oil, etc. The functions of the lubrication system are to improve mechanical efficiency; reduceparts wear and tear, prolong service life, take away part of the heat of parts, cool the temperature of parts, take away metal chips and other dirt caused byparts wear and tear, and prevent the part surface from oxidation and corrosion due to contact with water, air and gas.

Intake and Exhaust Systems

Includes intake pipe, turbocharger, air filter, exhaust pipe, muffler, etc.

The crankshaft connecting rod mechanism, valve train, transmission mechanism, fuel supply system, lubrication system, cooling system, starting system, and intake and exhaust systems constitute the diesel engine. They cooperate with each other and are indispensable. Any failure in any of these systems will cause the diesel generator set to fail to work normally, affecting production income and causing economic losses. Dingbo Power Generator reminds users to pay attention to the immediate maintenance of the generator, and especially pay attention to regular maintenance. Do not use unqualified diesel oil, engine oil or other accessories.
