Diesel Generator and its Major Components

What is a diesel generator?

A diesel generator is made up of a diesel engine and an alternator to convert mechanical energy into electrical energy. Diesel generator sets are widely used in places without connection to the power grid and for emergency power supply.

Major components of a diesel generator

The major components of a diesel generator can be classified as follows:

  1. Diesel Engine: The source of mechanical energy input for generators. Its size and output capacity determine how much power a unit can generate.
  2. Alternator: Produces electrical energy from the mechanical input supplied by the diesel engine.
  3. Radiator & Cooling System: As using the generator continually heats up various components, the cooling system helps withdraw heat produced when the generator is working.
  4. Exhaust System: Exhaust fumes emitted by a diesel generator contain highly toxic chemicals that need to be properly managed.
  5. Air Filter: The filter is composed of fibrous materials, which removes solid particles such as dust, pollen, mold and bacteria from the air.
  6. Control Panel: The user interface controls the generator, including start up and shut down controls, fuel gauges, phase selector switches etc.
  7. Base Frame & Fuel Tank: The base frame provides a structural base support. The fuel tank stores fuel to be used by the generator, and it usually has an adequate capacity to keep the generator to run for 6-8 hours on an average.
