Major Parts of Diesel Generator sets and it’s working principle

Diesel Genset is a combination set, where a diesel engine runs an Alternator. People also know Alternator as generator. Diesel Engine function is to rotate the alternator. Engine get energy from diesel.

People generally use diesel generator sets in Industries as an emergency power-supply. And it can be a backup power supply if the grid fails.

While it is rotating, alternator generates the power. Engine is tool to rotate alternator.

Diesel Engine Working Proncuple in Cycle

Four cycle are commonly seen in Diesel Engine. They are: Intake, Compression, Combustion and finally Exhaust.

Diesel Genset works exactly according to the Energy conversion law. We all know that we cannot create energy. We can only convert energy into other forms of energy.

Initially Diesel have chemical energy but during combustion process chemical energy converted into heat, heat converted to force. Finally, force works as a mechanical energy that rotate the Alternator.

Then alternator converts the mechanical energy into Electrical Energy. Some energy losses as heat in the process which goes to atmosphere by the help of radiator.

We know that Radiator is a cooling system. Modern diesel engine able to convert energy with high efficiency up to 45%. That means 55% of energy losses as heat.

From the above discussion we can divide Genset mainly into three parts. They are 1. Alternator 2. Engine and 3. Radiator. There are other sub parts or helping spare parts of that main three parts. Most common sub parts are Exhaust, water separator, turbo charger, fuel filter, lube oil filter, control panel, air filter, battery, battery charger, After cooler, breather filter, starter motor, oil chamber and few others spare parts.
