How Do Diesel Generators Work?

If you are not familiar with diesel generators, then you may be wondering what exactly they are and how they work. Well, diesel generators are very useful pieces of equipment designed to provide power in situations such as power outages.

Available in different physical and electrical configurations, portable diesel generators are a combination of a diesel engine and a generator and are commonly used as an auxiliary power source for industrial and residential units.

How do diesel generators work?

A diesel generator is actually a machine that converts mechanical energy (generated by a built-in internal combustion engine) into electrical energy. The different components of a diesel generator work in tandem to produce electricity. Some of the basic components of a powered diesel generator include

Engine - As the main component of a diesel generator set, the engine provides mechanical energy, which is subsequently converted into electrical energy. In fact, the output power of these diesel generators is directly proportional to the size of their engines.

Alternator - This is another key component of a diesel generator that uses the mechanical input provided by the engine and converts it into an electrical output. The alternator consists of a rotor that generates a magnetic field to eventually produce some alternating current. This is why the rotor is called the main part of the alternator.

Fuel system - This component stores and supplies fuel to the alternator. In general, a fuel system can easily run a 62.5KVA silent generator for about 6 to 8 hours.

Lubrication System - This unit ensures the smooth operation of the different components of the diesel generator. This is why it is recommended to have the generator's lubrication system properly checked to avoid any malfunction.

Control panel - The unit includes not only start/stop buttons, but also indicators for various parameters such as current, voltage and frequency. You can easily operate your 2.5KVA portable generator through its control panel.

Diesel generator working principle

In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the atomized diesel fuel injected through the nozzle at high pressure. When the piston works upward, squeezing is produced, the volume decreases, the temperature rises rapidly, and finally diesel ignition is achieved.

The diesel fuel is ignited and the mixture burns, expanding rapidly in volume and pushing the piston downward. Each cylinder works in sequence, and the thrust on the piston through the connecting rod becomes the power to push the crankshaft to rotate, thus driving the crankshaft to rotate.

Diesel generators use the principle of "electromagnetic induction", the generator output induction electric potential, and finally by closing the load circuit, you can generate electricity.
