Diesel generators are complex systems consisting of different essential parts including engines, fuel systems, and control panels with each of them performing distincts tasks. So it is understandable if you find it hard to comprehend their components. Here is a simple guide to the various parts, components and systems that make up your generator.

Starting with the basics, the engine is the powerhouse of the generator, therefore maintaining its health is paramount. It is responsible for converting fuel into mechanical energy. The size of your generator’s engine is inherently equal to its maximum energy power output, this makes it important to keep the engine’s capacity in mind while loading.

The result of this study concluded that Proper sizing and specification of diesel generators engines are important, it also stated that in the nearest future computer modeling may be used to predict their response to dynamic loads. Cool right?

The alternator comes right after the engine. The alternator is responsible for converting mechanical energy into electricity. This part houses two major components which help in the effective production of energy and they are known as the stator which contains a set of electrical conductors and the rotor which produces a magnetic force causing electrons to move and produce electricity. According to Saputro in 2017, the engine rotates the rotor, creating a magnetic field that interacts with the rotor to generate electricity according to Lorentz’s law.


Fuel systems are also integral, before your generator can function you must provide it with a fuel source which is converted to energy and then electrical outputs. The size of your fuel tank usually determines the capability of your generator in terms of duration. Any malfunction in these parts can lead to inefficiencies or even engine failure, making their maintenance non-negotiable.

Control panels are a set of components that display the details and parameters of the diesel generator including the voltage, current and frequency. They allow the generator to monitor itself and then manage any operation that might be irregular. It is also an opportunity for you to properly monitor your system’s diagnostics and operations.

Other essential spare parts include the cooling and exhaust system components like radiators, lubrication systems and water pumps, which prevent the generator from overheating.

The reliability of a diesel generator heavily depends on the availability and quality of its spare parts. This is where JubailiBros.com saves the day, we provide the best diesel diesel generators with high quality spare parts.
