Principle of Cummins Generator Set Driving Generator

Feb. 06, 2023

Today, we will briefly introduce the principle of Cummins generator set driving generator.


cummins diesel generator


In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel injected by the fuel injector. Under the upward extrusion of the piston, the volume decreases and the temperature rises rapidly, reaching the ignition point of the diesel fuel. The diesel fuel is ignited, the mixed gas burns violently, the volume expands rapidly, and pushes the piston downward, which is called "work". Each cylinder works in a certain order, and the thrust acting on the piston turns into the force pushing the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate. When the brushless synchronous alternator and the crankshaft of the diesel engine are installed coaxially, the rotation of the diesel engine can be used to drive the rotor of the generator. By using the principle of 'electromagnetic induction', the generator will output the induced electromotive force and generate current through the closed load circuit. Only the basic working principle of Cummins generator set is described here. In order to obtain usable and stable power output, a series of diesel engine and generator control and protection devices and circuits are also required.


Cummins generator set is an independent power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control box, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components. The whole can be fixed on the foundation for positioning and can also be installed on the trailer for mobile use. Cummins generator unit is a non-continuous operation power generation equipment. If the continuous operation exceeds 12h, its output power will be about 90% lower than the rated power. Although the power of Cummins generator set is low, it is widely used in mines, railways, field construction sites, road traffic maintenance, factories, enterprises, hospitals and other departments as standby or temporary power supply because of its small size, flexibility, portability, complete supporting facilities and easy operation and maintenance. At the same time, this small Cummins generator set can also be used as a small mobile power station and become a backup power supply for many enterprises.
