Generator is a kind of mechanical equipment which converts other forms of energy into electrical energy. It is widely used in industrial and agricultural production, national defense, science and technology and daily life. Generator diesel engine is one form of generator. We need to understand its characteristics in order to apply it better.

How does the generator engine works?

In the cylinder of a diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector. Under the upward extrusion of the piston, the volume is reduced and the temperature rises rapidly, reaching the ignition point of diesel. When the diesel oil is ignited, the gas mixture burns violently and the volume expands rapidly, pushing the piston downward, which is called "work". Each cylinder works in a certain order, and the thrust acting on the piston becomes the force to push the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate.

If the brushless synchronous alternator is installed with the crankshaft of the diesel engine, the rotation of the diesel engine can be used to drive the rotor of the generator. Using the principle of "electromagnetic induction", the generator will output the induced electromotive force, and the current can be generated through the closed load circuit.

What are the advantages and disadvantages of generator engines?

  • Advantages

(1)High thermal efficiency. That is, low fuel consumption and good economy

(2)Wide power range. The power of a single machine can range from zero to tens of thousands of kilowatts.

(3)It has the advantages of compact structure, light weight, small ratio of gas turbine mass to its rated power and easy to move.

(4)It can be started quickly and operated easily, and can reach full load operation soon after starting.

  • Disadvantages

(1)The demand for fuel is high. High speed gas engines generally use gasoline or light diesel as fuel, and require strict fuel cleanliness. It is difficult to use solid fuel or inferior fuel in cylinder section.

(2)Exhaust pollution and noise cause public hazards.

(3)The structure is complex and the machining precision of parts is high.

 

What are the applications of generator engines?

Generator diesel engine set is a kind of small power generation equipment, which uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. The whole set is generally composed of diesel engine, generator, control box, fuel tank, storage battery for starting and control, protection device, emergency cabinet, etc. The whole can be fixed on the foundation for positioning, and can also be installed on the trailer for mobile use. The generator diesel engine set is a non continuous operation power generation equipment. If it runs continuously for more than 12 hours, its output power will be lower than 90% of the rated power. Although the power of generator engine set is low, it is widely used in mines, railways, field construction sites, road traffic maintenance, factories, enterprises, hospitals and other departments as backup or temporary power supply because of its small size, flexibility, portability, complete supporting facilities and easy operation and maintenance.

 

As a kind of generator, the generator diesel engine is widely used in various fields. Only after a comprehensive understanding of its characteristics can we better choose according to the demand. If you want to know more about diesel generator, please contact us.
