Working schematic diagram of generator

1, principle of diesel generator: the diesel engine drives the generator to run and converts the energy of diesel into electric energy.

In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel oil sprayed by the fuel nozzle. Under the upward extrusion of the piston, the volume decreases and the temperature rises rapidly, reaching the ignition point of diesel oil. The diesel oil is ignited, the mixture burns violently, and the volume expands rapidly, pushing the piston downward, which is called' doing work'.

2. Gasoline generator: The gasoline engine drives the generator to run and converts the energy of gasoline into electric energy.

In the cylinder of gasoline engine, the mixture burns violently and the volume expands rapidly, pushing the piston to do work downward. Whether it is a diesel generator or a gasoline generator, each cylinder does work in turn according to a certain order, and the thrust acting on the piston becomes a force to push the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate.

Extended data:

1, functional characteristics of DC generator

DC generator has the characteristics of convenient use and reliable operation, and can directly provide electric energy for all kinds of electrical equipment that need DC power supply. But there is commutator in DC generator, which is easy to produce electric spark and has low power generation efficiency. In general, DC generators can be used as DC power sources for DC motors, electrolysis, electroplating, charging and alternator excitation.

2. Functional characteristics of alternator

Alternator refers to the generator that generates alternating current under the action of external mechanical force, which is divided into synchronous alternator and asynchronous alternator.

Synchronous generator is the most common alternator. These generators are excited by DC current, which can provide both active power and reactive power, and can be used to supply power to various load devices that need alternating current. In addition, according to the different prime movers used, synchronous generators can be divided into four types: turbine generators, hydro generators, diesel generators and wind generators.
