Diesel Generator Working Principle and Components

1.Diesel Engine

The diesel engine is primarily composed of the cylinder block, cylinder head, crankshaft connecting rod mechanism, valve train and gear system, fuel supply system, lubrication system, cooling system, turbocharging and intercooling system, electrical system, intake and exhaust systems, and crankshaft ventilation device.

Classification of diesel engines:

By cooling system: air-cooled, water-cooled, open-loop, closed-loop.

By speed regulation method: mechanical centrifugal, mechanical hydraulic, electronic speed regulation, electronic fuel injection.

By displacement and cylinders: single-cylinder diesel engines and multi-cylinder diesel engines.

By working cycle: two-stroke diesel engines and four-stroke diesel engines.

2. Generator

The generator mainly consists of a rotor, stator, rectifier, voltage regulator, front and rear end covers, brushes, and brush holders.

Classification of generators:

By principle: synchronous generator, asynchronous generator, single-phase generator, three-phase generator.

By presence of brushes: brushed, brushless.

By excitation system: phase compound excitation, controlled phase compound excitation, third harmonic thyristor excitation, fundamental wave thyristor excitation, pulse width modulation, permanent magnet generator thyristor excitation.

Currently, brushless generators, fundamental wave thyristor excitation, and synchronous generators are mainstream products. In recent years, permanent magnet generator thyristor excitation has begun to gain market acceptance.

2.Control System

The main function of the control system is to monitor and control the operation process of the generator set, including measuring and displaying diesel engine operating parameters, measuring and displaying generator electrical quantities, controlling the generator output main circuit, protecting the diesel engine and generator, and controlling the generator set process.

Classification of control systems (by function): manual type, automatic type, and parallel operation type.

In addition to understanding the unit structure, we also need to know the factors affecting the price of diesel generators. Many netizens ask about the cost of an xx-kilowatt generator. The price is closely related to the configuration. For example, an ordinary configuration of a domestic Yuchai generator set is estimated at 100,000 yuan, while a high-end configuration may cost more than 150,000 yuan, showing a significant price difference. Moreover, this is just one of the factors influencing the price; other factors include generator set power, brand, and market demand. Therefore, it is reasonable to conduct a comprehensive investigation when purchasing a generator set.
