The Difference Between Diesel Generator and Engine

Today we will briefly introduce the difference between diesel generator and engine.

Generator: Invented by Faraday on September 23, 1831, it is a motor that converts mechanical energy into electrical energy. Usually driven by a steam turbine, a water turbine or an internal combustion engine. Electric energy is one of the most important energy sources in modern society. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. Generators are divided into two categories: DC generators and AC generators. The latter can be divided into two types: synchronous generator and asynchronous generator. Synchronous generators are most commonly used in modern power stations.

The generator is mainly composed of stator, rotor, end cover, brush, frame and bearing. There are also two types of generators: AC and DC generators. The rotor is connected to the driving machine and is driven by the driving machine to rotate. DC passes through the rotor winding and generates a magnetic field. The magnetic field lines of this rotating magnetic field cut the windings in the stator of the generator, thereby An electrical potential is generated in the stator windings, and multiple windings are connected in series to form a voltage and output power.

The commonly used generators are gasoline generators, diesel generators, and wind turbines. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, diesel engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine applies to both the power generating unit and the entire machine including the power unit (eg gasoline engine, aircraft engine). The engine was first born in the United Kingdom, so the concept of the engine is also derived from English, and its original meaning refers to the kind of "mechanical device that generates power".

Engines generally include internal combustion engines, steam engines, etc., mainly to convert chemical energy in gasoline, diesel and other fuels into mechanical energy. Rotating machinery driven by other media other than electricity, from the perspective of driving media, there are natural gas, gasoline, diesel, heavy oil, water, tide, wind, etc.; from the perspective of machinery, there are fuel and gas three-stroke, four-stroke, two-stroke engines, Steam turbines, water turbines, oil or gas turbines, wind turbines, etc.

Diesel engine is a complete set of power output equipment, including a transmission gear, an engine, and a transmission shaft. It can be seen that the engine is only a part of the entire engine, but it is the core part of the entire engine. People continue to develop various types of engines, which can be mainly divided into three categories: internal combustion engines, external combustion engines, and electric motors.
