What are the types of engines?

As the core device of modern mechanical power, engines can be divided into various types according to their working principles and energy types, and are widely used in the fields of automobiles, aviation, ships, and industry. The following are the main classifications of engines:

1、 Classified by fuel type

Gasoline engine: using gasoline as fuel and igniting through spark plugs, it has the characteristics of high speed and low noise, and is commonly used in passenger cars.

Diesel engine: operates in compression ignition mode, with high thermal efficiency and high torque, commonly used in trucks, construction machinery, and heavy vehicles.

Gas engine: using natural gas or liquefied petroleum gas as fuel, with relatively clean emissions, suitable for buses and some household vehicles.

2、 Classified by working principle

Reverse piston engine: It generates power through the reciprocating motion of the piston in the cylinder and is currently the most common form of engine.

Rotary engine: using triangular rotor rotation motion instead of piston reciprocating motion, compact structure but high fuel consumption.

Turbine engines: including gas turbines and jet engines, which generate thrust through high-speed rotating turbines and are mainly used in the aviation industry.

3、 Classified by cylinder arrangement

In line engine: The cylinders are arranged in a straight line, with a simple structure and easy maintenance.

V-shaped engine: The cylinders are arranged in a V-shape, which can reduce the length of the engine and improve space utilization.

Horizontal opposed engine: The cylinders are arranged horizontally relative to each other, with a low center of gravity and smooth operation.

In addition, with the increasing demand for environmental protection, new energy power systems such as hybrid engines and pure electric motors are becoming increasingly popular. Different types of engines have their own advantages and disadvantages, and users should choose the appropriate engine type based on their specific usage needs.
