How Diesel Engines Work

diesel engine

A diesel engine is an internal combustion engine that uses diesel fuel as a fuel, and converts the heat energy released by the combustion of the fuel into mechanical energy.

working principle

Single-cylinder diesel engines include two-stroke diesel engines and four-stroke diesel engines. The mechanisms of the two are basically the same, and the main difference is in the valve structure.

Each working cycle of a single-cylinder diesel engine goes through four processes: intake, compression, power and exhaust. In a working cycle, only one stroke is for work, and the other three strokes are auxiliary strokes to create conditions for the power stroke. Therefore, the operation of the single-cylinder diesel engine is unstable. The development of single-cylinder diesel engines still relies on technological innovation, and constantly uses new technologies to improve the existing shortcomings and deficiencies of single-cylinder diesel engines and expand its scope of use. For example, it is equipped with fuel limiting devices, emission control devices, etc. to meet the needs of motor vehicle use and environmental protection, etc.
