Principles and core advantages of diesel engine technology
Diesel engines generate high temperatures (500-700 ℃) through compressed air, causing diesel to self ignite without the need for spark plugs. Its working cycle is divided into four stages: intake, compression, power generation, and exhaust, similar to gasoline engines, but with a different way of forming the mixture.
