What is the ignition point of diesel fuel?

[FinnRose]

Diesel fuel has an ignition point of 220°C. The flash point of diesel is above 55°C. Diesel is a light petroleum product, a complex mixture of hydrocarbons (with carbon atoms numbering approximately 10-22). It serves as fuel for diesel engines. Diesel is primarily produced by blending diesel fractions obtained through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced from shale oil processing and coal liquefaction. Classification of engines: Based on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. Principle of engines: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston motion to deliver power output. Gasoline engines feature high rotational speed, light weight, low noise, easy starting, and low manufacturing costs. Diesel engines have a higher compression ratio, superior thermal efficiency, and better economic performance and emission characteristics compared to gasoline engines.
