What is an engine

An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Internal combustion engines typically convert chemical energy into mechanical energy. The engine is applicable to both the power generation device and the entire machine including the power device (such as gasoline engines, aircraft engines). The engine was first born in the UK, so the concept of the engine also originated from English. Its original meaning refers to the "mechanical device that generates power".
On December 27, 2024, the first 600kg thrust turbofan engine independently developed by Sichuan Tianfu Light Power Technology Co., Ltd. was officially ignited.
