The following is a relevant introduction about automobile engines: 1. Function: The machine that provides power for automobiles, serving as the heart of a vehicle, affecting its power performance, fuel economy, and environmental friendliness. Depending on the power source, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems. 2. Types: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston motion and output power externally. Gasoline engines feature high rotational speed, light weight, low noise, easy starting, and low manufacturing costs. Diesel engines have high compression ratios, excellent thermal efficiency, and better economic performance and emission performance than gasoline engines.
