What Does Engine Performance Limitation Mean?

[NoraAnn]

Engine performance limitation refers to the restriction of engine power and horsepower through the settings of the engine control unit (ECU), aimed at prolonging the engine's service life. It indicates that the ECU has detected a fault and entered a safety mode to protect both the engine and the transmission. Here is an introduction to automotive engines: 1. Classification of engines: Based on different power sources, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. 2. 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 mechanical energy for piston movement and output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easier to start, and have lower manufacturing costs; diesel engines have higher compression ratios, better thermal efficiency, and superior economic and emission performance compared to gasoline engines.
