What does EMS mean in cars?

[PeytonAnn]

Automotive EMS is the abbreviation for Engine-Management-System, which means engine management system in Chinese, commonly known as the engine computer. More information about automotive EMS is as follows: 1. In cars, the engine management system manages engine combustion, offering advantages such as low fuel consumption, low emissions, and high power. EMS collects signals from various sensors, such as engine air flow, coolant temperature, engine speed, camshaft position, throttle position, etc. 2. EMS processes this information, performs precise calculations, and outputs control signals. It precisely controls fuel supply, ignition timing, and idle air flow, thereby improving engine performance. Through precise control of fuel injection and ignition, pollutant emissions can be reduced; the use of oxygen sensors and three-way catalytic converters helps to lower harmful emissions.
