What does EMS malfunction mean?

[RafaelLee]

An EMS malfunction in a car means the engine cannot start, and throttle valve noise may indicate a burnt-out oil-gas separator. EMS stands for Engine-Management-System, which translates to engine management system in Chinese, commonly referred to as the engine computer. Here are the details: How car EMS works: The EMS collects signals from various sensors, such as engine air flow, coolant temperature, engine speed, camshaft position, throttle position, etc. The EMS processes this information, performs precise calculations, and outputs control signals. It precisely controls fuel supply, ignition timing, and idle air flow, improving engine performance. Through precise control of fuel injection and ignition, it can reduce pollutant emissions; the use of oxygen sensors and three-way catalytic converters helps lower harmful emissions. Technical features: The engine valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to the hydraulic tappet valve drive mechanism commonly used in gasoline engines today, this innovative valve drive mechanism has the advantage of relatively low friction torque, effectively reducing engine power consumption and lowering fuel consumption.
