What does EMS mean in a car?

[MorganMarie]

Engine Management System (abbreviated as EMS) Here is some relevant information: 1. EMS uses various sensors to convert conditions such as the amount of air intake, coolant temperature, engine speed, and acceleration/deceleration into electrical signals, which are then sent to the controller. 2. The controller compares this information with stored data, performs precise calculations, and outputs control signals. EMS can not only accurately control fuel supply, replacing the traditional carburetor, but also manage ignition timing and idle air flow, significantly improving engine performance. 3. The engine valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to the commonly used hydraulic tappet valve drive mechanism in current gasoline engines, this innovative valve drive mechanism has the advantage of relatively lower friction torque, effectively reducing engine power consumption and fuel consumption.
