What does the car ECU mean?

[DiLucia]

ECU is the engine control unit. Here is more information about the ECU: 1. The ECU is referred to as the brain of the engine. Without the ECU, the car's engine cannot operate normally. During engine operation, the ECU collects data and, after processing, controls the engine's operation through control mechanisms. 2. There are many sensors and actuators around the car's engine, and the sensors can transmit data to the ECU. 3. After processing, the ECU can adjust the engine's operating state through the actuators. 4. The ECU is generally installed in the engine compartment.
