Electronic control systems primarily consist of three major components: signal input devices, electronic control units (ECU), and actuators. Here is a detailed explanation: 1. An electronic control system (abbreviated as ECS) refers to an automatic control system that uses electronic devices such as computers as control devices. 2. Signal input devices are various sensors. The function of sensors is to collect various physical and chemical information required by the control system and convert it into electrical signals, which are then transmitted to the ECU via wiring. 3. The electronic control unit (ECU) is a comprehensive control electronic device. Its function is to receive the reference (baseline) voltage provided by each sensor, accept electrical signals input by sensors or other devices, and store, calculate, and analyze the received signals. Based on the results of calculations and analysis, it issues commands to the actuators. 4. Actuators are devices controlled by the output commands of the ECU, specifically executing certain control functions.

Why does white smoke come out of the exhaust pipe when starting a cold engine?

Here is an introduction to the reasons why white smoke comes out of the exhaust pipe when starting a cold engine: 1. The phenomenon of white smoke from the car is very common in winter, because the white smoke seen is basically water vapor. Under normal circumstances, the water vapor produced after gasoline combustion is discharged normally through the exhaust pipe. Since the ambient temperature is relatively low, the water vapor will condense into small water droplets and become visible water vapor to the naked eye. 2. There is a fault. Because some coolant enters the cylinder and is discharged with the exhaust gas, and because the temperature is very high, it will come out in the form of water vapor.
