How does an ECU work?

[VonMaci]

It performs calculations, processing, and judgments on the information input from the air flow meter and various sensors based on the programs and data stored in its memory. Then, it outputs commands to provide the fuel injector with electrical pulse signals of a certain width to control the fuel injection volume. The ECU consists of a microcomputer, input, output, and control circuits. Below is an introduction to the ECU: 1. The ECU, or Electronic Control Unit, is also known as the "vehicle computer" or "on-board computer." In terms of its purpose, it is a specialized microcomputer controller for automobiles. The operating voltage range of an ECU is generally 6.5-16V, the operating current is 0.015-0.1A, and the operating temperature ranges from -40°C to 80°C. It can withstand vibrations below 1000Hz, so the probability of ECU failure is very low. 2. In the ECU, the CPU is the core component, which has the function of calculation and control. When the engine is running, it collects signals from various sensors for calculation and converts the results into control signals to manage the operation of controlled objects.
