What is the automotive ECM module?
1 Answers
The Engine Control Module (ECM) has the function of continuously monitoring and controlling the normal operation of the engine. In modern engine management systems, the ECM serves as its core control component. It can provide the engine with an optimal air-fuel mixture ratio and optimal ignition timing according to different engine operating conditions, keeping the engine always in its optimal working state and achieving peak performance in terms of power, fuel economy, and emissions. Below are relevant details: 1. Core component: The automotive Engine Control Module (ECM) is one of the most important automotive electronics. The core component of the ECM is a VLSI microcontroller composed of microprocessors, which collects control parameters through various corresponding sensors (temperature, pressure, gas-sensitive, displacement) to implement automatic control over engine operation, fuel injection, ignition, combustion, running, and emissions. The ECM is also connected to the vehicle's main computer via a bus. 2. Function: The automotive Engine Control Module (ECM) interacts with many emission-related components and systems, and monitors whether these components and systems exhibit performance degradation. OBD II diagnostics monitor system performance and set Diagnostic Trouble Codes (DTCs) when system performance degrades.
