An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.

The engine control module basically controls the intersection of the engine's necessary ingredients to make energy — fuel, air and spark. What does the engine control module do? It constantly monitors a vast network of sensors around the car to ensure conditions are within normal operating range.

The electronic engine control unit (ECU) is the central controller and heart of the engine management system. It controls the fuel supply, air management, fuel injection and ignition. Due to the scalability of its performance, the control unit is also able to control the exhaust system as well as to integrate transmission and vehicle functions.

2018年11月2日 · What is the ECM and how does it work? The Engine Control Module (ECM), also called the Engine Control Unit (ECU), ensures that your vehicle operates at optimal performance. The ECM monitors most of the sensors in the engine bay in order to manage your vehicle’s air-fuel mixture and regulate the emission control systems.

2025年1月30日 · An engine control unit (ECU) keeps a vehicle's engine running seamlessly. It is also frequently called an "electronic control unit or an engine computer" Several other terms refer to ECUs as well.

2023年10月15日 · This article explores the Electronic Control Unit (ECU), a critical component in modern automotive systems, known for its role in achieving precise control of engines and various vehicle systems. ECU functions as a microcomputer controller, processing data from sensors, executing instructions, and enhancing vehicle performance and efficiency.

In the Automotive industry, the term ECU often refers to an Engine Control Unit (ECU), or an Engine Control Module (ECM). If this unit controls both an engine and a transmission, it is often described as a Powertrain Control Module (PCM) .

In a modern vehicle, the Engine Control Unit (ECU) is a small computer that controls the way the engine works. It maximizes the efficiency and performance of a vehicle by adjusting the fuel-air mixture and ignition timing.

In this blog post, we cover the Engine Control Module and why it's important. The Engine Control Module, also known as the Powertrain Control Module (PCM) or Engine Control Unit (ECU), is an electronic device that controls various functions of an internal combustion engine.

2025年1月5日 · The Engine Control Unit is the high-tech control center of your car’s engine. It gathers data from sensors spread across the engine, processes this information, and adjusts key settings like fuel delivery and ignition timing.
