Product type
An Engine Control Unit (ECU) is a crucial component in modern vehicles, responsible for managing various engine functions and optimizing performance. It is typically made from durable electronic materials and houses a microcontroller that processes data from various sensors within the engine. The ECU interprets this data to control fuel injection, ignition timing, and emissions, ensuring efficient engine operation and compliance with environmental regulations.
| Material | Plastic housing with electronic components |
| Input voltage | 12V to 14V DC |
| Operating temperature range | -40°C to 125°C |
| Communication protocols | CAN, LIN, K-Line |
| Memory type | Flash memory and RAM |
When selecting an ECU, consider the specific requirements of the vehicle, including engine type and model. It is important to specify the necessary communication protocols and any compatibility with existing systems. Certifications such as ISO compliance and OEM specifications can also be important. Buyers should request information on memory capacity and processing speed, as well as quantities needed for production or replacement.
