Functionality
The BMW electric valve (part number 11747810831) is a solenoid-operated vacuum control valve. It plays a crucial role in regulating the vacuum needed to operate various components such as the exhaust flaps or secondary air pump valves.
Here’s how it works:
- Operation: The solenoid within the valve is activated by an electrical signal from the vehicle’s control unit.
- Vacuum Regulation: When activated, the valve opens or closes to control the vacuum flow. This vacuum is essential for operating the exhaust flaps or secondary air pump valves.
- Exhaust Flaps: In the case of exhaust flaps, the valve helps manage the exhaust flow, which can improve engine performance and reduce emissions.
- Secondary Air Pump: For the secondary air pump, it aids in reducing emissions by injecting air into the exhaust stream to help burn off excess fuel.
This valve is critical for maintaining optimal engine performance and ensuring compliance with emission standards.
