0928400612 Fuel Metering Valve
Core functions and working principles
1. Installation location
It is usually installed on the fuel supply pump of the fuel injection system, and some models are located on the side of the high-pressure fuel pump, directly linked to the fuel supply system.
2. Core Control Logic
As a key component of the electronic control unit (ECU), its core function is to precisely control the flow of fuel entering the high-pressure common rail, thereby regulating the amount of fuel flowing into the fuel line and achieving refined management of the engine's fuel supply.
3. Specific working mechanism
When the valve is activated, the force generated by the electromagnet works in conjunction with the spring force to reduce the valve opening, thereby increasing the fuel pressure. At the same time, the valve can also act as a mechanical pressure damper, effectively smoothing high-frequency pressure pulses and ensuring stable fuel pressure when the radial plunger pump has fewer than three activated pistons.
Core Product Advantages
1. Ensure normal engine operation: Through precise fuel flow control, ensure stable fuel supply under various engine operating conditions and avoid operational failures caused by abnormal fuel supply.
2. Improve fuel economy: Keep the engine running at its most fuel-efficient state, reduce unnecessary fuel consumption, and achieve significant fuel savings.
3. Reduced emissions and operating load: The fuel supply pump only compresses the amount of fuel required to maintain the pump pressure, reducing the engine operating load and indirectly reducing pollutant emissions, thus meeting environmental protection requirements.
4. Control fuel temperature: Reducing fuel flow during operation can effectively lower fuel temperature and extend the service life of fuel system components.
5. High adaptability: As a universal replacement part for multiple fuel supply pumps, it can meet the adaptation requirements of different high-pressure pump models, with high versatility and ease of maintenance.
