0928400802 Fuel Metering Valve

Product Overview

This product is a fuel inlet metering valve (IMV), a key component in the common rail system of diesel engines. It is compatible with various fuel supply pumps and can be used as a replacement. Its core function is to control the fuel input quantity, output volume, and pressure within the fuel rail of the fuel supply pump, helping to optimize engine operation. The relevant product OE number is 1465ZS0014, corresponding to part number 0928400802.

Features

Precise control core: Based on the fuel pressure in the fuel rail, adjust the amount of fuel entering the high-pressure chamber of the high-pressure pump; control the fuel flow rate of the diesel engine common rail system, as well as the output volume of the fuel supply pump and the fuel rail pressure.
Dual mechanism of action: When energized, the electromagnet force works in conjunction with the spring to increase fuel pressure by reducing the valve opening; at the same time, it can also act as a mechanical pressure damper to suppress the high-frequency pressure pulses generated by the radial plunger pump (when fewer than three pistons are working).
Installation and compatibility: Mounted on the side of the high-pressure fuel pump, controlled by the engine control unit (ECU), compatible with various fuel supply pumps, and has wide applicability for replacement.
Environmental and energy-saving advantages: It enables the fuel supply pump to compress only the amount of fuel required to maintain the pressure, reducing the engine operating load and thus reducing emissions; it also reduces fuel flow during operation, thereby lowering fuel temperature.
Sensitivity to use: Very small tolerances, easily affected by contaminated fuel or carbon deposits; excessive wear, fuel contamination or electrical failures can all lead to driving performance problems and abnormal fuel pressure.
