Description
Product Overview
The fuel metering unit is assembled at the low-pressure intake end of the high-pressure common rail oil pump, receiving real-time vehicle electronic control signals to adjust the fuel supply volume entering the oil pump, thereby dynamically balancing the internal oil pressure of the oil rail. After long-term use, the valve core may wear, the sealing ring may age, and the electromagnetic coil may get stuck, resulting in unbalanced fuel supply flow, excessive or insufficient rail pressure, difficulty starting, and power loss. This product is a complete integrated metering valve assembly. It undergoes a complete set of flow accuracy and sealingity testing upon leaving the factory. The entire machine can be replaced without disassembling the oil pump, and it is suitable for heavy-duty trucks, mining construction machinery, and agricultural common rail diesel equipment fuel supply systems for major overhauls.
Unique core features of this product
Double-ear stamped metal flange base, resistant to heavy loads and vibration without shifting
Integrated double-ear installation flange, reserved standard fixing bolt holes, after assembly, it closely adheres to the oil pump housing; even under long-term heavy-load and bumpy driving conditions, the valve body will not loosen or shift, and the flow regulation accuracy remains stable for a long time.
Stainless steel integrated pressure-bearing valve body, resistant to diesel corrosion and high pressure
The main body is precisely machined by stainless steel, with surface passivation for rust prevention, and it is not prone to rust and deformation even when soaked in diesel for a long time or subjected to the oil pressure impact inside the oil pump, significantly reducing the probability of valve core sticking and flow control failure.
Front-end integrated green oil-resistant O-ring, one-step assembly sealing without oil leakage
A thickened green rubber sealing ring is pre-installed at the root of the outlet, after being installed in the oil pump mounting position, it fills the assembly gap, providing double barriers against low-pressure fuel leakage, and the maintenance does not require additional sealing gaskets, simplifying the assembly process.
Black card-type waterproof electronic control plug on the top, stable signal transmission and anti-interference
The upper side-by-side black plastic-sealed electronic control connector, with multiple layers of waterproof and dustproof rubber pads inside, isolating engine compartment oil splashing, rain, and dust erosion, the pins are less likely to oxidize and falsely connect during bumpy operations, and the electronic control adjustment signal has no delay or loss.
Built-in high-precision linear electromagnetic valve core, smooth flow regulation without jolts
The internal precise electromagnetic control valve core, with synchronous and rapid response to electronic control signals, linear regulation of fuel flow in idle, heavy load, and acceleration intervals, eliminating acceleration jolts, unbalanced high and low speed power, and excessive black smoke emissions. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, heavy-duty loaders, high-power stationary diesel generators, and heavy-duty diesel power supply systems for mining areas and construction sites that require 24-hour continuous full-load operation under high temperature and high dust conditions.
