Description
Product Overview
The electronically controlled common rail injector receives the ultra-high pressure fuel from the common rail pipe and relies on the top electromagnetic component to receive the electrical control unit's signal, driving the internal precision valve core to open and close rapidly, splitting the high-pressure fuel into fine oil mist and injecting it into the cylinder to complete combustion and power generation. Under long-term urban and rural long-distance transportation, construction dust operations, continuous erosion by impure diesel, alternating cold and hot vibrations in the engine compartment conditions, the sealing surface of the internal valve core will wear, the nozzle's spray holes will expand, and the internal sealing components will age and leak, resulting in unbalanced fuel supply to a single cylinder, rapid pressure relief in the high-pressure oil circuit, attenuation of engine power output, and excessive black smoke emissions from the exhaust. This product has standardized processing for installation thread specifications, oil circuit interface dimensions, and electromagnetic signal matching parameters. During maintenance, the entire set of injectors can be directly replaced, eliminating the cumbersome process of disassembling and debugging the internal precision components, and it is suitable for medium-sized heavy-duty freight trucks, small and medium-sized wheeled loaders, small and medium-sized mining excavators, and fixed diesel generator sets for maintenance.
Core Advantages of the Single Product
Segmented composite alloy steel integrated cylinder body, double-layer rust-proof and pressure-resistant without deformation or oil leakage
The cylinder body is segmented and formed by CNC machining of alloy steel, with a surface of black passivation and metal polishing combined protective treatment, capable of enduring thousands of bar of high-pressure fuel impact for a long time, resisting diesel medium corrosion, engine compartment temperature difference, and thread not slipping, cylinder body not cracking or leaking, and maintaining long-term high-pressure oil circuit sealing performance.
Side-mounted integrated inlet and outlet oil dual interfaces, smooth and stable oil circuit pressure track
The side edge integrates an integrated and formed inlet and return oil dual pipeline interface, without splicing gaps to reduce the resistance of high-pressure fuel flow, excess fuel can quickly return and relieve pressure, stabilize the base oil pressure of the common rail system, eliminate idle oil pressure being too high and excessive single spray oil volume causing carbon deposits in the cylinder and black smoke problems.
Top-mounted integrated electromagnetic drive component, synchronous response without lag of electrical control signal
The upper end is pre-assembled with a precise electromagnetic drive mechanism, the electrical control signal transmission is sensitive, the valve core reciprocates without delay, precisely controlling the single spray oil volume and the opening timing of the spray, ensuring the engine idle is stable, acceleration power is linear without jolts.
Front-end multi-level stepped limit nozzle, coaxial positioning for uniform atomization particles
The front-end multi-level stepped limit positioning structure automatically locks when installed in the cylinder head installation hole, with internal supporting precision multi-micro-hole atomization spray holes, high-pressure fuel is atomized into fine and uniform particles, the oil and gas are mixed fully, reducing carbon deposits in the cylinder interior and reducing fuel consumption.
Built-in multi-layer oil-resistant sealing structure, bidirectional barrier against leakage and air backflow
The cylinder body is equipped with multiple specifications of oil-resistant fluorine rubber sealing gaskets, layering isolates high and low pressure oil circuits, preventing high-pressure fuel from leaking out through assembly gaps, and also preventing air from backflowing into the oil circuit after shutdown, avoiding slow oil pressure build-up when starting next time, and reducing oil circuit intake air.
The entire machine is factory-tested under all working conditions, and installation on the vehicle does not require secondary calibration
The entire injector is independently tested on the machine for electromagnetic response speed, high-pressure sealing and pressure retention duration, uniformity of atomization, and standard spray flow, with unified factory performance parameters. After assembly, it quickly restores the engine's standard power output, significantly reducing the time for oil circuit maintenance and debugging. Applicable scenarios
This product is suitable for medium-sized heavy-duty freight trucks with high-pressure common rail fuel supply systems, small and medium-sized wheeled loaders, small and medium-sized mining excavators, and medium-sized fixed diesel generators. It is applicable for long-distance urban and rural freight transportation, moderate dust operations at construction sites, heavy-duty farming in fields, and medium-sized electric control common rail diesel engines operating in corrosive environments with impurities in diesel fuel.
