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 freight transportation, construction dust operations, continuous erosion by impure diesel, alternating cold and hot vibrations in the engine compartment conditions, the internal valve core sealing surface will wear, the nozzle spray holes will expand, and the internal sealing components will age and leak, resulting in single-cylinder fuel supply flow imbalance, 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 black anodized surface and a combined protective treatment of metal polishing, which can withstand thousands of bar of high-pressure fuel impact continuously, resist diesel medium corrosion, and withstand the temperature difference between the engine compartment, and the threads are not prone to slippage, the cylinder body is not prone to cracking or leaking, and maintains the high-pressure sealing performance of the oil circuit for a long time.
Side-mounted integrated inlet and outlet oil double interface, smooth and stable oil circuit pressure track
The side edge integrates an integrated and formed inlet and return oil double pipeline interface, without splicing gaps, reducing the resistance of high-pressure fuel flow, and the excess fuel can quickly return and relieve pressure, stabilizing the base oil pressure of the common rail system, eliminating the problem of high idle oil pressure and excessive single spray oil volume causing carbon deposits and black smoke in the cylinder.
Top-mounted integrated electromagnetic drive component, synchronous response without lag
The upper end is pre-assembled with a precise electromagnetic drive mechanism, the transmission of the electrical control signal is sensitive, the valve core reciprocates without delay, precisely controlling the single spray volume and the opening timing of the spray, ensuring the engine runs smoothly at idle, with linear acceleration power and no 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, and the internal is equipped with precise multi-micro-hole atomization spray holes, the high-pressure fuel is atomized into fine and uniform particles, the oil and gas are mixed fully, reducing carbon deposits in the cylinder and lowering 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 to isolate 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.
The entire machine is factory-calibrated 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 standard power output of the engine, significantly reducing the time for oil circuit maintenance and debugging.
