Description
Product Overview
The electronically controlled common rail injector receives the ultra-high pressure fuel from the high-pressure common rail pipe and relies on the top electromagnetic component to receive the signal from the electronic control unit, driving the internal valve core to complete precise opening and closing, and atomizing the fuel into fine droplets before spraying it into the cylinder to complete combustion and power generation. Under long-term heavy mining conditions, long-distance jolting, continuous erosion by impure diesel, and high-temperature vibration in the engine compartment, the sealing surface of the internal valve core may wear, the nozzle spray holes may expand, and the oil circuit sealing components may age and leak. This may result in single-cylinder fuel supply imbalance, rapid pressure loss in the rail, power reduction, and excessive black smoke emissions from the exhaust. This product has standardized processing for installation threads, oil circuit interfaces, and electromagnetic signal parameters. During maintenance, the entire injector can be directly replaced, eliminating the cumbersome process of disassembling and grinding the precise internal components. It is suitable for medium-sized heavy-duty trucks, wheeled loaders, small and medium-sized mining excavators, and fixed diesel generator sets for maintenance and repair.
Core Advantages of the Single Product
Segmented composite alloy steel housing, double-layer rust-proof and pressure-resistant without deformation or leakage
The cylinder body is segmented and formed by a single-piece alloy steel turning process. The surface undergoes black passivation + metal polishing composite treatment, which can withstand thousands of bar of high-pressure fuel impact, resist temperature differences between the engine compartment and diesel medium corrosion, and has less tendency to slip on the threads and less tendency to crack and leak the shell.
Side-mounted integrated inlet and outlet oil dual interfaces, smooth oil circulation and stable oil pressure
The side is integrated with dual pipelines for inlet and return oil interfaces. They are cast as a whole without any joint gaps. The resistance to high-pressure fuel flow is small, and the excess fuel flows back quickly to relieve pressure, stabilizing the base oil pressure of the common rail system and eliminating high idle oil pressure, excessive injection, and carbon buildup problems.
The top integrates an electromagnetic drive control component, with synchronous and no-delay signal response
The upper end is pre-assembled with a precise electromagnetic drive mechanism. The transmission of the electronic control signal is sensitive, and the valve core opening and closing actions have no lag. Precise control of the single injection volume and injection opening timing is achieved, ensuring smooth engine idle and linear acceleration without jolts.
Front-end multi-level stepped limit nozzles, coaxial positioning for uniform atomization
The front-end multi-level stepped limit positioning structure automatically positions and does not shift when installed in the cylinder cover. The internal is equipped with precise atomization holes, and the high-pressure fuel is atomized into fine and uniform particles, ensuring adequate oil-gas mixture and reducing carbon accumulation in the cylinder, thereby reducing fuel consumption.
Built-in multi-layer oil-resistant sealing structure, bidirectional barrier against fuel leakage and air intake
The shell is equipped with multiple specifications of fluorine rubber sealing gaskets. The layers isolate the high and low-pressure oil circuits, preventing high-pressure fuel from leaking through assembly gaps and preventing air from being sucked into the oil circuit during shutdown, avoiding slow oil pressure build-up upon next startup.
The entire machine undergoes full-condition bench testing before leaving the factory, and no secondary calibration is required when installed on the vehicle
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 injection flow. The factory performance parameters are unified, and after assembly, the engine's standard power output is quickly restored, significantly reducing the time for oil circuit maintenance and debugging.
