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 spraying it into the cylinder to complete combustion and power generation. Under long-term road driving, continuous erosion by impurities in diesel, alternating vibrations in the engine compartment under hot and cold conditions, the internal valve core sealing surface wears out, the nozzle spray holes expand, and the internal sealing components age and leak, resulting in imbalance in the fuel supply flow of 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 dimensions, oil circuit interface specifications, 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. It is suitable for the maintenance of light pickup trucks, light freight vehicles, small construction machinery, and small diesel generator sets.
Core advantages of this product:
The slender segmented composite alloy steel integrated cylinder body is rust-resistant, withstands pressure, and is not prone to deformation or oil leakage.
The cylinder body is segmented and formed by CNC machining of alloy steel, with surface passivation protection treatment, suitable for narrow cylinder head installation space, capable of long-term withstanding the continuous impact of high-pressure fuel, resisting diesel medium corrosion, and withstanding 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.
The side-mounted integrated dual oil inlet and outlet interfaces ensure smooth and stable oil circuit pressure.
The side-side integrated and formed inlet and return oil dual pipeline interfaces eliminate splicing gaps and reduce the resistance of high-pressure fuel flow, allowing excess fuel to quickly return and relieve pressure, stabilizing the base oil pressure of the common rail system, eliminating the problem of excessive oil pressure at idle speed and excessive single spray oil volume causing carbon deposits and black smoke in the cylinder.
The top integrates an electromagnetic drive component, with synchronous response and no delay of the electrical control signal.
The upper end is pre-assembled for the precise electromagnetic drive mechanism, with sensitive transmission of the electrical control signal, no delay in the reciprocating opening and closing action of the valve core, precise control of the single spray volume and spray opening timing, ensuring smooth idle speed and linear acceleration power without jolts.
The front-end multi-level stepped limit nozzle has coaxial positioning for uniform atomization particles.
The 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, with fine and uniform high-pressure fuel atomization particles, thorough oil-gas mixture, reducing carbon accumulation in the cylinder and reducing fuel consumption.
The internal has multiple layers of oil-resistant sealing structures, blocking 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 preventing air from backflowing into the oil circuit after shutdown, avoiding slow oil pressure build-up when starting next time, and reducing the problem of excessive black smoke emissions from the exhaust.
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 time, 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. List of Accessories
