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 temperature differences in the engine compartment. The threads are not prone to slippage, the cylinder body is not prone to cracking or leaking, and maintains the long-term high-pressure sealing performance of the oil circuit.
The side-mounted integrated inlet and outlet oil dual interface ensures smooth and stable oil circuit pressure.
The side edge integrates an integrated and formed inlet and return oil dual pipeline interface, without splicing gaps, reducing the resistance of high-pressure fuel flow, and allowing excess fuel to quickly return and relieve pressure, stabilizing the base oil pressure of the common rail system, eliminating the problems of excessive idle oil pressure and excessive single-shot fuel injection volume causing carbon deposits and black smoke in the cylinder.
The top integrates an electromagnetic drive component, with synchronous response to the electrical control signal without delay.
The upper end is pre-assembled for the precise electromagnetic drive mechanism, with sensitive transmission of the electrical control signal, no delay in the valve core's reciprocating opening and closing action, precise control of the single-shot fuel injection volume and the timing of fuel injection, ensuring smooth engine idle, linear acceleration power without jolts.
The front end has multiple-level stepped limit nozzles, coaxially positioned for uniform atomization particles.
The front end has a multiple-level stepped limit positioning structure, automatically locking when installed in the cylinder head installation hole without deviation. The internal is equipped with precise multi-micro-hole atomization nozzles, with fine and uniform high-pressure fuel atomization particles, thorough oil-gas mixture, reducing carbon deposits in the cylinder and lowering 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 pump pressure building up during the next start.
The entire machine is factory-calibrated under all working conditions, and installation 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 fuel injection flow. The factory performance parameters are unified, and after assembly, it quickly restores the engine's standard power output, significantly reducing the time for oil circuit maintenance and debugging.
