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 road driving, continuous erosion by impure diesel, alternating cold and hot vibrations in the engine compartment, 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 the Single Product
The slender segmented composite alloy steel integrated cylinder body is rust-proof, resistant to pressure, and does not deform or leak.
The cylinder body is segmented and formed by CNC machining of alloy steel, with surface passivation protection treatment. It is suitable for narrow cylinder head installation space and can withstand the continuous impact of high-pressure fuel for a long time, resisting diesel medium corrosion, high and low temperature temperature differences in the engine compartment, and having threads that are not prone to slippage and the cylinder body that is not prone to cracking or leaking. It maintains the high-pressure sealing performance of the oil circuit for a long time.
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, reducing 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 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 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 spray volume and spray opening timing, ensuring smooth engine idle, 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, with internal precision multi-micro-hole atomization spray holes. The high-pressure fuel is atomized into fine and uniform particles, fully mixing with oil, reducing carbon accumulation in the cylinder and lowering fuel consumption.
Built-in multi-layer oil-resistant sealing structure, 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 also preventing air from backflowing into the oil circuit after shutdown, avoiding slow oil pressure build-up when starting next time, and ensuring the engine's standard power output is quickly restored after assembly, significantly reducing the time for oil circuit maintenance and debugging.
Whole-machine factory calibration under all working conditions, no need for secondary calibration when installed
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. 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.
