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 sealing surface of the internal valve core wears out, the nozzle's 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, temperature differences in the engine compartment, and being less prone to thread slippage and cylinder body cracking and leakage. 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 oil pressure at idle speed and excessive single-shot fuel injection volume causing carbon deposits in the cylinder and black smoke.
The top integrates an electromagnetic drive component, synchronously responding to the electrical control signal without lag.
The upper end is pre-assembled with a 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-shot fuel injection volume and the timing of fuel injection, ensuring smooth engine idle speed and linear acceleration power without jolts.
The front end has multi-level stepped limit nozzles, coaxially positioned and atomized particles are uniform.
The front end has a multi-level stepped limit positioning structure, which automatically locks when installed in the cylinder head installation hole without deviation. 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 thoroughly, 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 also 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.
