Description
Product Overview
The electronically controlled common rail injector receives the ultra-high pressure fuel from the common rail pipe and, relying on the top electromagnetic components, receives the electrical control unit's signal to drive the internal precision valve core to open and close rapidly. It then splits the high-pressure fuel into fine oil mist and injects it into the cylinder to complete combustion and power generation. Under long-term road driving, continuous erosion by impurities in 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. This can result 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. 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.
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 pipelines interface eliminates splicing gaps and reduces the resistance of high-pressure fuel flow. Excess fuel can 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 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, ensuring sensitive transmission of the electrical control signal and 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 ensures smooth engine idle speed, 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 precision multi-micro-hole atomization nozzles are provided. The high-pressure fuel is atomized into fine and uniform particles, ensuring adequate oil-gas mixture and reducing carbon deposits in the cylinder and fuel consumption.
The internal multi-layer oil-resistant sealing structure prevents leakage and air backflow.
The cylinder body is equipped with multiple specifications of oil-resistant fluorine rubber sealing gaskets, which separate the high and low-pressure oil circuits and prevent high-pressure fuel from leaking through assembly gaps. At the same time, it prevents air from backflowing into the oil circuit after shutdown and avoids slow oil pump pressure build-up during the next start-up.
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 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.
