Description
Product Overview
The electronically controlled common rail injector receives ultra-high pressure fuel from the common rail pipe and relies on an external short-line electromagnetic component to receive electrical control unit signals, 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 work. Under long-term continuous heavy-load operation, continuous erosion by impure diesel fuel, frequent alternating high and low temperatures and vibrations, the internal valve core sealing surface will wear, the nozzle spray holes will deform, and the internal sealing components will age and leak, which will cause imbalance in the fuel supply flow of a single cylinder, continuous pressure loss in the high-pressure oil circuit, significant reduction in engine power, and increased black smoke emissions from the exhaust. This product is standardized in terms of installation dimensions, oil circuit interface specifications, and electromagnetic signal parameters. During maintenance, the entire injector can be directly replaced, eliminating the need to disassemble and debug the internal components separately. It is suitable for heavy-duty trucks, large construction machinery, and large-power diesel generator sets for maintenance and repair.
Core Advantages of the Single Product
Thickened segmented alloy steel cylinder body, high strength, pressure resistance, and anti-deformation, not prone to oil leakage
The cylinder body is precisely machined by CNC from thickened alloy steel, with surface passivation for rust prevention. It is suitable for installation on the heavy engine cylinder head structure, capable of enduring continuous impact from ultra-high pressure fuel for a long time, resisting corrosion from diesel medium and significant temperature changes, and the cylinder body is less likely to crack, and the threads are less likely to slip. It can maintain stable high-pressure oil circuit sealing performance over a long period.
Side-mounted integrated inlet and outlet return oil interface, smooth oil flow and stable track pressure
The side is integrated with a one-piece inlet and return oil pipeline interface, without splicing gaps, reducing the resistance of high-pressure fuel flow, and quickly returning excess fuel to relieve pressure, stabilizing the common rail system oil pressure, and improving the phenomenon of excessive fuel injection causing carbon deposits in the cylinder and black smoke emissions from the exhaust.
Exterior short-line precision electromagnetic drive component, stable signal transmission and rapid response
The upper end is equipped with an external short-line electromagnetic actuator, with a compact layout that is not prone to interference, stable electrical control signal transmission, timely valve core opening and closing action response, precise control of fuel injection volume and timing, ensuring smooth idle operation of the engine, and continuous smooth power output under heavy-load conditions.
Front multi-level stepped limit nozzle, precise positioning and uniform atomization
The front stepped limit structure automatically aligns and clamps during assembly without deviation; combined with multiple micro-hole precision spray holes, the high-pressure fuel is atomized finely and evenly, ensuring adequate oil-gas mixture, reducing carbon deposits in the cylinder, and optimizing fuel consumption levels under heavy-load conditions.
Multi-layer oil-resistant sealing structure, bidirectional anti-leakage and anti-air reverse suction
The cylinder body is equipped with multiple specifications of fluorine rubber oil-resistant sealing rings, which separate the high and low-pressure oil circuits, preventing high-pressure fuel from leaking outward; at the same time, it prevents air from reversing into the oil circuit after shutdown, solving the problems of starting oil circuit intake and slow oil pump pressure building.
Full-item factory test of the entire machine, no need for secondary adjustment during installation
Each injector independently completes electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow detection and calibration, with unified performance parameters. After assembly, it quickly restores the original power performance of the engine, significantly reducing the time for oil circuit maintenance and debugging.
