Description
Product Overview
The electronically controlled common rail injector receives ultra-high pressure fuel from the common rail pipe and relies on an external wiring harness electromechanical 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 power generation. Under long-term continuous heavy-duty operation, continuous erosion by impure diesel, frequent alternating high and low temperatures and vibrations, the sealing surface of the internal valve core, the deformation of the nozzle spray holes, and the aging and leakage of internal sealing components 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 for separate disassembly and debugging of internal components. 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, high strength, pressure resistance, and resistance to deformation, and less oil leakage
The cylinder is precisely machined using CNC technology from thickened alloy steel, with a surface passivation anti-rust treatment. It is compatible with the installation structure of heavy-duty engine cylinder heads and can withstand continuous impact from ultra-high pressure fuel for a long time, resisting corrosion from diesel media and significant temperature variations. The cylinder is less likely to crack, the threads are less likely to slip, and it can maintain stable sealing performance of the high-pressure oil circuit over the long term.
Side-mounted integrated inlet and outlet return oil interfaces, smooth oil flow and stable track pressure
The side is integrated with an all-in-one inlet and return oil pipeline interface, reducing the resistance of high-pressure fuel flow through no gaps in the connection, allowing excess fuel to quickly return and relieve pressure, stabilizing the common rail system oil pressure, and improving the carbon deposition and black smoke emissions in the cylinder caused by excessive single-shot fuel injection.
Exterior wiring harness type precise electromechanical drive component, stable signal transmission and rapid response
The upper end is equipped with an external connection line electromechanical actuator. The electrical control signal transmission is stable, the valve core opening and closing action response is timely, precisely controlling the fuel injection volume and timing, ensuring smooth idle operation of the engine under heavy-duty conditions, and continuous smooth power output under heavy-duty 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; paired with multiple micro-hole precision spray holes, the high-pressure fuel is atomized finely and uniformly, ensuring adequate oil-gas mixture, reducing carbon deposition in the cylinder, and optimizing fuel consumption levels under heavy-duty conditions.
Multi-layer oil-resistant sealing structure, bidirectional anti-leakage and anti-air reverse suction
The cylinder is equipped with multiple specifications of fluororesin oil-resistant sealing rings, which isolate 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 up.
Complete itemized factory testing for the entire machine, no need for secondary calibration during installation
Each injector independently completes the detection and calibration of electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow, 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.
