Description
Product Overview
The electronically controlled common rail injector receives 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 spraying it into the cylinder to complete combustion and power generation. Under long-term load operation, impurities from diesel washing, and continuous vibration under high and low temperatures, the sealing surface of the internal valve core, the nozzle spray holes, and the sealing parts will age and leak, causing unbalanced fuel supply for a single cylinder, pressure loss in the high-pressure oil circuit, decreased engine power, and increased black smoke emissions from the exhaust. This product is standardized in its installation dimensions, oil circuit interface specifications, and electromagnetic signal parameters. During maintenance, the entire set of injectors can be directly replaced, eliminating the need for individual adjustment of internal components, and is suitable for medium-sized freight vehicles, medium-sized construction machinery, and diesel generator sets for maintenance and use.
Core advantages of this product:
Thickened segmented alloy steel cylinder body, high strength, pressure resistance, and anti-deformation, and not prone to oil leakage
The cylinder body is precisely machined by CNC from thickened alloy steel, with surface passivation for rust prevention, suitable for installation on the cylinder head of medium-sized engines, capable of long-term withstanding high-pressure fuel impact, resisting diesel corrosion and temperature changes, the cylinder body is less likely to crack, and the threads are less likely to slip, maintaining stable high-pressure oil circuit sealing for a long time.
Side-mounted integrated inlet and outlet return oil interface, smooth oil flow and stable track pressure
The side integrates an integrated and formed inlet and return oil pipeline interface, without splicing gaps, reducing fuel flow resistance, excess fuel quickly returns and depressurizes, stabilizing the common rail system oil pressure, and improving the phenomenon of cylinder carbon deposition and black smoke emissions caused by excessive single-time fuel injection.
Top precision electromagnetic driving component, rapid and no-delay signal response
Pre-assembled on the top for the electromagnetic actuator, the electrical control signal is sensitive, the valve core opening and closing action responds promptly, precisely controlling the fuel injection volume and timing, ensuring smooth idle engine operation and smooth acceleration power output.
Front-end multi-level stepped limit nozzle, precise positioning and uniform atomization
The front-end 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, the oil and gas are fully mixed, reducing the generation of cylinder carbon deposits, and optimizing fuel consumption levels.
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, layering to isolate high and low-pressure oil circuits, preventing fuel leakage outward; at the same time, it prevents air from reversing into the oil circuit after shutdown, solving the problem of starting oil circuit intake and slow oil pump pressure building.
Full-item factory testing of the entire machine bench, no need for secondary calibration when installed
Each injector independently completes electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow detection calibration, with unified performance parameters. After assembly, it quickly restores the original power performance of the engine, shortening the time for oil circuit maintenance and debugging. List of Accessories
