Description
Product Overview
The electronically controlled common rail injector receives 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 load operation, impurities in diesel washing, continuous vibration under high and low temperatures, the wear of the internal valve core sealing surface, deformation of the nozzle spray holes, and aging and leakage of the sealing components will cause unbalanced fuel supply for a single cylinder, pressure loss in the high-pressure oil circuit, decrease 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 individual adjustment of internal components, and is suitable for maintenance and use of light-duty trucks, pickups, medium-sized construction machinery, and diesel generator sets.
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 surface passivation for rust prevention. It is compatible with the installation structure of medium-sized engine cylinder heads and can withstand the impact of high-pressure fuel for a long time, resist diesel corrosion and temperature changes, and is less likely to crack or have loose threads. It can maintain the sealing performance of the high-pressure oil circuit stably for a long time.
Side-mounted integrated return oil interface, smooth and stable oil flow and track pressure
The side-mounted integrated return oil connector is formed by a single molding process, reducing the resistance of fuel flow and eliminating the gap between joints, allowing excess fuel to quickly return and relieve pressure, stabilizing the common rail system oil pressure, and improving the phenomenon of cylinder carbon buildup and black smoke emissions caused by excessive fuel injection in a single shot.
Top-mounted precision electromagnetic driving component, rapid and no-delay signal response
The upper end integrates an electromagnetic actuator, with a compact and stable structure, sensitive electrical control signal sensing, timely valve core opening and closing action response, precise control of fuel injection volume and timing, ensuring smooth idle operation of the engine and smooth acceleration power output.
Precise atomization nozzle at the front end, uniform atomization and complete combustion
The nozzle is precisely ground and processed, with fine oil atomization particles, complete oil-gas mixture, effectively reducing carbon buildup in the cylinder, optimizing fuel consumption levels, and reducing exhaust emissions.
Multi-layer oil-resistant sealing structure, bidirectional anti-leakage, and anti-airflow backflow
The cylinder is equipped with multiple specifications of fluorine rubber oil-resistant sealing rings, which isolate the high and low-pressure oil circuits layer by layer to prevent fuel leakage outward; at the same time, it prevents air backflow into the oil circuit after shutdown and solves the problems of starting oil circuit intake and slow oil pump pressure building-up.
Full-item factory testing of the entire machine platform, no need for secondary calibration when installed
Each injector independently completes electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow detection calibration. The performance parameters are unified, and after assembly, it quickly restores the original power performance of the engine, reducing the time for oil circuit maintenance and debugging.
