Product Overview
The fuel injectors are installed above the cylinder head and receive electronic control signals to precisely regulate the amount and timing of high-pressure fuel injection, achieving thorough combustion in layers. Under long-term urban short-distance, high-temperature engine compartments, and diesel contamination erosion conditions, the valve core sealing surface may wear, the sealing rubber ring may age, and the electromagnetic valve may have a delayed response. This can result in unbalanced single-cylinder power output, low-speed engine stalling, excessive black smoke in exhaust, and fuel leakage into the engine oil to dilute the lubricating medium. This product is an integrated finished fuel injector. The installation outer diameter, return oil interface, and electronic control plug specifications are standardized, and the spray curve is uniformly calibrated at the factory. Maintenance and replacement do not require additional debugging. It is suitable for the maintenance of light-duty trucks, pickups, and small construction machinery equipped with high-pressure common rail engines.
Product Core Advantages
Thickened black die-cast valve body, resistant to vibration and high-temperature deformation
Integrated die-cast housing with strengthened outer wall structure, capable of withstanding long-term vibration and continuous high-temperature in urban roads, less likely to cause shell cracking or oil leakage at the joint surface, maintaining a stable internal high-pressure fuel environment.
Independent low-pressure return oil branch pipe on the side, rapid pressure relief without air resistance
Independent lateral return oil channel, capable of quickly discharging excess reflux fuel, eliminating oil path air resistance, avoiding continuous fluctuation of rail pressure, and improving the problem of difficulty in starting the cold engine after multiple ignitions.
Waterproof and insulated electronic control plug at the top, stable signal transmission
Integrated black electronic control plug terminals, with gold-plated conductive contacts, and an outer insulation sleeve that prevents erosion by diesel and water vapor. The electronic control signal has no delay, smooth pre-spray and main spray switching, eliminating acceleration power jolts.
Multi-level ring-shaped sealing groove fuel injector nozzle at the front end, layer-sealing to prevent gas leakage
The fuel injector rod adopts a multi-track ring-shaped sealing positioning design, which can be combined with O-rings to achieve layer isolation, effectively preventing high-temperature gas in the combustion chamber and high-pressure fuel from leaking; the front end is equipped with multiple micro-hole mirror-shaped spray holes, ensuring uniform and fine fuel atomization, reducing carbon deposits and black smoke in the exhaust. The white plastic dust-proof plugs at both ends protect the precise structure throughout.
Pre-installed transparent white protective plugs at the oil inlet and fuel injector ends for sealing the precise holes during storage, transportation, disassembly, and maintenance, preventing dust and impurities from entering the valve core and avoiding nozzle blockage and valve core jamming and sticking.
The entire machine is factory-calibrated for flow rate, opening pressure, and atomization effect. After replacement, the idle speed is stable, the power output is linear, and the maintenance and debugging time is significantly reduced.
Applicable Scenarios
