Description
Product Overview
The electronically controlled single-body injector relies on the cam-driven spring to achieve high-pressure fuel injection. The electronically controlled connector transmits the fuel injection signal to precisely control the injection timing and fuel quantity, suitable for large-displacement heavy-duty diesel equipment. Under long-term mining conditions of 24-hour continuous heavy load, ultra-high fuel pressure reciprocating impact, and poor-quality impure diesel erosion, the needle valve sealing surface will wear, the sealing ring will age due to high temperature, and the electromagnetic coil suction force will weaken. This may result in single-cylinder fuel shortage, significant reduction in overall engine power, difficulty in cold start, excessive black smoke emissions from the exhaust, and oil leakage. This product has unified standardization of spring elasticity, fuel injection opening pressure, and electronic control signal parameters. Maintenance can be directly carried out by replacing the entire unit without on-site grinding and adjustment. It is suitable for large-scale mining excavators, heavy-duty loaders, long-distance trucks, and large-power stationary diesel generators for maintenance.
Core Advantages of the Single Unit
Segmented mirror-hardened alloy steel housing, resistant to pressure, wear, and high-temperature deformation
Multi-stage stepped hardened metal body, with mirror finish ultra-precision grinding on the inner and outer walls, high bearing strength, long-term continuous impact of ultra-high pressure fuel, and the engine compartment's high-temperature environment is not prone to rust and deformation, effectively blocking the backflow of high-pressure fuel leakage.
Double-layer purple fluororubber sealing ring, double-layer barrier against leakage and gas backflow
Two sets of integrated purple oil-resistant fluororubber sealing rings, resistant to diesel swelling and high/low temperatures, layer-by-layer isolating the combustion chamber gas and the high-pressure oil chamber, preventing high-temperature gas from abrading the nozzle and diesel from leaking out through the assembly gap.
White-milled side integrated waterproof electronic control connector, stable signal transmission and corrosion resistance
Side-mounted white-sealed electronic control connector, equipped with dust-proof and waterproof rubber rings, isolating the engine compartment moisture, diesel oil, and gas, avoiding short circuits and signal loss, with the electronic control engagement force calibrated, ensuring no delay or jamming during fuel injection.
Thickened and reinforced high-temperature reset spring, uniform and stable fuel injection stroke
Thickened rear alloy high-pressure reset spring, uniform spring force calibration, consistent rebound force each time, minimal difference in fuel injection volume for each cylinder, smooth engine operation, and reduced vibration and black smoke emissions.
Precise micro-hole atomizing nozzle at the front end, fully combustible and reducing carbon deposit loss
Head with multiple micro-holes of hard alloy nozzle, fine and uniform fuel atomization particles under high-pressure fuel, matching large-displacement combustion chambers for full combustion, significantly reducing carbon accumulation in the cylinder, and reducing fuel consumption.
Complete factory bench calibration, no need for secondary debugging when installed
Each injector is independently tested for fuel injection pressure, flow rate, and atomization effect, with unified parameters and standards. After replacement, the equipment can quickly restore stable power output, significantly reducing maintenance time.
