Description
Product Overview
The electronically controlled fuel injector relies on the electromagnetic valve to receive the engine's electronic control signals, precisely controlling the timing, volume and frequency of high-pressure fuel injection. It is the core executive component of the common rail power system. Under long-term mining conditions of 24-hour full load, high cabin temperature and impurities from diesel washing, the sealing ring ages and leaks, the internal valve components wear out, and the electromagnetic components age. This can lead to disorder in fuel injection timing, imbalance in each cylinder's work, decline in vehicle power, and a significant increase in fuel consumption. This complete integrated fuel injector is factory-tested for flow matching, high-pressure leakage, and stability in high and low temperatures, and is suitable for major mining excavators, heavy-duty freight trucks, and large power generator sets for the overhaul of their electronic fuel injection systems.
Unique core features of this product
The integrated cast aluminum electromagnetic valve body has strong heat dissipation and is resistant to vibration, and is unlikely to crack.
The upper electromagnetic control housing is integrally cast, with a built-in reinforcing structure, effectively resisting long-term vehicle vibration and shock; the aluminum material has excellent heat conductivity, quickly dissipating the electromagnetic working heat and reducing signal failure faults caused by high temperatures.
Multiple layers of colored layered high-pressure sealing gaskets, multiple layers of barriers to prevent fuel leakage
The fuel injection rod is paired with multi-color oil-resistant high-pressure sealing gaskets, with layered sealing of the oil circuit, resisting the impact of high-pressure fuel and the corrosion of engine oil, and multiple layers of barriers to avoid high-pressure oil leaking from the valve body connection point, stabilizing the output of the rail pressure, and reducing pressure attenuation.
Extruded thick high-strength reset spring, stable and unified injection response
The external matching of thick alloy reset spring, with uniform and long-lasting elasticity, is not prone to softening or deforming under long-term high-frequency reciprocating impact, ensuring consistent opening and closing strokes of each injection, smaller differences in fuel injection volume for each cylinder, and smooth idling without vibration.
Locking-type waterproof electronic control wiring plug, stable interference-free signal transmission
The black plastic injection control connector on the side has a snap-locking structure, with multiple layers of waterproof rubber cores, isolating cabin moisture, oil stains, and electromagnetic interference of the wiring, no false connection of the pins during vehicle bumps, and continuous and uninterrupted transmission of speed and fuel injection signals during operation.
Long conical multi-hole fuel injection end, fine fuel atomization and complete combustion
The front end has an extended conical precision injection head, with multiple groups of fine holes, high-pressure fuel is cut into uniform and fine oil mist, the mixture in the cylinder is fully burned, reducing the generation of carbon deposits in the cylinder, reducing exhaust black smoke and fuel consumption. Applicable scenarios
It is suitable for heavy-duty long-distance freight trucks with electronic control common rail fuel supply system, large mining excavators, heavy-duty loaders, high-power fixed diesel generator sets. It is applicable to mining areas and construction sites for 24-hour continuous full-load operation under high temperature and high dust conditions. It is suitable for major overhaul of heavy-duty diesel engine injection systems.
