Description
Product Overview
The fuel injector is the final precision component for fuel atomization. High-pressure fuel passes through the internal needle valve and is cut by the front micro-hole to form fine oil mist, which mixes with the air in the cylinder and burns thoroughly. Under long-term high-temperature and impure diesel erosion conditions, the injection holes may get clogged, and the sealing surface of the needle valve may wear out, resulting in poor atomization, engine shutdown with dripping oil, weak power in a single cylinder, black smoke emission from the engine, and increased fuel consumption. This product is an integrated precision fuel injector that is completed with high-pressure holding and atomization flow detection upon leaving the factory. The size specifications are uniform, and disassembly and assembly do not require grinding for adaptation. It is suitable for maintenance of agricultural machinery, small and medium-sized trucks, and construction machinery fuel injectors.
Unique Core Advantages of the Single Product
Conical gradual integrated valve body, smooth flow and stable oil pressure
It adopts an upper-wide and lower-narrow conical gradual structure. The high-pressure fuel flows downward smoothly without turbulence, the oil circuit pressure loss is small, the injection pressure is stable throughout the process, and it ensures uniform atomization effect every time.
The top is permanently engraved with the part number for easy matching and less misinstallation
The upper end of the valve body is laser-etched with the DL-150P224 model code. It is resistant to diesel soaking, wiping wear, and is intuitive for maintenance, spare parts, and component verification, effectively avoiding model confusion and rework.
Fine micro-hole mirror surface polishing injection holes, fine atomization and full combustion
The front injection micro-hole is processed by mirror surface grinding, with no burrs on the hole wall. The high-pressure fuel is cut into uniform and fine oil mist, and the mixture in the cylinder is fully burned, reducing carbon formation, and lowering black smoke and fuel consumption from the exhaust.
Overall nitrided hardened alloy steel, wear-resistant and resistant to impurities, not prone to scratches
The entire fuel injector is processed by high-hardness alloy steel, with surface nitrided hardening treatment. The needle valve and valve seat are precisely matched at the micrometer level. Long-term hard impurity diesel erosion does not cause scratches, and the oil is locked for a long time to prevent shutdown and dripping.
Standard flange limit step, precise assembly and no leakage
The upper integrated limit flange step is precisely aligned with the fuel injector housing during assembly, and after matching with the sealing gasket, multiple layers of barriers prevent the leakage of high-pressure fuel, ensuring stable fuel injection pressure output. Applicable scenarios
This product is suitable for agricultural tractors with mechanical direct injection fuel supply system, light-duty freight diesel vehicles, small wheeled loaders, fixed diesel generator sets. It is applicable for agricultural field operations, light-load construction sites, and small-sized outdoor machinery diesel engines with high temperature, high humidity and high dust. It is suitable for major overhauls of fuel injectors of such diesel engines.
