Description
Product Overview
The fuel injector is a key component for atomization and injection in diesel engines. Under high pressure, the fuel flows through the needle valve and the nozzle to form fine oil mist, ensuring complete combustion of fuel in the cylinder. Under long-term conditions of high cabin temperature and impure diesel washing, the needle valve sealing surface wears out and the nozzle gets clogged, resulting in poor atomization, fuel dripping, engine power loss, and excessive black smoke in the exhaust. This product is an integrated precision fuel injector that undergoes comprehensive testing for high-pressure sealing and uniform atomization at the factory. The dimensions are standardized, and disassembly and assembly do not require grinding for compatibility. It is suitable for maintenance of fuel injectors for light trucks, agricultural machinery, and small construction machinery.
Unique core advantages of this product
The widened flange is an integrated base, ensuring stable assembly without deviation.
The widened top step flange limit platform precisely positions the fuel injector housing, preventing skewing and shifting under long-term vehicle vibration, maintaining the coaxiality of the needle valve, and avoiding single-sided wear and uneven atomization in each cylinder.
The center-long precision needle valve locks the oil and prevents leakage.
The built-in longened hardened needle valve fits micro-metrically with the valve seat for sealing, completely cutting off the oil circuit at the end of fuel injection, preventing continuous fuel dripping into the cylinder and accumulating carbon deposits when the engine is stopped, and improving difficulties in cold start and black smoke emissions at idle.
The overall nitrided hardened alloy steel is wear-resistant and resistant to high pressure, and is less likely to be scratched or deformed under long-term diesel and impurity washing.
The entire fuel injector is processed by high-hardness alloy steel, with surface nitriding hardening and mirror-polished grinding. It is less likely to develop scratches or deformations under long-term high-pressure diesel and impurity washing, and the nozzle diameter remains stable over time, significantly extending the service life of the component.
The outer wall is engraved with part numbers for clear model identification and wear resistance.
The side wall of the flange is permanently engraved with the part number 093400-5320, resistant to diesel soaking, wiping wear, making it intuitive for maintenance, inventory, model verification, and effectively avoiding incorrect installation and rework issues.
The micro-precision high-accuracy fuel nozzle is processed with a mirror surface micro-hole grinding process, ensuring uniform and fine oil mist particles, which are evenly distributed and small, allowing for thorough combustion of the mixture in the cylinder, reducing fuel consumption, and minimizing carbon deposits in the cylinder and exhaust pollutants emissions. Applicable scenarios
This product is suitable for light-duty diesel trucks, agricultural tractors, small wheeled loaders, and small stationary diesel generators equipped with mechanical direct injection fuel supply systems. It is applicable for short-distance urban transportation, field farming, light-load construction sites, and small-sized mechanical diesel engines operating in high-temperature, high-dust, and variable temperature and humidity conditions.
