Description
Product Overview
The fuel injector is the core component for fuel atomization. Under high pressure, the fuel passes through the needle valve and the spray hole to be fragmented into fine oil mist, ensuring complete combustion in the cylinder. Over time, due to the erosion of diesel impurities and the high-temperature working conditions, the sealing surface of the needle valve may wear out, and the spray hole may get clogged. This can lead to poor atomization, engine shutdown with dripping oil, reduced engine power, and excessive black smoke. This product is an integrated precision fuel injector that is formed as a whole. It undergoes factory testing for high-pressure sealing and comprehensive atomization performance. The dimensions are standardized, and it can be disassembled and directly replaced, suitable for maintenance of fuel injectors for light-duty trucks, agricultural machinery, and small construction machinery.
Unique core advantages of this product
The stepped flange integrated base ensures precise assembly and no offset
The widened top stepped flange limit platform firmly holds the fuel injector housing when installed, preventing the equipment from tilting or shifting during long-term vibration operations. The needle valve maintains a stable coaxiality, avoiding single-sided wear and uneven atomization.
The center-long precision needle valve with a sealed lock oil function prevents dripping
The internally added longened hardened needle valve and valve seat have a micrometer-level fit, locking the oil path completely upon closure, preventing fuel from dripping into the cylinder during engine shutdown and forming carbon deposits, and improving difficulties in cold start and black smoke during idle operation.
The overall nitrided hardened alloy steel is wear-resistant and resistant to high pressure, reducing the risk of scratching during long-term diesel and impurity erosion.
The entire fuel injector is processed as a whole using high-hardness alloy steel. The surface is finely ground through nitriding treatment, making it resistant to scratches and deformation from long-term high-pressure diesel and impurity erosion. The spray hole size remains stable for a long time, significantly extending the service life.
The outer wall is laser-engraved with the part number for clear model identification and resistance to wear from diesel immersion, wiping, and abrasion. The laser permanently engraves the 23620-19105 part code on the flange side, facilitating intuitive maintenance, inventory preparation, model verification, and avoiding incorrect installation and rework.
The micro-precision fuel injection holes are precisely machined, ensuring fine fuel atomization for thorough combustion
The micro-holes at the head are processed using high-precision micro-hole grinding technology, resulting in uniform and fine oil droplets. The mixture in the cylinder burns thoroughly, reducing fuel consumption and minimizing carbon deposits and exhaust pollutant emissions in the cylinder. 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.
