Description
Product Overview
Mechanical fuel injectors rely on the oil pump to deliver high-pressure fuel to push open the internal needle valve, achieving atomized injection. The built-in spring controls the opening pressure, stabilizing the single injection volume. They are widely compatible with light-duty trucks, small construction machinery, agricultural machinery, and small generator sets for diesel power. Under long-term conditions of high cabin temperature and diesel impurities erosion, the needle valve sealing surface may wear, the spring elasticity may decline, and the nozzle may accumulate carbon and get clogged, resulting in poor atomization, internal fuel leakage, power decline, and excessive black smoke. This complete integrated fuel injector product has undergone comprehensive testing for opening pressure, high-pressure sealing, and atomization performance upon leaving the factory. The entire machine can be replaced without disassembling the internal precision components, and is suitable for maintenance of small-scale diesel equipment injection systems.
Unique core advantages of this single product
Segmental chrome alloy steel valve body, preventing rust and wear, reducing internal leakage
The valve body is processed as a multi-stage stepped alloy steel unit, with a chrome plating surface for rust prevention, overall hardening and polishing. The gap between the needle valve and the valve seat is extremely precise, and it is not prone to scratching and wear due to long-term high-pressure diesel erosion, preventing internal leakage of oil pressure, and maintaining stable injection pressure.
The middle hexagonal locking positioning platform, convenient for assembly, disassembly, and adjustment
The integrated hexagonal locking platform in the middle of the valve body is suitable for standard wrenches for assembly and disassembly. The tightening torque is controllable, and when installed in the cylinder head, it is precisely positioned without skewing. It is not prone to loosening and seepage under long-term vehicle vibration and shaking, and the sealing effect is long-lasting.
Transparent plastic dust-proof protection caps at both ends, providing protection throughout storage and transportation
Transparent protection caps are provided at the oil inlet thread end and the front nozzle, preventing dust,磕碰， and scratches on the precise threads and spray holes. This avoids impurities blocking the parts during storage and transportation and prevents the nozzle from deforming. The product can be directly assembled upon arrival.
Built-in standard pressure regulating spring， stable and uniform opening pressure
The internal is equipped with a high-temperature tempering reset pressure regulating spring， with uniform spring force. It is not prone to fatigue deformation under long-term reciprocating impact， ensuring consistent needle valve opening and closing times， balanced fuel injection volume for each cylinder， and eliminating idle vibration and single-cylinder performance weakness problems.
Fine conical front spray holes， fine fuel atomization for complete combustion
The conical precise spray hole structure at the front end cuts the high-pressure fuel into uniform and fine oil droplets. The mixture in the cylinder is fully burned， reducing carbon buildup in the cylinder， lowering fuel consumption， and extending the maintenance cycle of the engine. Applicable scenarios
This product is suitable for light-duty diesel trucks with mechanical direct injection systems, small wheeled excavators, agricultural tractors, and small fixed diesel generator sets. It is applicable for short-distance urban transportation, field farming, light-load construction sites, and maintenance of small-sized diesel injection systems in high-temperature, high-dust, and low-load environments.
