Description
Product Overview
0432231778 This mechanical fuel injector is suitable for non-electrically controlled inline diesel engines. It relies on the high-pressure diesel from the oil pump to push the internal needle valve to complete the atomization and injection. In long-term outdoor conditions with high dust content and varying temperatures, the needle valve's sealing surface may wear out and the sealing components may age, which can lead to dripping fuel combustion, power loss, and increased fuel consumption. This product is a complete finished assembly. It has been calibrated for fuel injection parameters upon leaving the factory. The entire machine can be replaced to repair the oil circuit fault in one go. It is suitable for light-duty freight trucks, agricultural tractors, small loaders, mobile diesel generator sets, and maintenance and overhaul of large-scale equipment.
Unique features of the individual product
Single-hole standard oil inlet thread on the side, no interference during pipe assembly
Standard high-pressure oil inlet thread holes reserved on the middle section of the valve body, suitable for direct connection installation of inline oil pumps with high-pressure oil pipes, with regular pipeline layout without compression or bending; the threaded ends are equipped with transparent plastic dust-proof plugs to isolate sand, dust, and impurities during storage and transportation, avoiding valve core jamming and failure.
Integrated elongated blackened hardened valve body, resistant to high pressure and corrosion
The entire alloy steel is formed by integral turning, with a blackened anti-rust and oil-resistant coating on the surface, and a multi-layer sealing structure. It can withstand high-pressure fuel impact for a long time, and is not prone to deformation, oil leakage, or carbon buildup in the engine compartment under high-temperature conditions, significantly extending the service life.
Double transparent dust-proof protection plugs at both ends, providing comprehensive protection for precision components
Both the nozzle tip and the rear end oil inlet thread are equipped with transparent plastic protective covers. During transportation and storage, they isolate impacts, dust, and prevent the precision needle valve from being scratched or the thread teeth from being damaged, reducing the probability of installation faults.
Locking and positioning screws at the middle section, ensuring the stability and non-loosening of the valve body structure
The middle section of the valve body is equipped with positioning locking screws to fix the internal needle valve components. Under long-term engine vibration conditions, the internal parts will not shift or loosen, ensuring constant fuel injection pressure and eliminating power stalling and idle jitter problems.
Precise micro-hole atomizing needle valve, ensuring complete combustion and reducing carbon black smoke
The front end has a slender multi-micro-hole fuel injection nozzle, with fine and uniform fuel atomization particles from high-pressure fuel. The mixture in the cylinder is fully burned, effectively reducing black smoke emissions, slowing down the accumulation of carbon deposits in the nozzle, and extending the equipment maintenance cycle.
Application scenarios
Suitable for light-duty diesel trucks, agricultural tractors, small wheeled loaders, mobile diesel generator sets, and mechanical diesel power equipment for high-temperature and dusty conditions in urban short-distance transportation, field farming, construction sites with light loads, etc.
