Description
Product Overview
0432193666 The mechanical fuel injector is a core fuel injection component for direct injection diesel engines. It pumps high-pressure diesel oil from the oil pump to open the needle valve for fuel injection. After long-term operations in dusty fields or construction sites, the needle valve sealing surface may wear out and the sealing components may age, resulting in dripping fuel combustion, reduced power, and increased fuel consumption. The complete integrated finished product is manufactured and shipped directly, without the need for secondary adjustment. It can directly fix the fuel system faults and is suitable for maintenance and overhaul of light freight vehicles, agricultural tractors, small diesel generators, and light loaders.
Unique core features of the single product
Side straight hole oil inlet thread design, simple pipeline layout without interference
The middle section of the valve body has a standard oil inlet thread hole reserved on one side, suitable for direct connection assembly with the straight high-pressure oil pipe of the direct injection oil pump. The pipeline layout is neat without bends or compressions, the thread end face is flat, and the sealing is tight and not prone to leakage.
Segmented blackening and hardening of the extended valve body, wear-resistant, corrosion-resistant, and resistant to high pressure
The entire alloy steel is machined as a whole in segments, with blackening treatment on the surface to prevent rust and oil resistance, and a multi-layer sealing structure. Under long-term high-pressure fuel impact and high-temperature conditions in the engine compartment, it is less likely to deform, leak, or accumulate carbon, and has a longer service life.
The front end of the nozzle has an integrated copper sealing gasket, which is stable in sealing lock pressure
A high-temperature-resistant purple copper gasket is pre-installed at the root of the needle valve, and after assembly, it closely adheres to the installation plane of the cylinder head, filling the small gaps during assembly, completely blocking the leakage of high-pressure fuel, maintaining the injection pressure in the cylinder, and avoiding power loss due to pressure relief.
The pressure adjustment is unified for the entire set at the time of factory production, and the multi-cylinder engines work synchronously without jitter
Products of the same batch are uniformly adjusted for fuel injection pressure and atomization standards. After replacing the fuel injection system of multiple cylinders, the consistency of fuel injection in each cylinder is high, the idle speed is stable, the acceleration power is balanced, and the problems of single-cylinder power deficiency, vehicle shaking, and black smoke from the exhaust are eliminated.
The long extension needle valve with precise micro holes, fully fuel atomization and reduces carbon accumulation
The front end of the slender multi-micro-hole fuel injector nozzle cuts the high-pressure fuel into fine oil mist particles, allowing for complete combustion of the mixture in the cylinder, reducing carbon formation and black smoke emissions, and extending the maintenance period of the fuel injector. Applicable scenarios
Light-duty diesel trucks, agricultural tractors, small wheeled loaders, mobile diesel generators, are suitable for short-distance urban transportation, field farming, light-load construction site operations, etc. They are high-temperature and high-pollution mechanical diesel-powered equipment for maintenance in various environments.
