Description
Product Overview
0432191253 The mechanical fuel injector is a core component for direct injection pumps without electronic control. It achieves fuel atomization by opening the internal needle valve with the oil pressure output by the piston. After long-term field operations, the sealing surface of the needle valve and the sealing parts may wear out, leading to dripping fuel combustion, power loss, and increased fuel consumption. The entire fuel injector comes with a complete set of sealing accessories. The entire machine can be repaired by replacing the oil circuit fault once, suitable for maintenance and overhaul of light-duty freight trucks, agricultural tractors, and small fixed-duty diesel generators.
Unique core features of the single product
L-shaped lateral threaded fuel inlet, suitable for narrow cylinder head space
Horizontal bent fuel inlet thread structure, suitable for compact cylinder head internal pipeline layout, avoiding pipeline bending and compression; the threaded end head is pre-installed with a transparent dust-proof protective cap, which can isolate dust and impurities during storage and transportation, preventing the needle valve from getting stuck.
Segmented black hardened long shaft valve body, resistant to high pressure and wear
The valve body is multi-segmentally machined and hardened, with a surface anti-corrosion and oil-resistant coating. The layers share the high-pressure fuel impact, and it is less likely to deform or leak under long-term high-temperature conditions. There is no carbon deposit or oil leakage at the joint of the valve body.
Front end copper sealing gasket, high-pressure sealing without pressure loss
The integrated high-temperature-resistant copper gasket at the root of the needle valve, after assembly, closely adheres to the cylinder head installation surface, filling the assembly gap, and preventing high-pressure fuel from leaking from the installation position, maintaining stable cylinder internal injection pressure.
Independent metal sealing gasket for matching, one-step repair for maintenance
Each set comes with a dedicated metal flat gasket. The fuel injector can be disassembled and replaced without additional purchase of sealing consumables. The gasket thickness is uniform, and the locking is uniform, avoiding local pressure loss and oil leakage.
Precision micro-hole long needle valve, fully atomized to reduce carbon black smoke
The front end slender multi-micro-hole nozzle, the high-pressure fuel is atomized finely and evenly, the cylinder internal mixture burns fully, reducing black smoke emissions, slowing down the needle valve carbon deposit blockage, and extending the equipment maintenance cycle. Applicable scenarios
Suitable for light-duty diesel trucks, agricultural tractors, small wheeled loaders, mobile diesel generators, and various mechanical diesel fuel supply equipment for maintenance in fields and construction sites under high and low temperatures, with heavy dust. Applicable to mechanical diesel power equipment without electronic control in fields and construction sites with multiple loads.
