Description
Product Overview
The electronically controlled common rail injector receives the vehicle's electronic control signals, precisely controlling the amount and timing of high-pressure fuel injection, ensuring complete combustion of fuel in the cylinders. Under long-term heavy-duty conditions, internal valve cores may wear, seals may age, and atomization holes may get clogged, resulting in dripping fuel combustion, power loss, and excessive exhaust emissions. This product is a complete injector assembly. It undergoes a complete set of tests for atomization effect, injection pressure, and high-pressure sealing at the factory. The entire machine can be replaced without disassembly and debugging. It is suitable for heavy-duty trucks, large construction machinery, and mining loaders with common rail engines for major repairs and replacements.
Unique core features of this product
Segmental hardened stainless steel valve body, high-pressure resistant and not prone to deformation
The main body is made by integrating multiple segments of finely ground alloy steel, with a surface hardened anti-rust treatment. It can withstand the high-pressure fuel flushing from the common rail for a long time. The valve needle has a stable gap, and there will be no valve core sticking, poor atomization, or dripping oil and leakage problems.
Segmented transparent fully encapsulated dust-proof sleeve, providing comprehensive protection for precision components
The valve body is equipped with segmented semi-transparent plastic protective covers, which respectively wrap the valve body and the two sections of the nozzle precision areas. During storage and transportation, it completely isolates dust, bumps, and scratches, avoiding damage to the micro-hole nozzles and precision valve needles, and reducing the probability of installation faults.
Integrated front brass sealing gasket, no oil leakage when installing the cylinder cover with high-pressure locking oil
A pre-installed high-temperature-resistant purple copper sealing ring is installed at the nozzle root, which fits tightly against the plane after being inserted into the cylinder cover installation hole, filling the small assembly gaps, blocking the leakage of high-pressure fuel from the installation position, and maintaining stable cylinder injection pressure, avoiding insufficient power pressure.
Precision multi-micro-hole injector nozzle, fully atomizing fuel to reduce carbon deposits and black smoke
The micro-hole nozzle at the head adopts a mirror grinding process, cutting the high-pressure fuel into fine oil mist particles. The mixture in the cylinder burns fully, reducing carbon deposits and black smoke emissions, and extending the maintenance period.
Uniform factory standard calibration, balanced power output in multiple cylinders without vibration
Products of the same batch are calibrated with the same injection pressure, injection volume, and atomization standards. After the replacement of multiple-cylinder equipment with a complete set, the power output of each cylinder is balanced, eliminating body vibration, acceleration jolts, and single-cylinder power deficiency faults. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, heavy-duty loaders, high-power diesel generators, and heavy-duty diesel power supply systems for mining areas and construction sites that operate continuously at full load under high temperature and high dust conditions for 24 hours.
