Description
Product Overview
The electronically controlled common rail injector receives signals from the vehicle's electronic control unit, precisely controlling the timing, volume, and atomization effect of high-pressure fuel injection, ensuring complete combustion of fuel in the cylinders. Under long-term mining heavy-load, high-temperature, and diesel impurity erosion conditions, internal valve cores may wear, electromagnetic coils may age, and nozzles may get clogged, resulting in poor atomization, post-dripping combustion, and limited power. This product is a complete integrated injector. It undergoes comprehensive testing for atomization performance, high-pressure sealing, and electronic control response speed upon leaving the factory. It comes with a matching copper gasket that does not require additional purchase of sealing components. It is suitable for maintenance and replacement of large excavators, heavy-duty loaders, and high-power diesel generators.
Unique Core Features of the Single Product
Black integrated forged valve body, resistant to high temperatures and impacts, and not prone to deformation
The main body is made of high-strength forged alloy steel valve body, with a black oil-resistant and anti-corrosion coating on the surface. It can withstand long-term high-temperature and vibration impact of the cylinder head, not cracking or leaking, and is suitable for heavy equipment operating continuously for 24 hours under full-load conditions.
Vertical waterproof electronic control connector at the tail, stable signal transmission and anti-interference
The end of the valve body is a vertically sealed plastic connector, with multiple layers of waterproof and dust-proof rubber rings inside, isolating the erosion of engine oil, water vapor, and dust. The pins are not prone to oxidation and false connection under equipment vibration conditions, and the fuel injection signal response is without delay or signal drift.
Segmented mirror stainless steel valve stem, wear-resistant under high pressure without dripping or leaking
The internal longer segmented mirror precision ground stainless steel valve stem is treated with overall hardening and polishing. It can withstand the high-pressure fuel from the common rail for a long time without scratching or wearing, and the valve core sealing gap is precise, eliminating the problem of shutdown dripping and carbon accumulation in the cylinder.
Transparent plastic spray nozzle protection sleeve at the front end, protecting precise spray holes during transportation
A transparent protective sleeve is pre-installed at the tip of the spray nozzle. During storage and transportation, it isolates磕碰磕碰， dust scratches， and micro-hole spray holes from being damaged， avoiding abnormal atomization and failure of the nozzle after installation.
Matching thickened copper sealing gasket， eliminating leakage of cylinder head seal
Each set comes with a thickened copper gasket， with a soft and high-temperature-resistant texture. After compression， it fills the gap between the cylinder head and the injector installation， providing double barriers against high-pressure fuel leakage， stabilizing the common rail oil pressure， and reducing oil accumulation. Applicable scenarios
It is suitable for large mining excavators, heavy-duty wheeled loaders, heavy-duty diesel generators, and large engineering equipment that are equipped with the corresponding common rail system. It is applicable to heavy-duty diesel power injection systems in mining areas and construction sites for full-load operation under all weather conditions, including high temperatures and high dust levels.
