Description
Product Overview
The electronically controlled common rail injector receives signals from the vehicle's electronic control unit, precisely controlling the timing and volume of high-pressure fuel injection to ensure complete combustion of fuel in the cylinders. Over time, internal valve cores may wear, electromagnetic coils may age, and sealing components may leak, resulting in poor atomization, dripping after combustion, and power loss. This product is a complete injector assembly, with all atomization effects, injection pressure, and high-pressure sealingity fully tested upon leaving the factory. The entire machine can be replaced without disassembly and calibration. It is suitable for the major overhaul and replacement of the fuel injection systems of light freight vehicles, light passenger cars, and small construction machinery common rail diesel equipment.
Unique Core Features of the Individual Product
Segmented and lengthened mirror stainless steel valve stem, resistant to high pressure and wear, and not prone to deformation
The main valve stem is made of multi-segment mirror-surfaced precision-ground stainless steel material, with a surface hardened and polished treatment. It is not prone to wear or deformation under the long-term impact of common rail high-pressure fuel, and the valve needle fitting clearance is precise and stable, eliminating the problems of dripping and poor atomization.
Side-mounted integrated black snap-on electronic waterproof connector, stable signal transmission
The black plastic-sealed electronic connector on the left side of the valve body, with multiple layers of waterproof and dust-proof rubber rings inside, isolating the engine compartment's engine oil, water vapor, and dust erosion. The pins are not prone to oxidation and false connection under vehicle jolting conditions, and the electronic fuel injection signal response has no delay.
Top-mounted independent high-pressure fuel inlet interface, pre-installed transparent dust-proof protective plug
The standard high-pressure fuel screw thread connector on the top of the valve body, with factory-matched transparent plastic dust-proof plug. During storage and transportation, it prevents sand and impurities from entering the internal valve core, avoiding installation jamming and failure.
The entire nozzle end is fully wrapped with a transparent dust-proof protection sleeve, providing precise micro-holes protection
The nozzle tip is equipped with a transparent plastic protection cap. During transportation and storage, it isolates the nozzle from磕碰划伤， protecting the precise micro-holes of the nozzle， reducing the failure rate of installation and preventing nozzle holes from clogging.
High-precision micro-hole atomization nozzle， ensuring complete fuel combustion and reducing carbon deposits and black smoke
The front multi-micro-hole precision nozzle cuts the high-pressure fuel into fine and uniform oil mist particles. The mixture in the cylinder is fully combusted， reducing carbon deposits accumulation and black smoke emissions， and extending the equipment maintenance cycle. Applicable scenarios
Suitable for light-duty diesel trucks, light-duty passenger vehicles, small wheeled loaders, and mobile diesel generators. It is applicable for high-pollution, high-low temperature alternating maintenance of small-sized electronically controlled common rail diesel power equipment used in urban short-distance transportation and construction sites with light loads.
