Description
Product Overview
The electronically controlled common rail injector receives signals from the electronic control unit, precisely controlling the timing and volume of high-pressure fuel injection to ensure complete combustion of fuel in the cylinder. Over time, internal valve cores may wear, coils may age, and sealing components may leak, resulting in poor atomization, dripping after combustion, and power loss. This complete injector assembly undergoes a full set of tests for atomization, injection pressure, and sealing at the factory. The entire machine can be replaced without disassembly and calibration. It is suitable for major repairs and replacements of fuel injection systems in light freight vehicles, small construction machinery, and agricultural common rail diesel equipment.
Unique features of this single product
Segmented and lengthened stainless steel valve stem, resistant to high pressure and wear without deformation
The main valve stem is made of segmented precision-ground stainless steel material, with a mirror-hardened surface. It is less likely to wear or deform under the long-term impact of common rail high-pressure fuel, and the valve stem gap is precise and stable, eliminating the problems of dripping and poor atomization.
Black side-mounted electrical control waterproof plug, stable signal transmission
The upper side-mounted integrated black plastic sealed electrical control connector, with multiple layers of waterproof and dust-proof rubber rings inside, isolating the engine compartment from engine oil, water vapor, and dust erosion. The pins do not oxidize or short-circuit under vehicle jolting conditions, and the response of the electronic control fuel injection signal is without delay.
Top independent high-pressure fuel inlet connector, with a dust-proof protection plug
The standard high-pressure fuel screw interface at the top of the valve body, pre-installed with a transparent plastic dust-proof plug, preventing sand, impurities, and other substances from entering the internal valve core during storage and transportation, avoiding installation jamming and failure.
Yellow brass sealing gasket at the front end, high-pressure sealing at the cylinder head installation position without oil leakage
A high-temperature-resistant brass sealing ring is pre-installed at the tip of the nozzle, and after being installed in the cylinder head, it closely adheres to the installation plane, filling the small gaps for assembly, blocking high-pressure fuel leakage, and stabilizing the injection pressure in the cylinder to prevent insufficient power during pressure relief.
Full coverage transparent dust-proof protection sleeves at both ends, providing comprehensive protection for the precise nozzle
Transparent plastic protective caps are equipped at both the nozzle tip and the return oil interface, protecting the precise micro-hole nozzle from磕碰 and scratches during transportation and storage， reducing the failure rate of installation. Applicable scenarios
Suitable for light-duty diesel trucks, agricultural tractors, small wheeled loaders, mobile diesel generators, and are applicable for short-distance urban transportation, field farming, construction site light-load operations, etc. They are suitable for maintenance of small-sized electrically controlled common rail diesel power equipment in high-pollution, alternating high and low temperatures environments.
