Description
Product Overview
The electromagnetic valve assembly is installed on the upper part of the common rail injector, receiving precise control signals from the ECU to precisely open and close the internal needle valve, thereby regulating the fuel injection volume and timing. Under long-term conditions of high-temperature vibrations in the engine compartment, erosion by diesel oil and gas, and frequent on-off shock conditions, oxidation of the pins, jamming of the valve core, aging of the insulation layer, and deformation of the housing may occur, resulting in poor signal contact, incorrect fuel injection timing, single-cylinder shutdown, engine power loss, severe idling vibration, difficulty in starting cold engines, and significant increase in fuel consumption. This product is an integrated precision electromagnetic valve assembly that undergoes comprehensive testing for high-pressure sealing, power-on response speed, and conductive stability upon leaving the factory. The housing assembly dimensions are standardized, and disassembly and assembly do not require grinding to fit, making it suitable for maintenance of common rail injectors of heavy-duty trucks, mining engineering machinery, and large-power diesel generators.
Unique Core Advantages of the Individual Product
Multi-level stepped metal housing, no loosening during assembly
The housing is made of multi-segment ring-shaped stepped structure, with a precisely machined positioning ring on the outer wall, which fits precisely into the limit slot of the injector after installation. It will not shift or loosen under driving vibrations, isolating the oil circuit from the electrical circuit to maintain the same assembly coaxiality over the long term.
Gold-plated conductive pins at the tail, stable conductivity, resistant to oxidation and corrosion
The conductive contacts adopt a thickened gold-plated process to resist diesel volatile oil and gas, high-temperature oxidation and rusting, reducing contact resistance, ensuring synchronous execution of fuel injection instructions, and eliminating cylinder shutdown and intermittent fuel cut-off problems.
Built-in high-temperature resistant insulation buffer rubber sleeve, isolating oil and circuit interference
The integrated rubber insulation buffer layer wraps the internal coil, isolating the circuit from diesel and high-temperature water vapor erosion, buffering the stress loss caused by engine vibrations, avoiding coil short-circuit, leakage, and burnout, and extending the service life of the electromagnetic valve.
Split-side split-type locking limit slots, convenient disassembly and precise positioning
The housing is reserved with split-type locking slots, allowing maintenance and disassembly tools to precisely clamp, without squeezing and damaging the conductive pins. During assembly, it can be one-click aligned and locked, reducing the difficulty of maintenance operations and reducing the human-induced damage to components.
High-precision built-in electromagnetic valve core, rapid and uniform opening and closing response
The internal valve core uses a precision ground alloy material, with consistent electromagnetic attraction and reset speeds, stable cylinder fuel injection timing difference control, balanced atomization and combustion, effectively reducing black smoke emissions and optimizing fuel utilization.
High-strength alloy housing, resistant to high temperatures and deformation
The housing is made of quenched alloy steel processed as a whole, capable of withstanding continuous high-temperature conditions in the engine compartment and high-pressure diesel immersion, and is not prone to cracking or deforming under long-term heavy-duty operation, suitable for mining areas, long-distance freight transportation 24-hour continuous operation conditions. Applicable scenarios
This product is suitable for medium and heavy-duty long-distance freight trucks with high-pressure common rail fuel supply systems, large mining excavators, heavy-duty wheeled loaders, fixed high-power diesel generator sets. It is applicable to mining areas and construction sites for 24-hour full-load operation under high temperature and high vibration conditions. It is suitable for the overhaul of large electronic control diesel engine fuel injectors in harsh environments.
