Description
Product Overview
The electromagnetic coil is installed at the tail of the injector and is energized to generate electromagnetic suction to lift the internal needle valve, opening the high-pressure oil passage to achieve fuel injection. After long-term exposure to high cabin temperatures, diesel vapor corrosion, and frequent power-on operation, the insulation layer of the coil is damaged and short-circuited, and the magnetic force weakens. This can lead to single-cylinder non-functioning, weak acceleration, severe idling vibration, black exhaust smoke, frequent engine fault codes popping up. This product has standardized inner diameter, snap-fit dimensions, and electromagnetic suction parameters of the coil. The coil can be replaced separately during maintenance, eliminating the need to replace the entire injector, thereby reducing maintenance costs and being suitable for the maintenance of common rail injectors for light trucks, diesel buses, and small excavators.
Core advantages of this product:
The high-temperature black insulating plastic enclosure isolates oil, water, and steam short circuits.
The coil is encapsulated in an overall high-temperature-resistant engineering plastic, which isolates diesel oil, gas, and cabin water vapor erosion. The insulation layer of the coil is less likely to age and crack under high-temperature conditions, effectively avoiding short circuits and burnout.
The metal nameplate engraved with codes + QR code enables quick identification of the model.
The metal sticker is engraved with the 28346624 part number and the identification QR code, which is resistant to diesel soaking and wiping without the characters falling off. It is convenient for warehouse storage and maintenance verification when distinguishing specifications during model comparison, avoiding incorrect installation and resulting in disorder in fuel injection timing.
The one-piece molded snap-fit installation bracket is firmly and securely assembled without loosening.
The matching U-shaped snap-fit bracket of the same material has precise positioning dimensions. After wrapping the coil, it fits tightly with the injector housing. During vehicle vibration conditions, it will not shift or loosen, ensuring stable output of electromagnetic suction.
High-precision built-in electromagnetic winding, with sensitive and uniform opening and closing response.
The internal neatly wound high-temperature-resistant enameled winding is standardized for electromagnetic suction. It quickly opens the needle valve upon power-on and closes immediately upon power-off, without issues of insufficient suction or delayed fuel injection. The consistency of fuel injection in each cylinder is good.
Anti-aging sealing structure, long-lasting adaptation to complex conditions.
The sealing treatment at both ends of the coil is reinforced to prevent fine diesel impurities from entering the winding inside. It has a longer service life in dusty and humid environments in fields and construction sites, reducing the need for repeated maintenance.
Split replaceable design, lower maintenance costs.
Supports the separate replacement of the coil without replacing the entire injector assembly. This significantly reduces the customer's maintenance costs. The disassembly and assembly operation is simple, and no professional grinding equipment is required. List of Accessories
