Description
Product Overview
The common rail injector component is the core component of the electronically controlled fuel injector for fuel atomization. The internal needle valve and the injector housing are precisely matched, and the high-pressure fuel passes through the front micro-holes to form a uniform oil mist. After long-term exposure to high temperatures in the engine compartment and erosion by diesel impurities, the sealing surface may wear and the spray holes may get clogged, resulting in poor atomization, dripping after combustion, engine torque limitation, and fault indicator alarms. This product is manufactured with a complete set of needle valves and injectors that are precisely ground together, completing the atomization and high-pressure sealingity tests. There is no need for on-site secondary grinding. It is suitable for major repairs and replacements of injectors in light trucks, construction machinery, agricultural common rail diesel equipment.
Unique Core Features of the Individual Product
Segmented stepped hardened alloy steel body, wear-resistant and unaffected by high pressure without deformation
Integrated high hardness alloy steel is machined as a whole, with segmented stepped positioning structure, overall quenching + mirror polishing treatment. It can withstand the long-term high-pressure fuel erosion without being scratched or deformed, ensuring a stable needle valve sealing gap and preventing dripping and pressure relief.
Front multi-micro-hole precise spray head, fine fuel atomization for complete combustion
Standard precise spray holes at the head, uniformly ground and machined in diameter, the high-pressure fuel is cut into fine and uniform oil mist, the mixture in the cylinder is fully burned, reducing carbon buildup, reducing black smoke emissions, improving power while reducing fuel consumption.
The outer wall is permanently laser engraved with the part number, making the model identification less prone to wear
The outer circle of the injector is laser etched with the DLLA150P858 model code, resistant to diesel soaking and wiping without the characters falling off, making it intuitive and clear for maintenance inventory, accessory verification, and avoiding incorrect installation and rework.
One-to-one paired grinding processing, with uniform and stable mating clearance
Each needle valve is individually paired ground with the injector housing, ensuring uniform sealing clearance and opening pressure standards. After replacing the injectors in a multi-cylinder set, the fuel injection volume of each cylinder is balanced, eliminating idle jitter, acceleration jolt, and single-cylinder power weakness problems.
High-precision positioning stepped steps, precise assembly alignment without deviation
The middle stepped positioning platform ensures precise limit positioning when installing the injector housing, no deviation or skew during assembly, ensuring the standard injection angle and avoiding uneven fuel injection in the cylinder and severe carbon buildup in certain areas. Applicable scenarios
Suitable for light-duty diesel freight vehicles, small wheeled excavators, agricultural tractors, mobile diesel generators, and are applicable for short-distance urban transportation, field farming, light-load construction sites, and maintenance of small-sized electrically controlled common rail diesel power equipment's fuel injection systems under high temperatures, high humidity and dust conditions.
