Description
Product Overview
DLLA146PN218 belongs to the PN series of diesel fuel injectors' components and is a core precision part of the engine fuel injection system. It corresponds to the component number 105017-2180 and can be replaced and repaired by matching the same specification injector assembly. The product is produced through standardized precision molding, with stable size tolerances, which can be adapted to multiple models of the same specification diesel power equipment. It solves the problems of aging and wear of the fuel injection components, and abnormal equipment operation caused by these issues in one step.
Product material and process
The overall material is high-speed steel, and it is combined with vacuum quenching and heat treatment processes. The finished product has uniform hardness and can withstand the long-term high-temperature and high-pressure working environment of the engine. It has good tolerance to diesel impurities erosion and medium corrosion, and can stably extend the service life of the parts.
The nozzle head adopts a micro-hole precision grinding process, with uniform spray hole angles and diameters, and the fuel spray form is uniform and gentle, facilitating the thorough mixing and combustion of oil and gas.
Practical performance advantages
Stable atomization performance
The fine spray hole design reduces fuel particles, improves the combustion state in the cylinder, helps stabilize the engine idle operation, and reduces carbon buildup.
Good sealing and pressure-bearing performance
Each finished product undergoes sealingity and high-pressure atomization tests, reducing the probability of oil leakage and pressure relief under high-pressure conditions, maintaining stable fuel supply pressure.
Standard universal assembly dimensions
The overall shape and installation positioning dimensions are in line with the corresponding injector assembly position, no additional grinding or modification is required, and direct replacement of the old part can reduce maintenance time.
Suitable for multi-scenario maintenance needs
Each single component is independently packaged for protection, which is not prone to damage from storage impacts, and supports sample purchase, batch bulk ordering, and is suitable for various procurement needs such as offline repair stores, fleet maintenance, cross-border auto parts distribution, etc. Scope of Application
Compatible with the maintenance and replacement of fuel injectors for 4-cylinder diesel-powered light-duty transportation vehicles, small construction machinery, fixed diesel generators and other equipment; applicable for after-sales repair parts, inventory stocking of spare parts, and export auto parts wholesale channels.
Quality Inspection Description
All fuel injectors are completed with multiple layers of performance tests upon leaving the factory, including sealingity pressure tests, atomization form tests, and size tolerance inspections, to uniformly control product stability; neutral independent packaging is available, and long-term stable supply is supported.
