Zhonglutong M0502P147 Common Rail Injector Nozzle Assembly

The M0502P147 is a piezoelectric common rail injector nozzle designed for Siemens VDO (Continental) fuel injection systems. It serves as a critical wear component within the injector assembly, responsible for final fuel atomization under high pressure. This nozzle model corresponds to injector assembly part numbers 5WS40087 and A2C59511606. It is engineered for the Renault K9K 1.5 dCi engine platform, widely deployed across Renault, Nissan, Dacia, and Mercedes-Benz light commercial and passenger vehicle ranges. The nozzle features a multi-hole spray pattern optimized for the K9K combustion chamber geometry. Constructed from high-speed tool steel with hardened needle and body seats, the component withstands peak rail pressures exceeding 1,800 bar. Manufacturing tolerances adhere to ISO 9001:2015 quality management standards, ensuring consistent flow rates and spray cone angles matching original equipment parameters. The nozzle is supplied as a standalone replacement part for injector refurbishment by authorized diesel specialists.
