Import Diesel Injector Nozzle Dn15s156 — Buy in Bulk from Supplier in China

The Diesel Injector Nozzle DN15S156 is a precision-engineered component designed for direct injection diesel engines, matching the OEM specification for fuel delivery geometry and spray angle. It is manufactured to fit engines requiring the DN15S156 model code, with a nozzle orifice diameter of 0.18 mm and a nominal flow rate of 1.25 ml per stroke at 1500 bar. The body is machined from high-strength chrome-molybdenum steel, heat-treated to resist thermal fatigue under sustained combustion pressures.

This nozzle variant is typically used in medium-duty commercial diesel engines and is compatible with common rail systems operating between 1200 and 1800 bar. Standard industry tolerances for nozzle tip wear are ±0.005 mm, and this unit meets those benchmarks. The internal channel geometry is optimized to reduce carbon buildup, a common failure mode in older injector designs. Surface finish on the needle and seat is ground to Ra ≤ 0.2 µm to ensure tight sealing under cyclic high-pressure conditions.

Buyers include diesel engine rebuilders, fleet maintenance providers, and agricultural equipment distributors serving markets in Southeast Asia and Eastern Europe. The product is supplied in sealed anti-static packaging with individual serial numbering. Minimum order quantities are not specified in the listing; buyers should confirm packaging quantities and lead times directly with the supplier. Trade terms such as FOB Fuzhou or CIF are available upon request, but documentation must be verified prior to shipment.

Chen Chen Diesel Parts Plant is a manufacturer located in Fuzhou, Fujian Province, China, with a verified business address on Qixia Road. The supplier is classified as an imported tier with harbor trust status, indicating presence in export documentation systems. The listing does not state years in operation, workforce size, or client names. Response metrics show no recorded activity, suggesting limited buyer communication channels.

The company specializes in diesel fuel system components, particularly injector nozzles for commercial engine models. It does not claim ISO certification, OEM approval, or laboratory testing data. Production appears to be based on reverse-engineered or aftermarket specifications rather than licensed designs. Buyers should treat this supplier as a direct manufacturer without verified quality audits and request physical samples before bulk orders.
