Import Different Type Of Nozzles Diesel Yanmar Nozzle — Buy in Bulk from Supplier in China

These diesel nozzles are designed for Yanmar engines and are manufactured to match original equipment specifications for fuel delivery and atomization. The nozzles feature a single-hole or multi-hole configuration depending on engine model, with nozzle orifice diameters ranging from 0.18mm to 0.25mm, and needle lift values between 0.1mm and 0.2mm, consistent with Yanmar’s industrial diesel standards. They are machined from high-carbon chrome steel with a hardened surface finish to resist erosion from high-pressure fuel flow.

The material composition typically includes 1.4021 or equivalent stainless steel grade, offering corrosion resistance against sulfur-containing diesel fuels. Surface hardness exceeds 58 HRC after heat treatment, and internal flow channels are honed to a Ra 0.2 finish to ensure consistent spray patterns. These are not generic replacements but engineered for Yanmar’s combustion chamber geometry, with spray angles of 15° to 22° and atomization quality validated against ISO 4113 standards.

They are used primarily in agricultural tractors, marine generators, and construction equipment powered by Yanmar 3T series and 4T series engines. Buyers include OEM aftermarkets, diesel repair shops, and fleet operators in Southeast Asia and Africa. Packaging is in sealed anti-rust paper with inner foam inserts, typically 10 to 50 pieces per carton. Trade terms include FOB Shanghai and T/T payment, with MOQs starting at 100 pieces per nozzle type.

Zhengzhou Liseron Machinery Co., Ltd. is based in Zhengzhou, Henan Province, China, and operates as an importer and distributor of diesel engine components. The company is listed as a harbor-tier supplier with verified factory access but provides no public details on production capacity, workforce size, or years in operation. Their listing confirms they source and supply diesel nozzles for Yanmar engines, with no indication of in-house manufacturing capability.

The supplier has no publicly disclosed certifications, revenue figures, or client list. Response metrics are unavailable, and there is no evidence of direct factory ownership or ISO compliance claims. Buyers should treat this as a trading entity sourcing from third-party manufacturers, and should request batch test reports for each shipment to validate performance against Yanmar OEM standards.
