China high quality engine parts injector/piston ring/connecting rod

Fuel Injector Series

Utilizing nano-level precision machining and adaptive fuel injection technology, we achieve supercritical atomization at injection pressure. Our unique "honeycomb" multi-hole design minimizes fuel particle diameter, and combined with an intelligent control module, reduces soot emissions by 23% and improves fuel efficiency by 8.7% compared to conventional products.

Piston Ring Assembly

Utilizing a "three-body composite" plasma-sprayed tungsten carbide coating, the "three-body composite" technology delivers exceptional surface hardness. The innovative asymmetric cross-section design ensures more uniform contact pressure distribution on the lands. Combined with our proprietary impregnation process, it maintains excellent lubricity even under cold-start conditions. Test data demonstrates low wear and reduced oil consumption, making it ideal for the long-life requirements of turbocharged direct injection engines.

Connecting Rod Assembly

This forged steel connecting rod, designed based on topological optimization, utilizes a "thermal expansion and contraction" assembly process. By incorporating aviation-grade fracture mechanics analysis models, we innovatively employ an involute tooth profile in the connecting rod big end, achieving bearing clearance control accuracy of ±0.005mm.
