Business Segment
One group, three core business drivers
Rooted in precision manufacturing, we have built a comprehensive power‑generation industrial chain that spans from core components of reciprocating engines and thermal‑management and cooling systems to gas turbines and power‑plant equipment, covering the full spectrum from “components → systems → power plants.”
Core engine components
Engine Core Components
Research, development, and manufacturing of cylinder blocks, cylinder heads, connecting rods, and robotic components for diesel, gasoline, and natural gas engines. The company serves the commercial vehicle, new‑energy vehicle, marine, power‑generation, and eVTOL sectors, holding approximately one quarter of the domestic market share for diesel engine cylinder blocks and cylinder heads.

Key Process in Cylinder‑Block‑Free‑Linering Technology for Automotive Engines: Coated Honing
The cylinder‑liner‑less technology for automotive engines originated in Europe. It employs thermal spray coating to apply a wear‑resistant layer to the inner walls of aluminum engine cylinders, replacing conventional cast‑iron liners. This approach not only reduces engine weight and fuel consumption but also significantly lowers friction, thereby enhancing engine performance.
