Hubei Engine Plant
To build a smart factory and establish a benchmark for the Power Business Unit (BU) and the industry, the Hubei Power Project Team was established in February 2025.
Located in Daye City, Hubei Province, it covers a total area of 160 mu, mainly including a machining workshop and an assembly & test workshop, with 5 production lines, mainly producing EN gasoline engines.
Machining Workshop
Composed of three core modules: production lines, centralized cooling system and intelligent warehousing, it is a digital, intelligent and green modern production base.
Cylinder Block Line
The cylinder block line adopts imported German GROB 5th-generation machining centers, coupled with industry-leading robotic cleaning machines. It applies a combined process of fine boring + honing + process cylinder head.
The surface roughness of cylinder bores is controlled at Ra 0.2–0.4 μm, improving wear resistance and sealing performance.
Cylinder Head Line
The cylinder head line adopts imported German GROB 5th‑generation machining centers.
The cylinder head combustion chamber is processed with milling cutter technology, which delivers higher surface quality than traditional casting technology, optimizes air flow characteristics, and improves combustion efficiency.
Crankshaft Line
The crankshaft line uses imported equipment including German HELLER and Hegenstatt machines, plus US micron-grade precision measuring devices.
With turn-broaching, precision grinding, fillet rolling and journal induction hardening, surface hardness rises by about 50%, and fatigue strength increases by over 30%.
Assembly & Test Workshop
This hermetically sealed, thermostatically controlled clean workshop integrates precision processes: tightening, press-fitting, leak testing, dispensing, and lubrication, with a line automation rate of 35%.
