At a glance
Supplied by an original Weichai diesel engine supplier, the Weichai WP10H is built as an Inline unit, with 9.5 L displacement. Rated output spans 276–294 kW (375–400 Ps). Peak torque reaches 1900 N·m. It is supplied to meet Euro VI emission requirements. Typical duty is rear-engine bus service.
Product Overview
The WP10H is a classic upgraded power model for buses. After several rounds of extreme-climate and complete-vehicle endurance evaluation it adapts strongly to operating conditions with high availability. Power reserve is substantial and output forceful, staying steady and composed under heavy loads on long-distance and mountain routes. Mature modular, integrated design with widely shared service parts and a simple maintenance routine makes later operation and upkeep effortless.
Product Advantages
