High reliability
- The products jointly developed by Weichai European R&D Center and AVL AUStria have a high degree of engine enhancement
- The B10 life exceeds 1.2 million kilometers
Excellent NVH performance
- Multi-wedge automatic tensioning structure at the front end, fully map noise optimization, good comfort
- DOE injection calibration for improved smoothness
- Optimize the stiffness of the shaft train and the large size shock absorber to improve sound quality
- Multiple injection technology to reduce combustion noise significantly
Ultra-low fuel consumption
- Minimum fuel consumption rate 185g/(kW•h)
- The low-speed fuel consumption area covers the typical conditions of Buses ranging from 1000-1500r/min, which also saves fuel
Powerful
- Maximum torque 2110N•mallows a smaller rear axle ratio to be selected while maintaining power, further reducing fuel consumption
Adaptable
- Power loss at 2800 meters above sea level, ultra-low power loss at 4500 meters of typical operating conditions
- Starting zero at -20°C in low temperature environment failed
Adaptability
- The engine can carry 2 and 3 generators in parallel, to meet the power needs of all types of Buses
- The body's air conditioning carries the structure, and the air conditioning does not come into direct contact with the entire carriage, further improving the NVH performance of the whole vehicle and improving the quality of the whole vehicle
