high reliability

The product jointly developed by Weichai Europe R&D Center and AVL Austria has a high degree of engine reinforcement and a large design margin
B10 has a lifespan of over 1.2 million kilometers

Excellent NVH performance

The front end adopts a multi wedge belt automatic tensioning structure, with full MAP noise optimization and good comfort
DOE spray calibration improves smoothness
Optimize shaft stiffness and large-sized shock absorbers to improve sound quality
Multiple injection technology significantly reduces combustion noise

Ultra low fuel consumption

The minimum fuel consumption rate is 185g/kW • h, and the fuel consumption under common operating conditions is 3% -5% lower than that of competitors
Low speed fuel consumption zone covers common operating conditions of buses at 1000-1500r/min, which is more fuel-efficient

Powerful

The maximum torque is 2110N. m, and a smaller rear axle speed ratio can be selected while ensuring power, further reducing fuel consumption

Adaptable

At an altitude of 2800 meters, there is no power reduction, and at 4500 meters, there is ultra-low power loss under common operating conditions
Zero startup failure at -20 ℃ in low-temperature environment

Powerful

On the premise of ensuring power, a smaller rear axle speed ratio can be chosen to further reduce fuel consumption

Adaptable

At an altitude of 2800 meters, there is no power reduction, and at 4500 meters, there is ultra-low power loss under common operating conditions
Zero startup failure at -20 ℃ in low-temperature environment

Good adaptability

Small in size and lightweight, it is the ideal power source for 18 meter BRT buses
The engine can be equipped with 2 or 3 generators in parallel to meet the electricity needs of various types of buses
The main air conditioning system is equipped with a structure that does not directly contact the vehicle frame, further enhancing the vehicle's NVH performance and improving overall quality
