high reliability

High degree of engine reinforcement and 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, and the noise level at the rated power point of the engine is less than 97dB (A) per meter, which is 1-2dB (A) lower than that of competitors
The body adopts a gantry design, with high strength, low vibration, and significantly reduced noise
Using high-precision gears on the shearing gear ensures stable operation and further reduces mechanical noise; Multiple injection technology significantly reduces combustion noise

Ultra low fuel consumption

The minimum fuel consumption rate is 188g/kW • h, and the fuel consumption under common operating conditions is 3% -5% lower than that of competitors
The low-speed fuel consumption zone covers the common operating conditions of buses at 950-1450r/min, which is more fuel-efficient

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 light in weight, it is an ideal power source for buses over 12 meters in length
The engine can be equipped with three 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
