Product advantages

Emission requirements

  • Meet Europ VI emissions.

    • Economical

  • The minimum fuel consumption rate is as low as 188g/kW·h, which is the lowest in the same displacement.
  • The development of special data for buses is more suitable for bus application conditions, and it is 5.6% more fuel-efficient than competing products per 100 kilometers.

    • Dynamic

  • Through the precision standard of vehicle drivability data, the low-speed torque is optimized and improved, and the acceleration response is fast.
  • The low-speed and high-torque design.

    • reliability

  • The modular design of integral cylinder head, gantry body and accessories ensures reliability.
  • The life span of B10 can reach 1 million km.

    • Comfort

  • The low-vibration and low-noise gear train design comprehensively improves the NVH performance of the vehicle.

    • Adaptability

  • It can be adapted to the special structure of air conditioning, multi-parallel generator bus, and AT variable speed special power output structure to fully meet the diverse needs of buses.
