Product advantages

  • Emission standards: Euro V and Euro VI.
  • Power performance: High power, high torque (and high output torque at low speed).
  • Economy: The optimized powertrain system ensures low fuel consumption; the engine is able to achieve high mechanical efficiency at low speed, ensuring low fuel consumption.
  • Comfort: The customized development of NVH ensures low noise and vibration
  • More safe and reliable

  • B10 life is greater than 1,000,000 km.
  • Better economy

  • The speed that can achieve minimum fuel consumption covers the whole working speed range.
  • The intake and exhaust manifolds are arranged on different sides, improving charge efficiency, optimizing combustion, and improving economy.
  • High configuration

  • The integrated rotor-type oil pump and standard shear gear reduce transmission noise further.
