Product advantages

  • Emission requirements: comply with Euro Ⅵ emission standards.
  • Strong power: maximum torque of 3000 N·m, with a maximum torque range starting from 900rpm.
  • Economy: achieves the lowest fuel consumption rate of 171 g/kW·h.
  • Comfort: custom development for vehicle NVH, ensuring low noise and vibration levels.
  • Generality: designed with modularity in mind, maximizing parts compatibility and maintainability. Lightweight: GZ weight reduced to 1010kg through the use of numerous cast aluminum and high-strength plastic components, resulting in lighter products with equivalent power.
  • Highly reliable

  • Adopt high reliability system solution to cover the adaptability verification of all working conditions, and create a reliability benchmark in the industry.
  • The body, piston, bearing and other comprehensive improvements, B10 life of 1.8 million kilometers.
  • Economy

  • Positioning of the main line standard load tractor, for "all conditions" adaptive development.
  • The world's first commercial diesel engine platform product that breaks through 52.28% thermal efficiency.
  • Adopt high efficiency and low heat transfer combustion technology, air system coordination matching, high compression ratio and high explosive pressure combustor, high precision injector, high charge airway design and other high thermal efficiency engine technology.
  • Minimum fuel consumption 171 g/kW·h.
  • Powerful

  • Maximum torque 3200 N·m, maximum torque range down to 900rpm, low-speed power superior, through intelligent electronically controlled supercharging, precise supercharger speed control and other means, on the basis of large horsepower and large displacement, but also has a minimal plateau loss and faster response speed, whether steady or transient, power on call.
  • Lightweight Design

  • Modular design, integrated fuel filter, integrated machine cooling module.
  • Application of new materials, cast aluminum flywheel shell, high strength plastic oil pan, etc.
  • Excellent NVH performance

  • Sound insulation and shock absorption technology such as body strengthening design, cylinder head cover and plastic oil pan suspension design, further reduce vibration and noise, 2-3 dB(A) lower than the same level products.
