Product advantages

High reliability

  • The cylinder block and cylinder head made of vermicular graphite cast iron guarantee a high strength.
  • The design life is 32,000h.

High economy

  • The high efficient combustion technology, high efficient high turbocharging technology, high-pressure common rail fuel injection technology and intelligent control technology are adopted, and the optimal structure is selected via combustion simulation to achieve low fuel consumption and high reliability.

High maintenance convenience

  • Observation windows are arranged on both sides of the engine block for easy replacement of connecting rod and connecting rod bearing bush.

Good environmental adaptability

  • The standard intake heater with reserved water inlet and outlet interfaces guarantees good low temperature starting performance.
  • The engine has good plateau adaptability and can operate reliably when the altitude is 4,000m.
