Product advantages

Special structure

  • The intake/exhaust structure is optimized, reducing flow resistance and the height of the engine.
  • The special flat-bottomed oil sump is used, which reduces the height of the engine, as well as vibration and noise.
  • The rear-mounted air filter is used, which reduces the width of the engine and ensures easy maintenance.

Economy

  • Fuel consumption for the load rate between 60% and 90% is optimized specially, such that low fuel consumption is guaranteed.

Environmental adaptability

  • Low temperature adaptability: The engine can start directly at -10℃ without auxiliary measures and smoothly at -30℃ by means of intake preheating.
