    Product Features

  • Strong power: Such components as turbocharger, high-pressure fuel pump and fuel injector are optimally configured to obtain wide power range, sufficient power reserve, and large torque. Hence, the engine has large torque even at low speed, and is better adaptive to various operating conditions.
  • Fuel economy: It uses four-valve technology, and is provided with a pulse conversion turbocharger to make possible the more sufficient combustion, low fuel consumption, and wider operating range at low fuel consumption, and through the optimization of various engine oil seals, reduce the engine oil consumption by 45%.
  • Safe and reliable: The high-strength QT800 one-piece crankshaft, large flow lubrication system with a filtering and cooling function, and high-efficiency cooling system, and less-pipe and one-cylinder and one-head design ensure reliable operation and convenient maintenance of the diesel.
