Advantages of CCEC NTA855-P450 Pump Engine

  • Lower oil consumption, Extended stroke, the expansion of the combustion gas more fully, Increase effective efficiency output, the economy is better.

  • Strong power, advanced 4 air valves structure, greater horsepower, air burning more thoroughly, while making low speed torque increase, quicken response speedily, climb strongly.

  • Excellent reliability, with compulsive cold cut articulated pistons, Can bear extreme high mechanical load and heat load, Strength can be comparable with heavy engine.

  • Better emissions, Decorate injector and symmetrical combustion chamber in center, make the cylinder is more homogeneous mixture, burning more fully, lower emissions.

  • Super life, 30 % engines 800,000 km without overhaul.

  • Excellence power, Clean burning, use the advanced lean-burn closed loop electronic control system.

  • Excellent cold start performance, equipped with air suction electric preheater and 7.8 kW power starter, completely improve the cold start performance of the engine. Through the arctic village-MoHe of China -36 °C extreme low temperature validation.
