Advantages of DCEC L9NS6B340 Automotive 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.
