SC9DF diesel engine is a new-generation heavy duty engine developed aiming at compliance with Euro IV and future emission standards on the basis of D 114 engine successfully applied at home. in the development of the engine , the development trend of diesel engines in China and the world has been taken into consideration and technical resources of both domestic OEMs/parts suppliers and American , German , Japanese , British, Canadian top engine research organizations have been integrated . DC9DF engine has reached an advanced contemporary world level in terms of power performance, fuel consumption, vibration /noise and service reliability.
Powerful Output: 9L , golden displacement heavy-duty truck engine , with maximum power output up to 380 PS;
High Economy: Low specific fuel consumption within the operating zone , minimum 190 g/kW.h;
High Reliability: Combining with heavy-duty engine design experiences of many countries , B10 service life of the engine over 800,000 km;
Low Emission: With electronically controlled high-pressure common rail technology, compliant with Euro IVemission regulation, the Euro Ⅲ product first introduced into market in 2006;
Low Noise : Lower than 93 dB(A),meeting China Stage Ⅱ noise standard quite easily;
High Braking Power: Equipped with most widely used American Jacobs in-cylinder exhaust braking system, providing vehicles with super-strong braking force from the engine, thus greatly improving transport efficiency, lowering truck use cost.
