Notice of RetractionStudy on the application of D30 blended fuel

The paper introduces application of D6114ZLQB turbocharged and cold diesel engine fueled with Dimethyl Ether and diesel, including the power performance, economical efficiency, and exhaust emission characteristics. Based on the analysis on the properties of D30 (the ratio of DME and diesel is 3 to 7 )blended fuel, a series of job have been done such as designing the fuel supply system of diesel engine and optimizing the parameters of fuel pump and injector, both of which were processed on bench test of the engine. The testing result shows: the power of engine when applying D30 blended fuel is not less than that of original diesel engine (diesel without blended fuel); the fuel economy is enhanced at high speed and load; NOX emission declines obviously at low speed and load while there is no difference with that of the original engine at high speed and load; HC decreases slightly and CO has no apparent change; PM declines largely during all the whole revolution. The result presents that turbocharged and cold diesel engine fueled with DME and diesel has better performance in declining exhaust emission.
