Research and Assessment of Applying Dimethyl Ether “DME” Extracted from Natural Gas “Ng”, on Diesel Engine as a Clean Fuel (TECHNICAL NOTE)
Due to the shortage of liquid hydrocarbon fuels for compression ignition engines, researchers have constantly been looking for alternative fuels. Recently, dim ethyl ether (DME) with its interesting properties, such as high cetane number and low exhaust emission has drawn a lot of interst as a suitable fuel for diesel engines. The main objective of this study was to assess the potentials and fe...
متن کاملDevelopment of a Dme (dimethyl Ether) Fueled Heavy-duty Engine with Lean Nox Trap
In recent years, attention has focused on smokeless, sulfur-free dimethyl ethyl (DME) as a clean fuel for heavy-duty diesel vehicles. As a part of its Next-Generation Environmentally Friendly Vehicles Project (EFV21), the Ministry of Land, Infrastructure and Transport has developed a heavy-duty truck in the 20-ton class that uses DME as its fuel. A lean NOx trap system (NSR Type: NOx Storage Re...
متن کاملVapor-Liquid Equilibrium of a Ternary System containing Dimethyl ether (DME) and Light Hydrocarbons
Recently, dimethyl ether (DME) has been paid much attention as a clean fuel. DME has many advantages as a substitute for liquefied petroleum gas (LPG). Sulfur oxides (SOx), and particulate matters (PM) are not produced at the combustion. Infrastructures and equipments for LPG can be used with slight improvements, because physical properties of DME are similar to those of light hydrocarbons, pro...
متن کاملDirect Dimethyl Ether Fuel Cell with Much Improved Performance
Due to several apparent advantages over methanol, dimethyl ether (DME) has been viewed as a promising alternative fuel for direct fuel cell technology. Similar to methanol, DME oxidation requires a surface oxidant, such as OH, for the removal of adsorbed CO. Consequently, the reaction occurs at much faster rates on binary PtRu catalysts than Pt alone. In this work, PtRu catalysts with a wide va...
متن کاملAnode Catalysts for the Direct Dimethyl Ether Fuel Cell
For the last decade, dimethyl ether (DME) has been considered a promising alternative fuel for direct fuel cells because of several advantages over methanol. In this work, PtRu catalysts with a wide range of Pt-to-Ru ratios were screened for the direct DME fuel cell (DDMEFC) performance for the first time. Overall, Pt50Ru50 performs best in the high and middle voltage ranges, whereas Pt80Ru20 p...
