Development 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 کاملModelling and simulation of a direct synthesis of dimethyl ether (DME) in a tubular reactor with a hybrid catalyst bed
This work includes a modelling and simulation of dimethyl ether direct synthesis in a tubular type reactor with hybrid catalysts bed. The results of simulation show that the loading ratio of methanol synthesis and dehydration catalysts has a important influence on product yield.
متن کاملDimethyl Ether Production from Gasification of Victorian Brown Coal - Process Model and Related Preliminary Experiments
Being reactive and spontaneously combustible, dried Victorian brown coals can not be exported, and have to be used in mine-mouth power stations which also suffer from low efficiency and high CO2 emission. Synthesis of dimethyl ether (DME) is an option for the production of liquid fuel, a transportable product for power generation and transportation. This paper presents a steady-state process mo...
متن کاملEffects of High EGR Rate on Dimethyl Ether (DME) Combustion and Pollutant Emission Characteristics in a Direct Injection Diesel Engine
This study investigated the effects of high exhaust gas recirculation (EGR) rates on dimethyl ether (DME) fuel combustion performance, exhaust emissions and particle emission characteristics in a small direct injection diesel engine under various injection timings. To examine the effect of EGR and injection timings, the experiment was performed under high EGR rates (0%, 30%, 50%) and injection ...
