...Utkarsha Sonawane; Avinash Kumar Agarwal Dimethyl ether is a new-generation alternative fuel to mitigate cold-start issues in compression ignition engines. It has a higher cetane number and offers superior spray atomization and fuel evaporation characteristics. This simulation study compares...

...Balram Sahu; Dhananjay Kumar Srivastava Dimethyl ether appears to be a better choice among various diesel alternatives due to its high cetane number and sootless combustion. However, the physical and chemical properties of dimethyl ether are very different from those of diesel. The physical...

... emissions and low thermal efficiency, particularly at low loads. The objective of this study is to achieve dual-fuel engine thermal efficiency and emissions better than those of a diesel mode while utilizing alternative fuels. A new approach consisting of a combined strategy using dimethyl ether (DME...

...Magd N. DinAli; Ibrahim Dincer A new renewable energy based dimethyl-ether (DME) production system is proposed in this paper. The DME is then produced through the indirect synthesis method where methanol is produced first through carbon hydrogenation process, then methanol derived to a process...

... on a four stroke, direct injection dimethyl ether (DME) engine were conducted. Experimental results show that as the fuel temperature increases from 20 to 40 °C, the sound speed is decreased by 12.2%, the peak line pressure at pump and nozzle sides are decreased by 7.2% and 5.6%, respectively. Meanwhile...

...Tao Han; Hui Hong; Hongguang Jin; Chuanqiang Zhang Dimethyl ether (DME) is a promising alternative fuel, but direct combustion of DME will result in extra energy penalty for CO 2 separation. In this paper, an advanced power-generation system with CO 2 recovery integrating DME fueled chemical...
