“…65% of the calorific value of diesel fuel [14]. Moreover, considering that the density of liquid DME comes to 80% of diesel fuel's density -to achieve a similar calorific effect, a twice greater quantity (in terms of volume) of DME must be injected to the engine's cylinder than that of diesel fuel [21].…”

This paper discusses briefly the production technology of dimethyl ether, taking into account plant raw materials and the physical and chemical properties of DME as compared to diesel fuel. The benefits and disadvantages of DME as a fuel are presented and changes in the emission of harmful substances characterised as compared to the combustion of diesel fuel. Also, basic usage problems are addressed, e.g. the wear of engine’s elements, cavity and leakages in the fuel system.

“…Furthermore, it puts the high efficiency of diesel combustion to its best use of achieving fuel economy. The use of a storage reduction-type NO x reduction catalyst has been proven to be highly effective in reducing NO x in DME engines [1]. However, the exhaust temperature of a compact engine is low; it does not perform well in terms of activating the catalyst.…”

“…Dimethyl ether (DME) features good compression ignitability and does not emit black smoke during combustion. When DME is used in heavy-duty diesel vehicles, the discharge of particulate matter (PM) and nitrogen oxides (NO x ) can be reduced to almost zero, while engine and vehicle performance levels remain equivalent to those of conventional vehicles [1]. However, a light-duty DME-fuelled truck has cost and space limitations with regard to adding a diesel particulate filter (DPF) and an NO x catalyst.…”

A light-duty truck diesel engine fuelled with dimethyl ether (DME) using a jerk-type in-line DME injection system, which meets the Japan 2009 Emission Regulation, was developed. It includes lower exhaust emission technology such as a large exhaust gas recirculation system with air-throttled and inter-cooled turbocharging. The National Traffic Safety Office, Environment Laboratory, and Bosch Corporation have demonstrated lowemission engines which reduce NO x emission levels to about 50 per cent of the 2009 emissions regulation without an NO x reduction catalyst system.

“…Dimethyl ether (DME) features good compression ignitability and does not emit black smoke during combustion. When DME is used in heavy-duty diesel vehicles, the discharge of particulate matter (PM) and nitric oxide (NOx) can be reduced to almost zero, while engine and vehicle performance levels remain equivalent to those of conventional vehicles [1]. However, a light-duty DMEfueled truck has cost and space limitations with regard to adding a diesel particulate filter DPF and a NOx catalyst.…”

A light-duty truck diesel engine fueled with DME using a jerk-type in-line DME injection system which meets the JAPAN 2009 emissions regulation was developed. It includes lower exhaust emission technology such as a large exhaust gas recirculation (EGR) system with airthrottled and inter-cooled turbo-charging. The National Traffic Safety office, Environment Laboratory and BOSCHCorporation have demonstrated low-emission engines which reduce NOx emission levels to about 50% of the 2009 emissions regulation without a NOx reduction catalyst system.
