Abstract
DME is widely gaining acceptance as an alternative fuel for diesel engines. DME is a clean fuel that does not emit soot, PM, and SOx. It has a high cetane number, and is suitable for diesel engines. According to its exhaust characteristics, NOx reduction is easily attained by engine tuning and by applying a large amount of EGR. Focusing on these advantages, JFE Engineering and Daihatsu Diesel have jointly developed a DME diesel power generation system and constructed a 1250kW DME demonstration plant. Technical tests for various elements and continuous endurance tests were completed, and its potential for practical use was confirmed. This paper describes the outline of the world's first large-scale power generation DME plant, presents distinctive test results, and also describes the future of DME fuel.
