Formatted abstract
 The University of Queensland.s Department of Mechanical Engineering has begun research on the use of Dimethyl Ether for its use in diesel engines. Dimethyl Ether has a high potential as an alternative to conventional diesel oils. Due to its suitable cetane rating and the reduction in engine pollutants such as oxides of nitrogen and particulates.

The current engine that will be used to test DME fuels is a 1.6L PSA diesel engine. Thediesel fuel system will be replaced with a design that is tailored to the properties of a liquified gas fuel to increase reliability and repeatability for accurate testing data. The fuel system described in this report incorporates a purge system to aid in the removal of vapour build up prior to starting the engine. The same purge system also allows for the safe evacuation of liquified DME to the atmosphere to prepare the fuel system for prolonged shutdown period or maintenance. The liquid DME fuel will exit the system in vapour form, through the use of a flash tank designed to ensure no fluid is released into the ventilation system for safety concerns.

Basic operational procedures are provided to perform startup, shutdown and system purging. These procedures are provided for future members of the UQ DME team to build upon to construct a complete set of operating procedures for the testing facility. Such comprehensive procedures were not able to be produced due to unforseen complication and delays of the test facility zoning; as such safety guideline had yet to be produced for the time of this document (2011).
