In recent years, energy demand has been growing significantly. In acknowledging this growth, limited energy supply and environmental problems, many alternative fuels have been researched on, enabling our economic and environmental status in be maintained in the future.
Dimethyl Ether (DME) is a new fuel that has a remarkable potential to be one of the new generation of energy resources for power generation, industrial application and diesel transport system. DME is proven to be efficient due to its cetan number while being environmental friendly with its sulphur free characteristic. The exhaust emission during combustion has been proven to have extremely low particle and carbon content. It also produces lower noise during operation and lower fuel consumption as compared to other fuels
The aim of the project is to assess the effects of using DME on diesel engine on performance, combustion and emission. The primary objective of this thesis is to develop and design a comprehensive standard operating procedure for the experiment backed by the various stringent standards. ISO 15550 will be referred to closely as it outlines the requirements for the measurement of engine power. Along with ISO 15550, ISO 3046 outlines the declaration of power and test methods. The other main parameter that will be collected is exhaust emission, ISO 8178 outlines the standards for exhaust emission measurement.
The development and use of the procedures will be an integral part of the experiment as it provides individuals with the information to perform the experiment properly, and facilitates consistency in the quality and integrity of the results.
In this report, research showed the appropriate application of DME as an alternative fuel in diesel engines. From this research, more experience and tests are required to be conducted to develop a standard for performance testing and exhaust emissions testing.
