Dimethyl Ether (DME) was mixed with waste vegetable oil to improve combustion and exhaust emissions in a high speed diesel engine. Past research has shown that the properties of DME, such as lower boiling point and higher cetane number, would affect atomization process and combustion progress of DME/Marine diesel oil blending fuel. In this study, the effect of mixing DME with waste vegetable oil was investigated by using the 4-stroke single cylinder direct injection diesel engine. The combustion pressure history, injection pressure, exhaust gas emissions were measured in variation with mixing ratio of DME and engine load. The emissions of smoke and nitrogen oxide were found to reduce with increase in mixing ratio of DME.
