Abstract:
To further explore the application of dimethyl ether as an alternative fuel for diesel engines, the tests were carried out to determine the engine performance, combustion characteristics, and emission properties of a diesel engine fueled with dimethyl ether diesel blended fuel. A novel lowpressure fuel supply system was developed, which can eliminate the vapor block problem in the fuel system under all operating conditions of the engine. The results indicate that there is a significant improvement in engine performance compared to the one of diesel engines, such as a lower fuel specific consumption rate, a decrease of soot emissions around 30%, and a mean reduction of NOx emissions about 36%. 9 figs, 9 refs.
