Abstract
In this study, DME is used to fuel a retrofit-type diesel engine, and operational tests were carried out using a distributor-type injection pump. In this experiment, comparison and examination of the effects of the engine performance. And when using DME as a new fuel, the fuel temperature affects the engine performance. Therefore, fuel temperature operations carried out using the in-tank pump and feed pump, and the DME circulation quantity increased. Moreover, exhaust gas effect of decreasing by the EGR was examined. As a result the fuel circulation quantity increase enabled the DME temperature control by in-tank pump and feed pump. In addition, the engine performance was able to stabilize. And NOx emission of 3.79 g/kWh obtained. Therefore, it was possible to clear the exhaust gas current emission regulation, and it is regarded as also clearing the exhaust gas new short-term emission regulation.
