Study on the performance of DME Fuelled DI diesel engine

摘要

The paper presents the research results of DME powered engine and vehicle. The combustion and emissions characteristics are compared with those of diesel engine. A DME powered van is developed and its trial operation is carried out on highway. The preliminary operating results show that the combustion noise is equivalent to that of gasoline powered vehicle under frequently operating speed and smoke free combustion is realized. The maximum speed and accelerating performance are equivalent to those of diesel powered vehicle. Studied results show that DME is an excellent and environment friendly alternative fuel for diesel engines.
