ABSTRACT

The present paper investigates into the effect of dimethyl ether (DME) temperature on a turbocharged DME engine that is used as a research object. The research results show that the DME temperature rises gradually in fuel tank during the engine running, and the system temperature is balanced after a period of time. When the DME temperature rises from 28°#176;C to 40°C, the engine power decreases by 8.0% from 132.2 kW to 121.6 kW in 1400 r/min; it decreases by 12.0% from 192.1 kW to 168 kW in 2200 r/min. At the rated working conditions, the DME engine power decreases by averagely 1.0% when the DME’s temperature rises by 1°C.
