论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。Though diesel engine Particulate Matter (PM) emission was widely investigated, the contribution of diesel fuel and lubricant were less studied because of the engine can not run without lubrication. Dimethyl Ether (DME) is an alternative fuel for diesel. Its molecular formula is CH3-O-CH3. When it is burned, there is no carbon or PAHs generated like conventional natural gas, gasoline, diesel, biodiesel,et al. To take the advantage of DME combustion, a CIengine was applied to run on diesel and DME, respectively, to study its PM emission characteristics. In the study, HORIBA MDLT-1302 system was used to sample the engine exhaust PM mass emission. The filter paper was weighted by a Sartorius ME5 electronic balance. PM number vs diameter distribution was detected by an Electrical Low Pressure Impactor (ELPI).The experimental results show that DME engine PM number is some 2 order lower than that of diesel engine. Lubricant contributes more under high engine load and speed conditions. Compared with DME operating conditions, lubricant contributes about 20% of PM mass.
