VEHICLE EMISSION CHARACTERISTICS USING MECHANICALLY EMULSIFIED ALCOHOL/DIESEL FUELS

Alcohol/diesel fuel mixtures have been used to fuel diesel engines typically operated at steady-state mode. These systems have been limited to introducing alcohol by fumigation or by premixed fuel. An optional method of alcohol utilization involves emulsifying the alcohol/diesel fuel mixture prior to introduction into the engine fueling system. A light-duty diesel vehicle fueled with an emulsified alcohol/diesel fuel was operated under cyclic mode. Emission and fuel economy measurements were taken during vehicle operation. The test results showed the volumetric fuel economy decreased slightly. Carbon monoxide emissions increased slightly, and oxides of nitrogen showed no significant change. Particulate emissions were reduced slightly, and the particulate extractables increased slightly. The environmental effect of these data cancel each other resulting in no significant changes in the total release of biological activity into the environment.
