Abstract
A ten-person odor panel, trained in the characterization of dilute diesel exhaust samples according to the PHS quality/intensity rating kit and the PHS light-extinction smokemeter, were used to measure odor and smoke. A commercially available diesel fuel odor additive had no effect on perceived odor from three two-cycle Detroit diesel 6V-71 E powered municipal buses, and inconsistent reductions in odor generally resulted from a catalytic muffler device. Both odor and smoke were less from similar buses powered by a 6V-71 N type engine. A number of truck-tractors with a variety of engines and drivelines were evaluated to develop dynamometer procedures and acquire limited baseline emissions. Due to low exhaust temperature and unsteady flow conditions with extended engine idle, the city bus exhaust represents one of the most difficult to treat by catalysis, and a number of catalytic devices employing both transition metal and precious metal catalyst coatings were unsatisfactory. An electrostatic precipitator was completely unsuccessful in reducing smoke. Fuel seemed to have little or no effect on perceived odor from three buses powered by 8V-71 N engines. (Author)
