Abstract
The body of information presented in this paper Is directed towards engineers in the field of environmental sciences involved in measuring and evaluating the emissions from a variety of diesel engines or vehicles. This paper summarizes recent data obtained by EPA on identification and quantification of different emissions (i.e. characterization) from a variety of diesei engines. The effects of turbocharging, advanced injection timing, indirect vs. direct injection, exhaust gas recirculation (EGR), and different fuel pumps on HC, CO, NO x , sulfates, aldehyde, and particulate emissions were determined by testing several heavy duty diesel engines. A heavy duty gasoline engine was tested for comparison. Limited testing was done on a diesel bus engine under malfunction conditions (conditions different from manufacturer’s recommended specifications).This publication has 0 references indexed in Scilit:
