Characterization of Particulate Emission from Swirl Chamber Type Light-Duty Diesel Engine as a Function of Engine Parameters

The diesel engine particulate that was measured by the U.S. certification test method was known to comprise the dry soot and the soluble organic fraction. The objective of this paper was to clarify how a variety of engine parameters effected the emission each of dry soot and soluble organic fraction and, in turn, the total particulate emission level, thus to make a contribution to studies on particulate reduction. In this paper were shown measurements of dry soot and soluble organic fraction in the particulate emitted from a Mazda 2.2 liter swirl chamber type diesel engine operated at steady state condition with various engine parameters. In addition, the gaseous emissions of HC, NOx and formaldehyde measurements were taken simultaneously.
