Characterization of Heavy - Duty Diesel Gaseous and Particulate Emissions, and Effects of Fuel Composition

Abstract

Gaseous and particulate emissions from two heavy-duty diesel engines were characterized while the engines were operated on five different fuels. Characterization included mass rates of major exhaust products, plus analysis of particulate matter for sulfate, trace elements, major elements, total solubles, and other properties. Analysis of rate and composition data was conducted with regard to fuel and engine effects on particulate. Two large particulate samples were also collected for alter analysis on groups of organics present.
