Abstract

West Virginia University (WVU) currently has a Transportable Emissions Laboratory capable of measuring the exhaust constituents produced by a heavy duty diesel engine. The laboratory has the capability of measuring the exhaust constituents from a partial exhaust stream of a locomotive diesel engine. As the field of locomotive engine emissions testing broadens, it has become desirable for WVU to develop a laboratory that is capable of sampling the gaseous exhaust constituents produced by a locomotive engine from a raw, undiluted gas stream, in tandem with a partial flow dilution tunnel system for particulate matter. This document provides the design philosophy behind such a laboratory, as well as laboratory studies to verify the proper functionality of such system. Results from the study include the comparison of gaseous emissions between WVU's Engines and Emissions Laboratory (EERL) full exhaust dilution tunnel system resulting in laboratory percentage differences of 3.4%, 3.57%, 0.33%, and 2.93% for hydrocarbons, oxides of nitrogen, carbon dioxide, and carbon monoxide, respectively. The partial flow dilution tunnel system was tested on a locomotive engine. The results from that study produced an overall system percentage difference of 4.8% for the line-haul mode of the first engine, 5.69% and 8.2% for the line-haul and switch mode, respectively for the second engine.
