Attempts to reduce diesel exhaust odors, particularly from city buses, are reviewed along with some of the problems associated with odor measurement. Most research on diesel exhaust odor utilizes the Environmental Protection Agency Diesel Odor Quality-Intensity Rating System which consists of 28 plastic squeeze bottles, each partially filled with a different intensity or odor. A trained panel routinely evaluates simultaneously presented dilute exhaust in terms of the squeeze bottle standards. The major problem in odor research is the lack of a relatively simple but precise odor indicator other than the nose. Among the many odor control methods attempted, the use of DF-1 diesel fuel and improved fuel injectors along with increased upshift speeds appear to offer promise for reducing exhaust odors. Less complicated measurement procedures are required, however, before substantial commitments can be made by manufacturers in designing engines with essentially negligible exhaust odor.
