The report represents the beginnings of an effort to obtain appropriate means for measuring the odorous species in diesel exhaust and develop the quantitative relationships between these measurements and the exhaust odor. Through the integrated application of analytical chemistry and sensory methods, the major odorous species have been identified. Diesel exhaust odor can be described as having two major odor groups -- oily-kerosene and smoky burnt. The oily-kerosene odors are due principally to the alkyl-substituted indans, tetralins and alkyl benzenes in the aromatic portion of the unburned hydrocarbons. The smoky-burnt character is due primarily to the partial oxidation products of these same aromatic species, plus a smaller contribution from paraffin oxidation products -- specifically; alkyl, hydroxy, and/or methoxy-substituted indanones, phenols, benzaldehydes and alkenones.
