Chemical Species in Engine Exhaust and Their Contribution to Exhaust Odor

摘要

A study was made of the identification and characterization of compounds responsible for the odor of diesel engine exhaust. High-resolution gas chromatography was used to separate the organic components of diesel engine exhaust and evaluate their contribution to exhaust odor. Sampling procedures excluded water vapor collection and provided an enriched sample for analysis without the use of solvents. Exhaust components were classified into two general groups; those that are most probably odor irrelevant, and those that may contribute significantly to exhaust odor. (Author)
