Diesel odor measurement: comparison of two methods
Technical Report
·
OSTI ID:6943273
The Department of Energy's Bartlesville (Okla.) Energy Technology Center (BETC) continues to investigate the influence of exhaust-treatment devices on emissions from diesel engines used in underground mining applications, studying the effects of such devices on exhaust odor levels. Two methods of odor evaluation are used routinely--a human odor panel and the Arthur D. Little Diesel Odor Analysis System. Results obtained in a study involving two engines and four catalytic reactors show that the oxidation catalysts decreased exhaust-odor intensity as measured by both methods. However, there was poor statistical correlation between intensity values measured by the two techniques. Although directionally similar results were obtained by the two techniques, absolute values of odor intensity for one method cannot be reasonably well estimated from measurements via the other method.
