CRC EVALUATION OF TECHNIQUES FOR MEASURING HYDROCARBONS IN DIESEL EXHAUST - PHASE IV
A multi-cylinder diesel generating set was circulated among 15 participating laboratories, and each laboratory measured exhaust hydrocarbon by methods that complied with SAE Recommended Practice J215, "Continuous Hydrocarbon Analysis of Diesel Exhaust." They also measured hydrocarbon concentrations of two bottled gases having unknown compositions. Analyses were fairly consistent within laboratories both on bottled gases and engine exhaust the standard deviations were 3% and 10% of the grand average repectively. However, analyses differed substantially among laboratories both on bottled gases and engine exhaust; the standard deviations were about 10% and 22% of the grand averages, respectively. These results scatter more than desirable for engineering measurements, and they indicate that further improvement should be sought in techniques for analyzing hydrocarbons in diesel exhaust.
