Carbon monoxide and dioxide, methane, ethylene and acetylene in auto-exhaust gases were determined by their infra-red absorption spectra. Characteristic bands for the determination were: carbon monoxide 2360 cm-1, carbon dioxide 660 cm-1, methane 1300 cm-1, ethylene 950 cm-1 and acetylene 730 cm-1. Minimum detectable limits were: carbon monoxide 0.1%, carbon dioxide 0.3%, methane, ethylene and acetylene 0.02%. Concentration of five components in the exhaust gases of ten vehicles were: carbon monoxide 1.09.7%, carbon dioxide 2.610.0%, methane trace0.42, ethylene trace0.13% and acetylene trace0.42%.
