Transfer of Thermal Energy to Selected Vibrational Bands in the Infrared
Abstract
Molecular gases are considered as possible additives to the exhaust stream of internal combustion engines with the purpose of transferring thermal energy of the exhaust gases to vibrational energy of the additives in order to reduce the temperature of the exhaust gases and the manifold system. The gases considered are carbon dioxide bromotrifluoromethane, vapor from ethylene glycol coolant solutions, and in some cases air and nitrogen. These gases are introduced into the exhaust stream of a hydrocarbon burner specially constructed for use in the laboratory. Emission spectra in the infrared region from 2 to 16 micrometers are presented for the heated exhaust gases and parts of the exhaust port. CBrF3 is the only additive, of those presented, which produces a sufficient effect within the criteria established to warrent further study.
