Determination of Carbon Oxide in Exhausts of Vehicles by Thermocatalytic Method

Abstract

Selective methods of thermocatalytic determination of carbon oxide and hydrocarbons in exhaust gases of vehicles are based on measurement of different thermo effects of oxidation of a combustible mixture, obtained from two identical thermosensible elements working at different temperatures are developed. At one temperature there is an oxidation of all analyzed gas mixture, and on another-the mixture without a selectively determined component and by the difference of thermo effects an exact concentration of components was determined.
