Ecological Systems and Devices Annotation << Back Maintenance of selectivity thermacathalytical sensor control of components of ex-haust gases Abdurahmanov E., Daminov G., Sultanov M., Tillaev S. The way of maintenance of selectivity thermocathalytical definition of separate components of exhaust gases of a vehicle is developed. Thus the maintenance of selectivity thermocathalytical definition is reached(achieved) by measurement of a difference thermo effects of oxidation of a combustible mix received from two identical sensitive elements working at different temperatures. At one of these temperatures gets oxidation all mix of combustible substances. And at another – mix without a selectively determined component. On a difference thermo effects judge concentration of a determined component. E-mail: ergash50@yandex.ru
