Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To enable the reduction of effect of moisture content by correcting the concentration detecting signals of a gas sensor according to a moisture content in exhaust gases estimated from the operating conditions of an engine. SOLUTION: Electromotive force which occurs in an oxygen-concentration detecting cell 7 correspondingly to the oxygen concentration of a gas to be measured introduced to a measuring chamber 2 from a diffusion hole 1 is maintained constant by controlling an impressing voltage on an oxygen ion pump cell 6. Excess oxygen is dipped, and the gas to be measured with a predetermined oxygen concentration is diffused from a diffusion hole 3 to a measuring cell 4. An voltage is impressed on both electrodes of an oxygen ion pump cell 8, excess oxygen is further dipped, and an NOx gas is dissolved into N2 +O2 by the catalytic action of the electrodes. This O2 is turned into ions and transferred in the solid electrolyte layer of the oxygen pump cell 8, and a current corresponding to the amount of a dissolved NOx gas is passed between both electrodes.  By measuring this current, the concentration of an NOx gas is detected. A moisture content is estimated from the value of current of the oxygen ion pump cell 6, and the concentration of gases is corrected by a map created in advance to obtain the accurate concentration of gases.
