Abstract:
A slope Δ t1 HC  in a linear area of sensor output characteristics for a mixed atmosphere of CO and THC and a slope Δ t1 NH  in the linear area of the sensor output characteristics for NH 3  are specified in advance at a time when a time t 1  has elapsed since a start of use of an engine. In performing calibration of an NH 3  sensor when a time t 2  (greater than the time t 1 ) has elapsed, a slope Δ t2 HC  in the linear area of the sensor output characteristics for the mixed atmosphere is specified, a value Δ t2 NH  is calculated from an equation Δ t2 NH =Δ t2 HC /(Δ t1 HC /Δ t1 NH ), and the calculated value Δ t2 NH  is determined as a new slope in the linear area of the sensor output characteristics for an NH 3  gas.

Claim (Index 7):
The ammonia sensor calibration method according to  claim 6 , wherein\n in said steps a) and b-1), said value of said slope \u0394 t1 HC  and said value of said slope \u0394 t2 HC  are specified while maintaining an oxygen concentration of said exhaust gas in a range of 12% to 21% inclusive.
