Apparatus for evaluating an oxygen sensor.

摘要

An apparatus for evaluating an oxygen sensor includes a device for mixing a fuel and an oxygen-containing gas in an appropriate ratio to prepare a fuel mixture. A burner is connected to the mixing device for burning the fuel mixture to produce a gaseous combustion product. A tubular member extends from the burner for supplying the combustion product. A nozzle is connected to the tubular member for introducing a fuel and an oxygen-containing gas into the tubular member so that the combustion product may have a desired excess air ratio (air-fuel ratio) and a mounting device of the sensor to be evaluated is disposed, at a point downstream of the nozzle, on the tubular member.
