Abstract [en]

It is shown that platinum thin-insula :or-silicon carbide Schottky diodes operated at about 600 degrees C are fast enough to monitor the air fuel ratio in the individual cylinders in the exhaust from a petrol engine. These chemical sensors have time constants of the order of 1 ms. We describe a simple laboratory technique, which can be used to change the gas composition at a chemical sensor within milliseconds. It is based on mechanically oscillating gas outlets placed close to the sensor surface. The properties of and possibilities with such "moving gas outlets" are described.
