Abstract
A new method for the evaluation of fast gas sensors is described. By using moving gas outlets, we can quickly change the ambient around a sensor. Diff erent platinum-insulator-silicon carbide (MISiC) structures are investigate d. Their sensor response contains fast components, which respond within mil liseconds to a change in the ambient from a reducing gas to an oxidising ga s and vice versa. Cylinder specific monitoring of car engines with the MISi C structures is discussed. (C) 1999 Elsevier Science S.A. AU rights reserve d.
