Effective vibration analysis of IC engines using cyclostationarity. Part II - New results on the reconstruction of the cylinder pressures

摘要

This part addresses the feasibility of reconstructing the pressure trace in IC engine from non-intrusive structural vibration measurements by means of an optimal inverse filter. The problem is formally phrased into the general framework of cyclostationary processes introduced in Part I of this paper. It is proved that the optimal inverse filter is periodically varying. A number of guidelines are given for efficiently applying the proposed deconvolution scheme. (C) 2002 Elsevier Science Ltd. All rights reserved. [References: 15]
