Determination of the course of pressure in an internal combustion engine cylinder with the use of vibration effects and radial basis function - Preliminary research

Abstract

A huge development of new technologies applied in the automotive industry has been observed in recent years. It is visible both in designing, manufacturing and operating new means of transport. All over the world, a number of research institutions deal with such issues. Currently, there are many tests in progress on the development of internal combustion engines which are all mainly conditioned by ecological aspects. All that is aimed at designs which are the most eco-friendly and at the same time which have the best technological parameters. To maintain a proper functioning the presently produced engines are controlled with a lot of electronic sensors installed in the vehicle. In the test, an attempt was made to determine the course of internal combustion pressure in a cylinder on the basis of registered vibration signals. Radial neural networks taught using the data achieved from the decomposition with the application of a discrete wavelet transform were used in this test. © 2012 Springer-Verlag.
