Continuous determination of inner pressure curve of piston engine esp. IC engine

摘要

The results obtained are so processed in steps across a mathematical correction and standardising model working in conjunction with a computer. That a signal curve is derived, equivalent to the inner pressure curve of the IC engine. The inner pressure curve is detected at the same time with the reacting displacement, speed or acceleration signal, for the single calibration of a correction model. Also with the use of the inner pressure curve, as an excitation variable across a discrete transient analyser, describing the component system, the theoretical movement course of the components is determined. So that as a result a computed displacement, speed or acceleration signal free of outside interference influences, is given.
