The paper describes the measurements of vibroacoustic exhaust locomotive engine signals for misfire phenomenon simulation and some results of nonlinear analysis of the given time series. The misfire was simulated by disconnection of one cylinder of the engine. The measurements were performed in Rail Vehicles Institute in Poznań. The analysis, besides the classical methods like spectral analysis, consists of nonlinear methods which are based on the deterministic chaos theory. The stimulus for our researches was expected during nearest years introduction of regulations on limits of combustion gases emission and obligatory on-board diagnostic systems in exhaust locomotives.
