摘要
The paper describes the measurements of vibroacoustic exhaust locomotive engine signals for misfire phenomenon simulation and some results of their non-linear analysis. The misfire was simulated by disconnection of fuel supply of one cylinder of the engine. The analysis consists of non-linear methods that are based on the deterministic chaos theory. The results of the analysis demonstrate the dominant Lyapunov exponents in the case when all the cylinders at are in operation to be differing considerably from those obtained when one cylinder does not work. The stimulus for our research is expected during nearest years introduction of regulations on limits of combustion gases emission and obligatory on-board diagnostic systems in exhaust locomotives. This fact induced us to perform some experiments on new methods of misfire detection diagnostic. (c) 2004 Elsevier Ltd. All rights reserved.
