The paper presents designing of a robust fault diagnosis system for a catalytic cracking process using artificial neural networks. Identification of the considered process is carried out by using recurrent neural networks. To achieve a robust fault diagnosis system, an uncertainty associated with the model is also taken into account. Neural version of the Model Error Modelling is used to deal w...

Installing a catalytic converter in the exhaust is typical method of reducing engine emissions. Catalytic converters have been shown to lower pollutants while enhancing performance. The influence number brass catalyst plates (Cu-Zn) on Performance commercial Yamaha Jupiter MX motorcycle manufactured 2007 was investigated this study. installed motorbike exhaust, with varying between 5 and 8, con...

During the development of a model equipped with dual VVT engines, higher temperature catalyst was discovered. Therefore, sweep point is optimized under low speed and high load conditions. The test results show that has significant effect on catalytic converter, converter decreased after optimization. At same time, opening little dynamics. In addition, an knocking tendency engine. When increases...

In this paper we prove the existence and uniqueness of the solution of a non-stationary problem that modelizes the behaviour of the concentrations and the temperature of gases going through a cylindrical passage of an automotive catalytic converter. This problem couples parabolic partial differential equations in a domain with one parabolic partial differential equation and some ordinary differ...
