ANALYSIS AND OPTIMIZATION OF SOME OSCILLATION PARAMETERS OF THE THERMAL EXHAUST VALVE SYSTEM MODEL IN INTERNAL COMBUSTION ENGINES

Abstract

The article analyzes the oscillation characteristics of the exhaust valve system in internal combustion engines. By using dynamic analysis methods, the authors established differential equations that describe the system's oscillations. At the same time, the paper proposes an optimization problem aimed at reducing the decay time of the oscillations and controlling the oscillation amplitude within allowable limits. An optimization algorithm employing a Genetic Algorithm (GA) is used to optimize the system's parameters, thereby minimizing the coupling between different oscillatory components. The results indicate that the optimized parameters can significantly reduce the interactions among individual oscillations, which in turn enhances the overall stability of the system.
