Optimization of ignition advance angle and air fuel ratio of combustion engines

Abstract

In this paper, the combustion phase optimization is analyzed and ignition timing of SI engines is controlled to maximize the fuel efficiency. Particularly,the optimum set point of the combustion phase and moving average based control strategy are discussed to extract information about the fuel efficiency from the combustion. The purpose of this study is to optimize the ignition advance angle and air fuel ratio of the motorcycle engine to get maximum brake torque. We use Matlab to solve the problem of the ignition angle based on the model of combustion engine. The optimization algorithm used for the two input variables is Air fuel ratio and ignition advance angle. For the internal combustion engine model built on Matlab software, it is possible to change the engine parameter structure
