Nonlinear Modeling and Simulation of Optimal Decision Making for the ECU of Gasoline Automotive

This paper presents nonlinear modeling for Intake Manifold, Throttle, Compression and Combustion for a gasoline automotive. The differences of this automotive between gaseous automotive and gasoline automotive is discussed. The Backflow model in gaseous state is combined to gasoline automotive model. Cold start, normal, and acceleration as three important stages are discussed in this research. Using pollution and efficiency models and defining a proper cost function, the optimal values of spark times advanced and air to fuel ratios are computed via numerical optimization method. Also in this paper a fuzzy controller is used for recognizing of acceleration and normal stages. The optimal values of spark times advanced and air to fuel ratios are considered corresponding to each stage.
