Abstract

When analyzing HCCI combustion engine behavior,the integration of experimental tests and numericalsimulations is crucial. Investigations of possible enginecontrol strategies as a function of the different operatingconditions have to take the behavior of the whole HCCIengine into account, including the effects both of thecombustion process and of complex devices. Thereforethe numerical simulation code must be able both to modelaccurately the gas-dynamic of the system and to evaluatethe combustion chemical kinetics.This paper focuses on the coupling between thecommercial one-dimensional fluid-dynamic GT-PowerCode and our in-house detailed chemical kinetic IgnitionCode. An interface has been developed in order toexchange information between the two codes: the IgnitionCode considers as boundary conditions the GT-PowerCode values provided for the gas composition at IVC andthe pressure and temperature at every time step andpasses back to GT-Power the burnt fuel fraction andstores in an external file the in cylinder gas composition.Thus the whole engine cycle can be accurately simulated,estimating the interactions between the gas-dynamicsphenomena along the intake and exhaust pipes andthrough the valves, and the chemical processes occurringduring the closed valves period.This tool makes it possible to analyze the enginebehavior under duty cycle operating conditions, andtherefore it represents a useful support to theexperimental measurements, reducing the number oftests required to assess the proper engine controlstrategies.
