control oriented modeling of mixture formation in MPI engines to predict air-fuel-ratio in transient conditions

In order to fulfill future LEV/ULEV exhaust emission standards, it is necessary to achieve a precise control of the air-fuel ratio under transient conditions especially during the cold start and warm up periods. The objective in this study was to estimate parameters of a fuel delivery model and use them to provide a correct injection compensation strategy.
