Abstract

This paper discusses the development of an integrated tool for the design, optimization and real-time control of engines from a performance and emissions standpoint. The design tool consists of two coupled modules, namely, an engine module and an optimization module. The engine module consists of three components, namely, a two-zone quasi-dimensional engine model to compute the temporal variation of temperature and pressure during the compression and power stroke, a thermal model to compute the cyclic variation of the engine wall temperature, and a reaction-rate-controlled emission model to compute engine-out NO and CO. The optimization solver is an extension of the model-based derivative-free POUNDER, and is designed to limit the number of engine model evaluations. The outputs of the engine model, thermal model, and emissions model can be used for optimizations under various design constraints.
