With advancements in computer-aided design, simulation of internal combustion engines has become a vital tool for product\ndevelopment and design innovation. Among the simulation software packages currently available, MATLAB/Simulink is widely\nused for automotive system simulations, but does not contain a comprehensive engine modeling toolbox. To leverage\nMATLAB/Simulinkâ??s capabilities, a Simulink-based 1D flow engine modeling framework has been developed. The framework\nallows engine component blocks to be connected in a physically representative manner in the Simulink environment, reducing\nmodel build time. Each component block, derived from physical laws, interacts with other blocks according to block connection.\nIn this Part 1 of series papers, a comprehensive gas dynamics model is presented and integrated in the engine modeling\nframework based on MATLAB/Simulink. Then, the gas dynamics model is validated with commercial engine simulation\nsoftware by conducting a simple 1D flow simulation.
