“…Some constraints result in a direct solution to specific variables, while the remaining constraint equations must be solved iteratively. For inflow, conservation of mass and energy equations provide three 10 Modelling and Simulation in Engineering constrains. Isentropic assumptions and conservation of momentum provide the remaining relationships.…”

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

“…Most of the currently available 1D physics-based engine simulation tools are not compatible with or directly implemented in the prevalent MATLAB/Simulink simulation environment. To resolve this deficiency, a high-fidelity physics-based engine simulation modeling framework has been developed in MATLAB/Simulink recently [14][15][16]. Among the various components in the framework, modeling details of the 1D intake and exhaust flow dynamics were presented in a previous publication [17] based on the work of Blair [18].…”

An internal combustion engine modeling framework has been developed in the MATLAB/Simulink environment to allow engine component blocks to be connected in a physically representative manner to reduce the model build time. Each component block, derived from physical laws, interacts with other blocks according to block connection. In this series paper, detailed combustion modeling is presented among several engine subsystems. In the engine modeling framework, combustion is represented by a spherical flame propagating from the spark plug, and the burn rate is correlated to combustion chamber geometry, laminar flame speed, and turbulence. To accurately predict the burn rate, the quasi-dimensional model requires tuning. The combustion model has been computationally validated in a previous study and will be experimentally validated with real engine test data in the next series paper.
