Computer Model for Design of Automobile Engines

A computer model for the design of automobile engines is being developed to enable an evaluation of engine concepts for new vehicles. The model automates the design process and helps in the reduction of the product development cycle. The model determines the basic geometry of engine sub-systems (crank-train, valve-train, etc.) and allows simultaneous evaluation of different engine configurations and different arrangements of engine components.

The engine design model consists of two modules. The first module is a computer program that contains design rules and is used to determine the critical geometry of engine components. The second module is CAD (Computer Aided Design) software that uses geometry data from the first module for generation of parametric 3-d solid models of engine components. By simple changes in geometry of components a new 3-d engine configuration is generated and available for evaluation and analysis of component dimensions, masses and other desired properties.
