ABSTRACT

The strong tendency in the automotive industry to reduce development time through virtual prototyping and optimization of design using simulation tools implies that engineers need to be proficient in using sophisticated simulations. At the same time, engineers also need to have a solid understanding of the underlying physics in order to be able to interpret the results correctly and communicate them to fellow team members. The availability of multimedia equipment in the classroom provides an opportunity to use computer simulations as a direct aid in teaching advanced modeling concepts to professional engineers. This paper presents the results of the adaptation of a suite of internal combustion engine simulations in a graphical software environment suitable for use in the multimedia teaching environment for continuing education. Within the context of a one-week intensive short course, the graphical user interface allows easy manipulation of input parameters, monitoring of selected output variables in real time and visual representation of results obtained through multiple runs for comparative studies. Our experience based on a first offering of the course indicates that simulations implemented in a graphical environment can greatly increase the effectiveness of the teaching process, especially under the constraints of a one-week intensive short course.

1. INTRODUCTION

Modeling of internal combustion engines is an integral part of studying the fundamentals of processes that take place within the engine cylinder, as well as phenomena occurring in the complex engine system such as the typical turbocharged multi-cylinder engine configuration. During the course of years, a large body of engine simulations has been developed for research purposes with a high degree of sophistication and hence fidelity. Such research codes have been successfully introduced by Professor Assanis in an advanced graduate level, mechanical engineering course on Internal Combustion Engines that he has developed and taught since 1986 at the University of Illinois in Urbana-Champaign (ME 445) and the University of Michigan in Ann Arbor (ME 534). Students have repeatedly expressed favorable feedback on the value of transitioning the research tools into the classroom, thus enabling them to conduct real-life,
