Educational Software to Study Alternative Internal Combustion Engine Cycles

Abstract

This paper illustrates the use of engine modelling in the educational setting through the development and use of software for the simulation of cycles of different internal combustion engines. Modelling and computer simulation of an internal combustion engine's operating processes offer a valuable tool for enhancing understanding of real physical phenomena and contribute significantly to optimizing and controlling the engine's operation to meet different objectives. The paper begins by describing the theoretical models of engine operation. These models are for various fluids: perfect gas, ideal gas and air/fuel mixes; and for constant volume (Otto cycle), constant pressure and mixed (diesel) cycles. The software has been developed to solve many problems and it facilitates understanding of the thermodynamic fundamentals of an internal combustion engine. Overall, this study demonstrates the power of such an engine simulation tool in an educational setting.
