Abstract

Internal combustion (IC) engines have been the backbone of modern transportation for over a century. They have played a critical role in shaping how we live and work, powering everything from vehicles and jet engines to generators and industrial machines. The design of engines remains a significant challenge even today because the gas flow in the engine cylinder is unsteady. The number of variables influencing the internal combustion engine makes the development process lengthy and costly. With a simulation technique, engineers and researchers can analyse various engine designs without the expense and time of producing one of the prototypes. Therefore, this research study intends to address these challenges by comparing the performance prediction of two reduced-order engine flow models (simple flow model and Q1D flow model). Modelling of combustion as an instantaneous process provides erroneous results. The rate of heat release is dominant in physics. The Wiebe combustion model seems to provide realistic results. A study comparing the simulation’s predictions to complete dynamometer data could yield a “best” range of values for the Wiebe parameters of ignition start time and combustion duration. Working fluids must be chosen carefully. The result of this research work will help reduce the complexities and challenges encountered in the design and development of internal combustion engines. It will also be beneficial in increasing the efficiency and performance of IC engines.
