PARAMETRIC STUDY OF INTERNAL COMBUSTION ENGINE

Abstract

The objective of this study is to validate simulation model with the experimental setup data and to analyze engine operating parameters at different RPM, Air/Fuel Ratio, intake pressure, compression ratio and valve lift for the optimization of engine for better performance. A test bench containing a diesel engine was used to collect experimental data on different operating parameters on different test points using sensors. On the other hand, a software model was designed using Ricardo WAVE for obtaining simulation results on the test points similar to experimental data. Aim of this study is to design a software model validating experimental data which leads towards obtaining optimum operating parameters and improvement in engine design. Another benefit of this study is that software tuning of engine becomes relatively easier as sometimes experimental tuning is difficult due to various design constraints which limits the changes required in parameters for tuning. This research will be helpful in designing engines with better performance and emissions.
