Design and development of a motored optically accessible engine

Miguel Perez Herrera, University of Texas at El Paso

Abstract

All of the work presented in this thesis was performed within the Engines and Alternative Fuels Research Laboratory in conjunction with the NASA Flow and Thermal Imaging Laboratory (NASA FTIL) located within the Mechanical and Industrial Engineering Department at The University of Texas at El Paso (UTEP). For several years now, research has taken place at the UTEP NASA FTIL using a non-motored optical access cylinder for fuel spray research. Investigations were performed in the NASA FTIL with two GDI injectors using axial and horizontal flow visualization and particle image velocimetry (PIV). Fuel impingement studies were also investigated at different simulated piston positions and temperatures. However, these tests never simulated the actual air charge motion that is induced by the piston and valve movement within a real engine. To enable this type of study, a motored engine is required. Furthermore, in order to apply such imaging techniques as PIV, optical access into the cylinder is also required. To provide optical access, a fused quartz glass cylinder was used to simulate an engine cylinder. (Abstract shortened by UMI.)^
