Design Of A Constant Volume Combustion Chamber, John Bono, Collin Gould, Scott Eaton
Thinking Matters Symposium
This project designs a high-temperature, high-pressure fuel injection chamber for the visualization of diesel fuel injection spray patterns. The study and characterization of diesel fuel spray is important for the development of new engine designs and adoption of alternative fuels. In addition, the chamber can be used to support teaching research projects at the University of Southern Maine. A 3-D SolidWorks model is developed to meet visual accessibility and operating temperature and pressure requirements. Three experimental imaging techniques will be compared, with an emphasis on schlieren photography and videography. Data acquisition and controls systems will be developed including digital imaging …

Thinking Matters Symposium
This project develops a dynamic measuring processes and filtering technique to acquire accurate engine thermodynamic data using LabVIEW. A single-cylinder Kohler diesel engine (model KD440) is instrumented with an in-cylinder pressure monitoring transducer to obtain cylinder pressure and volume data as a function of crank angle position. From this data, several calculations will be made using thermal analysis to understand the engine's performance. An additional objective of the project is to increase the efficiency of the engine's air intake system by modifying the current configuration. We show that the monitoring software accurately measures real-time engine efficiency and combustion dynamics enabling …
