Students engage in the analysis, testing, and evaluation of internal combustion engines and their subsystems with a goal toward understanding the principles affecting performance and efficiency. Spark ignition and compression ignition engine systems are studied in detail, with laboratory events designed to connect theory and practice. Material explores modern technologies in use and under development which function to increase powerplant efficiency and decrease emissions. A series of design problems is interspersed throughout the course along with a semester long engineering design project.
