The goal of “ETME 499-Independent Research in Mechanical Engineering Technology” course is to introduce students to designing, manufacturing, debugging and testing mechanical systems. The goal of laboratory part of “EDTE 341-Power and Transportation” course is to service small and/or large internal combustion engines. The purpose of this project was to service gasoline engine, service the engine dynamometer, test the system and carry out some engine performance tests. If successful, engine tests will be incorporated into “EDTE 341-Power and Transportation course” or “ETME 301- Thermodynamics and Heat Power” course as one or two laboratory experiments. EDTE 341 course is a technical elective and ETME 301 is a required course in Mechanical Engineering Technology (MET) program. Gasoline engine was disassembled and serviced as a requirement for the laboratory part of EDTE 341 course. Servicing of the engine-dynamometer was completed as an ETME 499 project. Instrumentation for fuel consumption measurements were added and measurements were carried. Results indicate that, at constant load, as engine speed is increased fuel consumption has increased. Same trend is seen at constant speed; fuel consumption has increased as load is increased. Simulated fuel economy (miles/gal) graph indicate that engine is most economical if it is used at about 2500 rpm.
Two Engine-Dynamometer systems to be used for Internal Combustion Engine related courses came with the new building when the department moved into it in 1985. Engines have the same model dynamometers, they were purchased as sets from Megatech Corporation1 and they were never used since 1985. Since the systems were sitting too long I decided to overhaul the gasoline engine when I taught “EDTE 341-Power and Transportation” course few years ago. Engine was opened, cleaned and put together as part of the laboratory requirement for the course. Since dynamometer was leaking fluid, it needed service also. Most of the dynamometer service was completed past summer as part of an “ETME 499-Independent Research in MET” course. Equipment installations and modifications needed for fuel consumption measurements, and fuel consumption measurements have been completed recently.
