“…Student A began working on this project after helping with a study of the speciated hydrocarbon emissions from small utility engines operating under different fuels. 10 As an undergraduate student working on this project, he was primarily responsible for the coordination of our laboratory tests with field tests being organized by one of the industrial sponsors of the project. This led to the development of an in-laboratory test that mimicked the life cycle of the engines in actual field use.…”

“…degree. Initially, his work as an undergraduate was in support of another small engines emissions project, the details of which can be found in Reisel, et al(2000) 10 Details of the procedures used in Phase 1 of this project can be found in Caceres, et al 11 Briefly, both side-valve and overhead-valve, air-cooled, sparkignition engines with a nominal power rating of 4.8 kW were tested over a total of 200 hours. The nominal lifetime of these engines is 125 hours, but similar engines have longer nominal lifetimes, and it is expected that most users will operate the engines longer than 125 hours.…”

Over the last ten years, a research project involving the study of the air pollutant emissions from small utility engines has been conducted. The project studied (1) the extent of the deterioration of the emissions as the engines age, (2) the causes of the deterioration, and (3) strategies for improving the emissions. Thirteen undergraduate students have worked on this project over the years. In comparison, only two M.S.-level graduate students (one of whom originally worked as an undergraduate student on the project) worked on the project over the same time. As a result, much of the research work was completed by these undergraduate students and their efforts played a large role in sustaining the project over its duration. Students who worked on this project benefited by performing engineering work in a modern research laboratory facility, thereby gaining experience that could be helpful for them in their future careers. In addition, the students had the opportunity to work with engineers from the industrial sponsors of the project. In these interactions, the students needed to learn how to work with other engineers, and communicate their questions, ideas, and results clearly. The reliance on undergraduate students, rather than graduate students, on the project did have some drawbacks. These include an increased need for guidance, and often an increased time for the completion of project tasks due to the students having less time to devote to the project. This paper describes the research activities of the students on the project, and contains a summary of the results. The educational benefits experienced by these students are described. In addition, project management issues such as maintaining project continuity, interaction with the project sponsors, and student recruitment are discussed. Some consideration on the impact of the project on future graduate school enrollment by the students is also presented.

In this study, a laboratory test procedure to mimic the life cycle of the small air-cooled engines in field operation is developed. A characterization of exhaust emissions over the life cycle of the engines is achieved with special focus given to the hydrocarbon emissions. Both Briggs and Stratton four-stroke (four-cycle) overhead-valve and side-valve engines with a nominal power output of 3.7 kW (5 hp) are used in this study. Different levels of emissions are observed for each type of engine configuration, and it is noted that the hydrocarbon emissions changed more than CO or NOx emissions. These data support the idea that combustion chamber deposits (CCD) are a significant cause of deteriorating emissions. Chemical analysis techniques are applied to the CCD, and it is found that the deposits consist primarily of polynuclear aromatic compounds and unsaturated hydrocarbons.
