Abstract

"Fuel efficiency of internal combustion engines long has been a topic of concern. Much effort has been made to optimize the fuel efficiency of large automotive type engines. However, for small engine manufactures subject to tight cost constraints, this has only recently become an area of great focus. A method by which the fuel efficiency of an engine can be improved is through optimization of the intake process. Specifically, reductions in flow losses and the choice of appropriate valve event timings can provide ways to make gains towards more fuel efficient operation. The challenge arises when the focus is on carbureted engines where the flow rate of air and the flow rate of fuel are coupled. At this point, and for the focus of this thesis, it is important to reduce the amount of energy required of the engine to induct the fuel and air mixture. Several experiments and testing methodologies are introduced that look at ways of minimizing these losses, as well as a look at optimizing the timing of valve events for key operating points. A look at how valve timing events effect the distribution of energy throughout the engine using first law principles was also examined"--Abstract, page iii.
