Description

The purpose of researching the effects of varying air flow velocity on engine behavior is to increase the overall efficiency and performance of the vehicle. A more efficient engine will require less energy to produce the same desired power output. Unfortunately, improving an engine's performance is a carefully balanced game of compromise. In this case, the research weighs the benefits of restricting air flow to increase air velocity for optimal performance at low rpms. The research is verified in four steps. First, by using an engine simulation software, followed by flow comparison of a stock and modified head. Data is then compared between air velocity on a stock and modified head using an air speed measuring instrument called a Pitot tube. The modified set up is finally tested by comparing the power output of the different cylinder heads while on an engine dynamometer. The data collected from this study will provide further insight into the development of more efficient small engines.
