Description

The focus of this research is to study the effects of raising the volumetric efficiency of an E-85 fueled, 4- stroke, single cylinder engine via means of turbocharging. With the increasing demand for efficient engines, this study coincides with what all major auto manufacturers are doing. Small displacement, turbocharged engines are becoming more and more prevalent in today‘s automotive world because of their excellent power output-to-displacement ratio and we were able to study and verify the reasons why these kinds of engines are becoming more popular. Pro/Engineer 3D modeling software was used to model parts of a turbo system to be installed on a 510cc single cylinder engine. The 3D models were then imported into CFDesign software to analyze airflow characteristics through various parts of the turbo system. After the pieces were modeled and analyzed using computer software, the system was implemented on the 510cc engine and tested on a Superflow SF-902 engine dynamometer. To better control the combustion process, electronic fuel injection and ignition systems were used to allow precise adjustments to the amount of fuel entering the engine and when it is ignited.
