Abstract
A stratified charge research engine and test stand were designed and built for this work. The engine was designed to exhibit some of the desirable traits of both the premixed charge gasoline engine and modern diesel engine. This spark ignition engine is fueled by M100 (99.99% pure methanol), operates under high compression (19.3:1) and uses direct fuel injection to form a stratification of the fuel-air mixture in the cylinder. The beginning of the combustion event of the stratified mixture is triggered by spark plug discharge. The primary goal of this project was to evaluate the feasibility of using a removable integral injector ignition source insert, which allows a convenient method of changing the relative location of the fuel injector to the ignition source, as well as the compression ratio, squish height, and bowl volumes. This paper provides an explanation of the hardware included in the experimental setup of the engine and selection of the direct injector configuration. Upon setup completion, performance results were measured from three combustion chamber/injector configurations, and preliminary results are presented.
