This engine was designed for use in the research of a high compression, direct injection, spark ignition, methanol fueled engine with a integral injector ignition source insert.  It exhibits some of the desirable traits of both the premixed charge gasoline engine and modern diesel engine.  The 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.
