The research team uses a GM prototype DISI head mated with a transparent, fused-silica cylinder with a windowed piston, resulting in a geometrically correct engine with multidirectional optical access.
Researchers are able to image the fuel-air mixing process in the cylinder.
By comparing data on the fuel-air mixture quality with performance data from a twin research engine at GM, the researchers are looking for insights into DISI engine design and control.
