Abstract


The investigation focus for combustion engines is on reduction of emissions as well as fuel consumption. By introducing the gasoline direct injection combined with downsizing the efficiency and the fuel consumption of gasoline engines has been optimized. An additional potential to the previous solutions provides the water injection. The article include the results of the fundamental research of water injection for combustion engines, it shows the influence of the amount of water in a water-gasoline-emulsion on the spray in a high pressure injection chamber. Therefor the spray of a gasoline direct injection injector is visualized by a high speed camera using the shadowgraph technique.
