Direct injection of gasoline fuel has been gaining on applicability in recent years. Direct injection spark ignited engine has been one of the most investigated designs for achieving lower fuel consumption and for increasing the performance. Maintaining low emissions, decreasing fuel consumption and keeping driving performance are key challenges. Fuel injection quality is one of the most important factors, which directly affect general engine requirements like fuel mass flow, spray penetration and atomization for the combustion process. The multi-hole injector design is a very promising design type for application in direct fuel injection in automotive petrol engines. As a consequence of decreasing supplies of fossil fuels, mixing of different fuel components has become very common in recent years. The type of components which are to be mixed depends on local geographical fuel availability and motorization type.
