In this paper there has been described the structure of ZI gasoline direct injection engines in which there has been applied spray guided. There has been shown the burning chambers structure of the engines of that type. There has been also presented the modification range of ZI engines equipped with system of gasoline multipoint indirect injection in order to get the gasoline direct injection engine with spray guided. The authors have described the block diagram of fuel supply system of this type of an engine which is being developed in Cracow University of Technology's Combustion Engine Department. Certain information about mechanical modification of engine is given. They have proposed model of fuel air mixture stratification in a combustion chamber of spray guided engine, in which base homogeneous mixture come into being out of the this chamber. In this paper there has been also designated an influence of an angle of crank shaft on initial velocity of fuel stream and on flow intensity of fuel stream that flows through the injector. There also has been presented an influence of air fuel coefficient of homogeneous base mixture on the angle on a crank shaft of ignition charge.
