Designers of gasoline engines are faced with higher and higher requirements as regards ecological problems and increase in engine efficiency at a simultaneous decrease in fuel consumption. Satisfaction of these requirements is possible due to recognition of the phenomena occurring inside the engine cylinder, choice of suitable optimal parameters of the fuel injection process, and determination of geometrical shapes of the combustion chamber and piston head. The paper presents analysis of increasing in general efficiency of a GDI (Gasoline Direct Injection) engine in dependence on the quality of the stratified mixture and range of loading. For determination of total efficiency of a Gasoline Direct Injection engine test bed investigations were carried out with the aim to determinate the speed and load characteristics of the investigated engine on these basis the total efficiency of a GDI engine can be determined.
