The paper presents determination of the total efficiency of GDI Engine working on stratified charge. For the determination of the total efficiency of a Gasoline Direct Injection engine, test bed investigations were carried out with the aim to determine the speed and load characteristics of the investigated engine. On this basis, the total efficiency of a GDI engine can be determined. The results of the performed analysis were given in two-dimensional diagrams. Characteristics of full power and torque in dependence on rotational speed, characteristics of torque for increasingly smaller partial powers in function of rotational speed, characteristics of partial loads r in function of rotational speed, relation of fuel consumption per hour and per unit for full value of rated power in dependence on rotational speed, load characteristics of fuel consumption in function of torque at constant rotational speeds, relation of fuel consumption in function of rotational speed and relation of total efficiency eta0 in function of rotational speed are presented in the paper.
