Combustion engines are commonly used in car propulsion systems. They belong to a group of heat engines, i.e. those that convert the heat obtained from combustion of liquid or gaseous fuels into mechanical work. Engine parameters, such as power output (Pd ), torque (Ttq) and adaptability to variable traffic [motion] conditions, represent vehicle motion and its functional properties. The torque (Ttq) and the crankshaft speed (n) are measured directly with the use of dynamometer at specific measurement conditions but the power (Pd ) is determined indirectly. The relationships between these parameters are presented using external characteristics. They allow determination of engine adaptability to changes in the resistance to motion, i.e. its flexibility (E). In the paper, flexibility and analytical determination of the power and torque curves through application of Leidemann’s formulas are discussed. Results of the research conducted with the use of turbocharged compressionignition engine equipped with Common Rail fuel system are presented. The correlation between the power and torque curves based on Leidemann’s formulas and the real curves obtained on the basis of experimental research (with application of engine dynamometer) are verified. Finally, evaluation of the method applied for determining the power curves by the speed range of FIAT 1.3 JTD engine was made.
