Reduction in losses accompanying the operation of IC engine requires previous identification of their sources and estimation of their value. Reduction in friction losses that is the most important component of the resistance to motion is particularly substantial. In following study the authors presented the best known methods of friction losses estimation pointing out their advantages and shortcomings. In authors’ opinion the method of balance of torques generated during engine run is the most accurate one. The basic source of error in this method is an additional torque due to the torsional vibrations. Finally, torsional vibrations calculations concerning the VWR5 TDI diesel have been presented as an example.
