Friction losses generated in engine kinematic nodes have an essential effect on its general efficiency. Measurement of these losses and indication of areas where they are generated can contribute to their minimization at the stage of engine design and during its operation as well. Most of the loss measurement methods requires an intervention in engine construction. The method of engine motoring does not require such intervention and at the same time offers possibility of precise measurement of engine resistance. The results obtained with the use of this method are considered hardly precise (among others because of different conditions during engine normal operation and its motoring), nevertheless they allow to estimate the influence of various effects on resistance observed on an engine. This study presents the results of tests on the effect of certain quantities characteristic for engine operation as well as properties of lube oil applied on the course of instantaneous values of motored engine torque. Another achievement of the study is the recommendation of test conditions securing highest possible accuracy of engine resistance torque determination. The simulation tests were carried out on the 170A.000 engine.
