An approach to research speed and power modes of operation of the power unit. Research method is based on collecting experimental data on the characteristics of the car, engine running, position controls, etc. with their subsequent processing. During the test, there is a movement of the car along the route corresponding to the actual conditions, and fixing a number of data over short intervals of time. The analysis of the loading conditions of the engine and the transmission of light commercial vehicle in real-world conditions on a given route. Is a method for determining the torque moments on the field and data on crankshaft speed and engine load by bilinear interpolation, as well as its refinement in view of the angular acceleration of the rotating parts. The studies are graphs that clearly reflect the frequency of occurrence of a high-speed and power modes of operation of the engine and transmission when the vehicle under certain conditions. The analysis can be used in the design and calculation of transmission car in optimizing the parameters of the power unit of the car to improve its performance and consumer qualities.
