The article describes the features and methods of testing the ATV on a hub dynamometer test bench. The graphs of the test results are presented, and the graphs analyzes, aimed at researching the operation of its engine-transmission bench, is carried out. The change of the gear ratio at different throttle positions is specific. This specific operation characteristic of the V-belt variator used in ATV transmission as a gearboxes found.

The paper discusses issues related to the possibility of obtaining of the value of noise dispersion of towing vehicles by calculation. The authors obtained mathematical expressions to determine the dispersion of depending on confidence interval of individual noise sources. The article shows a general procedure for evaluating of probable dispersion of the results of the estimated noise of a vehicle.
