During vehicles and their parts testing, measure the large number of parameters, in various modes. All of them are random variables with the characteristics of precision – uncertainty. In engines testing the distributed types of uncertainties are: errors of measuring tools; uncertainty of constants, ratios and amendments; uncertainty of reading the testimony from analog scale devices. The quantifying uncertainty in measurement don’t need to evaluate all influencing factors, but only the necessary and sufficient factors to significantly affect the outcome of tests.
