A Novel Approach to Reduction of Frictional Losses in a Heavy-Duty Diesel Engine by Reducing the Hydrodynamic Frictional Losses

Table 2

Average values of standard deviation of friction coefficient and resistive coefficient for experiments. T20 and T100 represent the values of standard deviation for the reduced set of experiments. T20 and T100 represent the values of standard deviation for all experiments, without reduction in the number of experiments.
