Abstract In normal case of test bench the combustion engine is connected to a water or eddy current brake. A couple of stationary operating points is measured and the engine chart (M, n-Diagram) is displayed, mostly showing be - const. lines (shell diagram). The engine is considered to work "stand alone ", sometimes a brake mode M - a *n2 may simulate a ship 's propeller. In our application used for student's instruction the real engine on the test bench is connected to a virtual vehicle. Because of its driving resistance characteristics a brake mode M = a *n2 + b is necessary, which a brake normally cannot achieve. For the transfer of vehicle 's driving resistance lines from the driving chart (F, ni-Diagram) to the engine chart gear transmission ratios, dynamic wheel radius and measured driving resistance characteristics must be known. A computer program calculates the suitable torque value, which is supplied to the brake control. The brake is operated in the n = const. mode. By this procedure the road consumption of the simulated vehicle can be determined.
