Measurements of powertrain power and torque performed on a chassis dyno, on 1 or 2 axles. Measurements performed directly on the wheels, together with measurements of drive system losses, gives the final level of power and torque on the engine output shaft. Measurement range: 0 – 258 kW per axle.
The following measurements can be performed:
- static – at a constant, set speed at one or multiple points, depending on requirements
- dynamic – over the entire vehicle speed range/engine rotational speed range
The results of the measurements are characteristics:
- intermediate – at a constant, set pressure on the accelerator pedal
- external – at maximum pressure on the acceleration pedal, indicating the maximum performance of the powertrain over a given vehicle speed range/engine rotational speed range.
