Verfahren zum Bestimmen der Brutto-Motorleistung eines Kraftfahrzeuges auf einem Rollen-Prüfstand und Rollen-Prüfstand zur Durchführung dieses Verfahrens

摘要

The method involves measuring the nett power delivered to the driven wheels (6,7). The drive train power loss is then measured and added to the wheel power. The power loss is determined by driving the test bed rollers (2-5) at the same speed at which the wheel power is measured with the vehicle engine decoupled and measuring the roller drive power corresponding to the power loss.
