Division 7.7.2.3 Denormalization of engine torque

The torque values in the engine dynamometer schedule of Appendix 3 of Annex XVII. are normalized to the maximum torque at the respective speed. The torque values of the reference cycle shall be denormalized, using the mapping curve determined according to point 7.6.2, by means of equation (6-16):

for the respective reference speed as determined in point 7.7.2.2

Where:

T _ref

is the reference torque for the respective reference speed

F1max.torque

is the maximum torque for the respective test speed taken from the engine mapping performed in accordance with point 7.6.2 adjusted where necessary in accordance with point 7.7.2.3(b)

%torque

is the value of NRTC or LSI-NRTC normalized torque taken from Appendix 3 of Annex XVII
