# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 7.7.2.3: Denormalization of engine torque

Extent: E+W+S+N.I.

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):
T ref = %torque × max.torque 100
(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
max.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
