# Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance), Division 3.6: Transmission Power Take-Off (PTO)

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

For vehicles with PTO and/or PTO drive mechanism installed on the transmission, the power consumption shall be considered by determined standard values. The corresponding standard values represent these power losses in usual drive mode when the PTO is switched off/disengaged. Application related power consumptions at engaged PTO are added by the simulation tool and are not described in the following.
