Division (b) Adjustment of engine torque due to auxiliaries fitted for the emissions test
United Kingdom
Where auxiliaries are fitted in accordance with Appendix 2 there shall be no adjustment to the maximum torque for the respective test speed taken from the engine mapping performed according to point 7.6.2.
Where, according to points 6.3.2 or 6.3.3 necessary auxiliaries that should have been fitted for the test are not installed, or auxiliaries that should have been removed for the test are installed, the value of T max shall be adjusted by means of equation (6-17).
| T max = T map – T AUX | (6-17) |
with:
| TAUX = Tr – Tf | (6-18) |
where:
is the unadjusted maximum torque for the respective test speed taken from the engine mapping performed in accordance with point 7.6.2
is the torque required to drive auxiliaries that should have been fitted but were not installed for the test
is the torque required to drive auxiliaries that should have been removed for the test but were installed for the test
