Sequence for thermal ageing

Mode Speed (% of high idle) Load (% for a given speed) Time (s)
1 2,92 0,58 626
2 45,72 1,58 418
3 38,87 3,37 300
4 20,23 11,36 102
5 11,37 14,90 62
6 32,78 18,52 370
7 53,12 20,19 410
8 59,53 34,73 780
9 78,24 54,38 132
10 39,07 62,85 212
11 47,82 62,94 188
Regeneration mode (if applicable) To be defined (see point 2.4.3.4) To be defined (see point 2.4.3.4) To be defined (see point 2.4.3.4)
Lubricant consumption mode (if applicable) To be defined according to point 2.4.4.8.2 To be defined according to point 2.4.4.8.2 To be defined according to point 2.4.4.8.3

Note:

The sequence of the modes 1 to 11 has been arranged by ascending load in order to maximise the temperature of the exhaust gas in the high load modes. With the agreement of the type-approval authority, this order can be modified in order to optimise the temperature of the exhaust gas if this can help in reducing the actual aging time.
