Division 1 For the sub-categories where an A-factor is defined, the HC limit for fully and partially gaseous-fuelled engines indicated in Tables II-1 to II-10 is replaced by a limit calculated using the following formula:

HC = 0,19 + (1,5 × A × GER)

where GER is the average gas energy ratio over the appropriate test cycle. Where both a steady-state and transient test cycle apply, the GER shall be determined from the hot-start transient test cycle. Where more than one steady-state test cycle applies, the average GER shall be determined for each cycle individually.

If the calculated limit for HC exceeds the value of 0,19 + A, the limit for HC shall be set to 0,19 + A.
