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. Figure 1. Diagram showing HC emission limit as function of average GER 2. For sub-categories with a combined HC and NOx limit, the combined limit value for HC and NOx shall be reduced by 0,19 g/kWh and apply for NOx only.

3. For non-gaseous-fuelled engines, the formula does not apply.
