Specific provisions on total hydrocarbon (HC) limits for fully and partially gaseous-fuelled engines U.K.

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: U.K.

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.

2. For sub-categories with a combined HC and NO_x limit, the combined limit value for HC and NO_x shall be reduced by 0,19 g/kWh and apply for NO_x only. U.K.

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