Specific provisions on hydro-carbon (HC) limits 
for fully and partially gaseous fuelled engines 
1. For the sub-categories where an A factor is  defined, the HC limit for fully and partially 
gaseous fuelled engines indicate d in the table is replaced by the one calculated with the 
following formula: 
 HC = 0,19 + (1,5*A*GER)  where GER is the average gas energy ratio ove r the appropriate cycle. Where both a steady-
state and transient test cycle applies, the GER sh all be determined from the hot-start transient 
test cycle. Where more than one steady-state te st cycle applies, the average gas energy ratio 
shall be determined for each cycle individually. 
If the calculated limit for HC exceeds the valu e of 0,19 + A the limit for HC shall be set to 
0,19 + A.

Figure 1. Schematic of HC emission limit as function of average ga s energy ratio (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 engine s the formula does not apply.
