Figure 18: Overview current, proposed emission limits for all L-category vehicle categories vs. passenger car M1 benchmark limits: Total HydroCarbons (THC)

NB. The euro5 reference value for PI engines were arithmetically determined by adding up the separate THC and NOx limits. This was only done to show the order of magnitude and should not be interpreted as absolute limit comparison, unlike the euro5 Diesel passenger car M1 limits, which actually consists of a combined THC&NOx limit and a separate NOx limit.
