Non-road fuel consumption and pollutant emissions FOEN 2008 88 8.5.2 Emissions Petrol engines above all produce high levels of carbon monoxide and hydrocarbon emissions (Fig. 45, top). 2-stroke engines account for 72% of HC emissions, despite the fact that they only account for 35% of fuel consumption. Development of pollutant emissions from 1980 to 2020 A pronounced decrease in hydrocarbon emissions is to be anticipated over the next few years, since the more stringent EU exhaust regulations will mean that new engines will emit lower levels (Fig. 45, bottom right). This tightening of emission limit values, which only applies within the EU, will also mean that 4-stroke engines will increasingly replace 2-stroke engines, so that the inventory of the latter will decrease. With respect to carbon monoxide, the decrease in emissions over the next few years is expected to be relatively modest.
