With the increasing awareness of the effects of engine exhaust emissions on human health and the environment, emission legislation has continuously been tightened for all internal combustion engines, including engines for NRMM. Figure 1 shows the development of emission limits for NRMM, starting with the EU Stage I legislation in 1999 up to the planned implementation of the EU Stage V emissions in 2019. Nitrogen oxide (NOx) and particulate matter (PM) emissions will have been reduced by more than 95 % in this time span of nearly 20 years. Similarly, stringent emission standards have been introduced in the other triad nations as well. Emerging markets like China and India are catching up with the stringent emission limits of EU and the USA.
