Non-road mobile machinery covers a very wide variety of machinery typically used off the road in many ways. It comprises, for example:

• small gardening and handheld equipment (lawn mowers, chainsaws, etc.)
•  construction machinery (excavators, loaders, bulldozers, etc.)
•  agricultural and farming machinery (harvesters, cultivators, etc.)
•  railcars, locomotives and inland waterway vessels

Emissions from these engines are regulated by a new Regulation which will apply as of 1 January 2017 (NRMM Regulation):

Regulation (EU) 2016/1628 of the European Parliament and of the Council of 14 September 2016 on requirements relating to gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery, amending Regulations (EU) No 1024/2012 and (EU) No 167/2013, and amending and repealing Directive 97/68/EC.

The NRMM Regulation defines emission limits for NRMM engines for different power ranges and applications. It also lays down the procedures engine manufacturers have to follow in order to obtain type-approval of their engines – which is a prerequisite for placing their engines on the EU market.
