Stage V engines
The marking must be affixed using a durable method such as printing, stamping, engraving, etc, and shall include, but is not limited to:
- the name, registered trade name or registered trade mark of the engine manufacturer,
- the engine family name (if applicable),
- the engine identification (serial) number and
- either the type-approval number or the mark of the type-approval number.
It is not required for all the information to be contained in a single label or location on the engine. The detailed requirements are set out in Annex III to Implementing Regulation (EU) 2017/656.
For Stage V engines the marking shall include the engine production date (month and year). Alternatively, for engine categories NRSh and NRS, excluding sub-categories NRS-v-2b and NRS-v-3, where engine and non-road mobile machinery are fully integrated and cannot be identified as separate components, it is permitted to use the non-road mobile machinery production date. The markings should be visible when the engine is installed in the machine with only necessary access covers to the engine bay open. Where necessary to ensure the markings are visible when installed, the OEM must ensure that a duplicate label is fitted on the engine or machine to fulfil this requirement.
