# Commission Implementing Regulation (EU) 2017/656 of 19 December 2016 laying down the administrative requirements relating to emission limits and type-approval of internal combustion engines for non-road mobile machinery in accordance with Regulation (EU) 2016/1628 of the European Parliament and of the Council (Text with EEA relevance), Division 2.4.4.3: Engine with greater spread in swept volume per cylinder


Notwithstanding points 2.4.4.1 and 2.4.4.2, engines with a swept volume per cylinder that exceeds the spread defined in paragraphs 2.4.4.1 and 2.4.4.2 may be considered to belong to the same engine family subject to the approval of the approval authority. The approval shall be based on technical elements (calculations, simulations, experimental results etc.) showing that exceeding the spread does not have a significant influence on the exhaust emissions.
