Commission Regulation (EU) 2018/932
of 29 June 2018
amending Regulation (EU) No 582/2011 as regards the provisions on testing by means of portable emission measurement systems (PEMS) and the requirements for universal fuel range type-approval
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC1, and in particular Article 5(4) thereof,
Whereas:
CEN standards for certain common Fatty Acid Methyl Ester (FAME) diesel blends and paraffinic diesel have recently been published. Therefore, it is appropriate to update the current rules to refer also to those new standards.
In relation to testing with portable emission measurement systems (PEMS), Commission Regulation (EU) 2016/17182 introduced requirements on both urban trip share as well as the total trip length. Especially on some N3 category vehicles equipped with an engine with higher power rating, it has been discovered that, due to those limiting requirements, PEMS testing in accordance with the current provisions will result in void tests. In order to resolve the issue, the conditions for compliance with the urban window requirement should be amended, with the urban trip being enlarged at the expense of the motorway trip share and the maximum overall trip length extended.
Clarification is needed regarding the requirement to have at least one valid window in urban only operations applying to NOx emissions specifically, as it is the critical polutant in those conditions.
In case of universal fuel range type-approval, the procedure for demonstrating compliance with the required tolerances for the engine control unit (ECU) torque signal is currently not set out in Commission Regulation (EU) No 582/20113. Therefore, when the engine is not equipped with a system to recognise which fuel is being used, the demonstration on how to determine compliance is up to the discretion of the technical service. Due to the increasing interest in type approval of alternative fuels, it is appropriate to harmonise that procedure. The torque deviation caused by the alternative fuel should therefore be determined and the deviation should then be used to calculate a power correction factor, which should be stated in the type approval documentation. The power correction factor may be applied to demonstrate compliance with the ECU torque signal accuracy requirements. Moreover, for PEMS testing with an alternative fuel, the power correction factor may be applied to determine the correct torque value for emission calculations.
Regulation (EU) No 582/2011 should therefore be amended accordingly.
The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,
