ANNEX IIISupplementary provisions
ANNEX III Annex III to Delegated Regulation (EU) 2017/654 is amended as follows: (1) points 3.1.3 and 3.1.4 are replaced by the following: ‘3.1.3. The test engine shall represent the emission deterioration characteristics of the engine families that will apply the resulting deterioration factors for type approval. The engine manufacturer shall select one engine representing the engine family, group of engine families or engine-after-treatment system family, as determined in accordance with point 3.1.2, for testing over the service accumulation schedule referred to in point 3.2.2, which shall be reported to the approval authority before any testing commences. 3.1.4. If the approval authority decides that the worst case emissions of the engine family, group of engine families or engine-after-treatment system family can be better characterised by another test engine, the test engine to be used shall be selected jointly by the approval authority and the engine manufacturer.’; (2) point 3.2.1 is replaced by the following: ‘3.2.1. General Deterioration factors applicable to an engine family, group of engine families or an engine-after-treatment system family shall be developed from the selected engines based on a service accumulation schedule that includes periodic testing for gaseous and particulate emissions over each test cycle applicable to the engine category, as given in Annex IV to Regulation (EU) 2016/1628. In the case of non-road transient test cycles for engines of category NRE (“NRTC”), only the results of the hot-start run of the NRTC (“hot-start NRTC”) shall be used.’; (3) in point 3.2.5.2, the last paragraph is replaced by the following: ‘Where emission values are used for engine families in the same group of engine families or engine-after-treatment family but with different emission durability periods, then the emission values at the emission durability period end point shall be recalculated for each emission durability period by extrapolation or interpolation of the regression equation as determined in point 3.2.5.1.’; (4) in point 3.2.6.1, the last paragraph is deleted; (5) the following point 3.2.6.1.1 is inserted: ‘3.2.6.1.1. Notwithstanding point 3.2.6.1, for PN, either an additive DF of 0,0 or a multiplicative DF of 1,0 may be used, in conjunction with the results of previous DF testing that did not establish a value for PN if both of the following conditions are fulfilled: (a) the previous DF test was conducted on engine technology that would have qualified for inclusion in the same engine after-treatment system family, as set out in point 3.1.2, as the engine family to which it is intended to apply the DFs; and, (b) the test results were used in a previous type-approval granted before the applicable EU type-approval date given in Annex III to Regulation (EU) 2016/1628.’.
