This anne efines the specific provions regaring type approval of a vehicle equippe with a perioically regenerating system as efine in paragraph.6. of this Regulation.. Scope an etenon of the type approval.. Vehicle family groups equippe with perioically regenerating system The proceure applies to vehicles equippe with a perioically regenerating system as efine in paragraph.6. of this Regulation. For the purpose of this anne vehicle family groups may be establishe. Accoringly, those vehicle types with regenerative systems, whose parameters escribe below are ientical, or within the state tolerances, shall be conere to belong to the same family with respect to measurements specific to the efine perioically regenerating systems.... Ientical parameters are: Engine: (a) (b) (c) () (e) Number of cyliners, Engine capacity (±5 per cent), Number of valves, Fuel system, Combustion process ( stroe, 4 stroe, rotary). Perioically regenerating system (i.e. catalyst, particulate trap): (a) (b) (c) () (e) Construction (i.e. type of enclosure, type of precious metal, type of substrate, cell enty), Type an woring principle, Dosage an aitive system, Volume (±0 per cent), Location (temperature ±50 C at 0 m/h or 5 per cent ifference of maimum temperature / pressure)... Vehicle types of ifferent reference masses The K i factor evelope by the proceures in this anne for type approval of a vehicle type with a perioically regenerating system as efine in paragraph.6. of this Regulation, may be etene to other vehicles in the family group with a reference mass within the net two higher equivalent inertia classes or any lower equivalent inertia.

3 E/ECE/34/Rev./A.00/Rev./Amen.3 E/ECE/TRANS/505/Rev./A.00/Rev./Amen.3.3. Instea of carrying out the test proceures efine in the following paragraph, a fie K i value of.05 may be use, if the technical service sees no reason that this value coul be eceee. 3. Test proceure The vehicle may be equippe with a switch capable of preventing or permitting the regeneration process provie that this operation has no effect on original engine calibration. This switch shall be permitte only for the purpose of preventing regeneration uring loaing of the regeneration system an uring the pre-conitioning cycles. However, it shall not be use uring the measurement of emisons uring the regeneration phase; rather the emison test shall be carrie out with the unchange Original Equipment anufacturer's (OE) control unit. 3.. easurement of carbon ioie emison an fuel consumption between two cycles where regenerative phases occur 3... The average of carbon ioie emison an fuel consumption between regeneration phases an uring loaing of the regenerative evice shall be etermine from the arithmetic mean of several approimately equiistant (if more than ) Type I operating cycles or equivalent engine test bench cycles. As an alternative, the manufacturer may provie ata to show that the carbon ioie emison an fuel consumption remain constant (+4 per cent) between regeneration phases. In this case, the carbon ioie emison an fuel consumption measure uring the regular Type I test may be use. In any other case emisons measurement for at least two Type I operating cycles or equivalent engine test bench cycles must be complete: one immeiately after regeneration (before new loaing) an one as close as posble prior to a regeneration phase. All emisons measurements an calculations shall be carrie out accoring to Anne 6. Determination of average emisons for a ngle regenerative system shall be accoring to paragraph 3.3. of this anne an for multiple regeneration systems accoring to paragraph 3.4. of this anne The loaing process an K i etermination shall be mae uring the Type I operating cycle, on a chass ynamometer or on an engine test bench ung an equivalent test cycle. These cycles may be run continuously (i.e. without the nee to switch the engine off between cycles). After any number of complete cycles, the vehicle may be remove from the chass ynamometer, an the test continue at a later time The number of cycles (D) between two cycles where regeneration phases occur, the number of cycles over which emisons measurements are mae (n), an each emisons measurement (' j ) shall be reporte in Anne, items to or to as applicable. 3.. easurement of carbon ioie emison an fuel consumption uring regeneration 3... Preparation of the vehicle, if require, for the emisons test uring a regeneration phase, may be complete ung the preparation cycles in paragraph 5.3. of Anne 4 of Regulation No. 83 or equivalent engine test bench cycles, epening on the loaing proceure chosen in paragraph 3... above. 3

4 E/ECE/34/Rev./A.00/Rev./Amen.3 E/ECE/TRANS/505/Rev./A.00/Rev./Amen The test an vehicle conitions for the test escribe in Anne 6 apply before the first vali emison test is carrie out Regeneration must not occur uring the preparation of the vehicle. This may be ensure by one of the following methos: A ummy regenerating system or partial system may be fitte for the preconitioning cycles Any other metho agree between the manufacturer an the type approval authority A col-start ehaust emison test incluing a regeneration process shall be performe accoring to the Type I operating cycle, or equivalent engine test bench cycle. If the emisons tests between two cycles where regeneration phases occur are carrie out on an engine test bench, the emisons test incluing a regeneration phase shall also be carrie out on an engine test bench If the regeneration process requires more than one operating cycle, subsequent test cycle(s) shall be riven immeiately, without switching the engine off, until complete regeneration has been achieve (each cycle shall be complete). The time necessary to set up a new test shoul be as short as posble (e.g. particular matter filter change). The engine must be switche off uring this perio The carbon ioie emison an fuel consumption values uring regeneration ( ri ) shall be calculate accoring to Anne 6.
