operating cycle (or equivalent engine test bench cycle) without regeneration
               M'rij = mass emissions of pollutant (i) in g/km over one Type I operating cycle (or equivalent engine test bench cycle) during regeneration.  (when n>1, the first Type I test is run cold, and subsequent cycles are hot)
               Msi = mean mass emission of pollutant (i) in g/km without regeneration
               Mri = mean mass emission of pollutant (i) in g/km during regeneration
               Mpi = mean mass emission of pollutant (i) in g/km
               n = number of test points at which emissions measurements (Type I operating cycles or equivalent engine test bench cycles) are made between two cycles where regenerative phases occur,  2
               d =  number of operating cycles required for regeneration
               D = number of operating cycles between two cycles where regenerative phases occur

         For exemplary illustration of measurement parameters see Figure 8/1.

         Figure 8/1: Parameters measured during emissions test during and between cycles where regeneration occurs (schematic example, the emissions during 'D' may increase or decrease)

         3.4. Calculation of the regeneration factor K for each pollutant (i) considered

         Ki = Mpi / Msi

         Msi, Mpi and Ki results shall be recorded in the test report delivered by the technical service.

         Ki may be determined following the completion of a single sequence."

EMISSIONS TEST PROCEDURE FOR HYBRID ELECTRIC VEHICLES (HEV)

         1. INTRODUCTION

         1.1. This Annex defines the specific provisions regarding type-approval of a hybrid electric vehicle (HEV) as defined in paragraph 2.21.2. of this Regulation.

         1.2. As a general principle, for the tests of Type I, II, III, IV, V, VI and OBD, hybrid electric vehicles shall be tested according to Annex 4, 5, 6, 7, 9, 8 and 11 respectively, unless modified by this Annex.

         1.3. For the Type I test only, OVC vehicles (as categorized in paragraph 2) shall be tested according to condition A and to condition B.  The test results under both conditions A and B and the weighted values shall be reported in the communication form.

         1.4. The emissions test results shall comply with the limits under all specified test conditions of this Regulation.

         2. CATEGORIES OF HYBRID ELECTRIC VEHICLES

         3. TYPE I TEST METHODS

         3.1. EXTERNALLY CHARGEABLE (OVC HEV) WITHOUT AN OPERATING MODE SWITCH

         3.1.1. Two tests shall be performed under the following conditions:

                    Condition A: test shall be carried out with a fully charged electrical energy/power storage device.

                    Condition B: test shall be carried out with an electrical energy/power storage device in minimum state of charge (maximum discharge
