Definitions
Article 2
For the purposes of this Regulation, the following definitions shall apply: (1) ‘vehicle type with regard to emissions’ means a group of vehicles which: (a) do not differ with respect to the criteria constituting an ‘interpolation family’ as specified in paragraph 6.3.2 of UN Regulation No 154; (b) fall in a single CO 2 interpolation range within the meaning of paragraph 2.3.2 of Annex B6 to UN Regulation No 154 or paragraph 4.5.1 of Annex B8 to UN Regulation No 154; (c) do not differ with respect to any characteristics that have a non-negligible influence on tailpipe emissions, such as, but not limited to, the following: — types and sequence of pollution control devices (e.g. three-way catalyst, oxidation catalyst, lean NOx trap, SCR, lean NOx catalyst, particulate trap or combinations thereof in a single unit), — exhaust gas recirculation (with or without, internal/external, cooled/non-cooled, low/high/combined pressure); (2) ‘periodically regenerating system’ means an exhaust emissions control device (e.g. catalytic converter, particulate trap) that requires a periodic regeneration process; (3) ‘mono fuel vehicle’ means a vehicle that is designed to run primarily on one type of fuel; (4) ‘mono fuel gas vehicle’ means a mono fuel vehicle that is designed primarily for permanent running on LPG or NG/biomethane or hydrogen, but may also have a petrol system for emergency purposes or starting only, where the nominal capacity of the petrol tank does not exceed 15 litres; (5) ‘bi fuel vehicle’ means a vehicle with two separate fuel storage systems that is designed to run primarily on only one fuel at a time, however, the simultaneous use of both fuels is permitted in limited amount and duration; (6) ‘bi fuel gas vehicle’ means a bi fuel vehicle where the two fuels are petrol (petrol mode) and either LPG, NG/biomethane, or hydrogen; (7) ‘flex fuel vehicle’ means a vehicle with one fuel storage system that can run on different mixtures of two or more fuels; (8) ‘flex fuel ethanol vehicle’ means a flex fuel vehicle that can run on petrol or a mixture of petrol and ethanol up to an 85 per cent ethanol blend (E85); (9) ‘malfunction indicator’ or ‘MI’ means a visible or audible indicator that clearly informs the driver of the vehicle in the event of a malfunction of any emission-related component connected to the OBD system, or of the OBD system itself; (10) ‘deficiency’ means, in the context of the OBD system, that up to two separate components or systems which are monitored contain temporary or permanent operating characteristics that impair the otherwise efficient OBD monitoring of those components or systems or do not meet all of the other detailed requirements for OBD; (11) ‘net power’ means the power obtained on a test bench at the end of the crankshaft or its equivalent at the corresponding engine or motor speed with the auxiliaries, tested in accordance with Annex XX, and determined under reference atmospheric conditions; (12) ‘rated engine power’ (Prated) means the maximum net power of the engine or motor in kW measured in accordance with the requirements of Annex XX; (13) ‘maximum 30 minutes power’ means the maximum net power of an electric drive train at DC voltage as set out in paragraph 5.3.2 of UN Regulation No 85 ( 12 ) ; (14) ‘Portable Emissions Measurement System’ or ‘PEMS’ means a portable emissions measurement system meeting the requirements specified in Annex 4 to UN Regulation No 168 ( 13 ) ; (15) ‘permeability factor’ or ‘PF’ means the factor determined on the basis of hydrocarbon losses over a period of time and used to determine the final evaporative emissions; (16) ‘Base Emission Strategy’ or ‘BES’ means an emission strategy that is active throughout the speed and load operating range of the vehicle unless an Auxiliary Emission Strategy is activated; (17) ‘Auxiliary Emission Strategy’ or ‘AES’ means an emission strategy that becomes active and replaces or modifies a BES for a specific purpose and in response to a specific set of ambient or operating conditions and only remains operational as long as those conditions exist.
