Scope This Regulation applies to the representation of the curve as a function of engine or motor speed of the power at full load indicated by the manufacturer for internal combustion engines or electric drive trains and the maximum 30 minutes power of electric drive trains intended for the propulsion of motor vehicles of categories M and N1.

7 The internal combustion engines belong to one of the following categories: Reciprocating piston engines (positive-ignition or compression-ignition), but excluding free piston engines; Rotary piston engines (positive-ignition or compression ignition); Naturally aspirated or supercharged engines. The electric drive trains are composed of controllers and motors and are used for propulsion of vehicles as the sole mode of propulsion. 2. Definitions "Approval of a drive train" means the approval of a drive train type with regard to its net power measured in accordance with the procedure specified in Annexes 5 or 6 to this Regulation; "Drive train type" means a category of an internal combustion engine or an electric drive train for installation in a motor vehicle which does not differ in such essential characteristics as those defined in Annexes 1 or 2 to this Regulation.

8 "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 listed in Table 1 of Annex 5 or in Annex 6 to this Regulation, and determined under reference atmospheric condition; "Maximum net power" means the maximum value of the net power measured at full engine load; "Maximum 30 minutes power" means the maximum net power of an electric drive train at DC voltage as defined in paragraph of this Regulation, which a drive train can deliver over a period of 30 minutes as an average; "Hybrid vehicles (HV )": "Hybrid vehicle (HV)" means a vehicle with at least two different energy converters and two different energy storage systems (on vehicle) for the purpose of vehicle propulsion.

9 1 As defined in the Consolidated Resolution on the Construction of Vehicles ( ), document ECE/ , para. 2. - E/ECE/324 E/ECE/TRANS/505 5 "Hybrid electric vehicle (HEV)" means a vehicle that, for the purpose of mechanical propulsion, draws energy from both of the following on-vehicle sources of stored energy/power: - A consumable fuel; - An electrical energy/power storage device ( : battery, capacitor, flywheel/generator ..); For a hybrid electric vehicle the "power train" comprises a combination of two different drive train types: - An internal combustion engine; and - One (or several) electric drive train(s); "Standard-production equipment" means equipment provided by the manufacturer for a particular application; "Dual-fuel engine" means an engine system type approved according to Regulation No.

10 49 or mounted on a vehicle type approved with regards to its emissions according to Regulation No. 49 and that is designed to simultaneously operate with diesel fuel and a gaseous fuel, both fuels being metered separately, where the consumed amount of one of the fuels relative to the other one may vary depending on the operation; "Dual-fuel vehicle" means a vehicle that is powered by a dual-fuel engine and that supplies the fuels used by the engine from separate on-board storage systems.
