engine which are connected to the oil sump by internal or external ducts through which gases and vapour can escape.

         2.9. "Cold start device" means a device that temporarily enriches the air/fuel mixture of the engine thus assisting the engine to start.

         2.10. "Starting aid" means a device which assists engine start up without enrichment of the air/fuel mixture of the engine, e.g. glow plug, injection timing change, etc.

         2.11. "Engine capacity" means:

         2.11.1.  for reciprocating piston engines, the nominal engine swept volume;

         2.11.2.  for rotary piston engines (Wankel), twice the nominal swept volume of a combustion chamber per piston.

         2.12. "Pollution control devices" means those components of a vehicle that control and/or limit exhaust and evaporative emissions.

         2.13. "OBD" means an on-board diagnostic system for emission control, which has the capability of identifying the likely area of malfunction by means of fault codes stored in computer memory.

         2.14. "In-service test" means the test and evaluation of conformity conducted in accordance with paragraph 8.2.1. of this Regulation.

         2.15. "Properly maintained and used" means, for the purpose of a test vehicle, that such a vehicle satisfies the criteria for acceptance of a selected vehicle laid down in paragraph 2. of Appendix 3 to this Regulation.

         2.16. "Defeat device" means any element of design which senses temperature, vehicle speed, engine rotational speed, transmission gear, manifold vacuum or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control system, that reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal vehicle operation and use. Such an element of design may not be considered a defeat device if:

         2.16.1. the need for the device is justified in terms of protecting the engine against damage or accident and for safe operation of the vehicle, or

         2.16.2. the device does not function beyond the requirements of engine starting, or

         2.16.3. conditions are substantially included in the Type I or Type VI test procedures.

         2.17. "Family of vehicles" means a group of vehicle types identified by a parent vehicle for the purpose of Annex 12.

         2.18. "Fuel requirement by the engine" means the type of fuel normally used by the engine:

         – petrol,
         – LPG (liquefied petroleum gas),
         – NG (natural gas),
         – either petrol or LPG,
         – either petrol or NG,
         – diesel fuel.

         2.19. "Approval of a vehicle" means the approval of a vehicle type with regard to the limitation of the following conditions: 1[/

         2.19.1. limitation of exhaust emissions by the vehicle, evaporative emissions, crankcase emissions, durability of pollution control devices, cold start pollutant emissions and on-board diagnostics of vehicles fuelled with
