This Regulation also establishes the detailed requirements with regard to type-approval procedures and conformity of production. Definitions Article 2 For the purposes of this Regulation, the following definitions shall apply: ‘engine’ means an energy converter, other than a gas turbine, designed to transform chemical energy (input) into mechanical energy (output) with an internal combustion process; it includes, where they have been installed, the emission control system and the communication interface (hardware and messages) between the engine's electronic control unit(s) and any other powertrain or vehicle control unit necessary to comply with Chapters II and III of Regulation (EU) 2016/1628; ‘engine type’ means a group of engines which do not differ in essential engine characteristics; ‘engine family’ means a manufacturer's grouping of engine types which, through their design, have similar exhaust emission characteristics, and respect the applicable emission limit values; ‘parent engine’ means an engine type selected from an engine family in such a way that its emissions characteristics are representative of that engine family; ‘replacement engine’ means an engine that meets both of the following criteria: it is exclusively used to replace an engine already placed on the market and installed in an agricultural and forestry vehicle; it complies with an emission stage which is lower than that applicable on the date of the engine's replacement; ‘net power’ means the engine power in kW obtained on a test bench at the end of the crankshaft, or its equivalent, measured in accordance with the method of measuring the power of engines specified in UNECE Regulation No 120 using a reference fuel or fuel combination laid down in Article 25(2) of Regulation (EU) 2016/1628; ‘transition engine’ means an engine that has an engine production date that is prior to the date laid down in Annex III to Regulation (EU) 2016/1628 in respect of the placing on the market of Stage V engines and that meets at least one of the following conditions: it complies with the latest applicable emission limits laid down in the relevant legislation applicable on 20 July 2018; it falls within a power range, or is used or intended to be used in an application that was not subject to pollutant emission related type-approval in accordance with Delegated Regulation (EU) 2015/96 on 20 July 2018; it is an engine in the power range 56-130 kW, meeting the Stage IIIB requirements and installed or intended to be installed in a tractor of categories T2, T4.1 or C2; ‘exhaust after-treatment system’ means a catalyst, particulate filter, deNOx system, combined deNOx particulate filter or any other emission-reducing device, with the exception of exhaust gas recirculation and turbochargers, that is part of the emission control system but is installed downstream of the engine exhaust ports; ‘external noise-abatement device’ means a component, system or separate technical unit which is part of the exhaust and the silencing system, including the exhaust system, the air intake system, the silencer or any systems, components, and separate technical units with a relevance to the permissible external sound levels emitted by the agricultural or forestry vehicle, of a type fitted to the vehicle at the time of type-approval or extension of type-approval; ‘SI engine’ means an engine that works on the spark-ignition (‘SI’) principle; ‘track belt’ means a continuous flexible rubber like belt, reinforced internally to enable the tractive forces; ‘track chain’ means a continuous metallic chain which engages with the track driver and where each link is with a transversal metallic track shoe, the latter optionally padded with a rubber strip for road surface protection; ‘in-service engine’ means an engine that is operated in agricultural and forestry vehicle over its normal operating patterns, conditions and payloads, and is used to perform the emission monitoring tests as referred to in Article 19 of Regulation (EU) 2016/1628; ‘maximum net power’ means the highest value of the net power on the nominal full-load power curve for the engine type; ‘engine production date’ means the date, expressed as the month and year, on which the engine passes the final check, after it has left the production line, and is ready to be delivered or to be put into stock; ‘vehicle production date’ means the month and year in which an agricultural and forestry vehicle passes the final check after it has left the production line and which are indicated on the statutory marking of that vehicle; ‘end-user’ means any natural or legal person, other than the manufacturer, vehicle manufacturer, importer or distributor, that is responsible for operating the engine installed in agricultural and forestry vehicles; ‘exhaust gas recirculation’ or ‘EGR’ means a technical device that is part of the emission control system and reduces emissions by routing exhaust gases that have been expelled from the combustion chamber(s) back into the engine to be mixed with incoming air before or during combustion, except for the use of valve timing to increase the amount of residual exhaust gas in the combustion chamber(s) that is mixed with incoming air before or during combustion; ‘tampering’ means inactivation, adjustment or modification of the emission control system, including any software or other logical control elements of such a system, that has the effect, whether intended or not, of worsening the emissions performance of the engine; ‘pollution control device’ means a component, system or separate technical unit which is part of the exhaust after-treatment system; ‘initial entry into service’ means: where the registration of agricultural or forestry vehicles is compulsory, the first registration in a Member State; where the registration of agricultural or forestry vehicles is compulsory only for road circulation or is not compulsory in a Member State, the placing on the market. Regulation No 120 of the Economic Commission for Europe of the United Nations (UNECE) — Uniform provisions concerning the approval of internal combustion engines to be installed in agricultural and forestry tractors and in non-road mobile machinery, with regard to the measurement of the net power, net torque and specific fuel consumption [2015/1000] (OJ L 166, 30.6.2015, p. 170).
