ANNEX IX

Parameters for the definition of engine types and engine families, and their operation modes

1. Engine type

The technical features of an engine type shall be those defined in its information document drafted in accordance with the template set out in Annex I.

An engine type may be EU type-approved as a constant speed engine or as a variable speed engine, as defined in Articles 3(21) and 3(22) of Regulation (EU) 2016/1628.

1.1.1.1. In the case that, as allowed by Article 4(2) of Regulation (EU) 2016/1628, a variable-speed engine of a particular category is used in place of a constant-speed engine of the same category, the parent engine (for the purposes of EU type-approval) and all engine types within the engine family (for the purposes of conformity of production), shall be tested using the applicable variable speed NRSC and additionally, where required by Article 24(9) or Article 24(10) of Regulation (EU) 2016/1628, the applicable transient cycle. As set out in Article 24(5) of Regulation (EU) 2016/1628, except in the case of engines of category IWP, a variable speed engine of a particular category used in a constant speed operation of the same category need not be additionally tested using the applicable constant speed NRSC.

1.1.2.1. The constant speed governor function shall be engaged during constant speed operation. The governors of constant speed engines may not be required to continuously maintain speed exactly constant. The speed may decrease below the speed at zero load, so that the minimum speed occurs near the engine's point of maximum power. This is typically in the region of 0,1 to 10 per cent.

1.1.2.2. In the case that the engine type is equipped with an idle speed for start-up and shut-down as permitted by Article 3(21) of Regulation (EU) 2016/1628 the engine shall be installed in a manner to ensure that the constant speed governor function is engaged prior to increasing the load-demand to the engine from the no-load setting.

2. Engine family criteria

An engine family is characterised by design parameters. These shall be common to all engines within the engine family. The engine manufacturer may decide, which engines belong to an engine family, as long as the membership criteria listed in paragraph 2.4 are respected. The engine family shall be approved by the approval authority. The manufacturer shall provide to the approval authority the appropriate information relating to the emissions levels of the members of the engine family.

2.2.1. An engine family shall only comprise engine types within the same engine category as set out in Article 4 (1) of Regulation (EU) 2016/1628.

2.2.2. The engine family shall comprise only engine types of the same speed operation as set out in Annex I to Regulation (EU) 2016/1628.

In some cases there may be interaction between parameters, which may cause emissions to change. This shall be taken into consideration to ensure that only engines with similar exhaust emissions characteristics are included within the same engine family. These cases shall be identified by the manufacturer and notified to the approval authority. It shall then be taken into account as a criterion for creating a new engine family.

In case of devices or features, which are not listed in paragraph 2.4 and which have a strong influence on the level of emissions, this equipment shall be identified by the manufacturer using good engineering judgment, and shall be notified to the approval authority. It shall then be taken into account as a criterion for creating a new engine family.

In addition to the parameters listed in paragraph 2.4, the manufacturer may introduce additional criteria allowing the definition of families of more restricted size. These parameters are not necessarily parameters that have an influence on the level of emissions.

(a) 2-stroke cycle;

(b) 4-stroke cycle;

(c) Rotary engine;

(d) Others.

(a) Single

(b) V;

(c) In-line;

(d) Opposed;

(e) Radial;

(f) Others (F, W, etc.).

Engines with the same block may belong to the same engine family as long as their bore centre-to-centre dimensions are the same.

(a) Air;

(b) Water;

(c) Oil.

In order for engines with a swept volume per cylinder of ≥ 750 cm³ to be considered to belong to the same engine family, the spread of their swept volume per cylinder shall not exceed 15 per cent of the largest swept volume per cylinder within the engine family.

In order for engines with an individual cylinder swept volume of < 750 cm³ to be considered to belong to the same engine family, the spread of their swept volume per cylinder shall not exceed 30 per cent of the largest swept volume per cylinder within the engine family.

Notwithstanding points 2.4.4.1 and 2.4.4.2, engines with a swept volume per cylinder that exceeds the spread defined in paragraphs 2.4.4.1 and 2.4.4.2 may be considered to belong to the same engine family subject to the approval of the approval authority. The approval shall be based on technical elements (calculations, simulations, experimental results etc.) showing that exceeding the spread does not have a significant influence on the exhaust emissions.

(a) Naturally aspirated;

(b) Pressure charged;

(c) Pressure charged with charge cooler.

(a) Diesel (non-road gas-oil);

(b) Ethanol for dedicated compression ignition engines (ED95);

(c) Petrol (E10);

(d) Ethanol (E85).

(e) Natural gas/Biomethane: (1) Universal fuel — high calorific fuel (H-gas) and low calorific fuel (L-gas); (2) Restricted fuel — high calorific fuel (H-gas); (3) Restricted fuel — low calorific fuel (L-gas); (4) Fuel specific (LNG);

(f) Liquid Petroleum Gas (LPG);

(a) Liquid-fuel only;

(b) Gaseous-fuel only;

(c) Dual-fuel type 1A;

(d) Dual-fuel type 1B;

(e) Dual-fuel type 2A;

(f) Dual-fuel type 2B;

(g) Dual-fuel type 3B.

(a) Open chamber;

(b) Divided chamber;

(c) Other types.

(a) Spark ignition;

(b) Compression ignition.

(a) Configuration;

(b) Number of valves per cylinder.

(a) Pump, (high pressure) line and injector;

(b) In-line pump or distributor pump;

(c) Unit injector;

(d) Common rail;

(e) Carburettor;

(f) Port injector;

(g) Direct injector;

(h) Mixing unit;

(i) Other.

(a) Exhaust gas recirculation (EGR);

(b) Water injection;

(c) Air injection;

(d) Others.

The presence or absence of an ECU on the engine is regarded as a basic parameter of the engine family.

In the case of electronically controlled engines, the manufacturer shall present the technical elements explaining the grouping of these engines in the same engine family, i.e. the reasons why these engines can be expected to satisfy the same emissions requirements.

The electronic governing of speed does not need to be in a different engine family from those with mechanical governing. The need to separate electronic engines from mechanical engines should only apply to the fuel injection characteristics, such as timing, pressure, rate shape, etc.

The function and combination of the following devices are regarded as membership criteria for an engine family:

(a) Oxidation catalyst;

(b) DeNOx system with selective reduction of NOx (addition of reducing agent);

(c) Other DeNOx systems;

(d) Particulate after-treatment system with passive regeneration: (1) wall-flow, (2) non-wall-flow;

(e) Particulate after-treatment system with active regeneration: (1) wall-flow, (2) non-wall-flow;

(f) Other particulate after-treatment systems;

(g) Other devices.

When an engine has been certified without exhaust after-treatment system, whether as parent engine or as member of the engine family, then this engine, when equipped with an oxidation catalyst (not with particulate after-treatment system), may be included in the same engine family, if it does not require different fuel characteristics.

If it requires specific fuel characteristics (e.g. particulate after-treatment systems requiring special additives in the fuel to ensure the regeneration process), the decision to include it in the same engine family shall be based on technical elements provided by the manufacturer. These elements shall indicate that the expected emissions level of the equipped engine complies with the same limit value as the non-equipped engine.

When an engine has been certified with exhaust after-treatment system, whether as parent engine or as member of an engine family, whose parent engine is equipped with the same exhaust after-treatment system, then this engine, when equipped without exhaust after-treatment system, shall not be added to the same engine family.

All engine types within a dual-fuel engine family shall belong to the same type of dual-fuel engines defined in section 2 (for example type 1A, type 2B, etc.), and operate with the same types of fuel or when appropriate with fuels declared according to this Regulation as being of the same range(s).

In addition to belonging to the same dual fuel type, they shall have a maximum gas energy ratio on the applicable test cycle (GERcycle) within the range 70 to 100 per cent of that of the engine type with the highest GERcycle.

2.4.16. Intake air temperature for engines of category NRS < 19 kW:

2.4.17. In case of engine categories in Table V-3 or V-4 of Annex V to Regulation (EU) 2016/1628 that have alternative values for EDP, the EDP category declared by the manufacturer:

3. Choice of the parent engine

3.1.1. Once the engine family has been agreed by the approval authority, the parent engine of the engine family shall be selected using the primary criterion of the highest fuel delivery per stroke per cylinder at the declared maximum torque speed. In the event that two or more engines share this primary criterion, the parent engine shall be selected using the secondary criterion of highest fuel delivery per stroke at rated speed.

3.1.2. The approval authority may conclude that the worst-case emissions rate of the engine family can best be characterised by testing an alternative or an additional engine. In this case, the parties involved shall have the appropriate information to determine the engines within the engine family likely to have the highest emissions level.

3.1.3. If engines within the engine family incorporate other variable features which may be considered to affect exhaust emissions, these features shall also be identified and taken into account in the selection of the parent engine.

3.1.4. If engines within the engine family meet the same emissions values over different emissions durability periods, this shall be taken into account in the selection of the parent engine.

3.2.1. In order to select the parent engine in the case of any variable speed engine family of category IWP containing one or more engine types to be placed on the market for other inland waterway applications in accordance with paragraph 1.1.1.2, the requirements of paragraph 3.1.1 shall be applied based upon the E3 NRSC. The evaluation of the requirements of paragraphs 3.1.2, 3.1.3 and 3.1.4 shall consider all NRSC for which an engine type is being type-approved.

3.2.2. In order to select the parent engine in the case of any constant speed engine family containing one or more engine types with alternative constant speeds as set out in paragraph 1.1.2.3, the evaluation of the requirements of paragraph 3.1 shall be applied to each constant speed of each engine type.

3.2.3. In order to select the parent engine in the case of any constant speed engine family of category IWP containing one or more engine types to be placed on the market for constant speed IWA applications in accordance with paragraph 1.1.2.4, the requirements of paragraph 3.1.1 shall be applied based upon the E2 NRSC. The evaluation of the requirements of paragraphs 3.1.2, 3.1.3 and 3.1.4 shall consider all NRSC for which an engine type is being type-approved.
