Original text. Later amendments are not shown.

For the purposes of this Annex the following definitions shall apply:

  1. 2.1.

    ‘GER (Gas Energy Ratio)’ has the meaning defined in Article 3(20) of Regulation (EU) 2016/1628 based on the lower heating value;

  2. 2.2.

    ‘GERcycle’ means the average GER when operating the engine on the applicable engine test cycle;

  3. 2.3.

    ‘Dual-fuel Type 1A engine’ means either:

    1. (a)

      a dual-fuel engine of a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the hot-start NRTC test-cycle with an average gas energy ratio that is not lower than 90 % (GERNRTC, hot ≥ 0,9) and that does not idle using exclusively liquid fuel, and that has no liquid-fuel mode, or;

    2. (b)

      a dual-fuel engine of any (sub-) category other than a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the NRSC with an average gas energy ratio that is not lower than 90 % (GERNRSC ≥ 0,9) and that does not idle using exclusively liquid fuel, and that has no liquid-fuel mode;

  4. 2.4.

    ‘Dual-Fuel Type 1B engine’ means either:

    1. (a)

      a dual-fuel engine of a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the hot-start NRTC test-cycle with an average gas energy ratio that is not lower than 90 % (GERNRTC, hot ≥ 0,9) and that does not idle using exclusively liquid fuel in dual-fuel mode, and that has a liquid-fuel mode, or;

    2. (b)

      a dual-fuel engine of any (sub-) category other than a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the NRSC with an average gas energy ratio that is not lower than 90 % (GERNRSC ≥ 0,9) and that does not idle using exclusively liquid fuel in dual-fuel mode, and that has a liquid-fuel mode;

  5. 2.5.

    ‘Dual-Fuel Type 2A engine’ means either:

    1. (a)

      a dual-fuel engine of a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the hot-start NRTC test-cycle with an average gas energy ratio between 10 % and 90 % (0,1 < GERNRTC, hot < 0,9) and that has no liquid-fuel mode or that operates over the hot-start NRTC test-cycle with an average gas energy ratio that is not lower than 90 % (GERNRTC, hot ≥ 0,9), but that idles using exclusively liquid fuel, and that has no liquid-fuel mode, or;

    2. (b)

      a dual-fuel engine of any (sub-) category other than a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the NRSC with an average gas energy ratio between 10 % and 90 % (0,1 < GERNRSC < 0,9), and that has no liquid-fuel mode or that operates over the NRSC with an average gas energy ratio that is not lower than 90 % (GERNRSC ≥ 0,9), but that idles using exclusively liquid fuel, and that has no liquid-fuel mode;

  6. 2.6.

    ‘Dual-Fuel Type 2B engine’ means either:

    1. (a)

      a dual-fuel engine of a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the hot-start NRTC test-cycle with an average gas energy ratio between 10 % and 90 % (0,1 < GERNRTC, hot < 0,9) and that has a liquid-fuel mode or that operates over the hot-start NRTC test-cycle with an average gas energy ratio that is not lower than 90 % (GERNRTC, hot ≥ 0,9), and that has a liquid-fuel mode but that can idle using exclusively liquid fuel in dual-fuel mode, or;

    2. (b)

      a dual-fuel engine of any (sub-) category other than a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the NRSC with an average gas energy ratio between 10 % and 90 % (0,1 < GERNRSC < 0,9), and that has no liquid-fuel mode or that operates over the NRSC with an average gas energy ratio that is not lower than 90 % (GERNRSC ≥ 0,9), and that has a liquid-fuel mode but that can idle using exclusively liquid fuel in dual-fuel mode;

  7. 2.7.

    ‘Dual-Fuel Type 3B engine’ means either:

    1. (a)

      a dual-fuel engine of a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the hot-start NRTC test-cycle with an average gas energy ratio that does not exceed 10 % (GERNRTC, hot ≤ 0,1) and that has a liquid-fuel mode, or:

    2. (b)

      a dual-fuel engine of any (sub-) category other than a sub-category of NRE 19 ≤ kW ≤ 560, that operates over the NRSC with an average gas energy ratio that does not exceed 10 % (GERNRSC ≤ 0,1) and that has a liquid-fuel mode;
