Heavy-duty Engines

N2O and CH4 Emissions

Marginal note:Standards

  •  (1) Subject to paragraph 25(d), every heavy-duty engine that is a compression-ignition engine of the 2014 model year or a subsequent model year and every heavy-duty engine that is a spark-ignition engine of the 2016 model year or a subsequent model year must, for the duration of their useful life, have N2O and CH4 emission values that do not exceed 0.10 g/BHP-hr.

  • Marginal note:Values

    (2) The N2O and CH4 emission values for the engines referred to in subsection (1) correspond to the emission values of the tested engine configuration referred to in section 235(a) of Title 40, chapter I, subchapter U, part 1036, subpart C, of the CFR, for the engine family, measured in accordance with the transient duty cycle, taking into account sections 108(d) to (f) and 150(g) of subpart B, sections 235(b) and 241(c) and (d) of subpart C and subparts E and F of part 1036, Title 40, chapter I, subchapter U, of the CFR.

  • Marginal note:Engine configuration

    (3) For the purposes of subsection (2), the tested engine configuration for the model year in question is determined using the engine sales in Canada if none of the engines of the engine family are sold in the United States.

  • Marginal note:Fleet calculation

    (4) A company that manufactures or imports engines referred to in subsection (1) whose N2O emission value or CH4 emission value exceeds the emission standard set out in that subsection must group those engines of a given model year into fleets in accordance with section 18 and must calculate the N2O or CH4 emission deficit, as the case may be, for each of those fleets, expressed in megagrams of CO2, using the formula

    ((A – B) × C × D × E × F) ÷ (1 000 000)

    where

    A
    is 0.10 g/BHP-hr;
    B
    is the N2O or CH4 family emission limit for the fleet, as the case may be, expressed in g/BHP-hr;
    C
    is the number of engines in the fleet;
    D
    is the transient cycle conversion factor calculated in accordance with the applicable variable “CF” in section 705(b) of Title 40, chapter I, subchapter U, part 1036, subpart H, of the CFR, except that a reference to “production volumes” in that section must be read as a reference to “number of engines of that engine family that a company imports or manufactures in Canada for the purpose of sale in Canada to the first retail purchaser”;
    E
    is the engine’s useful life, expressed in miles; and
    F
    is the global warming potential and is equal to the following number of CO2 emission credits, expressed in megagrams of CO2, needed to offset a deficit of N2O or CH4:
    • (a) for each megagram of N2O, 298; and

    • (b) for each megagram of CH4,

      • (i) for the 2020 model year and earlier model years, 25, and

      • (ii) for the 2021 model year and subsequent model years, 34.

  • Marginal note:Separate calculation

    (4.1) For the purposes of subsection (4), if both the N2O emission value and the CH4 emission value exceed 0.10 g/BHP-hr, the N2O and CH4 emission deficits must be calculated separately.

  • Marginal note:Family emission limit

    (5) For the purposes of subsection (4), every heavy-duty engine within a fleet must conform to the N2O or CH4 family emission limit for the fleet.

  • Marginal note:Offsetting fleet emission deficit

    (6) The deficit calculated under subsection (4) must be offset by using the CO2 emission credits obtained in accordance with sections 34 to 47 for the averaging set in which the fleet is included.

  • Marginal note:No credits

    (7) For greater certainty, and subject to subsection (8), the company must not obtain CO2 emission credits with respect to N2O and CH4 emissions for the purpose of participation in the CO2 emission credit system set out in sections 34 to 47.

  • Marginal note:Credits for low N2O emissions

    (8) If a company’s heavy-duty engines from a fleet of the 2014, 2015 or 2016 model year conform to an N2O family emission limit that is less than 0.04 g/BHP-hr, the company may obtain CO2 emission credits for the purpose of participation in the CO2 emission credit system set out in sections 34 to 47. The credits must be calculated using the following formula, for each fleet, and be expressed in megagrams of CO2:

    ((A – B) × C × D × E × F) ÷ (1 000 000)

    where

    A
    is 0.04 g/BHP-hr;
    B
    is the N2O family emission limit for the fleet, expressed in g/BHP-hr;
    C
    is the number of engines in the fleet;
    D
    is the transient cycle conversion factor calculated in accordance with the applicable variable “CF” in section 705(b) of Title 40, chapter I, subchapter U, part 1036, subpart H, of the CFR, except that a reference to “production volumes” in that section must be read as a reference to “number of engines of that engine family that a company imports or manufactures in Canada for the purpose of sale in Canada to the first retail purchaser”;
    E
    is the engine’s useful life, expressed in miles; and
    F
    is the global warming potential and is equal to 298 Mg of CO2.

CO2 Emissions

Marginal note:Standard

  •  (1) Subject to subsection (2), paragraph 25(d) and sections 31 and 33, every heavy-duty engine of a given model year must, for the duration of its useful life, have a CO2 emission value that does not exceed the following CO2 emission standard:

    • (a) in the case of a spark-ignition engine of the 2016 to 2020 model years, 627 g/BHP-hr;

    • (b) in the case of a spark-ignition engine of the 2021 model year or a subsequent model year other than a heavy heavy-duty engine, 627 g/BHP-hr;

    • (c) in the case of a compression-ignition engine of the 2014 to 2020 model years that is of a type referred to in column 1 of the table to this paragraph, the standard set out in column 2 or 3 for the model year in question; or
