On-Road Vehicle and Engine Emission Regulations
32.3 (1) If a company’s subfleet includes one or more motorcycles that conform to a family emission limit that is greater than the applicable HC+NOx emission standard set out in the section of the CFR that is referred to in paragraph 17(a) or subsection 17.1(2), the company shall calculate the average HC+NOx value for the subfleet using the following formula:
[Σ (A x B x C)] / [Σ (B x C)]
where
- A
- is the applicable family emission limit, expressed to the same number of decimal places as the emission standard it replaced;
- B
- is the useful life of the engine family expressed in years or kilometres; and
- C
- is the number of motorcycles in the engine family.
(2) If a company’s subfleet includes one or more motorcycles that conform to a family emission limit that is greater than the fuel tank permeation emission standard set out in the section of the CFR that is referred to in paragraph 17(a), the company shall calculate the average fuel tank permeation value for its subfleet in accordance with the following formula:
[Σ (A x B x C x 365.24)] / [Σ (B x C x 365.24)]
where
- A
- is the applicable family emission limit, expressed to the same number of decimal places as the emission standard it replaced;
- B
- is the useful life of the engine family expressed in years; and
- C
- is the number of motorcycles in the engine family multiplied by the average internal surface area of the motorcycles’ fuel tanks, where the average internal surface area is expressed in m2 to at least three decimal places.
(3) The average HC+NOx value and average fuel tank permeation value for a subfleet shall be expressed in g/km and g/m²/d, respectively, and be rounded to one decimal place.
(4) When calculating the average HC+NOx value for a subfleet of the 2006 model year, a company may include all of its motorcycles of that model year, including those whose main assembly was completed before November 2, 2006.
