§ 86.145-82 Calculations; particulate emissions.
(a) The final reported test results for the mass particulate (Mp) in grams/mile shall be computed as follows.
where:
(1) Mp1 = Mass of particulate determined from the “transient” phase of the cold start test, in grams per test phase. (See § 86.110-82(c)(1) for determination.)
(2) Mp2 = Mass of particulate determined from the “stabilized” phase of the cold start test, in grams per test phase. (See § 86.110-82(c)(1) for determination.)
(3) Mp3 = Mass of particulate determined from the “transient” phase of the hot start test, in grams per test phase. (See § 86.110-82(c)(1) for determination).
(4) Dct = The measured driving distance from the “transient” phase of the cold start test, in miles.
