Calculations; particulate emissions.

§ 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.

Mp = 0.43(Mp1 + Mp2)/(Dct + Ds) + 0.57(Mp3 + Mp2)/(Dht = Ds)

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.
