[Code of Federal Regulations] [Title 40, Volume 17] [Revised as of July 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR86.229-94] [Page 582-583] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 86_CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES AND ENGINES--Table of Contents Subpart C_Emission Regulations for 1994 and Later Model Year Gasoline- Sec. 86.229-94 Road load force, test weight, and inertia weight class determination. (a) Flywheels, electrical forces, or other means of simulating test weight as shown in the table in this paragraph shall be used. If the equivalent test weight specified is not available on the dynamometer being used, the next higher equivalent test weight (not to exceed 250 pounds) available shall be used. Light-duty vehicles over 5750 lbs. loaded vehicle weight shall be tested at a 5,500 lb. equivalent test weight. ------------------------------------------------------------------------ Equivalent Inertia test weight Loaded vehicle weight (pounds) weight class (pounds) (pounds) ------------------------------------------------------------------------ Up-1,062........................................ 1,000 1,000 1,063-1,187..................................... 1,125 1,000 1,188-1,312..................................... 1,250 1,250 1,313-1,437..................................... 1,375 1,250 1,438-1,562..................................... 1,500 1,500 1,563-1,687..................................... 1,625 1,500 1,688-1,812..................................... 1,750 1,750 1,813-1,937..................................... 1,875 1,750 1,938-2,062..................................... 2,000 2,000 2,063-2,187..................................... 2,125 2,000 2,188-2,312..................................... 2,250 2,250 2,313-2,437..................................... 2,375 2,250 2,438-2,562..................................... 2,500 2,500 2,563-2,687..................................... 2,625 2,500 2,688-2,812..................................... 2,750 2,750 2,813-2,937..................................... 2,875 2,750 2,938-3,062..................................... 3,000 3,000 3,063-3,187..................................... 3,125 3,000 3,188-3,312..................................... 3,250 3,000 3,313-3,437..................................... 3,375 3,500 3,438-3,562..................................... 3,500 3,500 3,563-3,687..................................... 3,625 3,500 3,688-3,812..................................... 3,750 3,500 3,813-3,937..................................... 3,875 4,000 3,938-4,125..................................... 4,000 4,000 4,126-4,375..................................... 4,250 4,000 4,376-4,625..................................... 4,500 4,500 4,626-4,875..................................... 4,750 4,500 4,876-5,125..................................... 5,000 5,000 5,126-5,375..................................... 5,250 5,000 5,376-5,750..................................... 5,500 5,500 5,751-6,250..................................... 6,000 6,000 6,251-6,750..................................... 6,500 6,500 6,751-7,250..................................... 7,000 7,000 7,251-7,750..................................... 7,500 7,500 7,751-8,250..................................... 8,000 8,000 8,251-8,750..................................... 8,500 8,500 8,751-9,250..................................... 9,000 9,000 9,251-9,750..................................... 9,500 9,500 9,751-10,000.................................... 10,000 10,000 ------------------------------------------------------------------------ (b) A dynamometer which meets the specifications of Sec. 86.208- 94(a) shall be adjusted to simulate the operation of a vehicle on the road at 20 [deg]F (-7 [deg]C). [[Page 583]] Such adjustment may be based on a determination of the road load force profile at 20 [deg]F (-7 [deg]C). Alternatively, the adjustment may be based on a 10 percent decrease in the target coastdown time that is used for FTP testing.
