Evaporative emission standards.
Evaporative emission standards. Evaporative emissions from gasoline-fueled, natural gas-fueled, liquefied petroleum gas-fueled, ethanol-fueled and methanol-fueled vehicles must not exceed the standards in this paragraph (e) at low altitude conditions. The evaporative emission standards specified in 86.1811-04(e)(1) continue to apply at high altitude conditions. The standards apply equally to certification and in-use vehicles.
(1) Diurnal-plus-hot soak evaporative hydrocarbon standards.
(i) Hydrocarbons for LDV/LLDTs, HLDTs and MDPVs that are gasoline-fueled, dedicated natural gas-fueled, dedicated liquefied petroleum gas-fueled, dedicated ethanol-fueled, dedicated methanol-fueled and multi-fueled vehicles when operating on gasoline must not exceed the diurnal plus hot soak standards shown in Table S09-1 for the full three diurnal test sequence and for the supplemental two diurnal test sequence. The standards apply equally to certification and in-use vehicles, except as otherwise specified in paragraph (t) of this section. Table S09-1 follows:
