In addition to the on-road vehicles, a variety of agricultural and landscaping vehicles and equipment will receive the test fuel. Other tests of California RFG have already begun. Moreover, some VOCs can cause cancer. Gasoline and solvent-containing products are major sources of VOCs. Lower RVP in gasoline means less evaporation and less air pollution.
Aromatic hydrocarbons help determine the rate at which gasoline burns.
By limiting aromatics in gasoline, emissions of VOCs, nitrogen oxides, and toxics are significantly reduced. Distillation temperatures are the temperatures at which a given amount of gasoline will evaporate. The limits required for California RFG reduce emissions of VOCs in engine exhaust.
