Title:Stoichiometric Air-Fuel Ratios of Automotive Fuels
Issuing Committee:Fuels And Lubricants Tc 7 Fuels
Scope: The mass of air required to burn a unit mass of fuel with no excess of oxygen or fuel left over is known as the stoichiometric air-fuel ratio. The ratio varies appreciably over the wide range of fuels聴gasolines, diesel fuels, and alternative fuel聴-that might be considered for use in automotive engines. Although performance of engines operating on different fuels may be compared at the same air-fuel ratio of same fuel-air ratio, it is more appropriate to compare operation at the same equivalence ratio, for which a knowledge of stoichiometric air-fuel ratio is a prerequisite. This SAE Recommended Practice summarizes the computation of stoichiometric air-fuel ratios from a knowledge of a composition of air and the elemental composition of the fuel without a need for any information on the molecular weight of the fuel.【英文标准名称】:
