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--gasolines, diesel fuels, and alternative fuels--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 report 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.

Fuels and Lubricants TC 7 Fuels Committee
The Fuels Technical Committee 7 is responsible for the development of SAE Standards, Recommended Practices, Information Reports and related information pertinent to the technical aspects of fuels for internal combustion engines used in ground vehicles. The Truck and Bus J1616 Task Force has been formed under the committee's direction. Participants in the SAE Fuels Technical Committee include OEMs, suppliers, consulting firms, government and other interested parties.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
