Heating Value of Fuels
2017-09-07
CURRENT
J1498_201709
The heating value or heat of combustion is a measure of the energy available from the fuel. The fraction or percentage of the heat of combustion that is converted to useful work is a measure of the thermal efficiency of an engine. Thus, a knowledge of the heat of combustion of the fuel is basic to the engineering of automotive engines. This SAE Information Report provides information on the standardized procedures for determining the heat of combustion of fuels that may be used for automotive engines. The changes to SAE J1498 include: SAE Publications - Added SAE Paper 2010-01-1517 Other Publications and Sections 5, 9, and 10 - Updated ASTM alphanumeric designations and titles. Section 10 - Added discussion of a method to calculate net heating value for gasoline-ethanol blends using ASTM D3338.

Stoichiometric Air-Fuel Ratios of Automotive Fuels
2015-03-17
CURRENT
J1829_201503
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. This 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 or 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.

Recommended Practice for Compressed Natural Gas Vehicle Fuel
1994-02-01
HISTORICAL
J1616_199402
Compressed Natural Gas (CNG) is a practical automotive fuel, with advantages and disadvantages when compared to gasoline. It has a good octane quality, is clean burning, easy to meter, and generally produces lower vehicle exhaust emissions. CNG is used to fuel internal combustion engines. Natural gas is normally compressed form 20 690 to 24 820 kPa (3000 to 3600 psig) to increase its energy density thereby reducing its on-board vehicle storage volume for a given range and payload. The properties of natural gas are influenced by (1) the processing of natural gas by the production and transmission companies and (2) the regional gas supply, storage, and demand balancing done by distribution companies often in concert with pipeline companies to maintain uninterrupted service throughout the year, e.g., peakshaving with propane-air (see U.S. Bureau of Mines Publication 503).
