The properties of gasoline and effect of this properties on calculation of air-fuel ratio

The statistical analysis of relations of properties of common fuels, the main component of gasoline and gasoline sold on market was carried out. It is obtained that the equations of the density and low heating value, the density and hydrogen carbon ratio H/C, the density and stoichiometric air-fuel ratio. According to these equations, we can improve the precision of thermal analysis, measurement and control of air-fuel ratio in gasoline engines.
