| Abstract: | A joint project of government and industry people who studied the possible effect upon air pollution in Los Angeles of variations in the composition of gasoline sold in Los Angeles is discussed. No experimental automotive test work was undertaken in this project. However, prototype fuel blends were made and analyzed in order to simulate the effects certain changes would have upon photochemical smog formation. It is apparent from the results of this study that the potential of reducing smog in Los ngeles by fuel modifications is quite small, even in the year of maximum effect. This potential decreases to a negligible level due to the effectiveness of mechanical control of evaporative losses required in California starting with the 1970 model cars. |
