Lead susceptibility charts

A similar relationship for the clear base of leaded regular-grade gasolines was developed from more than 200 commercial gasolines obtained from service stations. Knowing the lead content of each fuel and using our updated lead susceptibility charts (2), the clear RON can be estimated. Here again, the data result in a wide band. The best-fit line has been determined, and its equation is ... 

To show the relationship between percent aromatics and lead content, we have calculated the curve in Figure 2 using the leaded regular-fuel curve in Figure 1 and a lead susceptibility chart. 

By the use of a lead-susceptibility chart (Fig. 3-4) it is possible to assemble the gasoline stocks in various proportions to produce Regular and Premium Grades of gasoline. Some blending proportions result in lead consumptions that are less than half the amounts required by other blending proportions. ...
