The TEL content of the dilute product is reduced to 49 mass percent, so that the amountof antiknock additive must

31、be adjusted to achieve the necessary lead level. The dilute product still delivers two bromine atoms peratom of lead.6.2.2 DyesThe maximum concentration limits in each grade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in the finished gasoline shall be essenti
