Definitions
- This invention relates to antiknock compounds.
- Many attempts have been made to use iron carbonyl as an antiknock agent in high compression engines, chiefly because it can be manufactured at a lower cost than the lead alkyls.- Some of these attempts have included the use of lead alkyls in very small proportional quantities. These attempts have not had any appreciable success and the reason for this has not been clear. So far as I am aware these attempts have been based on a primary consideration of the use of iron carbonyl, and other factors were wholly secondary to this.
- the object of the present invention is to provide useful antiknock mixtures of tetraalkyl lead and iron pentacarbonyl.
- the single figure of the drawing is a chart illustrating the antiknock values of different mixtures of tetraalkyl lead and iron pentacarbonyl when added to a widely used commercial base fuel.
- This fuel was the base for Standard Oil bonyl is indicated as grams of iron per gallon.
- the corresponding volumes 0! tetraethyl lead and iron pentacarbonyl are shown in parentheses on the horizontal and vertical scales respectively.
- Each line, A to M inclusive, indicates mixtures having a constant antiknock value. Mixtures indicated by line A have the lowest antiknock value and lines lying to the right of A indicate mixtures of progressively higher antiknock value.
- Each ofthese lines may be used in the following manner, taking line H as an example. This line starts from the horizontal axis at 1.32 grams of lead (1.25 c. c. of, tetraethyl lead) and 0.0 grams ofiron per gallon of fuel, indicating that the fuel contains 1.32 grams of lead and no iron pentacarbonyl. If 0.21 gram of iron (0.5 c.
- the horizontal axis OX indicates the quantity of lead alkyl in the mixture per gallon of fuel and the vertical axis OY'indicates the quantity of iron pentacarbonyl in the mixture per gallon of fuel. Inasmuch as the quantity of lead in a given volume of the dif-' ferent lead alkyls is not constant, the quantity of lead alkyl is indicated as grams of lead per gallon. Likewise the quantity of iron pentacargrams of lead per gallon.
- iron pentacarbonyl n grams of lead per gallon has the same effect as the 0.0 grams of iron and 1.32 Between these two points on the curve the compounds are so mutually toxic that the addition of'the iron pentacarbonyl results in a'loss of antiknock value and therefore the addition of iron pentacarbonyl is ent in the mixture gives a useful result but at no point on the curve is the value of the mixture equal to the sum of the values of the two constituents. The value of a mixture cannot be predicated upon a knowledge of the values of each of the compounds in the mixtures.
- the mixture chosen depends on the cost of the components of the mixture, the increment of antiknock value desired from the mixture, the nature of the base fuel, the type of engine,-the conditions of engine operation and the increased rate of engine wear attributable to the antiknock mixture.
- iron pentacarbonyl also suggests this inasmuch as the antiknock mixture will be more evenly distributed during periods of poor fuel distribution.
- mixtures having a relatively high iron pentacarbonyl content because I have found that products of combustion of iron pentacarbonyl which remain in the combustion chamber have less tendency to cause preignition than those of tetraethyl lead.
- a relatively high iron pentacarbonyl content is desirable because of the increased effectiveness of iron pentacarbonyl relative to tetraalkyl lead compounds under these conditions.
- I employ mixtures having an iron pentacarbonyl content of not more than 4.0 c. 0. per gallon, equivalent to 1.68 grams of iron, as indicated by line NR.
- the curves for mixtures containing other lead alkyls with iron pentacarbonylv may vary from those for mixtures containing iron pentacarbonyl and tetraethyl lead but if they vary the differences are not material as to a choice of the mixture to be used.
- Tetraethyl lead is used more widely than any other lead compound as an antiknock and for this reason its use with iron pentaoarbonyl has been described above.
- the more useful range of lead alkyls for admixture with iron pentacarbonyl appears to extend from lead dimethyl diethyl to the heavier alkyls such as lead tetra-n-butyl.
- An antiknock mixture consisting of by volume substantially three partsiron pentacarbonyl and one part tetraethyl lead.
