Abstract
Abstract An aqueous solution consisting mainly of an essential oil ingredient and water is obtained by immersing chips of at least one kind of herb in hot water of 70-90 °C for about 30 minutes. This solution is added, either as it is or concentrated, to a lower alkanol. The resulting mixture is a fuel for internal combustion engines which is comparable to petrol, and far superior to pure alcohol in performance and in not causing corrosion. It can contain 30% of water. For example, a car fuelled with a mixture of methanol (78%), water (20.8%) and an extract (1.2%) achieved 3.41 km/l, whereas on pure methanol it achieved only 3.04 km/l.

33 words
An additive for alcohol fuel comprising an effective component consisting of an aqueous extract containing an essential oil ingredient and obtained from at least one kind of herb containing said essential oil ingredient.
Claim 2
Dependent Claim
33 words
An additive for alcohol fuel comprising an effective component consisting of an aqueous extract containing an essential oil ingredient and obtained from at least one kind of herb containing said essential oil ingredient.
Claim 3
Dependent Claim
40 words
An additive according to claim 1, in which: said at least one kind of herb is selected from the botanical families of Umbelliferae, Compositae, Araceae, Santalaceae, Lauraceae, Rutaceae, Magnoliaceae, Nymphaeaceae, Labiatae, Zingiberaceae, Piperaceae, Liliaceae, Polygalaceae, Cyperaceae, Valerianaceae, Pinaceae and Gramineae.
Claim 4
Dependent Claim
74 words
A method of manufacturing an additive according to claim 1 or claim 2, comprising the steps of: immersing chips of said at least one kind of herb in hot water to allow said ingredient to exude in the hot water to form an aqueous solution of extract of said essential oil ingredient containing said chips; and separating said chips from the solution to provide an initial batch of an aqueous solution of said extract.
