Abstract

Abstract A diesel engine fuel consisting essentially of about 25-75% of a butyl alcohol and about 75-25% of a vegetable oil which is normally liquid under operating conditions, both percentages being by volume, constitutes a clean burning, smooth running fuel composition for diesel engines that delivers engine speed and power substantially equal to that of No. 2 diesel oil but burns with less perceptible exhaust smoke and odor, starts easily without external ignition aids at temperatures at least as low as about 14° F., and is compatible in all proportions with No. 2 diesel oil.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 59 words
A fuel composition for a diesel internal combustion engine which consists essentially of a homogeneous mixture of about 25-75% of a vegetable seed oil which is normally liquid at the ambient operating temperature range of said engine and free of matter which is solid within said range, and about 75-25% of a butyl alcohol, said percentages being by volume.
Claim 2
Dependent Claim 59 words
A fuel composition for a diesel internal combustion engine which consists essentially of a homogeneous mixture of about 25-75% of a vegetable seed oil which is normally liquid at the ambient operating temperature range of said engine and free of matter which is solid within said range, and about 75-25% of a butyl alcohol, said percentages being by volume.
Claim 3
Dependent Claim 57 words
In a method of operating a diesel internal combustion engine, the improvement of supplying to said engine as fuel a homogeneous mixture consisting essentially of about 25-75% of a vegetable oil which is normally liquid at the ambient temperature in which said engine is operated and about 75-25% of a butyl alcohol, said percentages being by volume.
Claim 4
Dependent Claim 57 words
In a method of operating a diesel internal combustion engine, the improvement of supplying to said engine as fuel a homogeneous mixture consisting essentially of about 25-75% of a vegetable oil which is normally liquid at the ambient temperature in which said engine is operated and about 75-25% of a butyl alcohol, said percentages being by volume.
Claim 5
Dependent Claim 24 words
The composition of claim 1 wherein the vegetable oil is corn oil, sunflower seed oil, peanut oil, soybean oil, linseed oil or cottonseed oil.
Claim 6
Dependent Claim 24 words
The method of claim 2 wherein the vegetable oil is corn oil, sunflower seed oil, peanut oil, soybean oil, linseed oil or cottonseed oil.
Claim 7
Dependent Claim 19 words
The composition of claim 1 wherein the mixture contains about 50% of said oil and 50% of said alcohol.
Claim 8
Dependent Claim 19 words
The method of claim 2 wherein the mixture contains about 50% of said oil and 50% of said alcohol.
