Abstract
Alcohol based unleaded automotive racing fuels, using blends of four basic chemical components, including ethanol, methanol, toluene, and isopentane and/or cyclopentane. Mixtures provide increased power, and better charge cooling than conventional racing gasolines, whether leaded or unleaded. The claimed racing fuel blends do not include gasoline, isooctane, or alkylate fractions common to alcohol-gasoline mixtures such as E85 alcohol based fuels. The novel fuel blends claimed can be manufactured from commonly available pure chemical components, and make possible distributed manufacture of automotive racing fuels.
Claims9
A method of use of an unleaded automotive racing fuel blend in a spark ignited internal combustion piston engine:
- (a) providing an unleaded automotive racing fuel blend, wherein the racing fuel blend consists essentially of (1) methanol;
- (2) ethanol;
- (3) toluene;
- (4) isopentane or cyclopentane, or mixtures thereof;
- (5) optionally, one or more additives selected from the group consisting of anti-oxidants, anti-static additives, corrosion inhibitors, denaturants, co-solvents, lubricants, and mixtures thereof;
- (6) with a proviso that the fuel blend contains less than one percent (1%) of hydrocarbon constituents other than those set out herein;
- (b) combusting the unleaded automotive racing fuel blend in the spark ignited internal combustion piston engine;
- and
- (c) wherein the method of use of the unleaded automotive racing fuel blend provides one or more of:
- (1) reduced ten to ninety percent (10%-90%) burn duration, by crank degrees;
- (2) performance predictability based on a selected fuel blend;
- (3) reduced fuel testing costs;
- (4) reduced fuel testing turnaround time;
- (5) distributed fuel blending capability;
- and
- (6) reduced fuel blend manufacturing cost.
A method for operating spark ignited internal combustion piston engines in racing competition, the method comprising:
- (a) providing an unleaded automotive racing fuel blend, the unleaded automotive racing fuel blend consisting essentially of:
- (1) methanol at thirty five percent (35%), plus or minus five percent (5%) by volume;
- (2) ethanol at thirty five percent (35%), plus or minus five percent (5%) by volume;
- (3) toluene at from thirty five percent (35%) to fifteen percent (15%) by volume;
- (4) isopentane or cyclopentane, or mixtures thereof, at from ten percent (10%) to three percent (3%) by volume;
- (5) optionally, one or more additives selected from the group consisting of anti-oxidants, anti-static additives, corrosion inhibitors, denaturants, co-solvents, lubricants, and mixtures thereof;
- (6) said unleaded automotive racing fuel blend characterized in that the unleaded automotive racing fuel blend is selected and optimized for use in an automotive engine configured for supply of air and fuel to the automotive engine at an air-fuel ratio in a range of from 8:1 to 10:1;
- and
- (b) combusting said unleaded automotive racing fuel blend in an internal combustion spark ignition engine, to provide motive force for a race car.
