Water containing car fuel

Abstract

Emulsions of mineral automobile fuel, such as gasoline and diesel oil, and containing at least 77 percent by weight of water, are described as a usable motor fuel. When vegetable oil is worked into the mixture, the automotive fuel can contain a percentage of water that can vary over a wide range. The advantages in using fuel mixtures are lower fuel consumption, lower CO2 emissions, affordable automobile fuel, and a lengthening of the period for which the increasingly scarce reserves of mineral oil will be available.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an emulsion of water, a car fuel, such as petrol, diesel oil or a type of vegetable oil and an emulsifier. Emulsions can be used as a new car fuel and may contain at least 77 percent water by weight.

2. Brief Summary of the Invention

Object of the invention is to provide a payable car fuel that pollutes less than the usual fuels, to be realised by mixing water, at least in an amount up to 77 percent of the mixture weight, a usual car fuel and an emulsifier.

DETAILED DESCRIPTION OF THE INVENTION

This invention concerns an emulsified mixture of water with a motor fuel such as gasoline or diesel, and also concerns an emulsified mixture of vegetable oil. Emulsions can be used as motor fuels. The addition of water to gasoline is known in the United States where the fluid known as “dry-gas” is added to the gasoline to mix the water present in the tank with the gasoline to form a useable fuel. This concerns only small quantities of water.

The Austrian patent in the name of Gerhard Auer Int. WO 95/25154, predominately describes the creation of alcohol-water and gasoline-diesel-water emulsions containing less than 70% water by volume.

Furthermore, the American patent U.S. 2004/0121202 A1 gives the compositions of emulsions for improving fuel cell functioning.

The American patent U.S. 2004/0005622 A1 describes an emulsion that improves the combustion of carbon particles. It has been shown experimentally that mixtures containing by weight only 20 percent conventional mineral automobile fuel and 80 percent water can be used as automobile fuels.

Characteristic of the emulsions according to this invention is also that the quantity of fuel can be as low as 23 percent of the total weight of water and fuel, which means that the water forms more than 77 percent.

When vegetable oil is mixed with mineral fuel water and emulsifier, the percentage can vary over a wide range.

An example of a successful automotive fuel combination is an emulsion consisting of 10.7 percent gasoline, 19.3 percent vegetable oil and 70 percent water. Mixtures with more vegetable oil are also suitable for using as a motor fuel. Assuming that gasoline, octane, has a carbon content of 82%, this implies that the amount of CO2 emitted by the mixture is only 324 grams per kilogram of emulsion. This is a 90% reduction of emissions compared to the use of gasoline alone.

Emulsions that separate can be reconverted to homogeneous fuel by stirring or shaking.

Assuming a mixture of 80% water and 20% gasoline, leads to the estimate that the engine cylinder pressure can rise to more than 80 kg/cm². This is higher than the pressure occurring in normal gasoline engines. However, the ignition temperature is lower than in gasoline engines.

The advantages in using fuel mixtures are lower fuel consumption, lower CO2 emissions, affordable automobile fuel, and longer use of the increasingly scarce oil reserves.

Claims

1. Emulsions of water and fuel, such as gasoline, diesel oil, and oil, can be used as fuels in motors, with the characteristic that the water content is more than 77 percent of the total weight of the emulsion.

2. An emulsified mixture of water, a mineral automotive fuel and a vegetable oil can be used as an automotive fuel.
