BACKGROUND OF THE INVENTION The internal combustion engine is used to convert the chemical energy of fuel into heat energy and then converts this heat energy into useful mechanical energy. This is achieved by combining the appropriate amounts of air and fuel and burning the mixture in an enclosed cylinder at a controlled rate.

An average mass of air to mass of fuel ratio of good combustion for Petrol engine is about 15 parts of air to 1 part of fuel by weight. Diesel engine operates on a much wider mass of air to mass of fuel ratio, since air intake is not regulated on most diesel engines. Ratio may range from about 20: 1 to about 100: 1. This fact, plus the high compression of the diesel engine, makes it a fuel efficient engine.

But the ratio of air and fuel becomes insufficient due to the poor quality of oxygen and the different grades of fuel entering into the engine. These are the main factors that affect energy loss of an internal combustion engine.

The efficiency of existing internal combustion engine illustrated in Figure 1, in converting the potential energy in fuel to mechanical energy is only about 33%. Of the available fuel energy in an engine, about one-third is lost, due to the following factors: The main factor is pyrolysis, which is caused by the mixing of undesirable gas compounds with hydrocarbon gas vapours vented out from the positive crankcase vent and the fuel tank vent connected to the air induction system, of an engine. The mixing of undesirable gas compound upsets the ratio of oxygen for combustion process.

The other factor is loss of hydrocarbon gas vapours vented out to the atmosphere from the fuel tank vent, and the positive crankcase vent. These factors contributes to the loss of energy and the imbalance of mass of air to mass of fuel ratio. The remaining one-third energy loss of hydrocarbon gas vapours is through the emission of unbumed hydrocarbon in the exhaust system. These energy losses results to poor combustion.

Accordingly, it is desirable to provide an apparatus to produce negatively charged pre- oxidized hydrocarbon gas vapours to combine with the air and fuel mixture in the combustion chamber to improve the mass of air to mass of fuel ratio of an internal combustion engine.

In addition, the ambient air consisting of nitrogen and oxygen (N+02), upon mixing with the negatively charged pre-oxidized hydrocarbon gas vapours (HC + OH-+0-2) combined with the vaporised hydrocarbon fuel (HC) in the combustion chambers, increasing oxygen content and additional pre-oxidized hydrocarbon to enhance combustion process by promoting greater expansion of the pistons during combustion process. After combustion, the emission of exhaust chemical formation have lower counts of hydrocarbons (<HC), carbon monoxide (<CO), lower oxides of nitrogen (<NOx), lower carbon particulate (<CP) with more compound gases of carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2) and extra oxygen (02).

Here is the equation that shows what happens after combustion in an engine with the negatively charged pre-oxidized hydrocarbon gas vapours from a combustion enhancer apparatus.

HC+N+02+(HC+OI+O -<HC+aCp+tp+aCP+Cpi+NOZ+Hr0++01 SUMMARY OF THE INVENTION The main objective is to provide a liquid mixture for disassociating the introduced hydrocarbon gas vapours, radical hydrogen gases and oxygen gases to produce methane, ethane hydrocarbon, hydroxides and oxygen gas vapours to form a negatively charged pre-oxidized hydrocarbon gas vapours in a combustion enhancer apparatus for internal combustion engine..

Particularly, but not limited, for improving the mass of air to mass of fuel ratio of an internal combustion engine.

A liquid mixture containing the lowest molecular weight alcohol; methanol, CH3 OH and ethanol, C2H3 OH is ideal as it can be easily converted to all-gas state; possesses hydrogen radicals which are readily dissociated which contain organic oxygen which can be easily combined with introduced hydrocarbon, radical hydrogen, and oxygen gases and vapours to produce pre-oxidized hydrocarbon gas vapours to be charged with negative electron ions to form into negatively charged pre-oxidized hydrocarbon gas vapours.

Another objective is to produce a chemical process which dissociates the hydrocarbon properties of the turpentine solution and allowing the essential oil to float on the upper level of the liquid mixture, thereby preventing the loss of alcohol.

The liquid mixture composition upon dissociation, are combined with these introduced hydrocarbon gas vapours and transformed into methane and ethane hydrocarbon gas vapours which is used to pre-ignite the vaporized fuel. The radical hydrogen, oxygen gases and vapours are transformed into a hydroxide and oxygen gas vapours to increase the oxygen content of the mass of air ratio in the combustion chamber to improve the ignition of fuel in an internal combustion engine.

By improving the mass of air to mass of fuel ratio with the negatively charged pre- oxidized hydrocarbon gas vapours, the combustion deficiencies such as pyrolysis, detonation, overheated valves, cylinder oil wash down and build up of carbon deposit are improved during the combustion process resulting in high efficiency engine performance, high thermal efficiency, increased engine power, conservation of energy and fuel consumption.

Another objective particularly, but not limited, the negatively charged pre-oxidized hydrocarbon gas vapours which form into compound elements to absorb heat in the combustion chamber of an internal combustion engine.

These and other objects of the invention will become apparent in light of the accompanying specifications, drawings and claims.

DETAILED DESCRIPTION The liquid mixture has to be used with the apparatus described in PCT/SG96/00022.

The apparatus is connected and takes hydrocarbon gas vapours from the fuel tank vent, radical hydrogen gases with hydrocarbon gas vapours from the positive engine crankcase vent and from the ambient air. The hydrocarbon gas vapours, radical hydrogen gases and ambient air are mixed and bubbled through the liquid mixture in the apparatus venting out gases of methane, ethane, hydroxide and oxygen gases which are then exposed to a negative ionization process adding negatively charged ion to these gas vapours and then fed into the air induction system mixing with the introduced air supply for combustion process of an internal combustion engine.

An alcohol solution comprising the lowest molecular weight alcohol-methanol is preferred as methanol, (CH30H) and/or ethanol, (C2H3OH) are more easily converted to an all-gas state.

Turpentine, (CloHl6) is preferred as a thinning agent for the oil fumes and hydrocarbon gas vapours from the positive crankcase ventilation of an engine. The turpentine solution contains oil essentials for regulating the hydrocarbon gas vapours venting out from the liquid mixture.

The turpentine solution is slightly soluble in aqueous alcohol, upon the mixture of these liquid solutions, the alcohol solution dissociates the hydrocarbon properties of the turpentine solution into ethane hydrocarbon gas formation.

The liquid mixture comprises 5% to 50% of methanol solution concentration, 2% to 15% turpentine solution concentration and distilled water with colouring is added to make up 100% of the solution.

The mixing procedure of the liquid solution is firstly, methanol or ethanol mixed with turpentine solution to chemically break down the hydrocarbon formation of the turpentine solution to form ethane with methane hydrocarbon gas vapours.

Distilled water is then added. Distilled water provides oxygen gas element with the ethane and methane gas elements. The hydroxides and methane are associated with oxygen radical from distilled water to form into pre-oxidized hydrocarbon gas elements.

By bubbling air, which contains oxygen gases, radical hydrogen gases which are easily associated with oxygen gas elements, and hydrocarbon gas vapours which associates with the methane and ethane gas element in the liquid mixture, within the apparatus described in PCT/SG96/00022 pre-oxidized hydrocarbon gas elements are produced.

Particularly, radical hydrogen gases are associated in the liquid mixture to form more hydroxide gas elements, and also hydrocarbon gas vapours are mixed to the liquid mixture to form chain reaction of hydrocarbon gas element combinations into a chemical gas formation.

The combination of air, hydroxide gases, methane and ethane gases, hydrocarbon gases in the liquid mixture produce pre-oxidized hydrocarbon gas vapours.

These vented hydrocarbon gas vapours from the liquid mixture are exposed through a negative ionization process which adds negatively charged ion electrons, transforming the hydrocarbon gas vapours into a negatively charged pre-oxidized hydrocarbon gas vapours which are fed through the air induction system of an engine added with the air to improve the mass of air to mass of fuel ratio, to improve combustion process of an internal combustion engine.
