ABSTRACT:
FIELD OF INDUSTRIAL UTILIZATION
The present invention relates to a fuel catalyst apparatus for exhaust gas purification which decreases toxic substances included in the exhaust gas of internal combustion engines, by interposing a catalyst in a fuel pipe connecting a fuel tank and the internal combustion engine and charging the fuel with negative electric charges thereby improving the combustion efficiency, to be used in the field of exhaust gas purification for internal combustion engines of automobiles, watercraft and aircraft.
BACKGROUND OF THE INVENTION
In the automobile industry, a three way catalyst installed in the exhaust pipe of an internal combustion engine is commonly used for post-treatment of toxic substances discharged from the internal combustion engine. This process is employed in lean-burn engines of higher combustion efficiency, direct injection diesel engines and direct injection gasoline engines.
PROBLEM THE INVENTION AIMS TO SOLVE
It has been a problem in this industry to find a solution to eliminate toxic substances from the exhaust gas of an internal combustion engine. As it is impossible to eliminate 100% of the toxic substances with the prior art technologies, the toxic substances in the exhaust gas can be decreased further by adding an apparatus of the invention to the prior art technologies as required. The present invention is intended to provide a new type of catalyst for pre-burning treatment and make contributions to the cause of environmental conservation.
MEANS FOR SOLVING THE PROBLEM
It is an object of the exhaust gas purifying apparatus of the invention to provide a fuel catalyst apparatus for exhaust gas purification wherein a catalyst device is installed to provide negative electric charges to liquid petroleum fuel which is sent through a fuel pipe running from a fuel tank to an internal combustion engine.
This makes it possible to improve the combustion efficiency of the fuel through catalyst treatment before burning in the internal combustion engine and decreases the toxic substances discharged from the internal combustion engine, thereby contributing to the cause of environmental conservation and savings in fuel consumption.
Another object of the invention is to provide a fuel catalyst apparatus for exhaust gas purification wherein an electrode is installed in a fuel pipe and a negative electric charge output terminal of a static electricity generator installed outside the fuel pipe is connected to the electrode with a lead wire, as a catalyst device.
According to the invention, a negative electric charge is generated in the fuel pipe from the negative electric charge output terminal of the static electricity generator, thereby charging the fuel with negative electric charges and achieving the object.
An additional object of the invention is to provide a fuel catalyst apparatus for exhaust gas purification wherein the catalyst device is a cylinder containing a substance that easily charges positively such as tridymite, nylon or silk and is disposed in the fuel pipe, while liquid fuel passing through the fuel pipe is brought into contact with the substance.
This makes it possible to charge the fuel negatively via the positively charged substance, thereby achieving the object.
Furthermore another object of the invention is to provide a fuel catalyst apparatus for exhaust gas purification wherein the cylinder is made of nylon which easily charges negatively while the cylinder and a portion of the vehicle body equipped with the internal combustion engine such as a shroud disposed besides a fan that easily charges positively are electrically connected, thereby supplying negative electric charges to the cylinder.
This makes it possible to supply negative electric charges intermittently and effectively to the cylinder and charge the fuel negatively, thereby achieving the object.
The above and other objects and effects of the invention will be made apparent from the description that follows.
