DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention refers to a combustion air improving device that promotes the combustion efficiency of internal combustion engines or general combustion equipment such as boiler and incinerator, thereby contributing to the purification of exausted gas.
BACKGROUND OF THE INVENTION
Techniques adopted generally to promote the combustion efficiency of internal combustion engines, are computer-aided combustion conditions control techniques, such as electronic fuel injection system and electronic control addition system.
In an attempt to raise the combustion efficiency, another technique has recently been proposed which makes a cluster of fuel particles finer by use of electrical stimulus, ultrasonic radiation, or UV illumination, reducing the viscosity of fuel along with enhancing its sprayability. There is, however, a problem of expensiveness in computer control not only because the single device itself is costly but also because a simultaneous installment of treatment means for purification of exausted gas forces is frequently employed. In addition, the computer-aided techniques are not free from fear of failures in the electronic circuit.
On the other hand, the prior art for quality improvement of fuels involves too many unstable factors in practical use: e.g. The action becomes indefinite depending on some combustion conditions or some fuel types. The improved effect is lost prior to suction of air into the combustion chamber.
With these problems of prior art in mind, therefore, it is the primary object of the present invention to provide a device for enhancement of combustion efficiency and for purification of exausted gas by improving the quality of combustion air.
Also, it is another object of the present invention to provide a combustion air quality improving device for internal combustion engines or general combustion equipment that can be produced at a low cost and ensures enhancement of the combustion efficiency regardless of fuel types.
Further, it is still another object of the present invention to provide a combustion air quality improving device for internal combustion engines or general combustion equipment that enables a stable action to be expected almost permanently.
DISCLOSURE OF THE INVENTION
A device according to the present invention is equipped with a casing made of magnetic materials in a shape of an elongated box. The casing has an air inlet on one end face and an outlet on the other end face in the front-to-back or longitudinal direction, an air duct communicating the inlet with the outlet is formed inside thereof, and is used in such a manner of having the outlet fixedly connected to an intermediate point of the suction air duct for combustion air in internal combustion engines or general combustion equipment. In the casing, permanent magnets are fixed with the same poles opposed to each other so as to sandwich said air duct therebetween. Also, shaft members made of magnetic materials are transversely disposed in the air duct. Further, around the shaft members, first and second cylindrical members made of metals different in ionization tendency are fitted loosely with a gap between each other. These cylindrical members are freely moved due to the air flow passing through the air duct. During idling of internal combustion engines, for example, air may be forced into the device from the air inlet via a fan motor.
Within the air duct, consequently, a strong magnetic field is formed in a direction perpendicular to the flow of combustion air under cooperative action of the permanent magnets together with supporting shafts that are magnetized through the casing wall by the magnetic force of these permanent magnets. The magnetic field is made still firmer by covering all other surfaces than the surfaces of the permanent magnets facing to the air duct and those opposite thereto with magnetic insulation members.
First and second cylindrical members loosely inserted through around the supporting shafts are also situated within said magnetic field. The cylindrical me
