METHOD OF USING ULTRA-VIOLET RAYS TO AID THE PROCESS OF COMBUSTION IN COMBUSTION MOTORS, ETC.
Application filed May 29, 1926, Serial N'o. 112,732, and in Germany June 6, 1925.
Although ultra violet rays have been known for a long time no definite results have been found up to the present time regarding their'mode of acting in processes of 5 combustion. In creating ultra violet rays ozone is formed abundantly, that is in relation to the spent energy. For instance these processes and results can be used effectivelyin combustion motors. Another well known fact is that in ultra violet light the electric luminous arc becomes much larger, because the influence of ultra violet rays magnifies the conducting power of the air through ionization. This process is also employed here, for instance in a well known type of combustion motor.
In the drawing illustrating the invention,
Figure 1 is a partial section through a com-' plug A is effectively closed by a foil 0,
This foil C is made of material which is penetrable by ultra violet rays and so admits said rays into the plug-body A. The electrodes 0" and 0 are placed in the usual way, i. e. they face each other directly. The real apparatus to generate ultra violet rays B is directly over the disk C and is placed in a tube D. I
i .As the ultra violet rays generate ozone, it is projected into the air intake manifold or tube D and toward the zone of the igniter or plug A. Tube D is connected with the suction pipe of the carburetor so that the motor draws a definite quantity of ozone into the combustible mixture with every stroke. The amount of generated ozone can of course be regulated by throttling i. e. by controlling the amount of electrical current utilized in producing the same, the ozone generated being in proportion to the energy expended. This accelerates the process of combustion, considerably increases the number of revolutions of the motor. renders the combustion more perfect and thereby burns the fuel most efiiciently. Furthermm'e the points of the electrodes 0 and can be spaced apart a greater distance without using more energy and in this manner the danger of excessive clogging of the spark plugs is reduced to a minimum.
While the normal distance between the points of the electrodes is about 0,3 mm., they can now be spaced apart up (.03 mm. or more.
The same procedure, which has been mentioned here in regard to combustion motors, can also be employed in other methods of combustion. The ultra-violet rays can be projected into the combustion chamber by the same way by employing a reflecting mirror, causing the generated ozone in st-atu nascendi'to combine with the combustion air. There is only this difference, that in the combustion motor the process takes place under pressure and is caused in regular periods by electricity whereas in combustion the process is continuous.
