Spark plug ultrasound whistle

A plurality of ultrasound whistles formed into a ceramic core of a conventional spark plug used in a cylinder of a gasoline combustion engine for greatly improved air fuel mixture prior to ignition. The spark plug with ultrasound whistles provides for increased engine performance and acceleration, improved fuel mileage and an improvement cleaner burning air fuel mixture thereby providing for reduced fuel emissions into the environment. The ultrasound whistles are constructed in the form of whistle holes. The whistle holes are disposed around a circumference of the ceramic core in a spaced relationship and next to the spark plug's electrode. The holes have a depth in a range of 0.032 to 0.050 inches. Also, the whistle holes have a diameter in a range of 0.031 to 0.033 inches. Around the top of the small closed end whistle holes are upwardly extending lips. The upwardly extending lips have a height above the surface of the ceramic core of 0.015 to 0.040 inches. The combined structure of the size of the whistle holes in the ceramic core and the upwardly extending lips accelerate the air fuel mixture from 100 feet per second to when ignition occurs in the engine, the ignition rate or burn rate is driven into an ultra sound frequency range of 5000 cycles per second. The increased speed of the air fuel mixture creates a greater and more homogenous air fuel mixture prior to and during ignition in the engine cylinder.

BACKGROUND OF THE INVENTION 
(a) Field of the Invention

particularly, but not by way of limitation, to a spark plug with a 
plurality of whistles for improving air fuel mixture prior to ignition and 
during ignition in a gasoline combustion engine.

3,914,353 to Cherry various types of ultrasonic fuel injection devices and 
atomizing fuel inventions are described. None of these prior art patents 
disclose or teach the use of ultrasound whistles disposed in the sides of 
a ceramic core of a spark plug for improved gasoline engine performance 
and added benefits described herein. 
In a text book published by McGraw Hill, 1960, titled "Whistle Ultrasonics" 
by Benson Carlin, whistle type ultrasound is described operating in a 
range of 5000 to 10,000 cycles per second. The frequency wave length for 
ultrasound is 8 inches in solid material, 2.4 inches in liquids and 
approximately 0.63 inches in atmospheric air. The type of wave produced by 
whistles are longitudinal and "L" waves. An ultrasonic wave in a gas or in 
an air fuel mixture starts out as a longitudinal wave and when it strikes 
particles of fuel, it turns into a "L" wave. The more particles of fuel 
the "L" wave hits, the more excited it becomes. When the "L" wave strikes 
the side of a spark plug and any other metal surface in it's path, the 
wave is amplified twice. The more surfaces the ultrasound wave strikes, 
the greater the acceleration. When sound waves are traveling through 
various mediums, the waves are reflected, refracted, defracted, scattered 
and multiplied. Like any whistle sound, the more air that crosses the 
whistle, the more the volume it produces. Today, ultrasound is used in a 
variety of industries for cleaning, metal testing and like applications. 
SUMMARY OF THE INVENTION 
In view of the foregoing, it is a primary object of the subject invention 
to provide a conventional spark plug with ultrasound whistles for greatly 
improved air fuel mixture prior to ignition in an gasoline engine. 
Another object of the invention is the spark plug with ultrasound whistles 
provides for increased engine performance and acceleration and improved 
fuel mileage, 
Still another object of the improved spark plug is to provide a cleaner 
burning air fuel mixture thereby providing for reduced fuel emissions into 
the environment. The formed whistles in the ceramic core will also extend 
the life of the plug under normal operating conditions. The plug is not 
subject to electrical erosion and the porcelin of the plug is designed to 
be self cleaning. 
Yet another object of the invention is to accelerate the speed of the air 
fuel mixture inside a combustion cylinder wherein the air fuel mixture is 
increased from 100 feet per second to an ultrasound range of 5000 cycles 
per second. The increased speed of the air fuel mixture creates a greater 
and more homogenous air fuel mixture prior to ignition in the engine 
cylinder. 
The subject invention includes ultrasound whistles constructed in the form 
of whistle holes in a spark plug. The whistle holes are disposed around a 
circumference of the ceramic core in a spaced relationship and next to the 
spark plug's electrode. The holes have a depth in a range of 0.032 to 
0.050 inches. Also, the whistle holes have a diameter in a range of 0.031 
to 0.033 inches. Around the top of the small closed end whistle holes are 
upwardly extending lips. The upwardly extending lips have a height above 
the surface of the ceramic core of 0.015 to 0.040 inches. The combined 
structure of the size of the whistle holes in the ceramic core and the 
upwardly extending lips accelerate the air fuel mixture from 100 feet per 
second to an ultrasound range of 5000 cycles per second. The increased 
frequency and speed of the air fuel mixture creates a greater and more 
homogenous air fuel mixture prior to and during ignition in the engine 
cylinder. 
These and other objects of the present invention will become apparent to 
those familiar air fuel mixtures in an internal combustion engine, the use 
of ultrasound and whistles operating in an ultrasound range of 5000 cycles 
per second and greater when reviewing the following detailed description, 
showing novel construction, combination, and elements as herein described, 
and more particularly defined by the claims, it being understood that 
changes in the embodiments to the herein disclosed invention are meant to 
be included as coming within the scope of the claims, except insofar as 
they may be precluded by the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
In FIG. 1, a perspective view of a standard spark plug having a general 
reference numeral 10. The spark plug 10 includes an ignition wire cap 12, 
a spark plug body 14, threads 16 for mounting the spark plug 10 in a 
gasoline engine motor block, an electrode 18 for igniting the air fuel 
mixture inside a combustion cylinder and an electrode ground 20 disposed 
next to an end of the electrode 18. A gap 21 is shown therebetween the end 
of the electrode ground 20 and a portion of the electrode ground 20. A 
circular ceramic core 22 is disposed around an upper portion of the 
electrode 18. The ceramic core acts as an insulator for the electrode 18 
during the ignition of the air fuel mixture. The downwardly extending 
exposed end of the electrode 18 typically has a diameter in a range of 
0.060 to 0.10 inches. Formed in the ceramic core 22 are a plurality of 
ultrasound whistles 24 making up the subject invention. 
In FIG. 2, an enlarged side view of a lower portion of the spark plug 10 is 
shown illustrating the ultrasound whistles 24. In this view the whistles 
are shown disposed in the side of the ceramic core 22 and in a spaced 
relationship to each other. The number of ultrasound whistles may vary 
from 3 up to 12 or more. In the gap 21 are broken lines 23 used to 
illustrate the ignition and burning of the air fuel mixture at the end of 
the spark plug 10. 
In FIG. 3, a greatly enlarged side view of the lower portion of the spark 
plug 10 is illustrated wherein the ultrasound whistles 24 are shown in a 
spaced relationship to each other and disposed around the circumference of 
the ceramic core 22. The electrode ground 20 is not shown in this drawing. 
In this view, the whistles 24 are shown made up of a plurality of whistle 
holes 26. The whistle holes 26 have a diameter "D". The diameter "D" may 
be in a range of 0.031 to 0.033 inches. The whistle holes 26 have a closed 
end. At the top of each hole is a raised lip 28 therearound which is used 
to increase the speed of the air fuel mixture as it passes over the top of 
each whistle hole 26. 
In FIG. 4, a greatly enlarged front view of the ceramic core 22 is shown 
with the ultrasound whistles 24 with whistle holes 26 in a spaced 
relationship to each other and disposed around the circumference of the 
ceramic core 22 and around the outwardly extending end of the electrode 
18. 
In FIG. 5, a greatly enlarged cross sectional view of a portion of the 
ceramic core 22 is illustrating. In this view, the ultrasound whistle hole 
26 is shown formed in the ceramic core 22 with the whistle hole 26 having 
an upwardly extending lip 28 disposed around the top of the hole 26. The 
height of the lip 28 above the surface of the ceramic core 22 is 
approximately 0.015 inches. The hole has a depth "d". The depth "d" is in 
a range of 0.032 to 0.050 inches. 
Also shown in this drawing are long arrows 30 which illustrate laminar flow 
of a typical air fuel mixture prior to passing over the top of the whistle 
hole 26 and having a typical speed up to 100 feet per second prior to 
combustion. Short arrows 32 illustrate what starts out as a longitudinal 
wave and then when the sound wave hits an air fuel particle it becomes a 
"L" wave. As the "L" waves 32, as shown in FIG. 5, hit additional air fuel 
particles, the speed increases with added turbulence and increased mixing 
of the air fuel mixture at ultrasound frequencies in a range of 5000 
cycles per second and greater. This important feature provides for an 
increase of 500 per cent in the air fuel movement past the spark plug 10. 
When the air fuel mixture represented by arrows 30 passes over the top of 
the whistle hole 26, a vacuum is draw therein. With the lip 28 around the 
top of the hole 26, the laminar flow of the air fuel mixture is broken up 
and turbulence is created. With the turbulence of the air fuel mixture, a 
more complete mixture of the air and fuel occurs. Also, the air fuel 
mixture accelerates thus creating, as indicated by the "L" waves 32, a 
more homogenous air fuel mixture prior to ignition. The use of the 
whistles 24 on the ceramic core 22 provide, as mentioned above, for more 
rapid fire and efficient burning of the fuel thereby greatly reducing fuel 
emissions into the environment. 
In the testing of the subject invention, a gas engine operates at various 
densities and pressures. In the combustion chamber of the engine and at 
the time just before ignition occurs, a maximum density and sound 
frequency using the whistles 24 is reached with a wave length of upward to 
2.0 inches. This increase of wave length with the "L" waves 32 provides 
for greater turbulence and mixing of the air fuel mixture prior to and 
during ignition. When ignition occurs, the pressure in the chamber 
escalates along with the ultrasound frequency produced by the whistles 24. 
The increase in sound frequency drives the burn rate upward into a range 
of 5000 to 10,000 cycles per second. This is compared to a standard gas 
engine operating with no ultrasound frequency and at a burn rate of 100 
feet per second. 
With a gas engine using the ultrasound whistles and operating at a burn 
rate of 5000 to 10,000 cycles per second, fuel efficiency improves by 35 
to 50 percent with 50 percent reduction in emissions and improved engine 
horsepower in a range of 25 to 40 percent depending on the rpm of the 
engine. 
While the invention has been shown, described and illustrated in detail 
with reference to the preferred embodiments and modifications thereof, it 
should be understood by those skilled in the art that equivalent changes 
in form and detail may be made therein without departing from the true 
spirit and scope of the invention as claimed, except as precluded by the 
prior art.
