CARBURETER ATTACHMENT.
Specification of Letters Patent.
' Application filed January 11, 1911. Serial No. 602,011.
To all whom it may concern Be it known that I, JAMES OMAY, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Carbureter Attachments, of which the following is a specification.
The subject matter of this invention is a device for increasing. the efficiency of the fuel charge in any internal-combustion engine using gasolene or similar liquid fuel; and it consists in a special form of perforated plate or screen adapted to be disposed across the delivery-conduit leading from the carbureter to the supply port of the engine.
It is well understood by those skilled in the art of internal-combustion engines that the efliciency of the charge is promoted by effecting as fine a division as possible of the oil, and as thorough and as properly proportioned a mixture as possible of the same with the air; and various devices for these purposes have been proposed.
The main object of my invention has been to provide a device of this character that would be characterized by extreme simplicity and cheapness of cost and a high degree of efficiency for its intended uses or purposes.
After considerable experiment I have discovered that by placing across the path of' travel of the charge between the carbureter and the engine a perforated plate or screen so formed that the perforations or apertures therein present comparatively sharp or rough edges to the charge impinging thereon, the globules of oil in the charge are broken up and subdivided, and the current of air is also minutely subdivided, the result of the two being a more thorough and complete intermixture of the oil and air and a consequent considerable increase in the eflEiciency of the charge.
In the accompanying drawing I have illustrated my invention as applied to one well known form of carbureter, but it will be understood that the device may be applied to any form or type of carbureter or charge-forming device, or may be located anywhere in the usual pipe connection between the carbureter and the supply ,port of the engine.
Referrin to the drawing, Figure 1 is a side elevational view of a carbureter and its delivery-pipe, showing my improvement applied thereto; the parts at the point of application of the improvement appearing in vertical section. Fig. 2 is a topplan view of the upper gasket and underlying perforated plate. Fig. 3 is an enlarged sectional detail through the perforated plate, more particularly designed to show the rough or sharp edges of the apertures in the latter on that side which is toward the incoming charge.
Referring to the drawing, 5 designates as an entirety a carbureter of a well known type, and 6 the delivery pipe leading therefrom to the supply port of the engine. At the point where the delivery-pipe 6 is coupled to the discharge end of the carbureter I interpose a plate or diaphragm 7 provided with a large number of comparatively minute perforations 8. These perforations may be formed by punching, drilling, or otherwise; but in any case the natural result of a perforating tool being to form comparatively sharp and rough edges around one end of the perforations; such sharp rough edges being indicated, in a somewhat exaggerated form at 8 in Fig. 3, thesame being formed on that side of the plate 0 posite the side which the perforating too enters and on which the in-coming charge impinges. To render the joint perfectly tight, the plate 7 is clamped between a pair of rubber or other gaskets 9, these latter in turn being securely clamped between a pair of collars 10 and 11 on the pipe 6 and carbureter 5, respectively; the collars 10 and 11 being securely united as by bolts indicated at 12. It will be noted that the perforated plate "7 is so located that the rough or sharp edges 8 of the perforations 8 lie toward the incoming charge.
I have found that, as a result of the described construction, the oil spray from the carbureter, immediately after it is caught by the air current, is met by the perforated 100 Patented Dec. 30, 1913'.
and not being thoroughly consumed in the no engine because oftheir size and the rapidity with which they enter and pass through the combustion chamber, are either thrown out unconsumed and passed off in the exhaust, or are consumed in the exhaust pipe, heating it, and thus increasing back-pressure as Well as producing a considerable element of waste. By the use of my invention these globules or drops are dashed against the sharp edges of the perforated plate or screen and are thereby broken up into smaller drops, thus producing a more perfect commingling of air and oil vapor and also, by means of smaller drops, presenting more oil-film area to the ignition charge in the combustion-chamber. This eflects a .considerable economy in fuel by utilizing the increased combustion in the cylinder instead of wasting it in the exhaust pipe.
Actual tests of my invention on both light and heavy motor cars have shown an increase of efficiency of from 12% to 35% under varying conditionsas compared with the results obtained from similar tests with the same cars not equipped with the invention.
Among the advantages attained by the invention may be mentioned a considerable saving of fuel, a reduction of the heat in the exhaust pipe thereby reducing back pressure and danger from fire, the prevention of the flooding of the engine with con-,- siderable quantities of unmixed oil and a consequent lessening of the liability of carbonlzmg the engine, greater elasticity in the sudden changes of the combustion charge, and the comparatively trifling expense involved in the manufacture and installation of the device. 7
I am aware that it has heretofore been proposed to interpose a wire mesh-screen across the path of the charge leading from the carbureter to the supply port of the engine, but I have found by comparative tests that such a screen does not effect the advantages and results hereinabove described as pertaining to the device of my invention.
I claim,
1. In a charge-forming device for internal-combustion engines, the combination with a carburetor anda delivery conduit leading therefrom to the supply port of the engine, of a perforated plate or screen interposed across said delivery conduit, the perforations of said plate or screen being so formed as to present rough or sharp edges toward the charge impinging thereon, substantially as described.
2. In a charge-forming device for internal-combustion engines, the combination with a carbureter, of a delivery pipe, a coupling connecting the latter to the discharge end of the carbureter, and a perforated plate or screen fitted gas-tight in said coupling across the end of said delivery pipe, the perforations of said plate or screen being so formed as to present rough or sharp edges toward the charge impinging thereon, substantially as described.
