MIXING DEVICE M Application filed July 9, 1928, Serial No. 291,235, and in' Brazil September 10, 1927.
This invention relates to a gaseous fuel mixing device for internal combustion en gines. More particularly it relates to various improvements in devices of this character and i p 5 has for its object the provision of a sultable device for utilizing the waste gases from the crank case of internal combustion engines. a In the crank cases of practically all internal combustion engines there eXist inflammable gases which arise in part through the leakage from the cylinders during the compression of the explosive mixture, and in part from the vaporization of the lubricating oils contained in the crank case, by the heat generated during the operation of the engine. :Usually these gases are Wasted and are not employed for any use or purpose such as in the operation of the engine itself.
It is the object of theipresent invention to provide a device whereby such gases. may be utilized in the engine in the crank case of which they are found. More particularly the present invention concerns a device whereby these gases are drawn from the crank case of the engine and after mixingwith a suitable quantity of airare supplied to the intake manifold of the engine, thereby aiding in the operation of the engine and eifecting an'economy in its fuel consumption.
understood reference is made to the accompanymg drawings wherein Fig. 1 1s a side View of a device in accordview on the line i i maybe attached in a suitable manner to an opening provided in the engine crank case.
At its other end the cylinder C is connected to a tube or conduit J intendedto be con nected to the intake manifold of the'engine. Within the tube C is arranged a piston P H andso mounted in a per- In order that the invention may be better.
waste gasesfrom gine, thedevice may be provided with an air valve or perforated disc G to permit the mix.- ture of a suitable quantity of air with the plan viewof-a detail of the.
forated closing it to a'fplurality of grooves R, which, as shownin 1 2, decrease in cro the inlet end to the ss-sectional area from outletend of the cylinder.
Accordingly'wh'en theengine to which the device is. connected isstarted the intake suction inder' O,,causing it to grooves of gradually tionalarea,
draws the piston]? upwardly in thecyl (cover portionsof the decreaslng cross secwith, the result that the waste gases supplied through 'the tubei'l are sup plied ingraduallydecreasing amounts to the tube J the furtherthe Wardly in the cylinder piston Pis moved up- C. Thus, in starting,
the intakesuction of the enginebeing at its highest value, thelpist to the upper limitiof its. strokein which position. practically shuts 'theigases intothe tube J During normal running, on the other on P is drawn almost ofl all passage of hand, or operation at high speed, .the intak eiisuction v-isfat a lower value, iri'which case thepiston P drops down to some point below its extreme limit, and in so doing allows a' round it through th times, therefore, the
passed into the tube J through thegrooves R is regulated or cont of the piston P portion of the gas to pass e groves B. At all 7 amount of waste gas rolled by the position which,'-i n'.turn, is sensitive to the intake suction of the engine. A proper mixture of waste gas with the ordinary fuel supply of the engine is therefore assured by the device.
In addition to the providing for a supply of crank case of the en waste gases prior to theinjection of the 1nixso as to bring a portion anifold of the engine. I end of thecylinder 0 a plurality of perfo-v witha similarly erfo be rotated or ad usted or all of its holes into a coincidence with the holes, or perforations,
in the end of the cylin der. After the disc'G has been adjusted to provide the proper amount of air it may be secured in position by means of a lock nut V.
Although the drawings illustrate but one form of the invention, it is to be understood that the device of the present invention may be variedi'n itsls'tructural detailsand size of parts,*i'n order to be applicable to various types of engines, Without departing from-the spirit andscope of t he .inve ntion as defined by the follovviiig' clailns'i I claim 1.
