JOHN A. SECOR, OF LAPORTE, INDIANA, ASSIGNOR TO ADVANGE-RUMELY COMPANY,
OF LAPORTE, INDIANA, A CORPORATION OF INDIANA.
REA'IO'MIZER.
Original application filed June so, 1919, Serial No. 307,682. Patent No. 1,430,989, dated January it, v
1924. Divided and this application filed December 21, 1922. Serial No. 608,281.
To all whom it may concern:
Be it known that I, JOHN A. Snoon, a
citizen of the United States, residing at La- ,porte, in the county of La Porte and State of Indiana, have invented a certain new and useful Improvement in Reatomizers, of which the following is a specification.
My invention relates to improvements in fuel mixing and particularly has reference to a reatomizing device whereby fuel which has been mixed with air is remixed or reatomized upon its introduction into the cylinder in which it is to be used. This application is a division of my co-pending application Serial Number 307,682, filed June 30, 1919.
It is, of course, well-known that when liquid fuel is aspirated by a rapidly moving current of air, the sudden change in ve- 'looity of the liquid and the sudden change in the pressure to which it is subjected among other forces, results in more or less comminuting or atomizing the liquid so that it readily mixes with the air to form a combustible fluid.
Experience shows, however, that particularly with heavier fuels, such as kerosene and the heavier fractions or distillates, you' are likely to have difficulty in that the fuel which is caught up by the air may be redeposited along the walls and passages through which it travels and particularly is this the case after the combustible mixture has passed by a throttle valve. the throttle valve tending to change the direction of flow, and to separate out the fuel so that you may even get an actual stream of liquid running down the walls of the passage, which stream of liquid has been taken M9 out of a satisfactory mixture by the mere presence of the partially closed throttle valve.
This difliculty is also present when you are using water as a part of the combustible mixture, and it is, of course. quite undesirable that this liquid fuel or liquid water be allowed to get into the cylinder in anything but a gaseous or finely divided condition, both because either the liquid fuel or liquid W water hinders the combustion and because liquid ingredients in the cylinder are likely to cause dilution of the lubricant in the crank My invention therefore takes the form of a device or devices which have for their purpose to reatomize the combustible liquid, or water and mix or assist in the mixing of it with the air.
My invention is more or less diagrammatically illustrated in the accompanying draw-f tion in the top of the cylinder.
Like parts are designated by like characters throughout.
A is a part of the engine cylinder casting, which as here shown includes an inlet passage A Seated within the end of this passage and communicating with the cylinder is an inlet valve B mounted on the valve stem B B is a bevelled valve seat in which the valve B is seated to close it. B is the reatomizing member. It is formed here integral with the valve seat, although its construction might be v-aried. B is a closed trough formed in the member B. open toward the upstream side, that is in the direction of the incoming fuel. As here shown itii is preferably provided with a sharp inner e ge.
C is a fragment of the engine cylinder casting which may be of any suitable form and is here provided with an inlet passage C D is an inlet valve carried by a valve D is a bevelled seat in which the stem D valve is seated when closed. D is the reatomizing device and is provided with a trough D which is open only toward the incoming fuel and is preferably provided as here shown with a sharp inner edge.
Although I have shown an operative device, still it will be obvious that many changes in size, shape and arrangement of parts might be made without departing materially from the spirit of my invention; and I wish therefore that my showing be taken as in a sense diagrammatic. Particularly the valve might be seated independent of the reatomizing device, and the valve seat and the reatomizing device would in that case be separate members.
' duction of the fuel into the cylinder where it is to be burned. The mixed fuel is then conductedto the engine cylinder through an inlet manifold or passage of any suitable sort. During its movement from the point of mixing to the en ine cylinder some of the fuel may be deposited out of the air cur rent in the form of drops- This is particularly likely to occur where the fuel is comparatively non-volatile, but it does occur in the case of almost every fuel. When such fuel is deposited out of the air current, itis in the form of drops which formupon the walls of the inlet passage. Such drops will be carried toward the inlet opening by means of the air current and in usual constructions will frequently be carried into the combustion chamber in liquid form. This introduction of liquid fuel into the cylinder results in unsatisfactory and unequal burning and is to be avoided.
In the construction shown there is provided about the inlet opening and closed to it a trough, open on one side toward the incomingstream of fuel, and closed elsewhere. The drops of fuel which have been deposited on the walls of .the inlet chamber and passage are gradually carried down and into this trough andas they accumulate, they fill the trough and overflow the edges of the trough. As the fuel overflows the edges of the trough, which are preferably sharp, it is seized by the air current and is broken up and again atomized, and so in its reatomized form joins the mixed fuel stream and is carried into the engine cylinder in satisfactory condition for burning.
