boirMotora ot which the following is a which also utilizes t specification.

This invention relates to hydrocarbon nio tors, and particularly to cylinder jacletrcon structions theretor.

Une ot the objects ot this invention is to provide an iinprored dispositio and arrangement ot the motor cylinder gas passages. -1 l Another object of this invention is to pro- Vide improved means tor e'lliciently heatiiur and imporizinghydrocarbon fuels, and torconductingr and distributing the gaseous mixture to the cylinder combustion chamber.

Another object of' this invention is to provide a V motor having its cylinder ,intake and exhaust passages so arranged that rarious parts ot the motor, such the yalves,

and other driving mechanism are rendered very'accesssible thus providing' lor easy en@V animationassembling and disassexnhling` ot i these parts.

Another object ol thisinvention is to pro vide an arrangement of niotor passages which permite the utilization ot the heat ot' exhaust gases `noriaing the fuel, and

lie cylinder cooling' mcdiuln lfor qualifying the heating effect ot said gases on said it'uel.

These, and other objects, will clearly ap# pear from the tollowing; description, taken in connection with the accompanying drawings, which form a part ot' this specification, and in which:

cam shaft l2. A plurality of cylinder blocks 13 and 14, respectively, may he arranged in V relation on the crank cz se 10 and secured thereto asby bolts 15. Each bloclr comprises a plurality ot cylinders 1G, surrounded by an integral jacket 17. Each cylinder has formed in its inner face a valve intake port 18,'and an'exhaust valve port 19, adapted to be controlled by Well known puppet valve mechanisms 20. 4The valve mechanisms are adapted to be operated in any Well known manner from the cam shaft 12 within the crank case 10.

A gas intake or distributing passage 21, is cored out ol a conduit 22, 'formed integral with, and arranged Within, the jacket 17.- rlhe intake 21 is provided With a port 23 at the inner 'lace orp the cylinder block and has ports leading to valve chambers 24. A T shaped conduit and Iarloureter 23", may be arranged between the blocks 13 and 14, with its outlets suitably connected to the inlet ports 23.

An exhaust passage 25 is alsoltornied in the conduit 22 below the intake passage 21, with only a comparatively thin longitudinallyextendingr dividing wall 6 therebetween. The exhaust passage is in conH stent communication with cylinder exhaust valve chamber ports 19, and is provided with an outlet branch 27 formed intermediate the ends of the blocks 13 and lhand extending transversely thereof from the jacket inner face to the other face Where the ,erases may be discharged exteriorly of the cylinder block through a port 28.

`lilxhaust pipes 29 may be suitably secured in position along;- the outside oi: the block in communication with the ports lt will be noted that with the foregoing; arrangenients.y the incoming gases are adapted to be distributed to the various cylinders after tlowing through the passage 21, the bottom ol" which is formed by a dividingr wall 26 below which the esha ust gases are discharged from the cylinders, with the result that the heat oi the outgoing exhaust gases will be imparted to and insure the vaporization of the 4llydrocarbon i'uel passing through the intake. li' any oit the heavier hydrocarbon incl elements are precipitated or condensed within the gas intake passage 21, the heat of the dividing' Wall 26 will tend to immediately volatilize these elements.

Where it has been attempted heretofore,

to utilize` the heat of the exhaust gases for improving the vaporization of the hydrocarbon fuel, considerable difficulty has been experienced, on account of the decrease in volumetric elliciency, and the fallingr off in power, of the motor caused by the undue expansion of the incoming chargil of gas. ii'lhich. of course. results in diminishing the weight of each charge. .These difficulties have been overcome, in this invention, by so arranging the intake and exhaust passages that the heating effect .of the .exhaust gases on the fuel mixture 1s qualified b v the temperature of the surrounding cooling medium Within the jacket. In other Words` assuming that the exhaust gases have radiated siiliicient heat through the dividing ivall 26, to vaporize the previously condensed hydrocarbon fuel within the intake passage 2l, the surrounding cooling medium Within the jacket 17 will also maintain the temperature of the incoming charge belov:

lthe desired limit.

It is to be also noted that by my improved means for conducting -the exhaust gases from the inner to the outer faces of the blocks of a V type motor. and arranging the exhaust pipe along the outer face, the space between the inner faces of the blocks is left entirely free and unobstructed, save for the carbureter and intake, which may be easily removed. By `removing the carbureter and "intake, the space between the cylinder blocks Will be entirely free from obstructions. thus permittiingv very easy adjustment and disassembly of the various valve mechanisms and their driving parts. I

It will be understood, of course` that vari,- ous modiiications and changes will occur to those'skilled in the art, Without departing from the spirit and scope hereof.

Having thusdescribed my invention, what claim and desire to secure by Letters Patent is:
