These coi'npartments' of the exhaust manifold are separated by a longitudinally extendingwall 12.

- curved portion 21 of the pipe 20,-a n' air inlet ah-e30 is mounted upon the wallet the exhaust manifold, said'valve being normally closed. The upper end of the valve stem-31.-

2g is closely contiguous to the; extremity of the expansible element 21. Inj the operation of heldevice, the mix- 'jtureof kerosene and air enters from the pipe lef into the-chamber. 13 and,'fromsaid 25 is admitted to the upper-compartment -9 of the exhaust manifold, and'bycontact of the I. the electric. circuit is closed-'andthe tubular rod Z-l thus becomes very highly heated and the end portion of this rod projecting into the intake manifold; furtherheats the mixture as .it enters the intake manifold. This heatedminture will also heatthe pipe 19 and the. water contained therein. As the l "pand as it is not" desirable to heat the in.-

terior. ofjthe manifold above a certain degree, say '150.1,' at-which temperature the kerosene vapors would become separated or dissipated so that a. good combustible m1X v turewould not be obtained. Upon the ex-- pansion of this water-filled tube 21, the contact is moved away from the contact '28 and the electric circuit-is broken.v This end ofsaidtube will almost immediately engage with the valve stemv 21. and opens the air intake valve '20sathatatmosphric air may enter the inlet manifold, thereby reducing theteniperature of the, same. :Thus, the

gaseous mixture passing through the intake manifold ismalntalned at a constanteven temperature. I have found ln'actual practice that, by the provision "ofthe flat tubes or conduits 16, the kerosene is thoroughly vaporiz'ed, as an extensive surface is afi'orded withwhich the'exhaust gases from the err: gine cylinders may contact. By the provision' in addition, of the electrically heated chamber, passes through 'the'severa-l' pipes .16. The exhaustfrom theenginecylinders highly heated burned gases with these pipes,-

rod extending intothe intake manifold, the .possibility of solid'or unvaporized constit- 'haust and-intake manifolds as shown, and

. tensive surface exposed to the exhaust gases, the mlxture willfirst be heated to a hi 11 so that, by the additional heating of the intake manifold through the medium of the electrically heated tubular rod extending within thefsame, the inadequacy of vaporizers of this type forthe purposeof utilizing the lower grades'of hydro-carbon fuels, is

overcome. throughthe lower compartment 11 of the manifold are exhausted through the ordiln'ary'mufiler to the'atmosphere. v r

-ing, it is believed that the construction, manner of operation, and several advantages of the invention will be clearly and a fully understood. The device, while exceedingly simple. in its construction, has been found by repeated tests'to b highly rially reduce the operating cost of motor .vehicle engines by the use of a low grade hydro-carbon fuel'such as kerosene which is relativelyinexpensive. I have also demonstrated that, by means of the present invention, kerosene may be used as fuel without any reduction of power over thatqobtained by the use of gasolene, and in some instances .the power obtained was even increased.

it will, of course, be understood that the manifold construction, as well as the mounting and arrangement of the electrically .heated tube and the expansible circuit closer and valve opening device maybe changed as desired, in accordance with the particular type of engineupon which the device is to be employed. I, therefore, reserve the privilege of adopting all such legitimatemodifications as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what Idesireto claim and secure by Letters Patent is;:

The combination with an internal combus tion engine having intake and exhaust ports, of 'anexhaust manifold having upper and lower compartments, said upper compare. ment-being'connected to the exhaust ports,

said manifold being provided with an inlet chamber at one end of the upper c0mpart ment; a intake manifold centrally] located within the lower compartmentand connect ed tothe intake ports of the engine, and 1a plurality of transversely elongated con: dil it's in communication stone of their ends 'with vsaid inlet I chamber and extending through. the upper compartment and into,

said conduits being connected to the intake manifold. v
