. INTERNAL-COMBUSTION ENGINE.

' Internal- Combustion Engines, of which the following is a complete specification.

This-intention relates to means for properly effecting the vaporization and mixing of the charge before-being introduced into the combustion-chamber, and is designed. more articularly for application to engines using w gra'i'ity 0115, such as kerosene and crude Therobject in view is to secure a mo'rsprfect mixture andcoinbustion of the char e,

and hence ahighe'rfuel' efficiency, and a so to o'x'ercoine the severe shocks or concuslesions usually attending t u e of heawy oils B'Xplosive engines;

, The results above mentioned are largely secured readmitting a relatively sma portion oftheexhaust gasto the combustion chamber and utilizing ,-th.is ortion so readmitted both to draw in an to heat-the oil for the charge. 7 Th preferred construction of the improvement. is illustrated in' the accompanying drawings, in which- 1 Figure '1 represents ar'ea'r viewof the cylinder of an engine with the improved vaporizer appearing partially in side elevation and i c derwith the vaporizer appearing in end- -e ovation.

eating, through the vertical chaiiiiel 6 and the transfersely extending channel 6 (see' The supply and overflow pipes exhaust pipe 2, and the exhaust channel thereof in effect constitutes a portion of the said exhaust pipe. The heating chamber comprises'the interior channel 11 for the exhaust gases which enter therein through the pipe 2 and discharge therefrom through a continuation 2 of'said exhaust pipe. Surrounding the exhaust channel 11 is a casing 12 inclosing the passageway through which the air is admitted to the: heating cham- The longitudinally extending walls 13, which terminate. a short distance fromflthe forward end of said heating chamber 10 and are arranged on either side thereof (seeFigs. 1 and 2), divide the said passageway into a lower channel 14, through which the air enters, and an upper channel 15, through which the air returns, as indicated by arrows in Fig. 1, and flows to. the cylinder through the airpassageway 3 and mixing chamber 4. At the airinet end of the heating chamber 10, and preferably formed integral therewith, is an air channel 16, which communicates directly with the air and fuel passageway 3.. A two-way plug valve'17 is arranged near the mouth 16 of the channel 16, and this plug valve is adapted to divert the incoming current of air either through the

channels

14 and 15 of the heating chamber, or by-pass it through the chamber 16' direct to the air passageway 3. When the han'dle '17 of the lug valve 17 occupies d by full lines in Fig.

1', the air will be directed through the heating chamber 10, but when in the position indicated by dotted lines the same figure, the air will be made to pass direct The inflow of oil through he nozzle 5 is regulated by means of the needle valve.

18, which is provided at its outer end with ortion or all of the exhaust 2 the milled thumb nut 18?. The amount of oil drawn from the nozzle the 'air current which flows through the assage way .3 is supplemented by an "a ditional amount drawn from said nozzle, by means of a jet of exhaust gas which is directed thereagainst.- A conduit 19 leadsjrom. the

interior of the exhaust gas channel, or

chamber, Ila-to a point closely adjacent to the nozzle 5, as clearlyshoWn-m :th'e several-figures. A jet of the-hot exhaust gases is thus projected against and over the nozzle, heating the same as well as the oil-drawn therefrom, thus securing a much better spraying eife'ct.

the mixing'chamber occurs simultaneously with the exhaust from the combustion chamber. This jet'of exhaust as is mixed with'the oil it draws in and the ot mixture ofinert gaspsa'turated with oil, fills the air passageway as well as the mixing chamber and imparts heat to the inclosing walls.

I The succeeding aspiratory stroke of the- 1enginew'ill first draw in this mixture of exhaust gas" and oil, which will be followed b fresh air and oil. The charge is thus formed of' two parts; viz, that initially bustion chamber, but it dilutesth charge,-

the combustion is less rapid and'the violence of the shocks is mitigated. 1

Instead of the conduit 19 extending laterally from. the exhaust pipe, it is ,made

to lead from an abutting surface therein against which the gas impinges, and hence a more forcible jet is obtained. Such abutting surface -is here formed by the end 11 of the chamber or channel 11.1f

In order to start the engine with k'eros'ene,-the air passageway is heated by'burn mg 011 or other combustible material the cure means of the straps 22 fixed thereon, as

(pan- 21, which can be detachably seshown by dotted lines in Fig. 1 the plug 20 of the vent 20 being removed. The vent 20 is provided in the wall of the mixing chamber between said nozzle and the com bustion chamber, and is normally closed by means of the plug 20 This 'vent is open to allow the flames to pass through The entrance of the. exhaust gases through the conduit 19 to to the mouth 16 of the air inlet by I :of the exhaust heat the oil therein. By thus heating the wallsof the mixing chamber and the nozzle .which contains the oil used to form the ad initial charge, the engine can be start without diflicult'y on kerosene.
