-' IHTER-NAL'COMBUSTION ENGIlEJE.
Application filed November 6, 1824. Serial Ho. $18,119.
' To all whom it may concern Be it known that I, JAMES Sources Boo'rn,
a citizen of the United States, residing at Detroit, in the county of lVayne and State 6 of Michigan, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.
This invention relates to internal combos Of course, in ant-head motor of the pop-' pet valve type, the exhaust and the intake are both on the same side, but in a T-head motor of the poppet valve type, and in nearly all sleeve .valve motors the exhaust and intake are on opposite sides of the cylinder block. lit .is not very convenient to transfer the exhaust gases from one side of the cylinder block to the other for forming a. so called hot-spot on the carburetoror the intake manifold. Such a transference induces diiliculties in a motor design which it is the object of the present invention to overcome.
, It is also desirable in an engine having a large number of cylinders, eight or more, to have two carburetors for supplying the fuel charges as this insures a more even distribution of the fuel charge and a better flow of power. I have therefore so coupled and laid out the arrangement of the duplex carburetor as to completely eliminate the difficulty of transferring the hot gases from one side of the cylinder block to the other.
I have further solved the difficulty introduced by a carburetor on each side of the cylinder block when an air cleaner is used. I surmount the air cleaner on top of the engine cover and connect the interior of the engine cover with each carburetor by suitable conduits. This eliminates the necessity of an air cleaner on each side or piping running over or around the engine block.
Referring to the drawings:
Fig. l is a plan View of motor design.
Fig.2 isaside elevation of the same.
Fig. 3 is a cross section of the motor.
Fig. 'l is a longitudinal section of the my improved same, taken substantially in the plane mt'ahe and exhaust ports.
The so-callcd straight eight places a large task on a single carburetor and it is found 111 actual practice that it is desirable to use 69 two carburetors to prevent the starving of the end cylinders. In place of supporting these carburetors a a on the same side of the cylinder bloclt as is the cush'nnairy pracface, I place one carburetor a on one side oi. @5 the cylinder block at the front and the other carburetor a on the opposite side of. the cylinder block at the rear. Freferably, these carburetors are located one midway between each set of cylinders fed by such carburetor, here shown as sets of tour. This assures a fairly equal distribution of the mixed fuel and air to tell the cylinders. This lay-out is well illustrated in Fig. and the details will be apparent with out specific enumeratioii. The manifold Z; divides'at the center and each end feeds apair of cylinders which here happen tc be shown as two-ported cylinders having sleeve valves.
The same arrangement obtains on the rear division of fourcylinders. Now it will be noted that each cylinder has two exhaust ports on the opposite side and these are connected through separate passageways c with the exhaust manifold 12, which has a plurality of branches e. Hence, the exhaust gases from the front set of cylinders serves to pre-heat the fuel charge for the rear set of cylinders, while the exhaust gases for the rear set of cylinders is carried by the manifold forward to the front intake manifold, which is provideduwith a suitable jacket f to hot-spot the intake manifold. It will be apparent that these exhaust gases can be used either to preheat the gases in the hianifold or to form a hot-spot around the carburetor, although as here illustrated, only the hot-spot on the manifold is shown.
In the higher grade cars it is now desir- I able to employ an air cleaner to separate out the suspended particles of dust and grit which would otherwise be drawn into the cylinders. With a carburetor on each side, either two air cleaners or some form of pi e over or around the cylinder block would be required, but obviously undesirable. I have solved the difficulty by utilizing the charm her under the usual cover plate 9 as an air chamber. The air cleaner h screws into m3 of the cylinder and thence to the carburetor. This articular form of distribution has also a unctional value in connection with the'performance of the engine, as obviously the cylinder top gets more or less hot and the air is drawn into the carburetor in slightly tempered condition. This in cold Weather approximates more nearly a summer heat, which is a beneficial heat condition of the air as it is not unduly expanded, as is the case if the air is. unduly heated by some kind of a store along the exhaust uiai'iitold. Furtlxerinore, the circulatioi'i of air which is drawn in at considerable velocity around "the plug" has a beneficial effect in keeping the plugs cool. 7
This invention has been explained in connection with a straight-eight motor, but ohviously the number of cylinders so far as the broad principles of the invention are concerned, is immaterial.
What i claim is:
1.. In an internal combustion engine, a plurality of cylinders divided into a front set and rear set, the front set arranged for and provided with manifciding means for taking in the charge on one side and exhausting on the other side, and the rear set being arranged tor and provided. with maniltoiding means for exhausting; on the one side and taking in the charge on the other conversely to the front together with connections whereby the exhaust gases of one set of cylinders heats the incoming fuel mixture of the other set of cylinders onthc same side without being caused to pass to the opposite side of the cylinder on the same side, whereby the one set of cylinders lILlllllSllQS exhaust gases for heating the fuelcharge of the other set of cylinders'on the same side of the block.
3. In an internal combustion engine, the combination of an engine block provided with a plurality o1"? cylinders divided. and
having carburetor connections-on each side of the cylinders, a separate carburetor on each side of the cylinders jOlIlGCl with said connections, acover plate for the cylinder block, air intake conduits leading from the interior of the cover plate to the carburet ors, and an air cleaner surmounted on said cover plate for purifying the air that is admitted to the :interior of the cover plate and thence to both carburetors.
In testimony whereof I have allixcd my signature.
