INTERNAL 'COMBUSTION ENGINE Filed July 18, 1924 2 Sheets-Sheet 2 Patented Dec. 1,Y 1931 PATENT OFFICE MARC BIRKIGT, F BOIS COLOMBES, FRANCE INTERNAL COMBUSTION ENGINE Application filed July 18, 1924, Serial No. 726,873, and in Belgium July 18, 1923.
This invention relates to improvements in internal-combustion engines particularly with regard to their carburettors.
The invention has for its object to render the said engine more adequate to answer praetical requirements.
The invention comprises a Carburettor or carburettors which has or have a relatively large surface of contact with the side of the engine, the said Carburettor or carburettors being heated by conductivity through the said surface.
The invention further comprises certain other arrangements hereinafter described and claimed.
Reference may now be had to the following description andaccompanying drawings, by way of example, in
Figures l and 2 of which an engine is illustrated in side elevation and in partial end sectional elevation along the line 22 of Figure 1, respectively,
The internal-combustion engine shown is an aero engine with two rows of siX cylinders, and the carburettors, one for each two cylinders, are disposed so that they are heated by contact with the engine.
The carburettors a of the engine may be of any suitable form and are each shown as having' an air intake L2 depending therefrom. A delivery pipe al extends from the upper portion. of each Carburettor, each Carburettor together with its delivery pipe being madeso that it comprises metal plate I) of relatively large area and following the shape of the water jacket of the engine, the said jacket being flat, as shown in the drawings.
The carburettors are secured to the engine by applying the plates o of each Carburettor against the wall c of the water-jacket of the engine, the said carburettors being secured in position by any suitable means, for example With the aid of bolts CZ. The regulating members of some or all of the carburettors belonging to one row of cylinders are connected together by the same rod e, the said rod being provided with devices for varying the setting of each of the said members relatively to the others.
It will be seen from the foregoing description that a portion of the heat derived from the water acleet of the en gine is transmitted directly to the various metal plates and is thus used for heating the carburettors. In aero engines of this type which must operate at great altitudes this is a great advantage since the low temperatures so encountered frequently cause the condensation of moisture in the form of ice on the carbureters exterior parts and chill the interior portions so as to prevent their proper functioning.
The exchange of heat between the engine and the carburettors may be intensified by means of ribs or tins 7" between the plates L and the carburettors a.
Obviously, the invention is not limited to the construction more particularly set forth but comprises all variants within the scope of the claims.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, declare that what l claim is l. The combination with the cylinder-block of an internal combustion engine of an assembly comprisingl` a plate and a carbureter mounted thereon, said plate being adapted to be mounted in heat conductive relation with said cylinder-block, said earbureter being positioned so that a portion thereof lies within the bounds of the plate whereby heat is transferred from the plate to the Carburettor.
2. ln an internal combustion engine provided with a plurality of cylinders, a plurality of assemblies each comprising a plate adapted to be attached in heat conductive relation to a cylinder and a carbureter niouned on each plate, each of said carbureters being positioned so that a portion thereof lies within the bounds of one of the plates and in heat conducting relation thereto,-and means for simultaneously coi'itrolling the output of said carbureters.
ln testimony whereof I have hereunto set my hand.
MARC BIRKIGT.
