ADOLF INDLEKOFER, 0F BASEL, SWITZERLAND.

INTERNAL-COMBUSTION ENGINE.

Application -ledngu'st 3, 1923. Serial No. 655,584.

To all whom it may concern: d

Be it known that I, AnoLF INDLEKOFER, a German citizen, residing at Basel, Switzerland, have invented new yand useful Improvements Relating to Internal-Combustion Engines, of which the following is a full, clear, and exactspeci'ication.y

The invention relates'to an" apparatus for effecting econom in fuel consumption in thev operation o internal Combustion engines. l

According to the present invention small particles of the oil contained in the crank case of an internal combustion engine are transformed by means of heated air into a highly gaseous condition. The oil vapour -thus formed is withdrawn from the crank Casing under the suction action of 'the piston of the motor and i ited with, the mixture'- of 'fuel and air delivered from' thel Carburettor, thereby effecting a considerable saving in the fuel consumption.

The apparatus provided for this urpose, comprises an air inlet Casin or ousing` heated b the exhaust gases o the engine', a conduit om this casing to the crank casing ipe leading from the crank Case to the exp osion chamber of the motor preferably provided with an oil extracting and collecting device.

In the accompanying drawings:

Figure 1 is a view in-sectional elevation of a simple form of apparatus embodying the invention;

' Figure 2 being a detail view of a portion of the apparatus shown in Figure 1, illustratin a modification. I

Re erringnow' to the drawings z the exhaust pipe A1 4of the motor cylinder A is shown surrounded by an open ended casing B in communication with the atmosphere at both ends. 'A pipe C connects the interior of this Casing with the crank casing D of the motor in which a certain quantity of lubricating oil is always resent. The crank case D is alsoconnecte by 'a pipe e with an oil extracting and collecting device e1, which constitutes 1n the pipe e a sudden enlargement. for removing the heavy particles of oil. A pipe ez leads from the oil extracting device e1 toa regulatin device f the latter of which is connected a pipe to a valve casin a mounted upon t e motor cylinder. The interior of the valve Casin a is in communication with the Combustion space past a valve a thelatter of which is arrangedto open automatically upon the suction stroke of the motor piston E but otherwise to be held on its seat formed in the wall of the combustion cham er. In the combustion chamber A2 a sparking plug d -is provided and to this chamber past a valve gaseous Condition with `very nely divided particles in suspension. The heated air flowing through the pipe C from. the Casing B the latter of which as stated above is traversed by the exhaust pipe A1 strikes this gaseous mixture which at the same time `mingles with the hot gases which may pass during the com ression stroke between the piston E and. t e wall of the cylinder A. Under the heating action, the particles of oil are transformed into a highly gaseous or vapourous condition. -During the suction stroke of the piston E the valve c in the valve casing a will be opened so that the oil vapour formed ,in the crank casing D is drawn through the pipe Connection e, e1, e?. As this vapourous mixture passes through the oil extracting device e1, the heavier particles of oil therein are separated from the body'of the mixture by reason of their reduced speed, and collecting in the device may be drawn oii' from time to time. The pure oil vapour Continues lfits course and passes through thel pipe` .Connection e2 extending from-the oil extracting device e1 to the regulatin device and thence to the explosion cham er A2 o the cylinder A past the valve c, where it is mixed with the fuel admitted through the vvalve s and is exploded in the usual way. Thereby, not only is economy in fuel eiected but the action of the explosion on the piston i E of the mixture of fuel and air produced by the Carburettor and L fiowing through lthe pipe r is correspondingly increased.

In the arrangement shown inFig1ire 1 the valve casing a is shown rovided with a receptacle formed like a lu ricating device and provided with a controlling cock h through which etrol may be supplied for cleaning the4 va ve guide,rand benzine for starting the motor.v

In the modification illustratedm Figure 2, the pipe connection e is connected to the i oil extracting device e1 as in the case already described but the pipe e2 opens into the pipe r leading from the carburettor to the eX- plosion chamber of the motor. In this construction the valve casing a and the valve c are rendered unnecessary. As the oil vapour assists the action of the lexplosion an economy is achieved regardless of the character of the spirit employed which may be petrol or other spirit.

What I claim is: l

In internal combustionengines, a motor cylinder with means for admission of combustible ....vf a crank casewith an oil bath an air suply casing connected to said t 1|: t ce form 'tting air thereto in intimiams? mate contact with oil, means for heating air in said air supply casing, an air admission device near the combustion chamber of the motor cylinder, a connecting pipe between said crank case and air admission device to admit oil impregnated air therefrom to said combustion chamber and a regulating device Within said connecting pipe to regulate the flow of fluid therethrough, substantially as and for the purpose described.

In Witness whereof I have hereunto Signed my name this 18th day of July, 1923, in the presence of two subscribing witnesses.

ADOLF INDLEKOFER.
