Dec. l15, 1936. Af M. BALOGH FUEL MIXER Filed oep., 2, 1954 y BY m ATTORNEY Patented Dec. 15, 1936 FUEL MIXER Andrew M. Balogh, Chicago, lll., assigner of onehalf to Earl L. Hoyles, Chicago, Ill.
Application October 2, 1934, Serial No. 746,569
14 Claims. (01.'123-119) My invention relates to internal combustion engines, and has among its objects and advantages the provision of improved means for reclaiming fuel passing to the crank case by reason of leakage between the pistons and their cylinders. The invention also embodies means whereby highly explosive fuel vapors are mixed with thek fuel delivered to the engine.
In the accompanying drawing:
Fig. lis a side elevation of an engine embodying the invention;
Fig. 2 is a sectional view illustrating a valve control for the device;
Fig. 3 is an enlarged sectional view of the invention;
Fig. 4 is a sectional view along the line 4-4 of Fig. 3; and
Fig. 5 is a sectional View along the line 5-5 of Fig. 4.
In the embodiment selected to illustrate my invention, I make use of an internal combustion engine l0 provided with the usual intake manifold l2 and a breather pipe I4 for the crank case I6. My invention co-mprises a tank structure I8 mounted upon the wall 26 through the medium of a bracket 22.
The tank structure comprises an outer drum 24 having communication with the breather pipe i4 through the medium of a conduit 26. In Fig. 3, I illustrate the drum 24 as being provided with a tapered bottom 28 having a valve plug 36 connected with the conduit 26. The valve plug is provided with a valve plate 32 arranged to permit vapors from the crank case to enter the drum. The disc comprising the valve 32 is freely housed between. two wire loops 34 fastened to the valve plug 38.
'Ihe opposite endof the drum 24 comprises a top 36 having a flat part 40 and a ange 42 pressed into the open end of the drum 24. I mount a valve head 44 upon the flat part 40 through the medium of bolts 46. This valve head is provided with a bore 48 Within which I position a rotary valve plug 50. I provide the plug y56 with a transverse opening 52 arranged to communicate with a bore 54 in the head 44. In Fig. 3, I illustrate the fiat part 40 as being provided with an opening 58 in alignment with the bore 54 so that communication is established with the interior of the drum 24.
Referring to Fig. 4, the head 44 is provided with a bore 66communicating with the bore 48 and having an enlarged threaded opening 62 for the reception of a connecting element 64 having a threaded connection with a conduit 66 cornmunicating with the fuel conduit 68 connecting the carburetor 10 with the manifold I2. Thus, it will be seen that the interior of the drum 24 may be arranged in communication with the manifold when the valve 58 is adjusted according to Figs. 3, 4, and 5.
The structure thus far described provides means whereby the fuel passing to the crank case i6 by reason of leakage between the pistons and the cylinder walls may be reclaimed. This fuel, together with other hot vapors, usually passes to the atmosphere through the medium of the breather pipe I4. I provide a control for the material flowing through the conduit 66. This control comprises a butterfly valve 12 arranged within the conduit 66 for rotation about the axis 14 through the medium of an arm 16.
The free end of the arm 16 is connected with the arm 18 associated with the conventional throttle valve 86 through the medium of a link B2. Adjustment of the throttle valve 8|] is made in the usual way through the medium of the foot operated rod 84. In the idling position of the throttle valve 80, thevalve 12 isclosed. I prefer to arrange the link 82 so that the throttle valve 86 will be open partly before the valve 12 is moved. To this end, the free end of the arm 16 is provided with an opening for loosely receiving the headed end 86 of the link 82. I mount a spring 88 upon the link 82 and position one end in abutting relation with a fixed collar 9|] and the opposite end in abutment with the arm 16.
It will be noted that the head of the end 86 is positioned in spaced relation with the free end of the arm 16 so that the shifting of the arm 18 associated with the throttle valve 88 does not move the arm 16 until the throttle valve has been opened partly. The valve 12 provides an effective closure during the throttle adjustment of the valve 80 so that no material can enter the conduit 68 during the throttle adjustment. To secure eicient operation of the engine, I find it advantageous to defer the opening of the valve 12 until the throttle valve has been opened partly. In other respects the two valves are adjusted simultaneously through the medium of the foot operated apparatus.
Within the outer drum 24 I mount an inner drum 92 secured in place by brackets 94 comprising integral reaches of the bottom 28 and the top 36. The bottom 28 is provided with a flange 86 of the same type as the flange 42. The upper brackets 94 may be welded to the inner drum 92, while the ends of the cylindrical part of the drum 94 may be Welded to the anges 42 and 96. However, I prefer to make the top 36 removable which may be accomplished by providing a snug liquidtight relation between the iiange 42 and the drum 24.
I place a screen 98 over the open end of the inner drum 92 and fill the drum with a sponge |00. The drum is provided with a supply of highly volatile fuel. I have found a mixture made up of the following ingredients and proportions to provide satisfactory results:
Ounces Ether 1 Gasoline (high test) 35 Machine oil 4 This fuel is supplied to the inner drum 92 through a tube |02 which has its lower end positioned close to the bottom of the inner drum. The bottom of the tube is closed, slightly enlarged, and slotted at |04 to provide inlet openings for the fuel mixture. The other end of the tube is firmly secured within a bore |05 in the head 44 and may be placed in communication with the bore 48 when the valve plug 50 is moved longitudinally to the dotted line position of Fig. 3.
In the dotted line position of the valve, the fuel mixture may be poured through the opening |06 closed by the cap |08. Normally the valve 50 is held in the position of Fig. 2 by a coil spring I I0 having one end abutting against the enlarged part of the valve and its other end abutting the end of the screw plug ||2 fastened within the threaded part of the bore 48.
To hold the valve 50 in various adjusted positions, I provide a spring pressed ball I6 arranged to lie within recesses |I8, |20, and |22 in the plug. This ball yields upon the application of a predetermined force upon the Valve plug to permit rotation and longitudinal shifting.
In operation, the valve 50 is adjusted to the position of Fig. 3 at which time the vapors originating in the crank case of the engine are sucked into the conduit 68 and delivered to the engine with the fuel from the carburetor. During such normal operation, vapors generated in the inner drum 92 pass through the screen 98 and commingle with the vapors coming from the crank case. The addition of the vapors from the inner drum S2 to the fuel delivered to the engine provides a highly efficient fuel mixture and results in improved engine efficiency.
Over a long period of use some of the oil in the vapors passing through the device from the crank case may condense and settle in the inner drum 92. Any large accumulation of such oil may be removed by rotating the valve 50 to establish communication with the tube |02, through the bores |24 and |26, while the engine is operating, so that the accumulated oil will be sucked out of the container.
In Fig. 5, I illustrate a flap valve |28 movably connected with a tubular support |30 arranged within the element 64. The valve is arranged to permit free movement of vapors to the intake manifold, but provides an effective closure in the event of back pressure, such as back firing.
Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
