FUEL ECONOMIZER FOR INTERNAL-COMBUSTION ENGINES.
Applicat )n filed September-22, 1922. rSerial No. 589,915.
, To all whom it may concern:
Be it known that l, MATHEW LorsAcK, a citizen of the United States, residing at Sebeka, in the county of lVadena and State of Minnesota, have invented certain new and useful Improvements in Fuel Economizers for internal-Combustion Engines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an internal coinbustion en'ine and particularly to such an engine of tie automobile type. In such engines, there is considerable leakage ofthe 'uel mixture or gas past the pistons in the cylinders, which gas passes into the engine or crank casing. A considerable volume of combustible gas is therefore contained in the crank casing:
It is an object of this invention to provide means on the engine forlutilizing this gas contained in the crank or engine casing.
lt is a further object of the invention to accomplish this result by providing a conduit connected to the crank casing and also connected to the fuel intake conduit of the engine.
t is more specifically an object of the invention to provide such a conduit, together with a screening means for preventing solid natter being drawn thereinto from the crank casing and to provide a valve in the air intake conduit beyond the connection of the conduit from the crank casing thereto.
'These and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings in which the single view shows a side elevation (f an internal combustion engine with the invention applied thereto.
Referring to the drawing, an `automobile engine of the well known Ford type is more or less diagralnmatically represented and which illustrates the intake manifold l. the carburetor 2:, the air intake conduit 3, the adjusting means i for the carburetcr and the engine and crank casing 5. The carbureter has the usual throttle valve arm 3 and the choke valve arm 7. In the type oit engine illustrated, there is usually'a pipe, .Meli as shown at 8, connected to the crank casing and having air passages thereinto to equalize the pressure in the crank casing with that of the atmosphere, which pipe is coininonly known as the breather pipe. ln the embodiment of the invention illustrated, a conduit 9 is provided connected at one end 60 to the pipe 8 and ythus to the crank casing and connected at its other end to the air intake conduit 3. A conduit 9 is prbvided with a iexible section l0 so that the saine may be somewhat bent to pass operating` means 4. The pipe 15 thereon of substantially7 shape about the lower edge of passes into said pipe. A screen l1 is placed in the pipe 8 below the conduit 9 and a wing 7 0 or diaphragm valve 12 is provided in the conduit 3 above the conduit l0 having the operating handle 13 and being -rictionally held in adjusted position by a spring 111.
ln operation, air will he drawn through I5 the conduit 3, as usual, and through the carbureter 2 into the intake manifold. The gas contained in the crank casing 5 will also be drawn into the carburetef.' through the conduit 9, as indicated by the arrows and BU some air will pass into the pipe 8 through the cap 15, as indicated by the arrows. The amount o'suction throu h the conduit 9 can be varied by adjusting the valve l2 and any solid or other objectionable matter will he' et prevented from passing into the conduit 9 y the screen ll. The combustible gases passing into the crank casing 5 will thus he utilized and will be carried with the heated air into the carbureter 2 where they will a0 be mixed with the usual fuel mixture. The air and combustible gas yin the crank casing is also churned with theoil therein and oecomes somewhat emulsiiied andthe mixing of this air with l"the flnel assists in efficiently e5 lubrica-tingthe valves and cylinder. The amount of oil thus carried, however, is not sufficient to cause any objectionable results in the cylinder.
The applicant has demonstrated the in- 10c vention in actual practice and nds that considerable more mileage can be obtained from a given quantity of fuel by the use ci the invention. When the saine is used the carbureter can be adjusted to feed 'much less 1er fuel than when the 'invention is not used.
While in the embodiment of the inven tion illustrated the conduit 9 connects the crank casing with the intake pipe 3 beyond the carbureter, it is within the scope of the lic present invention to connect said conduit at any point in the intake pipe or manifold.
8 has a cap sernrspherical which the air around the 6E From the above description it is seen niiet applicantlias provided e simple and efficient clevie for eeonomizing fuel. The parte of the device are extremely Simple and een be readily ,and inexpensively apfpled to Stendarl automobile engines with no appreciable' change in the parts thereof.
