UNITED STATES PATENT OFFICE 2,238,565 AUXILIARY AIR ADMISSION DEVICE Charles R. Morton, Mapiewood', N. J. Application February 2, 1939, Serial No. 254,218
3 Claims.
This invention relates to devices for producing more eflicient combustion of gasoline and other fuels in automobiles and other internal combus tion engines.
It is known that at certain speeds of an internal combustion engine, the suction is greater than at other speeds and gasoline is sucked into the cylinders faster than the intake of air, thus making the mixture too rich and the operation ineiiicient and uneconomical.
It is, therefore, an object of this invention to provide a device which can be applied to any type internal combustion engine, without material alteration, to increase the atomization and provide the necessary supply of air for emcient combustion. In accordance with the invention. the device is provided with a valve which can be readily adjusted to compensate for different degrees of suction in the engine.
A further object is the provision of a gasoline saving device having certain parts constructed with predetermined dimensions which are essentiel to the proper operation of the device.
A further object is the provision of a device for producing more efficient combustion in automotive engines, which device can be readily and conveniently applied to any type of automobile engine without material alteration.
These and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure, and in which:
Fig. l is an elevational view showing the device installed in an intake manifold 01' an internal combustion engine.
Fig. 2 is a plan view oi the device.
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.
Fig. 4 is a plan view partly in section.
Fig. 5 is a sectional view taken on line 5--5 oi Fig. 4.
Fig. 6 is an exploded view showing in detail elements of the device.
Fig. 7 is a perspective view of an element of the device.
Referring to the drawing, in Fig. 2, the device is shown to comprise a fiat main body i having a central opening of substantially the same diameter of an intake manifold. Curved vanes 2 proiect into the opening, the vanes being integral with the main body i. Attached to one side of the body l is a cylinder 5, which communicates with the central opening by means or a slot in in one side thereof to allow the entrance of air tegral with boss 9.
through the cylinder to the air passage. Slidably positioned in the cylinder 5 is a piston l, which rests on a compression spring 8, which encircles a boss 9 and rests on guide flange ill in- The underside of boss 8 is provided with a recess which engages the pointed end 01' an adjusting screw II, which is threaded in the lower end of cylinder 5, (see Fig. 4). By means of screw ii, the. tension of spring 8 can be adjusted to accommodate the valve for different suctions in diiierent automobiles. After the screw has been adjusted, it is maintained in the adjusted position by means of a lock nut ii.
The upper portion of cylinder 5 has a pin it passing therethrough, which limits the upward movement or piston l. The position of the pin I3 is important. It has been found that pin I! should be 1% inches from the bottom of the cylinder, and the air hole or opening 8 should be inch from the bottom of the cylinder. The opening 6 or air hole should be .101 inch; and the inside diameter of the cylinder 5 should be .375 inch plus or minus .0002 inch, with the piston having a diameter of .373 inch plus or minus .0002 inch. The spring 8 preferably has'a diameter of .335 inch, with 6 turns in .750 inch of .024 inch diameter music wire.
It has been further determined that effective results require the vanes 2 to be inclined to the horizontal at an angle of from 44 to 46.
The above dimensions are essential to the proper operation of the device herein described; and it has been discovered that efllcient operation can not be obtained with other dimensions.
From the above description, it will be seen that there has been provided a simple and effective gas saving device which is adapted for use on all types of automobiles. The adjusting screw enables the device to be readily and efiiciently adjusted for use on diilerent types of engines. De-
vices of this. type, when constructed with the above mentioned dimensions have been found to provide 20% more mileage per gallon of gasoline.
A further feature of the device is the forming of the cylinder and main body integral with the slot from the cylinder to the central opening. This greatly decreases the cost of manufacture and enable the production of a sturdy device'which will last indefinitely. The vanes 2 serve to atomize the gasoline vapor as the globules of gasoline pass over the edges of the vanes; and complete combustion is insured by the functioning of the air valve to provide the necessaryquantity of air a at, various speeds and maintain the correct air;
fuel ratio.
The device herein described can be readily and inexpensively cast and assembled, and the device is universally applicable to all engines, as it can be simply. adjusted for the differences in suction in different engines.
The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention,'of which proper proportions of air and fuel in an internal combustion engine, comprising a plate having a centrally located opening adapted to be inserted in the intake manifold of an engine, a cylinder integral with said plate, said plate having a slot between the opening and the cylinder, plates covering both sides of the slot to provide an airtight passage between the cylinder and opening,
said cylinder having an internal diameter of .375
inch plus or minus .0002 inch, a piston slid-ably mounted in the cylinder, said piston having'a diameter of .373 inch plus or minus .0002 inch, a boss positioned in one end of the cylinder and having a guide flange, a compression spring engaging the piston to urge the latter in one direction, said spring encircling the boss and resting on said opening and the cylinder,
flange, means to limit the movement of the piston in one direction, said cylinder having an opening of .101 inch diameter for the entrance of air, a screw threaded in one end of the cylinder and bearing against said boss to adjust the tension of the spring, and a lock nut for holding the screw in adjusted positions.
2. In an air and fuel mixing device for internal combustion engines, a plate having a centrally located opening adapted to be inserted in the intaire manifold of an engine, a cylinder integral with the plate and having an internal diameter of .375 inch plus or minus .0002 inch, an airtight passage for air from the cylinder to the opening,
said cylinder having an opening of .101 inch diameter for the entrance of air, a piston having a diameter of .375 inch plus or minus .0002 inch slidably mounted in the cylinder and adapted to cover the opening in the cylinder at certain speeds of the engine, a compression spring positioned in the cylinder and bearing against the piston to normally force the piston to a position whereby said opening inthe cylinder is uncovered, said spring a diameter of .335 inch, and being formed of 6 turnsgin .750 inch from music wire having a diameter of .024 inch, and means to adjust the tension of the spring.
3. A device for providing the proper proportions of air and fuel in an internal combustion engine, comprising a plate having a centrally located opening adapted to be inserted in the intake manifold of an engine, a cylinder integral with said plate, said plate having a slot between the a piston slidably mounted in the cylinder, a boss positioned in one end of the cylinder and having a guide flange, a
, compression spring engaging the piston and urging the piston in one direction, said spring encircling the boss and resting on said flange, means to limit'the movement of the piston in one direction, said cylinder having an opening for the entrance of air, a screw threaded in one end of the cylinder and bearing againstthe boss to adjust the tension of the spring, and a lock nut for holding the screw in adjusted positions.
