MANIFOLD FOB INTERNAL-COWIBUSTXON ENGINES.
Specification of Letters Patent. Pmtfientetl FIGV. 15,
Application filed November 15, 1919. Serial No. 338,167.
To all whom it may concern:
be it known that 1, ANDREW BAoHLn, a citizen of the United States of America, rcsiding at Detroit, in the county of Wayne and State of Michigan, have invented cer tain new and useful improvements in Manifolds for lnternal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to manifolds for internal combustion engines of that type in which the cross-sectional area of the manifold is varied to produce a throttling effect and to maintain the velocity of the gases. 'lhe present invention comprises the novel construction of the means for varying the cross-section of the manifold, and further in the combination of the inlet and exhaust manifolds in one structure as hereinafter set forth.
in the drawings:
Figure 1 is a sectional side elevation of a portion of the manifold constructed in accordance with my invention;
Figs. 2, 3 and 4 are crosssections, respectively, on lines 22, 33 and 4. l of Fig. 1.
in the usual construction of inlet mani folds for internal combustion engines, the cross-sectional area of the conduit is fixed and the volume of gas passing therethrough is controlled by a throttle. This has the disadvantage of greatly decreasing the velocity of the gases in their passage through the manifolds when the throttle is partially closed. On the other hand, by varying the cross-sectional area of the intake uniformly throughout its extent, the volume of gas may be controlled without greatly reducing the velocity.
With the present invention the variation in the area of the inlet is accomplished by a simple easily manipulated mechanical construction. In detail, A is a manifold, preferably embodying one integral construction, an exhaust portion B and an inlet portion C. The inlet portion is in the form of a straight cylinder D standing adjacent to the several ports E leading into the engine cylinders and also adjacent to the common inlet ort F connecting with the oarbureter.
Within the cylinder D is placed a segmental abutment G which is secured by suitable means such as the screws H passing through apertured bosses I at one side of the cylinder. J is a rock shaft extending completely through the cylinder coaxially therewith, and K is a segmental wing seends of the cylinder. Uneend of the shaft is connected with the lever arm *0 by means of which the shaft maybe rotated in various positions of adjustment.
With the construction as described, in operation, when the shaft is in a position, shown in Fig. 2, the win K is in close proximity to the abutment (I so as to produce a passage of restricted cross sectional area throughout the manifold. This passage is, however, in communication with both the inlet port F from the carbureter and the several ports E leading into the engine cylinders so that the gas will pass at uniform velocity but in restricted volume to the cylinders. To increase the power the shaft J is rocked through the medium of the arm 0 swinging the wing K to enlarge the passage for the gas. in this way the manifold may be enlarged in cross-sectional area to its maximum capacity where the wing comes in contact with the abutment G.
The inlet manifold being integral with the exhaust manifold, the outer wall of the inlet manifold will be heated which will facilitate the complete vaporization of the liquid fuel. Over-heating is avoided chiefly by reason of the fact that the gas passes through the manifold at high velocity, but if any of the liquid is deposited on the walls, it will quickly be converted into vapor.
What I claim as my invention is:
1. An inlet manifold for internal combustion engines, comprising a cylindrical conduit, a stationary partition therein, and a member rotatably adjustable with respect to said stationary partition for enlarging and diminishing the cross-sectional area of said conduit, the axis of rotation of said member extending longitudinally of said cylindrical conduit.
2. An inlet manifold for internal combustion engines, comprising a cylindrical conduit, a shaft extending axially through said conduit, a stationary partition extending from the wall of said conduit to said shaft, and a wing secured to said shaft and extending to the. periphery of said conduit, said shaft and wing being rotatably adjustable to-enlarge or diminish the cross-sectional area of the conduit.
ports.
3. An inlet manifold for internal combustlon engines, comprislng a cylindrical conduit, provided With an inlet port and a plurality of ports connected laterally therewith and to the respective cylinders of the engine, a rotative shaft extending axially shaft, and means for adjusting said shaft and wlng relatlveto sa1d stationary part1- tion to enlarge or diminish the cross-sectional area of the conduit which is in communicatlon with said lnlet and cylinder 4:. A manifold for internal combustion englnes having an exhaust passage therein and a cylindrical inlet'passage, the latter being provided with an inlet port and. a plurality of cylinder-connecting ports, a rotative shaft extending axially through said cylinderical 3 conduit, a Wing secured to said shaft and extending to the; periphery of the conduit, a partition extending from said conduit to saidfshaft, and means for rotatively adjust ing the shaft and wing to enlarge or diminish-thecross-sectional area of the conduit which is in communication with said ports.
5. A manifold for internal combustion engines, comprising a cylindrical conduit having open ends, caps for closing said ends, a shaft extending axially through said conduit and journaled in said caps, a segmental wing secured to said shaft and extending to the; cylinder Wall of the conduit, a segmental stationary partition securedto the wall of the conduit and extending. through said shaft, and means for rotatively adjusting said shaft to enlarge or diminishthe crosssectional area of said conduit.
