Definitions

  • Supplemental air is permitted to enter the divergent section by means of holes in a plenum chamber (surrounding the bores) which receive the supplemental air from conduits.
  • a larger quantity of air is automatically controlled by a valve to enter the bores through the straight section during engine deceleration.
  • the invention relates to anti-pollution devices for internal combustion engines and more particularly to improved means for controlling the excess production of hydrocarbons in the fuel-air mixture of an internal combustion engine and more specifically to a plate member inserted between the carburetor and intake manifold of an internal combustion engine which is adapted to permit supplemental air to mix with the fuel-air mixture during all phases of engine operation.
  • the production of unmixed hydrocarbons in the fuel-air mixture is controlled by cyclonically mixing supplemental air with the fuel-air mixture leaving the carburetor.
  • a plate member interposed between the carburetor and the intake manifold has a shaped bore concentrically aligned with the respective bores of the inlet to the intake manifold and that of the carburetor exit, and has a plurality of conduits connecting atmospheric air to the bore through a plenum chamber surrounding the bore.
  • One of the conduits contains a vacuum valve which is slightly open when the engine is idling and is controlled so that it is wide open when the engine is decelerated.
  • the remaining conduits permit air to enter the plenum chamber and then to cyclonically enter the bore through a multiplicity of holes during acceleration as well as deceleration, thereby keeping the fuel-air mixture in continuous cyclonic motion, which substantially decreases the unmixed hydrocarbon content of the mixture.
  • a primary object of the present invention is to provide an internal combustion engine controlling device interposed between the carburetor and the intake 3,564,589 Patented Feb. 16, 1971 ice manifold for minimizing the production of hydrocarbons in the fuel-air mixture.
  • a further object of the invention is to provide an internal combustion engine controlling device which operates automatcally to admit supplemental air into the intake manifold in response to operating conditions of the engine.
  • Another object of the invention is to provide an internal combustion engine controlling device which admits supplemental air to the fuel-air mixture in a cyclonic motion to reduce the unmixed hydrocarbon content of the mixture.
  • Still another object of the present invention is to provide an anti-pollutant device which is of simple construction, strong, durable, inexpensive to manufacture and install.
  • FIG. 1 is a longitudinal sectional view of a portion of an internal combustion engine showing particularly the carburetor and intake manifold with the improved controlling device interposed between the two;
  • FIG. 4 is a longitudinal sectional view of the embodiment of FIG. 3.
  • FIG. 1 portions of an internal combustion engine with which the improved anti-pollution device is associated, said portions including an intake manifold 10 and a carburetor 11 having a conventional butterfly valve 12.
  • the anti-pollutant device designated generally by reference numeral 13 is adapted to be interposed between the carburetor 11 and the intake manifold 10.
  • the device 13 includes a pair of flat plate members 14 and 15 which are clamped together with a gasket 9 and screws (not shown) via openings 8 (FIG. 2).
  • conduits 24 and 26, which provide the supplemental air to the plenum chamber 40 are preferably positioned opposite the conduit 28; that is to say, on the same side of the carburetor wall against which the upper end of the butterfly valve 12 closes.
  • FIGS. 3 and 4 there is shown an alternate embodiment of the present invention wherein the vacuum valve 30 is connected with conduit 52 in the plate member 15a to a chamber 53 which is similar to the chamber 29 of FIGS. 1 and 2.
  • the conduit 52 and chamber 53 lie on a plane above the plane of conduits 24 and 26 and chamber 53 is connected to the bores 20 and 24 via channels (not shown) in the same manner as shown in FIG. 1.
  • the bores 20 and 22 are shaped to have a straight section, convergent section and divergent section as sections 33, 42, and 44 respectively of FIG. 2, such that supplemental air from valve 30 exits to the bores in the straight section and air from conduits 24 and 26 exits to the bores in the divergent section.
  • the plate 15a has a chamber 54 similar to chamber and it is similar in all other respects to plate 15.
  • the plate 15a is placed directly between the intake manifold and the carburetor with appropriate sealing means (gaskets, 0 rings, etc.) since there is no need for plate member 14.
  • the plate 15a should be positioned so that the vacuum valve 30, as in FIG. 1, is located on the carburetor wall against which the lower end of the butterfly valve 12 closes for the reasons mentioned above.
  • holes may be provided in the plate members 14, 15, or 15a such that they may be bolted to the intake manifold and carburetor flanges. It is, of course, understood that the channels or conduits 4 24, 26, 28, and 52 must be of a particular size for a particular engine. Therefore, if desired, the conduits may be made large enough to operate larger engines and be fitted with various diameter orifices for smaller engines.
  • the valve 30, as previously discussed, may be a simp e, conventional ball check valve.
  • this type of valve requires a finite time to open and thus the valve must be open when the engine is idling, otherwise the valve will not open wide enough to permit suflicient air to enter the bores during deceleration.
  • a valve of more sophisticated design which had a rapid time for opening (i.e. a solenoid-controlled valve operated by the throttle position) no bleeding of supplemental air to the bores through the valve at idle position would be required.
  • conduit means within said plate means for admitting supplemental air cyclonically to said bores during all phases of engine operation, said conduit means comprising,
  • a second channel means connecting one end of said second conduit to said bores for exiting a larger amount of supplemental air to said bores at engine deceleration than the amount of supplemental air exiting through said holes
  • valve means communicating with supplemental air at one end and having a second end connected to the second end of said second conduit
  • each of said bores of said plate means comprises a plurality of vertical sections comprising a cylindrical section, a convergent section, and a divergent section, and wherein said second conduit exits to said bores in said cylindrical section and said first conduit exits to said bores in said divergent section whereby supplemental air enters said first channel means and is conducted through said multiplicity of holes to exit through said divergent section during all phases of engine operation, thereby causing the fuel-air mixture to flow in a cyclonic pattern and to thoroughly mix the unmixed hydrocarbons with air and whereby a large additional amount of supplemental air is provided through said valve means to exit through said cylindrical section when said engine is decelerated.
  • each of said holes is angularly formed toward said intake manifold and non-radially.
  • each of said holes is tapered inwardly from said first conduit to said bores.
  • each of said holes is tapered inwardly from said first conduit to said bores.
