Abstract
A device for mixing and atomizing the fuel-air flow which is positioned between the carburetor and the intake of an internal combustion engine. The device comprises a swirl chamber which creates turbulence in the fuel-air flow by turning a portion of the flow upstream into the downward flow going to the engine intake and has a trough which collects liquid fuel droplets which have landed on the swirl chamber wall. The liquid fuel collected in the trough is vaporized by the heat of the engine and then re-enters the fuel-air flow.
Claims9
A swirl chamber between a carburetor barrel and a combustion chamber in an internal combustion engine, said swirl chamber having a substantially cardioid shape in cross section and being substantially symmetrical about its axis, said swirl chamber comprising:
- an entrance throat at the top of said swirl chamber nearest to the carburetor;
- an exhaust throat at the bottom of said swirl chamber nearest to the combustion chamber, said exhaust throat having a smaller underlying perimeter than said entrance throat and being disposed directly beneath said entrance throat, and being in direct fluid communication with said entrance throat;
- a lip at the bottom of said swirl chamber extending radially outwardly from the perimeter of said exhaust throat formed to direct vapor flow upwards toward said entrance throat;
- and
- an annular trough extending radially outwardly from the lip.
A swirling device for use in an internal combustion engine having an upper portion to be disposed nearest to the carburetor of the engine and a lower portion to be disposed nearest to the combustion chamber of the engine, comprising:
- an entrance throat in the upper portion of the swirling device;
- an exhaust throat in the lower portion of the swirling device directly and completely beneath said entrance throat and having a smaller perimeter than said entrance throat, in direct fluid communication with said entrance throat;
- an intermediate portion disposed between said entrance and exhaust throats to fluidly connect said entrance and exhaust throats, having a vertical cross-sectional shape which is substantially cardioidal and which is substantially symmetrical about its vertical axis;
- a lip at the bottom of said intermediate portion, extending radially outwardly from the perimeter of said exhaust throat, formed to direct vapor flow upwards toward said entrance throat;
- and
- an annular trough extending radially outwardly from said lip.
A swirling device for use in an internal combustion engine, having an upper portion to be located nearest the carburetor of said engine and a lower portion to be located nearest the combustion chamber of said engine, comprising:
- an entrance throat in the upper portion of said swirling device;
- an exhaust throat in the lower portion of said swirling device directly and completely beneath said entrance throat and having a smaller perimeter than said entrance throat, in direct fluid communication with said entrance throat;
- a smooth-surfaced intermediate portion between said entrance and exhaust throats to fluidly connect said entrance and exhaust throats, having a vertical cross-sectional shape substantially cardioidal and substantially symmetrical about its vertical axis;
- a lip at the bottom of said intermediate portion, extending radially outwardly from the perimeter of said exhaust throat, formed to direct vapor flow upwards toward said entrance throat;
- and
- an annular trough extending radially outwardly from said lip.
