Abstract
This carburetor comprises plural cell carburetors which are controlled by a servo controller which controls the internal pressure of the carburetor to maintain the pressure constant by opening the air paths of needed number of the cell carburetors. Every one of the cell carburetors is either completely opened or almost closed; that is there is no intermediate opening between said two conditions except for special use. The ratios of air to fuel which is produced in each cell carburetor are predetermined for both the open and almost closed positions. Needed air and fuel are supplied by a combination of the cell carburetors which are selected from combinations of the cell carburetors to be selected for the working condition of the combustion engine.
Claims54
A carburetor comprising
- a plurality of cell carburetors,
- each cell carburetor having a conduit with an air inlet at one end, a fuel-air outlet at the other end, means for supplying fuel to the air flowing through the conduit, and airflow control means for providing only two sizes of air passageways through the conduit,
- manifold means for combining the fuel-air mixtures from said outlets, and
- controller means which keeps the internal pressure of said manifold means at a desired value, said controller means including means for controlling said pressure by operating said air-flow control means of the cells to provide the desired pressure.
A carburetor for an internal combustion engine comprising a multiplicity of cells, each of said cells comprising a conduit having an air inlet and a fuel-air mixture outlet, a fuel supply device for supplying fuel to each cell in relation to the air flow through the cell, air flow control means for separately controlling the air flow through some of the cells, in which the air flow means for each cell has a substantially closed position and only one open position, means for holding said air flow means of each cell in its substantially closed position but changing a progressively larger number of the air flow means of the cells to their open positions as the demand for the quantity of the fuel-air mixture at the output of said manifold increases, and a housing surrounding the fuel-air mixture outlets of the cells to combine the fuel-air mixtures of the conduits and provide a common outlet therefor.
A carburetor for an internal combustion engine comprising a multiplicity of cells, each of said cells comprising a conduit having an air inlet and a fuel-air mixture outlet, a fuel supply device for supplying fuel to each cell in relation to the air flow through the cell, air flow control means for separately controlling the air flow through some of the cells, in which the air flow control means for each cell has only two positions, one of which is an open position and the other of which is a substantially closed position, said air flow control means including means for controlling the air flow through the carburetor by varying the number of cells whose air flow control means is open, and a housing surrounding the fuel-air mixture outlets of the cells to combine the fuel-air mixtures of the conduits and provide a common outlet therefor.
A carburetor comprising
- a multiplicity of cell carburetors each characterized by a tubular element open at each of its two ends, one of said open ends comprising an air inlet and the other open end comprising a fuel-air outlet,
- fuel supply means for supplying fuel to said tubular elements intermediate their two ends,
- valve means, in each tubular element, downstream the fuel supply means for opening and closing the passageway through the tubular element, each said valve means having a substantially closed position and only one open position, and
- a manifold for combining the fuel-air outlets of said tubular elements.
A carburetor comprising
- a multiplicity of cell carburetors each characterized by a tubular element open at each of its two ends, one of said open ends comprising an air inlet and the other open end comprising a fuel-air outlet,
- fuel supply means for supplying fuel to said tubular elements intermediate their two ends,
- valve means, in each tubular element, downstream the fuel supply means for opening and closing the passageway through the tubular element, and
- a manifold for combining the fuel-air outlets of said tubular elements,
- each said valve means having a closed position and only one open position, and motor means for selectively actuating said valve means to either of its positions.
A carburetor comprising
- a multiplicity of cell carburetors each characterized by a tubular element open at each of its two ends, one of said open ends comprising an air inlet and the other open end comprising a fuel-air outlet,
- fueld supply means for supplying fuel to said tubular elements intermediate their two ends,
- separate valve means, for each of at least some of said tubular elements, for opening and closing the passageway through the tubular element, each said valve means being operable independently of the others and having only two different control positions, and
- a manifold for combining the fuel-air outlets of said tubular elements.
A carburetor comprising
- a multiplicity of cell carburetors each characterized by a tubular element open at each of its two ends, one of said open ends comprising an air inlet and the other open end comprising a fuel-air outlet,
- fuel supply means for supplying fuel to said tubular elements intermediate their two ends, and
- separate valve means, for each of at least some of said tubular elements, for opening and closing the passageway through the tubular element,
- each said valve means having only two operating positions, and motor means for selectively actuating each said valve means to either of its positions.
