| (54) | Carburetion system |
| (57) A pressurized fuel carburetion system for internal combustion engines wherein varying
velocities and pressures are produced in the throat of the carburetor intermixing
fuel with the air passing therethrough in such a manner to create a plurality of cortices
containing air and fuel mixtures rotating about an axis substantially perpendicular
to the carburetor air flow. The carburetor includes a rotating baffle and fuel distributor
producing a restriction in the carburetor throat to cause high air flow velocities
and low pressures and the air subsequently expands in such a manner as to produce
low air flow velocities and higher pressures creating the desired vortices. The fuel
distributor is in the form of a rotating cup, and fuel supplied to the cup interior
is projected transverse to the air flow immediately prior to the region of vortex
generation. Fuel supply control means utilize a plurality of series related valves
employing engine manifold pressure and throttle position to control the rate of fuel
supply and idling and acceleration fuel requirements are controlled by appropriate
valves. |
