Abstract
An internal combustion engine having a crankcase, a cylinder connected to the crankcase, a compressed air assisted fuel injection system connected between the crankcase and the cylinder, and a reciprocating piston head located in the cylinder. The improvement comprises a fuel delivery system having two carburetor sections with two interconnected rotatable shafts.
Claims16
In an internal combustion engine having a crankcase, a cylinder connected to the crankcase, a compressed air assisted fuel injection system connected between the crankcase and the cylinder, and a reciprocating piston head located in the cylinder, wherein the improvement comprises:
- a fuel delivery system having two carburetor sections with two interconnected rotatable shafts, wherein a first one of the carburetor sections has an outlet in communication with the crankcase for delivering air to the crankcase, and wherein a second one of the carburetor sections has an outlet in communication with the cylinder for delivering a fuel and air mixture into the cylinder without passing the fuel and air mixture through the crankcase.
An internal combustion engine carburetion system comprising:
- a frame having two air flow channels;
- two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels;
- and
- a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies
- wherein the two throttle shaft assemblies each have a shaft which are angled at an acute angle relative to each other.

A method of assembling a carburetor for an internal combustion engine comprising steps of:
- providing a frame having two air flow channels through the frame, the frame having a fuel conduit system for supplying fuel to the two air flow channels;
- connecting two control shaft assemblies to the frame, a first one of the shaft assemblies extending into a first one of the air flow channels;
- and
- operably connecting the two control shaft assemblies to each other to coordinate movement of a second one of the shaft assemblies at least partially relative to movement of the first shaft assembly,
- wherein movement of the second shaft assembly at least partially controls supply of fuel delivery to a second one of the air flow channels, and wherein movement of the first shaft assembly from a first idle position to a second wide open throttle position has a coordinated movement of the second shaft assembly for a majority of angular rotation of the first and second shaft assemblies from a first small or no fuel supply delivery position into the second air flow channel to a second relatively larger fuel supply delivery position with fuel delivery from the fuel conduit system being switched, at least partially, from the first air flow channel to the second air flow channel by changes in vacuum pull in the first and second air flow channels when the two control shafts are moved between their respective first and second positions.
