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 carburetors that switch delivery of fuel to two different locations based upon the speed of the engine. The system uses an accumulator with piston ported reflected compression wave delivery of scavenged compressed air to deliver fuel at a wide open throttle position.

High speed carburetion system for compressed air assisted injection

An internal combustion engine having a cylinder with a piston movement area; a piston movably mounted in the cylinder; an ignition system connected to the cylinder; and a fuel delivery system connected to the cylinder. The fuel delivery system has a combined fuel and air injection port extending into the cylinder. The injection port has an end at the piston movement area with a top surface and a different shaped bottom. The bottom surface has an inwardly tapering shape to form a bottom portion of the end of the injection port with a generally semi-conical shape.
