HIGH SPEED CARBURETION SYSTEM FOR COMPRESSED AIR ASSISTED INJECTION

摘要

An internal combustion engine (10) having a crankcase (18), a cylinder (12) connected to the crankcase (18), a compressed air assisted fuel injection system connected between the crankcase (18) and the cylinder (12), and a reciprocating piston head (14) located in the cylinder (12). The improvement comprises a fuel delivery system (22) having two carburetors (19, 20) that switch delivery of fuel to two different locations based upon the speed of t he engine (10). The system uses an accumulator (34) with piston ported reflecte d compression wave delivery of scavenged compressed air to deliver fuel at a wide open throttle position.
