摘要： A carburetor including a frame having a first air/fuel channel and a second air channel; and a throttle valve assembly connected to the frame and having two valve sections. Each valve section is located in a respective one of the channels. A second one of the valve sections has an air bleed hole therethrough. The second valve section is movable relative to the frame from a first idle position to a second intermediate closed position and then to a third open position at a wide open throttle (WOT). The air bleed hole allows flow through the second channel at the first idle position, but does not allow flow through the second channel when the second valve section is at the second intermediate closed position.

摘要： A two cycle internal combustion engine cylinder having a piston chamber. The cylinder includes transfer ports; and an exhaust port divided into at least two sections. A first one of the sections has an aperture at the piston chamber with a top surface located closer to a top of the piston chamber than a top surface of an aperture of a second one of the sections at the piston chamber. The first section has a cross-sectional area which is smaller than a cross-sectional area of the second section. The aperture into the first section is located further away from the transfer ports than the aperture into the second section.

摘要： A two-stroke internal combustion engine includes at least one gaseous communication charge passage between a crankcase chamber and a combustion chamber of the engine and a piston to open and close the top end of the passage and a rotary valve to open and close the lower end of the transfer passage. The air inlet port to the transfer passage for stratified scavenging is opened and closed by the crank-web that has passages and cutouts. The rotary valve replaces the one-way reed valve used in stratified scavenged and charged two-stroke engines. The air passes from the lower end of transfer passage to the top end and into the crankcase through the piston passage, alternatively air may also pass through the adjacent transfer passage directly or through a passage in the piston into the crankcase. A two-stroke engine also consists of a charge injection system controlled by the crank web eliminating the one-way valve.
