| Abstract: | Proper fuel supply system is crucial to realize the stratified scavenging for small type oftwo-stroke gasoline engine' A simple and effective diaphragm fuel injection system (DFI) isdeveloped, which utilizes the crankcase pressure that reflects the inlet flow rate to meter andinject fuel. As the DFI system has flexible fuel injection manner, such a system when combined with a special gas exchange system, can realize stratified scavenging process. |
