In order to improve the drawbacks of current schnürle-type two-stroke gasoline engine, a reverse uniflow-type two-stroke direct injection engine was designed and developed. The scavenging port and piston geometry combined with a direct injection system were designed to realize both stratified charge combustion in light to medium load and higher power output in high load range. In-cylinder gas motion and spray behavior were analyzed and optimized by numerical simulation. The experimental result shows high BMEP in WOT operation achieved by a high delivery ratio, high trapping efficiency and good scavenging. In light to medium load a stable combustion was achieved by good stratified combustion utilizing a spray and wall guided mixture preparation.
