The dynamic characteristics and the scavenging process of FPLG were analyzed based on this simulation architecture and the efTect of key structu陀 parameters of the scavenging system including port height and port angle on 创avenging quality was studied as well. The results show that. large height of scavenging and exhaust ports, tangential inclination of main scavenging 阳rt at 650 and axial inclination of sub scavenging port at 500 can increase scavenging efficiency; small height of scavenging and exhaust po邸， small tangential inclination of main scavenging port and large ax ial inclination of sub scavenging port can enhanee the turbulent kinetic energy in cyl inder .
