The invention provides a continuously improved and perfected two-stroke gasoline engine with the functions of auxiliarily simulating the aerodynamic analysis and adding double-filter-screen scavenging. According to the two-stroke gasoline engine, a double-screen-cloth and a scavenging opening buffering valve are added in a scavenging channel, and the emission reduction function and the standard reaching effect are achieved. A filter screen (58) in the scavenging channel is arranged beside a technological lap piece (55) and below the scavenging channel. The filter screen in the scavenging channel is formed by weaving a plurality of metal wires in a longitudinal and latitudinal mode and has the filtering function. The filter screen, namely, the screen cloth and the scavenging opening buffering valve, arranged below the scavenging channel and the double-screen-cloth, namely, the filter screen all have the regulating effect on air in a cylinder and breathe among crankcases. A plurality of wedges arranged on an an
