Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:
Two cylinders of sweeping of new type gasoline chain saw engine, comprise the cylinder main body 1 that is connected with crankcase, described main body 1 upper end is provided with spark plug mounting hole 2, the internal chamber wall of main body is provided with groove as scavenging air belt 3, described main body both sides relatively offer suction port 4 and relief opening 5, the main body downside is one-body molded have fixed base 6, described scavenging air belt be provided with part wherein every plate 7, plate and cylinder main body are one-body molded.
Above-mentioned scavenging air belt 3 is two, is oppositely arranged on the internal chamber wall of cylinder main body both sides.
Above-mentioned fixed base is provided with air cavity 8, and described air cavity is located on the two side between two scavenging air belts.
Above-mentioned relief opening the height of lower dead center be higher than the top dead center of suction port.
Above-mentioned piston is closed suction port in the process of moving upward, moving up sweeps into relief opening with waste gas, opens suction port, to the gas injection of piston bottom, closes relief opening, and pressurized air upwards does work.
