摘要: A two-stroke internal combustion engine (1) is provided with one pair or plural pairs of C-shaped scavenging passageways (31, 32) of a reverse flow system where scavenging inlet ports (31a) as well as scavenging outlet ports (31b, 32b) are both opened to a cylinder bore (10a), wherein a scavenging introducing passageway (40) for introducing an air-fuel mixture (K) from a crank chamber (18) into the scavenging inlet ports (31a) is provided between the cylinder bore and the piston adapted to reciprocatively move up and down in the cylinder bore (10a), and an effective opening area of the scavenging inlet ports (31a) is gradually decreased due to the piston (20) in the course of descending stroke of the piston (20).
