    摘要： A two-stroke internal combustion engine in a working machine such as a chain saw has been prone to stalling when the stance of the machine was changed from slanting down to slanting up. Such stalling is minimized when lower longitudinal scavenging passage in the cylinder block of the engine have smaller cross section as compared with upper scavenging passage, and when the crank chamber of the engine includes a flow restricting portion for impeding the flow of liquid fuel into the lower scavenging passage when the stance is changed. The engine has a cylinder block (12), a crankcase (20), scavenging passages (27, 27), and a flow restricting portion (40) on an inner peripheral surface (22a) of the crank chamber (22).

    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).

    摘要： A loop scavenge two-cycle internal combustion engine that includes a partial wall partition disposed between a scavenging path and a cylinder bore, with a cooling port formed in the partial wall partition for enabling fresh gas in the scavenging path to contact directly with a peripheral wall of a piston in the cylinder. The fresh gas in the scavenging path directly contacts and efficiently cools the peripheral surface of the piston to prevent heat rise and distortion within the engine. The partial wall partition and cooling port maximize both cooling efficiently and cylinder strength and durability.
