摘要： PROBLEM TO BE SOLVED: To provide a two-stroke prime mover capable of scavenging an overflow pipe line completely by air containing no fuel, at a low structural cost. SOLUTION: A valve 23 is located in the second switching position when a piston 1 closes an overflow port 12 in an up-stroke, and the overflow pipe line 10 is connected to an air pipe line 21 and a storage chamber 20 to store the air containing no fuel inside the pipe line 10 as storage air 51. When the piston 1 comes to a down-stroke to open the overflow port 12, the valve 23 is changed to the first switching position, the overflow pipe line 10 is separated from the air pipe line 21 and the storage chamber 20 to be connected to a crank casing 3, and fresh air-fuel mixture compressed by down-motion of the piston 1 flows into the pipe line 10 along an arrow-mark direction 41 to push away the storage air 51 from the pipe line 10 into a combustion chamber 4.

摘要： PROBLEM TO BE SOLVED: To improve an internal combustion engine in a manual working machine provided with the air-cooled internal combustion engine disposed in a machine casing to drive a tool, and a blower impeller enclosed in a cooling air spiral body fixedly held to a crankshaft of the internal combustion engine, and opened to the internal combustion engine, and allowing ambient air to be taken into the cooling air spiral body and supplied to the internal combustion engine through an air inlet formed in the machine casing. SOLUTION: A second cooling air inflow port 8 is formed at a bottom part 7 of the cooling air spiral body 5 positioned between the blower impeller 4 and the internal combustion engine 2. An intake chamber 6 of the machine casing 3 is thereby connected to a cooling air guide part of the cooling air spiral body 5.
