摘要： A two-stroke internal combustion engine is disclosed capable of reducing the number of pieces constituting the main body, thereby making it possible to reduce the number of parts such as assembling bolts and hence to reduce the manufacturing cost as well as the weight thereof while ensuring the rigidness of the main body. The main body of the engine includes a cylinder portion in which a piston is adapted to be fittingly inserted and a crankcase portion in which a crank shaft is rotatably supported via a bearing wherein the crankcase portion is constructed such that it is split into an upper and a lower crankcase portion by a horizontal plane which passes through a central axial line of the crankshaft, where the upper crankcase portion is integrated with the cylinder portion, thus forming an integral cylinder-case, and a fan case base is formed integral with the lower crankcase portion.

摘要： A two-stroke internal combustion engine has an air passageway for introducing air into a scavenging passageway communicating a combustion/actuating chamber disposed above a piston with a crankcase and an air-fuel supply passageway for introducing an air-fuel mixture from a carburetor into the combustion/actuating chamber. On the descending stroke of the piston, an exhaust port opens before a scavenging port formed at an upper end of the scavenging passageway opens, and an air-fuel mixture-feeding port disposed at a downstream end of the air-fuel supply passageway is opened a moment after the scavenging port is opened. Thus, air is introduced into the combustion/actuating chamber prior to the introduction of the air-fuel mixture.
