Beschreibung
Zusammenfassung:	Size reduction and pollution reduction are promoted in a two cycle engine. A two cycle engine includes: a cylinder which contains a piston so as to allow reciprocating movement of the piston; a scavenging gas reserving chamber which covers a lower opening of the cylinder so as to seal the lower opening; an intake portion which is provided in the scavenging gas reserving chamber; a scavenging passage which provides communication between the scavenging gas reserving chamber and the cylinder; a connecting rod which is connected to the piston and passes through the scavenging gas reserving chamber; a crank mechanism which allows linear reciprocating movement of the connecting rod; and a sealing portion which is provided in an insertion hole in the scavenging gas reserving chamber through which the connecting rod passes and which allows linear reciprocating movement of the connecting rod but seals the scavenging gas reserving chamber. The two cycle engine may have a structure in which the intake portion has a structure for drawing outside air into the scavenging gas reserving chamber and in which a spraying mechanism for spraying fuel is provided in the cylinder head.
