Claims

[Scope of utility model registration request]

It has a house air hole and an auxiliary scavenging hole that communicate from the crank chamber to the cylinder chamber, and the auxiliary scavenging hole is opened in the intake passage in which a check valve such as a reed valve connected to the crank chamber is interposed in the middle of the passage. A two-cycle internal combustion engine characterized in that a partition wall is disposed facing the check valve from one side of the opening of the auxiliary scavenging hole to the intake passage close to the check valve.
