Claims

[Scope of utility model registration request]

The intake passage of the intake hole of the cylinder opposite to the exhaust hole of the cylinder is formed into a mixture passage for mixing fuel and air and an air passage for only intake of air,
Each of these passages is provided with a different throttle valve provided on the same axis, and the mixture passage and the air passage are arranged in a vertical plane of the cylinder passing through the center of the cylinder and the center of the exhaust hole. On the other hand, the holes are opened in opposite directions, and the scavenging passage on the same side as the air mixture passage makes an angle with the vertical plane of the cylinder. A 2-cycle engine characterized by having a smaller angle than the
