Two-cycle engine with scavaging passage

A two-cycle engine comprising:

• a cylinder including a cylinder bore and a combustion chamber connected to one end of the cylinder bore in an axial direction of the cylinder bore;
• a crankcase disposed on the cylinder and provided with a crank chamber connected to an opposite end of the cylinder bore in the axial direction;
• a piston configured to reciprocate in the cylinder bore;
• and
• an injector configured to inject fuel into the crank chamber,
• wherein the cylinder is provided with:
• an intake port communicating with the cylinder bore and configured to introduce air into the cylinder bore;
• an exhaust port communicating with the cylinder bore and configured to discharge exhaust gas from the cylinder bore;
• and
• a scavenging passage configured to send a mixture to a first region closer to the combustion chamber than a piston head of the piston in the cylinder bore in a scavenging stroke,
• wherein a scavenging outlet and a scavenging inlet of the scavenging passage open on a bore inner peripheral surface of the cylinder bore, respectively, and
• wherein, in the scavenging stroke, the scavenging outlet is located closer to the combustion chamber than a piston head of the piston on the bore inner peripheral surface, the scavenging inlet is located closer to the crank chamber than the piston head on the bore inner peripheral surface, and the first region and a second region closer to the crank chamber than the piston head in the cylinder bore communicate with each other via the scavenging passage.
