Abstract
A two-cycle internal combustion engine including: a cylinder; an exhaust opening provided in a portion, on one side in the peripheral direction, of the cylinder; a plurality of scavenging openings for performing schnurle scavenging, the scavenging openings being located at positions which are laterally symmetric with respect to a cylinder symmetric plane containing the exhaust opening and the center line of the cylinder; a chamber portion adjacent to the cylinder; a communication passage for communicating the cylinder to the chamber portion, the communication passage having a cylinder side opening located opposite to the exhaust opening with respect to the center line of the cylinder; and a control valve for openably/closably controlling the communication passage so as to blow a rich air-fuel mixture into the combustion chamber from the cylinder side opening of the communication passage by a high compression gas stored in the chamber portion.
