摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine provided with a scavenging control valve device for improving heat efficiency of the engine, and reducing fuel consumption by preventing generation of discharge loss of new air in a cylinder due to blowing off toward the exhaust side, and increasing effective work of cylinder gas.
SOLUTION: On either the inside or the outside of a cylinder liner, a scavenging control valve is provided to be movable along an outer surface or an inner surface of the cylinder liner to open/close a scavenging hole, and vary opening area of a scavenging passage into a combustion chamber, and a valve actuation device is provided to drive the scavenging control valve in accordance with the crank angle. The valve actuation device keeps the scavenging hole closed at a piston lowering stroke through the scavenging control valve to delay opening of the exhaust valve to the utmost for achieving the maximum effective work. It controls closing timing of the scavenging passage after a bottom dead center to be similar to valve closing timing of an exhaust valve.

摘要： PROBLEM TO BE SOLVED: To use a cylinder of a two-cycle internal combustion engine in common with a four-cycle internal combustion engine by eliminating a scavenging port in the cylinder in the two-cycle internal combustion engine. SOLUTION: A first poppet valve 12 opening at a crank angle of about 90 deg. to about 270 deg. is provided in an opening part for a cylinder of a first common port 6, and a second poppet valve 14 opening at a crank angle of about 450 deg. to about 630 deg. is provided in an opening part for a cylinder of a second common port 7. A first selector valve 19 for communicating the first common port with a first exhaust port and communicating the first common port with a first intake port in a section of opening of the first poppet valve is provided in a connection part of the first common port, the first intake port 20, and the first exhaust port 21, and a second selector valve 23 for communicating the second common port with a second exhaust port and communicating the first common port with a second intake port in a section of opening of the second poppet valve is provided in a connection part of the second common port, the second intake port 24, and the second exhaust port 25.
