Title: Uniflow type two cycle engine
IPC: F02F1/22
Filed: 1992-03-31
Abstract: PURPOSE:To lighten an engine, and also enable fresh air to be sucked in a small range smoothly by forming an upper part from the lower edge part of port in a thick wall, and forming a lower part in a thin wall, in the case of a cylinder wall positioned in the vicinity of a deviation port for deviating scavenging flow. CONSTITUTION:A scavenging port 9 consists of a port 9a arranged toward the axial core of a cylinder bore 2, and a port 9b in a tangent direction arranged in a circumferential direction, so that a swirl of new air may be generated in the cylinder bore 2. A cylinder wall 11 in a range in which a head bolt 14 is arranged, is provided in the vicinity of a boss part, and it is difficult to ensure an enough space for suction on the suction side of the scavenging port 9. As a result, the wall thickness of the lower edge part 30 of the scavenging port 9 is reduced to the same wall thickness as the lower wall of the wall 11. Therefore, new air in an intake chamber 8 is also led-in from the bottom side of the scavenging port 9. It is thus possible to reduce the wall thickness of the cylinder wall 11 so as to form an engine in a light weight, and also ensure the length of the scavenging port 9 in order to ensure direction of scavenging flow so as to strengthen intake drift current.
