CONSTITUTION:In a cylinder block 3 of an engine body 1, a scavenging-cum- suction port 5, opening each to a cylinder port 3a and a crankcase 2a, is formed in the one side wall, while an exhaust port 6, opening to the cylinder port 3a, is formed in the other side wall. And, plural scavenging ports 81 and 82, interconnecting the crankcase 2a to the cylinder port 3a, is formed at both side walls of the cylinder block 3 between these ports 5 and 6. In this constitution, a partition wall 10 between the exhaust port 6 and the second scavenging port 82 is set up in a tilt, and these ports 6 and 82 are overhung to the opposite side each other. An upper end of the partition wall 10 and an intermediate part at the lower edge of the second scavenging port 82 are connected by a connecting wall 11.

摘要： PROBLEM TO BE SOLVED: To improve a lubricating condition further by gradually deepening an oil sump groove to collect mixed oil scraped up at a rotational weight part provided on a crankcase and to send it to a driving gear engaging part through a communicating passage along the rotational direction of the weight part. SOLUTION: A crank chamber 24a of a crankcase 24 is furnished with a housing part 24b to store a bearing, a side wall 24c and a peripheral wall 24d. The side wall 24c has an oil sump groove 24e and a communicating passage f opening, and the peripheral wall 24d has an oil sump groove 24g and an erected wall 24h. The oil sump groove 24e is divided into a flat part 24j a bottom of which is flat and an inclined part 24k a bottom of which is inclined on a border line 24m. The oil sump grooves 24e, g are continued to each other, and the rotational direction of a crankshaft weight part is an arrow direction. The oil sump grooves 24e, g gradually deepening along the rotational direction of the weight part can collect splashed mixed oil in a deep part by centrifugal force and improve oil collecting capacity. Consequently, lubricity of an engaging part of a driving gear is improved.

摘要： PURPOSE:To improve cooling efficiency and maintenance workability by constructing a shroud of at least plural members including a head corresponding member covering a cylinder head from its front side and fastening the head corresponding member on the cylinder head while setting its fastening direction along the axial line of the cylinder block. CONSTITUTION:In a shroud 36, the first member 37 covering a cylinder head 26 and a cylinder block 27 from the front side and the second member 38 covering the rest parts are connected together. The first member 37 is fastened in the cylinder head 26 by means of plural mounting bolts 41. Therefore, the clearance between the cylinder head 26 and the shroud 36 can be strictly set, while the clearance between the shroud 36 and the cylinder head 26 can be easily narrowed so that a flow resistance larger than the flow resistance when cooling air flows between fins 39 in the cylinder head 26 is generated, and consequently, flow of the cooling wind is prevented as much as possible, and as a result, cooling efficiency is increased, while workability for engine maintenance can be improved.

摘要： PURPOSE:To aim at improvement in the output of an engine under a simple structure through preventing an abnormal combustion by providing a notch on the intake port side or the exhaust port side of at least either one of the peripheral edge on the under surface of a cylinder head and the peripheral edge on the under surface of a piston. CONSTITUTION:A combustion chamber 8 is comprised of a central part 7a1, which is shaped in the dome-form and placed on the under surface of a cylinder head 7, and a peripheral part 7a2, which constitutes a very small clearance between the peripheral part 7a2 and the upper surface 5a of a piston 5 at the top dead point. In addition, on the exhaust port 3 side peripheral edge of the peripheral part 7a2 are provided a pair of notches 7a3, 7a3 along a semicircle. Thereby, when the piston 5 is placed at the top dead point, there are provided a dome-like dome area 8a in the central part, a gap-like squishy area 8b in the peripheral part and a pair of groove-like spaces 8c, 8c in the circumferential direction of the exhaust port 3 side of the peripheral edge of the squishy area 8b. When the piston 5 comes up, the fuel-air mixture in the squishy area is squeezed to flow in the dome area, and at the same time, a part of it also flows in the groove-like spaces 8c to generate a turbulent flow so that the mixing of fuel and air is performed sufficiently.
