Abstract: A cylinder and a method for manufacturing a cylinder for an internal combustion engine is provided which avoids the generation of a step portion at the scavenging port without necessitating enhanced precision of the positioning of the working tools or the working location. A raw cylinder body is cast-molded with the scavenging port portion thereof being left closed. Subsequently, this closed scavenging port portion is cut out (or opened) by means of cutting work, etc. The cutting out of the closed scavenging port portion is performed by widening the cylinder bore side thereof at predetermined angles to the planes of the inner wall of the hollow scavenging passageway formed contiguous to the closed scavenging port portion.

Abstract: An engine intake control mechanism has a throttle valve that can be rotated to a cold-starting position in response to the closing movement of a choke valve and, even if the throttle valve is opened beyond the cold-starting position, the choke valve is retained at the cold-starting position. Only when the throttle valve is subsequently actuated to return to its original closed position is the choke valve automatically returned to its original opened position. The engine intake control mechanism is especially useful in top handle type portable power working machines, which are subject to undesirable movements of the throttle control lever on the top handle when the engine is being started.

The present invention is directed to an air-cooled four-stroke internal combustion engine including a crankshaft and a fan rotor rotatably driven by the crankshaft to generate cooling air for cooling the engine. The engine comprises an oil pan disposed below the crankshaft. A space formed below the oil pan extends in the axial direction of the crankshaft along the lower surface of the oil pan and allows a cooling air to pass therethrough. An upstream portion of the lower surface is inclined upward, toward the upstream, in a vertical section taken along the axis of the crankshaft to receive the cooling air therein.
