摘要： A liquid quantity visual confirmation device comprises a first reservoir-forming member, and a second reservoir-forming member forming a liquid reservoir in combination with the first reservoir-forming member. The second reservoir-forming member is at least partially transparent to allow visual confirmation of the internal liquid level from an outside thereof. The second reservoir-forming member has a liquid-feeding port for feeding the liquid into the liquid reservoir. The quantity of liquid in the liquid reservoir can be confirmed by looking at the internal liquid level in the second reservoir-forming member from the outside. It is also possible to reliably feed the liquid into the liquid reservoir from the liquid-feeding port while confirming any rising of the liquid level through the transparent portion.
摘要翻译：液量视觉确认装置包括第一储存器形成构件和与第一储存器形成构件组合形成液体储存器的第二储存器形成构件。第二储存器形成构件至少部分透明，以允许从其外部目视确认内部液面。第二储液器形成构件具有用于将液体供给到液体储存器中的供液口。可以通过从外部观察第二储存器形成构件中的内部液面来确认储液器中的液体量。也可以从液体供给口将液体可靠地送入液体储存器，同时确认液面通过透明部分的任何上升。

摘要： The present invention provides an air-cooled four-stroke internal combustion engine capable of achieving a high degree of cooling. 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.
摘要翻译：本发明提供一种能够实现高冷却度的风冷四冲程内燃机。本发明涉及一种风冷四冲程内燃机，其包括曲轴和由曲轴可旋转地驱动的风扇转子，以产生用于冷却发动机的冷却空气。发动机包括设置在曲轴下方的油盘。油盘下面形成的空间沿着油盘的下表面在曲轴的轴向方向上延伸，并允许冷却空气通过。下表面的上游部分在沿着曲轴的轴线截取的垂直截面中朝向上游向上倾斜，以在其中接收冷却空气。
