摘要： A first and second baffle formed of a thin sheet metal material are introduced into an engine induction system on the upstream side of air fuel metering device and interposed between the air fuel metering device and a tubular intake runner in order to prevent post engine shut down fuel boiling. The first and second baffles absorb heat from the induction system and dissipate heat to the surrounding atmosphere. The first and second baffles are sized sufficiently large to limit peak fuel temperature in the fuel metering device 130° F. when a hot engine is shut down in a 70° F. environment.

摘要： A Compact blower is provided having a housing defining an engine compartment, cooling air compartment and a volute chamber all coaxially aligned along a vertical axis. An internal combustion engine is oriented within the engine compartment with a vertically aligned output shaft and a forwardly facing fin cylinder. The rotary impeller is affixed to the engine output shaft provided with a plurality of cooling air pump blades projecting upward from a circular disc and oriented within the cooling air pump compartment. The impeller is further provided with a plurality of blower fan blades which project outwardly into the volute chamber. The rotation of the impeller causes air to be drawn into the volute chamber and discharged through the blower air discharge port. Cooling air is drawn through the cooling air pump compartment and directed across the engine and cylinder and ultimately discharged through an upper front portion of the engine compartment in a direction away from the operator.

摘要翻译： 提供了一种紧凑型鼓风机，其具有限定发动机舱，冷却空气室和围绕垂直轴同轴对准的蜗壳的壳体。 内燃机定位在发动机舱内，具有垂直对齐的输出轴和朝前的翅片缸。 旋转叶轮固定在发动机输出轴上，该发动机输出轴设置有从圆盘向上突出并定向在冷却空气泵室内的多个冷却空气泵叶片。 叶轮还设置有多个鼓风扇叶片，其向外突出到蜗壳室中。 叶轮的旋转使得空气被吸入涡卷室并通过鼓风机空气排放口排出。 冷却空气被抽吸通过冷却空气泵室并引导穿过发动机和气缸，并且最终沿着远离操作者的方向通过发动机室的上前部排出。
