摘要： An outboard motor for a watercraft includes a simply structured fuel supply system of a smaller size and a longer life than prior fuel supply systems. The fuel supply system includes a delivery fuel tank carried by the outboard motor. Fuel is pumped from an external fuel supply tank carried by the watercraft to the delivery fuel tank by a low-pressure fuel pump located within the outboard motor. A control system controls the low-pressure fuel pump so that a predetermined level of fuel is maintained in the delivery fuel tank. The control system includes a fluid level detection sensor that detects the level of fuel within the delivery fuel tank and produces a corresponding signal indicative of the fuel level. A control unit circuit receives the fluid level signal and determines if the fluid level in the tank is higher or lower than a predetermined maximum fuel level. If the fluid level is determined to be higher than a maximum fuel level, the control unit circuit deactivates the low-pressure fuel pump. If the fluid level is determined to be lower than the maximum fuel level, the control unit circuit activates the low-pressure fuel pump.
摘要翻译：用于船舶的舷外马达包括具有比现有燃料供应系统更小尺寸和更长寿命的简单结构化的燃料供应系统。燃料供给系统包括由舷外马达承载的输送燃料箱。燃料由位于舷外马达内的低压燃油泵从船舶所携带的外部燃料供给箱泵送到输送燃料箱。控制系统控制低压燃料泵，使得在输送燃料箱中保持预定水平的燃料。控制系统包括液位检测传感器，其检测输送燃料箱内的燃料水平并产生指示燃料液位的相应信号。控制单元电路接收液位信号，并确定油箱中的液位是否高于或低于预定最大燃油量。如果液面被确定为高于最大燃料液位，则控制单元电路使低压燃料泵无效。如果液面被确定为低于最大燃料液位，则控制单元电路启动低压燃料泵。

摘要： An air intake system for an engine powering an outboard motor is disclosed. The engine is positioned within a cowling of the motor, the cowling including an air intake vent. The engine is vertically positioned, having a camshaft drive at an upper end thereof, the camshaft drive enclosed by a drive cover. An air passage is defined between the drive cover and cowling and leads from the vent to an engine air intake. The air intake comprises a passage formed by the cover and extending therethrough. The passage through the cover leads to a throttle body having a throttle plate therein, the throttle body connected to a surge tank from which runners extends to provide air to the combustion chambers. Air flows through the passage in the cover through a flexible hose member extending between the cover and the throttle body.
