发明名称 Injection system for watercraft engine
摘要 An improved arrangement of a fuel injection system within a personal watercraft reduces the likelihood that certain sensitive components of the fuel injection system will contact water, regardless of the orientation in which the watercraft floats. Because of the sporty nature of personal watercraft, these boats often are inverted or laid on their sides. The fuel injectors of the fuel injection system are positioned within an engine compartment of the watercraft so as to remain above the water surface level with the watercraft in any orientation. In one mode, the fuel injectors also are positioned above the ends of air ducts through which air is introduced into the engine compartment. The fuel injectors are also shielded by protective covers. As a result, the occurrences of water contacting the fuel injectors is reduced.
