    • Systems, methods, and assemblies for providing improved fuel management to fuel injected engine systems of off-road vehicles, such as snowmobiles, personal watercraft, motorcycles, utility vehicles, and all-terrain vehicles. The fuel-injected engine systems can return fuel after passing through a pressure regulator located either upstream or downstream of the engine. Fuel may be returned to the fuel pump through various routes, rather than simply returning the fuel into the fuel of the fuel tank. Fuel may be returned directly to the fuel pump upstream of all fuel pickups or upstream of some fuel pickups and downstream from other fuel pickups. Some embodiments include a vapor separator located downstream of the pressure regulator but somewhere upstream of the fuel pump.
    • 用于为越野车辆的燃料喷射发动机系统(例如雪地摩托车,私人船舶,摩托车,多用途车辆和全地形车辆)提供改进的燃料管理的系统,方法和组件。 燃油喷射发动机系统可以在通过位于发动机上游或下游的压力调节器之后返回燃料。 燃料可以通过各种路线返回到燃料泵,而不是简单地将燃料返回到燃料箱的燃料中。 燃料可以直接返回到所有燃油拾取器上游的燃料泵或一些燃料吸入器的上游,并且在其它燃料拾取器的下游。 一些实施例包括位于压力调节器下游但位于燃料泵上游的蒸气分离器。

    • In some embodiments, a fuel sump system may include one or more of the following features: (a) a fuel tank, (b) a fuel sump tank in fluid communication with the fuel tank to receive fuel from the fuel tank, (c) a fuel pump having an intake positioned in the sump tank to pump fuel from the sump tank to an engine via a fuel supply line, (d) a fuel return line in fluid communication with the engine for returning fuel the fuel return line being in fluid communication with the sump tank to supply returned fuel to the sump tank, (e) a fuel pressure regulator operably coupled to the return line, and (f) a transfer pump operatively coupled to the fuel tank and the sump tank for transferring fuel from the fuel tank to the sump tank.
    • 在一些实施例中,燃料池系统可以包括以下特征中的一个或多个:(a)燃料箱,(b)与燃料箱流体连通以从燃料箱接收燃料的燃料箱罐,(c) 燃料泵,其具有位于所述贮槽中的进气口,用于经由燃料供应管线将燃料从所述集油箱泵送到发动机;(d)与所述发动机流体连通的燃料返回管线,所述燃料返回管路用于使燃料返回管线处于流体 与贮槽相通以将返回的燃料供应到贮槽,(e)可操作地连接到返回管线的燃料压力调节器,以及(f)可操作地联接到燃料箱和贮槽的输送泵,用于将燃料从 燃油箱到油底壳。
