Abstract
Systems are disclosed for supplying fuel to fuel-injected gensets in a recreational vehicle. An apparatus includes a fuel injection system having a fuel reservoir and a first pump fluidly coupled to the first reservoir and structured to supply fuel to the fuel reservoir. The fuel injection system is further provided with a pressure sensor and a second pump. The second pump is fluidly coupled to the pressure sensor and structured to provide pressurized fuel from the fuel reservoir to one or more fuel injectors of an associated engine. The second pump is a variable speed fuel pump.
Claims22
An apparatus, comprising:
- circuitry configured to:
- receive pressure data indicative of a fuel pressure out of a variable speed fuel pump structured to provide fuel to an engine of a recreational vehicle genset of a recreational vehicle;
- compare the pressure data to a predetermined value;
- adjust a control signal transmitted to the variable speed fuel pump and control a speed of the variable speed fuel pump responsive to the comparison;
- adjust pressurization of fuel pumped by the variable speed fuel pump from a fuel reservoir arranged to receive fuel from a fuel tank of the recreational vehicle;
- and
- control the variable speed fuel pump to maintain a constant fuel pressure without a pressure regulator, and
- control a return of excess fuel from the fuel reservoir to the fuel tank of the recreational vehicle, and
- an electrical connector extending from a portion of the fuel reservoir and disposed so as to be contained between a fuel inlet and a fuel outlet in a lateral direction of the fuel reservoir.
A method, comprising:
- receiving, via circuitry, pressure data indicative of a fuel pressure out of a variable speed fuel pump structured to provide fuel to an engine of a recreational vehicle genset of a recreational vehicle;
- comparing the pressure data to a predetermined value;
- transmitting a control signal to the variable speed fuel pump;
- adjusting the control signal transmitted to the variable speed fuel pump and controlling a speed of the variable speed fuel pump responsive to the comparison;
- adjusting pressurization of fuel pumped by the variable speed fuel pump from a fuel reservoir arranged to receive fuel from a fuel tank of the recreational vehicle;
- controlling the variable speed fuel pump to maintain a constant fuel pressure without a pressure regulator, and
- controlling a return of excess fuel from the fuel reservoir to the fuel tank of the recreational vehicle,
- wherein an electrical connector extends from a portion of the fuel reservoir and is disposed so as to be contained between a fuel inlet and a fuel outlet in a lateral direction of the fuel reservoir.
