20100101535 | FUEL RAIL VENT SYSTEM - A fuel rail vent system for evacuating air from a fuel rail includes a first fuel reservoir and a first fuel line extending between the first fuel reservoir and the fuel rail. A fuel pump is configured in fluid communication with the first fuel reservoir to pump liquid fuel from the first fuel reservoir to the fuel rail through the first fuel line. A second fuel line separate from the first fuel line extends between the first fuel reservoir and the fuel rail. A primer system is configured for fluid communication with the first fuel reservoir to pump liquid fuel from the first fuel reservoir to the fuel rail through the second fuel line. A second fuel reservoir separate from the first fuel reservoir is configured for fluid communication with the fuel rail downstream of the fuel rail to receive any excess liquid fuel and/or fuel vapor upstream therefrom. | 04-29-2010 |
20110048386 | FUEL VAPOR SEPARATOR WITH EVAPORATIVE EMISSIONS CHAMBER AND MARINE FUEL SYSTEM AND ENGINE THEREWITH - A unitized fuel vapor separator and evaporative emission device; marine fuel system, and marine engine therewith are provided. The device includes a fuel vapor separator and evaporative emissions chamber having a common wall separating the fuel vapor separator from the evaporative emissions chamber. The fuel vapor separator is configured for fluid communication with an upstream fuel tank and with a fuel pump and has a fuel vapor outlet to channel fuel vapor outwardly therefrom. The evaporative emissions chamber is configured for fluid communication with the fuel tank to receive fuel vapor therefrom and has an adsorption material for adsorbing fuel vapor and dissipating air from the fuel vapor through an air outlet to channel the air outwardly therefrom. | 03-03-2011 |
20110132469 | SNAP ASSEMBLY DECOUPLED FLOAT VAPOR VENT APPARATUS - This invention relates generally to a vapor vent system for an internal combustion engine such as an outboard marine fuel injected engine. The vapor vent system includes a snap assembly decoupled float vapor vent in order to vent vapors from the vapor separator. The snap assembly design reduces costs, vibration and assembly requirements. | 06-09-2011 |
20120156058 | VOLTAGE COMPENSATING PISTON FUEL PUMP AND FUEL DELIVERY SYSTEM THEREWITH - A piston-type fuel pump is provided. The fuel pump includes a housing bounding an internal cavity with a cylindrical tube disposed in the internal cavity. The cylindrical tube provides a bore extending along an axis and a piston is disposed in the bore. A spring is configured to bias the piston in a first direction along the axis. A coil is disposed about the cylindrical tube and a control circuit is disposed in the internal cavity. The control circuit is configured in electrical communication with the coil. The voltage supplied to the control circuit can be varied, with the control circuit compensating for the variable supply voltage to regulate the actuation of the coil from a de-energized state to an energized state. The piston is biased in a second direction opposite the first direction in response to the coil being actuated. | 06-21-2012 |
20120186562 | FUEL LEVEL SENSOR FOR MARINE FUEL VAPOR SEPARATOR EXTERNAL TO UNIT - A fuel vapor separator assembly including a housing having an open interior and a float disposed therein. At least one magnet is disposed on the float, and a sensor assembly which is responsive to magnetic fields is disposed externally of the housing. The sensor assembly senses the position of the float to determine whether vapor is present in the fuel vapor separator. If the sensor assembly determines that vapor is present in the fuel vapor separator, then it generates a signal, which a controller receives and activates a vapor vent valve to discharge the vapor and/or activates a fuel lift pump to pump additional fuel into the fuel vapor separator. The sensor assembly could be, for example, a Hall effect sensor or a reed-type sensor. | 07-26-2012 |

20110168138 | VAPOR SEPARATOR WITH INTEGRAL LOW PRESSURE LIFT PUMP - A system for supplying fuel under pressure to an internal combustion engine, and to control fuel delivery to a fuel injection system in an internal combustion engine having a low pressure pump formed integrally as at least part of a main housing of a vapor separator assembly. The low pressure pump lifts fuel into a cavity of a reservoir, which is drawn from a high pressure pump into the internal combustion engine. Due to the integrated nature of the low pressure pump, leak paths and assembly costs are reduced. | 07-14-2011 |
20120103284 | THERMOELECTRIC COOLED PUMP - In invention relates to an engine cooling system in which the supply of fuel is cooled to prevent fuel vapors by cooling the fuel pump. The cooling system uses a thermoelectric material that, either entirely or partially, surrounds the fuel pump, is the housing of the fuel pump and/or is internal to the fuel pump. | 05-03-2012 |
20120180765 | DIESEL FUEL SYSTEM WITH ADVANCED PRIMING - This invention relates to an aerating device for a fuel system, and in particular, to an aerating device for a fuel system supplying fuel to an engine from a fuel tank. The invention includes, for example, a solenoid valve accessing a flow path to the fuel tank, and a control unit opening a closing the solenoid valve, such that opening of the solenoid valve permits fuel and air to flow back through the flow path to the fuel tank and naturally separate. | 07-19-2012 |
