摘要： A system and method is described for measuring fuel consumption by combustion engines operated in a manner wherein one component of fuel is used for the process of combustion itself and another complementary component of that same fuel is employed within a recirculation path for the purpose of cooling functions, for example, the cooling of fuel injectors. A fuel combiner is incorporated within the fuel delivery system having an output at the suction side of a fuel pump. One input to this fuel combiner is recirculated fuel, while the opposite input is make-up fuel from the fuel tank. The method and system employs a fluid meter which measures the flow of make-up fuel at the input to the combiner. Return or recirculating fuel is cooled and degassed with a gas phase separator in a preferred embodiment. Additionally, a thermally based flow meter provides for enhanced accuracies with the system and method.

摘要： A high pressure fuel/air injection system for an outboard motor having a V-cylinder arrangement wherein the major components of the air/fuel supply system are disposed in the valley between the cylinder banks. The system includes an vapor fuel separator that has a fuel chamber in which the supply of fuel is maintained by a float valve and an air chamber positioned above the fuel chamber and to one side of it and which communicates with the fuel chamber through a perforated member. A filter media fills the air chamber and an atmospheric air inlet is provided to the air chamber. Fuel pressure and fuel regulator valves are disposed in the area to the side of the air chamber and regulate fuel and air pressure by dumping fuel and air back to the fuel and air chambers, respectively, through integral internal conduits. The regulating system includes an arrangement for regulating the fuel pressure so that it will be at least greater than the air pressure by a predetermined amount and also for precluding the delivery of air under pressure if fuel under pressure is not supplied. The arrangement also incorporates a system for insuring that fuel cannot flow out of the atmospheric air inlet if the outboard motor is tilted up or is laid on its sides. An additional air supply is provided for the air compressor in the event the air chamber becomes clogged or inadequate to supply the air requirements for the system.

摘要： A low pressure fuel supply system supplies fuel which tends partially to solidify at low temperatures and whose viscosity increases with decreasing temperature, from a fuel tank along a supply line, through a filter, to a fuel injection pump. A fuel recirculating circuit for recirculating fuel warmed by the injection pump extends from a return outlet of the injection pump, along a path extending through the filter to the injection pump inlet. A permanent bleed pipe extends to the fuel tank from the portion of the recirculating circuit between the injection pump return outlet and the filter. The flow-resistance-determining dimensions of the permanent bleed pipe are such that the pipe presents increasing resistance to the flow of fuel therein with decreasing fuel temperature. It therefore carries little flow at low temperatures of the fuel therein, most of the warmed fuel from the injection pump return outlet being directed into the filter. Blockage of the filter by solidified portions of the fuel is thus avoided. Under normal operating conditions when the fuel temperature is higher, fuel flows more quickly through the permanent bleed pipe and so more of the warmed fuel is returned from the injection pump return outlet to the fuel tank, thus preventing overheating of the fuel and of the injection pump.

摘要： An integral fuel line for use in a fuel injection type of fuel distribution system for motor vehicles includes an innermost tube defining a high pressure line, an intermediate tube defining a low pressure line, and an outer tube defining a vapor recovery line. The innermost tube has a first passage for delivering fuel from a storage tank to an engine cylinder of a motor vehicle. The intermediate tube is spaced from and surrounds the innermost tube to form a second passage therebetween for returning the unused portion of fuel back to the storage tank. The outer tube is spaced from and surrounds the inatermediate tube to form a third passage therebetween for returning vaporized and evaporated fuel back to the storage tank.

摘要： Fuel delivery valving operatively mounted in an axially extending center bore of a high pressure pump rotor. The valve axially shifts between an open position in which a charge of fuel generated by the pump is transmitted as a pressure wave to a fuel injector nozzle and a closed position in which the pump charging chamber is sealed from the injection line and the injection line is vented to low pressure so that secondary pressure waves reflecting from the injector nozzle will be routed to the low pressure line for dissipation therein rather than rebounding from the delivery valve. This improves engine operation efficiency and eliminates seocndary injection of fuel by the injector nozzle and high hydrocarbon and smoke emissions. One embodiment has a fuel delivery valve operatively mounted in each discharge fitting of a hydraulic head assembly of the fuel injection pump.

摘要： Several embodiments of fuel supply systems for outboard motors and particularly those embodying fuel injection systems and remotely positioned fuel tanks. In each embodiment, a device is incorporated in the power head of the outboard motor for maintaining a uniform pressure of fuel delivery to the fuel injection nozzles by recycling a portion of the fuel back into the fuel system and within the power head. In some embodiments, the fuel is recycled directly into the fuel line before the fuel pump. In others, the fuel is recycled to either a delivery tank or an accumulator chamber.

摘要： An assembly for a fuel injection system for use with an internal combustion engine, comprises a fuel injection system component and a plurality of injectors mounted on the component. The component comprises a plurality of air passages for supplying air into the engine, a plurality of injector seats and a fuel passage communicating with the injector seats. Each injector has a vapor discharge passage communicating with the inside of the injector and with the fuel passage, and/or has a filter inserted in the fuel passage so that fuel vapor in the injector is smoothly discharged from the injector into the fuel passage, thereby preventing vapor lock of the injector system. The component may be directly mounted to a surge tank so that an independent intake manifold need not be used.
