A fuel delivery injector includes a housing, an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity, and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity. A magnetic assembly is fixedly positioned within the cavity, and a pumping assembly includes a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position. A valve is positioned within the piston and is movable between an open position and a closed position. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.

An outboard motor (10) includes a V-engine (20) having a left bank (BL) and a right bank (BR) extending obliquely toward a rear left side and a rear right side, respectively, relative to a crankshaft (21) extending in a vertical direction. An intake device (18) is provided between the left bank and the right bank, and catalyst devices (62L, 62R) that treat exhaust gas are disposed rearward of cylinder heads (24L, 24R) of the left bank and the right bank.

A fuel pressure accumulator for a fuel supply circuit of a turbine engine having at least one pipe is provided. The fuel pressure accumulator generally includes at least one housing adjacent to said pipe and receiving at least one deformable enclosure confining a gas and having at least one movable wall in contact with the fuel in order to dampen a fuel overpressure, where the housing is coaxial with the pipe and the accumulator has a permeable chamber delimited at least partially by the housing, pressurizing the deformable enclosure and communicating with the main fuel flow via a grid with staged walls tilted, with respect to a direction of the flow flowing along the grid, substantially in the direction of the deformable enclosure.

There is disclosed a method of operating an engine assembly including an internal combustion engine, a common-rail injector for injecting fuel in a combustion chamber of the internal combustion engine, and an oil circuit for lubricating components of the engine assembly. The method includes: injecting fuel in the combustion chamber via the common-rail injector; and exchanging heat between a backflow of fuel from the common-rail injector with oil of an oil circuit of the engine assembly.

A pressure-regulating device for a fuel consumption measurement system includes a fuel supply line which supplies fuel to a consumer, a fuel return line, a bypass line which branches off from the fuel supply line, a pressure regulator which sets a free flow cross-section in the bypass line, a pressure sensor arranged at the fuel supply line downstream of where the bypass line branches off, a control unit electrically connected to the pressure sensor, and a pressure-reducing element arranged in the fuel supply line upstream of the pressure sensor and downstream of the branch of the bypass line. The bypass line fluidically connects the fuel supply line to the fuel return line and feeds fuel from the fuel supply line to the fuel return line while bypassing the consumer. The pressure sensor provides pressure measurement values. The control unit regulates the pressure regulator depending on the pressure measurement values.

A fuel delivery injector includes a housing, an end cap including an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity, a magnetic assembly fixedly positioned within the cavity, and a pumping assembly including a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position and a valve assembly including a biasing spring is positioned between an inlet chamber and an outlet chamber. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.

The present invention relates to a method for controlling a fuel tank arrangement (100) connected to a prime mover (101) for propulsion of a vehicle. More particularly, the fuel tank arrangement (100) comprises a first (102) and a second (104) fuel tank connected to the prime mover of the vehicle.

A work machine includes an engine, a fluid path via which a fuel oil is supplied to the engine, a first filter provided in the fluid path, a pump provided between the engine and the first filter in the fluid path to suck and output the fuel oil, a second filter provided between the engine and the pump in the fluid path, and a third filter provided between the engine and the second filter in the fluid path.

The present disclosure relates to a method for determining the methane index of a hydrocarbon-containing combustion gas mixture which has natural gas or biogas, having the steps: flowing the gas mixture through a measuring assembly; determining a first value of a first measurement variable related to a viscosity of the gas mixture; determining a second value of a second measurement variable related to a density of the gas mixture; determining a pressure value of the gas mixture, said pressure value belonging to the first value and the second value; determining a temperature value of the gas mixture, said temperature value belonging to the first value and the second value; and determining the methane index as a function of the first value, the second value, the pressure value, and the temperature value.

A fuel system for a motor vehicle includes a fuel pump having a first pump outlet connectable to an engine fuel inlet and a second pump outlet, a fuel pump module including an internal volume, a fuel pump module outlet is arranged in the internal volume fluidically connected to the second pump outlet, and a fuel valve is fluidically connected to the second pump outlet. The fuel valve is operable to fluidically isolate the fuel pump from the fuel pump module when fuel in the internal volume reaches a selected fuel level.
