Furthermore, in the installed state, in which the connection element is resting via its locating area against the outer side of the component, the locating area has the form of a cylinder jacket. In addition, a system having a component and such a holder is provided.

An electronic fuel injection throttle body unit has a core body with two side components. The two side components each including a fuel delivery passage. Four air intake passages extending vertically through the throttle body. Valves are rotatable within the air intake passages. The valves being connected to valve shafts that rotate about respective valve shaft axes. The valve shaft axes and the fuel delivery passages are perpendicular to each other.

To improve the ability to layout delivery pipes by maintaining flexibility in a mounting position of an inlet pipe to a delivery pipe main body. A delivery pipe for gasoline comprising a flat shaped delivery pipe main body 1 provided with a pair of facing wide walls 2, 3 and a pair of facing narrow walls 4, 5 that are more narrow than the pair of wide walls 2, 3, wherein an inlet pipe 7 is disposed and connected to the narrow wall 4 of the delivery pipe main body 1, and a connecting portion 10 of the inlet pipe 7 and the narrow wall 4 is covered continuously by a reinforcing material 11 from the connecting portion 10 over the wide walls 2, 3, thereby reinforcing the connection portion 10.

Provided is a protective structure (64) for a fuel pipe (45) extending along the intake side of an engine main body (9) under an intake manifold (20). A protective member (61) is placed in front of the fuel pipe. The protective member includes a pair of legs (64, 65) secured to the intake side of the engine main body, a main body (63) extending from the legs upward in an arcuate manner along a front side of the fuel pipe and bent rearward in an upper part thereof, and an abutting projection (63G) extending from an upper end of the main body and projecting upward and rearward. A fastening member (26, 27) is passed through a flange of the intake manifold, and includes an engagement feature (36) positioned behind a free end of the abutting projection. The protective member minimizes the loading transmitted to the fuel pipe at the time of a vehicle crash.

An internal combustion engine includes first and second common rails each having a metering or pressure regulating valve, with the valves settable at different pressure values from one another. Rotors are each sealingly and rotationally received within a respective cavity to define at least one combustion chamber of variable volume. The engine includes first and second fuel injectors for each of the rotors. Each first fuel injector is in fluid communication with the first common rail and each second fuel injector is in fluid communication with the second common rail. A method of feeding fuel in an internal combustion engine is also provided.

An outboard motor engine has a cylinder block including vertically stacked cylinders divided into two cylinder banks arranged in a V-shape. Two cylinder heads define intake passages, each intake passage corresponding to a respective cylinder. Air intake manifolds include air intake runners that extend from an opposite end of the engine, around outer sides of the cylinder block, and respectively connect to the intake passages. Two vertically extending fuel rails are respectively located between the first cylinder head and the first air intake manifold and between the second cylinder head and the second air intake manifold. The fuel rails are integral with either the respective cylinder heads, or the respective air intake manifolds. Fuel injectors are coupled to the fuel rails and vertically spaced from one another with respect to each fuel rail such that each fuel injector is associated with a respective cylinder.

Disclosed is a vehicle. The vehicle generally includes a frame to support an engine and one or more ground supports, such as wheels, to support the frame. The engine may include an internal combustion power plant and a fuel supply system therefore.

A fuel delivery system for a vehicle having an engine includes a fuel injection system, a fuel supply line configured to supply fuel from to the fuel injection system, and a fuel pressure sensor. An active expansion chamber (AEC) accumulator is fluidly coupled to the fuel supply line and includes a housing defining an interior chamber and an adjustable expansion chamber, a plunger assembly separating the interior chamber and the adjustable expansion chamber, and an actuator configured to selectively move the plunger assembly to actively adjust a volume of the adjustable expansion chamber. A controller is configured to detect a pressure change condition in the fuel delivery system and, in response, automatically adjust the volume of the adjustable expansion chamber to maintain the pressure of the fuel delivery system below a predetermined threshold to thereby facilitate preventing fuel leakage at the fuel injectors when the engine is shut off.

A fluid distributor for an injection system, in particular a fuel distributor rail for a fuel injection system for mixture-compressing, spark ignition internal combustion engines. The fuel distributor includes a tubular base body, which is preferably processed by a one-stage or multi-stage forging process, a first high-pressure output, a second high-pressure output, a third high-pressure output, and a fourth high-pressure output being provided at the base body. The second high-pressure output is situated offset by a predefined distance compared to the first high-pressure output in a first direction along a longitudinal axis of the tubular base body. The third high-pressure output is situated offset by the predefined distance compared to the second high-pressure output along the longitudinal axis in the first direction, the fourth high-pressure output being situated offset by the predefined distance compared to the third high-pressure output along the longitudinal axis in the first direction.
