摘要:
At an outlet portion of an injection hole (8) of a fuel injection valve (1), through removal of a part (A1, 7B) of a wall forming the injection hole (8), a restriction to a spray flow is released, thereby, a deflection spray is formed in which the spray is rich at the side of restriction released and is learn at the side of restricted, accordingly, ignition property of an internal combustion engine is improved, and an optimum spray is realized which reduces exhaust amount of unburnt gas components.

摘要:
At an outlet portion of an injection hole (8) of a fuel injection valve (1), through removal of a part (A1, 7B) of a wall forming the injection hole (8), a restriction to a spray flow is eliminated, thereby, a deflection of the spray occurs in which the spray is rich at the side where this restriction is released and is lean at the side that is restricted. Thus, the ignition property of an internal combustion engine is improved, and an optimum spray is realized which reduces the amount of unburnt gas components being exhausted.

A fuel spray is directed toward an ignition plug. To an injection bole outlet portion of a swirl type fuel injector, an L-shaped cut out is provided, and the fuel spray is formed with a deflection fuel spray which has a strong swirl component that can inject with a large quantity. Accordingly, a reduction in the discharge HC amount and an improvement in the fuel consumption can be attained.

In a spray characteristic in a direct injection system gasoline engine use electromagnetic system fuel injector, to a piston cavity a mixture of fuel and air having a combustible concentration is converged and making rich the mixture having the combustible concentration at a side of ignition plug, then an ignition performance is improved and making thin the mixture of fuel and air to a piston direction a combustion performance is improved, namely it is necessary to generate a flat inclined spray. A part of a wall face for forming the injection hole at an outlet portion of the injector is formed with V groove according to two inclination faces with optional angles against a center axial line of the injection hole or a substantially recess shape step-wise rectangular groove having different cut-off depths.
摘要:
For each of the injection holes on the face of a plate member which is disposed in a fuel passage, grooves are provided which run along the circumferential direction of the respective injection holes, and at the positions of the grooves, fuel overflows are formed. As a result, contracted fuel flow portions are formed in the injection holes, so that the maximum flow velocity of fuel is increased at the injection hole outlet portions. Thus, a fuel injection valve for an internal combustion engine is provided, in which the atomization performance near the injection holes is effectively enhanced.
摘要:
A fluid mixer for mixing a first fluid and a second fluid includes an introducing component having a bore, a cylindrical component fitted into the bore of the introducing component and a mixing component having a conical recess and on which the introducing component and the cylindrical component are held. A first introducing flow path receives the first fluid and a first distributing flow path distributes the first fluid over the whole circumference of the cylindrical component. A second introducing flow path receives the second fluid. A second distributing flow path distributes the second fluid so that the first fluid and the second fluid are alternately arranged in an circumferential direction. A joining part joins together the first fluid and the second fluid fed with the fluids alternately arranged circumferentially.
