    摘要: A plasma ignition device is provided with a plasma ignition plug having an insulation member to insulate a center electrode from a ground electrode, and electric power supply circuits to apply high voltages to the plasma ignition plug. The plasma ignition device activates the gas in a discharge space of the insulation member into the plasma of a high temperature and a high pressure by the high voltage applied between the center electrode and the ground electrode and injects the same into an internal combustion engine. The electric power supply circuits are connected to the center electrode as an anode and to the ground electrode as a cathode.

    摘要: The present invention makes it possible to obtain good characteristics of forming sprays of fuel jetted through a plurality of injection ports of a fuel injection valve with respect to separation of sprays in different directions, atomization, jetting angles and penetrating force.Fuel jetted through the injection ports of the fuel injection valve is jetted in separate jets from a plurality of fuel flow separating holes of a sleeve nozzle. On the other hand, band-like assist air flows are jetted in a two-dimensional manner from slit-like air holes opened on the opposite sides of the fuel flow separating holes to impinge obliquely against the jetted fuel. Atomization of fuel jetted through the plurality of fuel flow separating holes is thereby promoted and fuel sprays are accurately separated and supplied independently in two directions toward two intake valves while the directions of jets from the injection ports of the fuel injection valve are maintained, thus injecting and supplying fuel. As a result, an amount of fuel impinging directly against walls which separates and forms two intake ports is reduced and an amount of atomized sprayed fuel directly entering a combustion chamber from the intake ports is therefore increased, thereby improving combustion characteristics.

    摘要: A fuel feed apparatus of an internal combustion engine is provided having a fuel passage serving to guide fuel in a predetermined direction, and an assist air passage serving to collide assist air against the fuel. The apparatus includes an inner member formed therein with the fuel passage extending from one end surface to another end surface thereof. An outer member is provided in surrounding relation to the inner member and forms the assist air passage between the inner member and the outer member. The outer member has at least one penetrating hole penetrating therethrough defining an inlet opening of the assist air passage. The air passage extends from the penetrating hole in a direction along fuel injection and has an outlet opening opened to an outlet side of the fuel passage. The outer member is joined to the inner member at an outer periphery of the one end surface of the inner member.

    摘要: A nozzle holder includes a support portion, which supports a downstream end surface of a planar wall of an injection hole plate. The injection hole plate provided with injection holes is welded to one of the valve body and the nozzle holder. The planar wall may be curved and may be thus convex in an upstream direction toward a downstream end opening such that the planar wall is urged against a peripheral edge of the downstream end opening of the valve body. The planar wall may include a reinforcing rib located radially outward of the injection hole.

    摘要: In an injection hole plate of a fuel injection device, injection holes are arranged about a circle. Fuel injected from the injection holes forms a flat sector-shaped spray. The intervals between adjacent injection holes are approximately equal to each other, while the diameters of the injection holes are equal to each other. An injection hole is positioned on an imaginary plane, which contains the central axis of the sector-shaped spray along the injection direction and is orthogonal or approximately orthogonal to the sector-shaped spray. The injection holes, away from the imaginary plane in this order, are symmetric with respect to the line of intersection of the injection hole plate and the imaginary plane. The farther each injection hole is away from the imaginary plane, the larger an angle of gradient of the injection hole with respect to the imaginary plane becomes.

    摘要: A fuel injection nozzle is configured and dimensional with a flat flow passage just above the outlet orifice(s). When the abutting portion of a needle valve moves away from the valve seat, fuel flows are directed uniformly toward the orifice from around its periphery so as to collide with each other just above each orifice inlet. Atomized fuel is then injected to the engine from the orifice. The internal energy of the fuel flows can more effectively be utilized in the collisions to more finely atomize the fuel and to maintain the ability to provide a highly direction output injection spray.
