摘要： Provided is a direct spray fuel injector including a bundle of opening/closing valves, wherein the bundle of opening/closing valves includes: a valve needle that is disposed within a valve housing that constitutes an exterior of the direct spray fuel injector in a lengthwise direction and that opens and closes a spray hole opened to one side of the valve housing; an electromagnetic coil that is installed at a side opposite to the spray hole of the valve needle and causes a spray hole opening/closing operation of the valve needle to be performed; an armature that is coaxially mounted on an outer circumferential surface of the valve needle to be slidable in an axial direction so as to be positioned between the valve needle and the electromagnetic coil; and a pressurizing spring that is installed to pressurize the valve needle toward the spray hole and causes the valve needle to close the spray hole in normal times, and the bundle of opening/closing valves is configured to pressurize the valve needle by the armature so that bounce generated when the valve needle in an open state approaches the spray hole so as to close the spray hole is able to be attenuated. The structure of a buffer spring that suppresses bounce generated in the valve needle when a valve is closed is simplified so that the number of components of the bundle of opening/closing valves and the number of assembling processes of the direct spray fuel injector can be reduced and manufacturing efficiency and economic feasibility of the direct spray fuel injector can be improved.

摘要： In the disclosed electromagnetic fuel-injection valve: a non-magnetic or weakly magnetic guide bush (19) is affixed at the inner periphery of an immobile core (6); the front end of the guide bush (19) protrudes from the suction surface (6a) of the immobile core (6); during excitation of a coil (37), by means of a mobile core (16) being caused to contact the front end of the guide bush (19), the opening boundary of a valve body (15) is defined, and an air gap (g) is formed between the immobile core (6) and the mobile core (16); and a sliding member (20) that is slidably borne at the inner peripheral surface of the guide bush (19) is provided to a valve assembly (V). As a result, a structure-simple electromagnetic fuel injection valve is provided wherein the opening/closing postures of the valve body can be effectively stabilized, and moreover at the time of demagnetization of the coil, valve closing responsiveness can be favorably obtained.

摘要： When diffusion combustion is performed, a squash flow (24) flows from a squash area (22) into a cavity portion (12b) during the compression stroke, the squish flow (24) is generated to form in the cavity portion (12b) a longitudinal vortex flow, in which a flow at an portion in the cylinder, has a velocity component directed inward in a radial direction of the cylinder and a flow at a lower portion in the cylinder has a velocity component directed outward in a radial direction of the cylinder. Fuel is injected from nozzle holes (13a) at injector (13), which is disposed top face the center portion of the cavity portion to to an outer peripheral portion of the cavity portion (12b), and a ratio between the diameter or the cavity and the diameter of a cylinder bore falls within a range of 0.66 to 0.76.

摘要： A fuel injector apparatus and method for use in a fuel injection system of an internal combustion engine that includes a body (20), a valve seat (60), closure member (40), and an orifice plate (70). The valve seat comprises the intersection of two angled surfaces before assembly of the fuel injector. During assembly of the fuel injector, a member presses against the edge of the sealing surface of the valve seat to create an oblique third sealing surface or sealing band that is coined into the valve seat. The sealing band provides an improved seal between the valve closure member (40) and the valve seat (60) which operates to prevent leakages of fuel in the fuel injector.
