    摘要: In a fuel injection valve having a nozzle hole plate wherein a nozzle hole is formed, the nozzle hole is formed with a flow path cross-section having an oval shape that has long axes and short axes, and the nozzle hole is formed having a tapered shape in which a flow path sectional area becomes larger from an entry-side open end portion toward an exit-side open end portion. The nozzle hole is formed such that a second angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in an oblique section along the short axes of the entry-side open end portion and the exit-side open end portion, is greater than a first angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in a longitudinal section along the long axes of the entry-side open end portion and the exit-side open end portion.

    摘要: The invention relates to a control apparatus for controlling a solenoid valve that functions to displace one of an intake valve or an exhaust valve of an internal combustion engine. The object of the invention is to adjust, when a valve element connected to the solenoid valve is displaced between a valve-open position and a valve-closed position, the magnitude of an electromagnetic force displacing the valve element, to a controlled value based on a pressure acting on the valve element. The solenoid valve displaces the valve element (40) by a cooperation of resilient forces of an upper spring (104) and a lower spring (106) and electromagnetic forces of an upper coil (98) and a lower coil (100). In the control apparatus, a pressure acting on the valve element (40) is detected directly or indirectly. When the valve element is displaced from one of the valve-open position and the valve-closed position to the other position, the magnitude of an electromagnetic force to displace the valve element (40) to the other position is adjusted to a controlled value based on the valve-element pressure detected.

    摘要: A cooling structure for an internal combustion engine is such that a bottom surface (51) of a cylinder head (5) is recessed so as to form recessed coolant passage (55B) that communicates with an intake-side water jacket part (22a) formed in a cylinder block, and surround periphery of an injector fixing part (53). An upper edge of a water jacket spacer (3) disposed in a block-side water jacket is provided with projections (34) projecting toward the recessed coolant passage (55B) so as to direct at least part of the coolant flowing through the intake-side water jacket part (22a) toward the recessed coolant passage (55B). With this, it is possible to suppress decrease in flow rate of the coolant due to disturbance caused to the coolant flow flowing along the periphery of the injector fixing part (53), to thereby provide a sufficient cooling performance for an injector.

    摘要: A cylinder head (100) in an internal combustion engine includes a cylinder head main body (101) in which a plurality of combustion chambers (10a to 10d) is arranged and a pipe member (110, 120) that extends along a direction in which the combustion chambers (10a to 10d) are arranged, through which a refrigerant flows, and which is embedded in the cylinder head main body (101). The pipe member (110, 120) is provided with a curved portion (113a to 113d and 123a to 123d) that is curved and the curved portion (113a to 113d and 123a to 123d) is provided with a throttle region (115a to 115d and 125a to 125d) in which a sectional area is partially reduced.

    摘要: An electromagnetically driven valve (10) includes a driven valve (14) having a stem (12) extending in a prescribed direction and an umbrella-shaped portion (13) provided at a tip end of the stem (12) and opening/closing an intake/exhaust port, a lower disc (20) and an upper disc (30) having one ends (22, 32) coupled to the stem (12) and the other ends (23, 33) supported by a disc support base (51) so as to allow free oscillation of the disc respectively and oscillating around the other ends (23, 33) so as to cause the driven valve (14) to carry out reciprocating motion in the prescribed direction, a lash adjuster (16) provided in the stem (12), and a guide ring (45) guiding the lash adjuster (16) along the prescribed direction. The lash adjuster (16) contracts and expands in the prescribed direction and accommodates displacement of the stem (12) produced in a direction orthogonal to the prescribed direction as a result of reciprocating motion of the driven valve (14). With such a structure, the driven valve carries out smooth reciprocating motion.
