摘要： PROBLEM TO BE SOLVED: To solve such a trouble as the bearing part of a distributor is worn early at the time of driving the distributor directly in a rotational driving body (drive gear) to which large radial load is applied. SOLUTION: A discase 15 which rotatably supports a rotating shaft 10 is fitted between the case 1a of a distributor 1 and a gear case 6, the radial load of a drive gear 2 is received by the rotating shaft 10 and the discase 15, and only the rotational force of the rotating shaft 10 is transmitted to the shaft 9 of the distributor 1. No radial load is transmitted to the shaft 9, therefore, such a trouble as bearing parts 11, 12 which support the shaft 9 are worn early does not occur. The radial load is added only to the rotating shaft 10, therefore, the bearing parts 16, 17 of the rotating shaft 10 are worn. Even if any trouble occurs, no troubles occur to the distributor 1. It is thus necessary to replace only a discase 15, which is provided with the rotating shaft 10 and the bearing parts 16, 17, without replacing the distributor 1.

摘要： Eine Hochdruckpumpe hat ein elastisches Element (71), das in einer Dämpferkammer (67) zwischen einer ersten Membran (61) und einer zweiten Membran (64) angeordnet ist. Das elastische Element (71) ist mit beiden Membranen (61, 64) ständig in Kontakt, während die Hochdruckpumpe (10) betrieben wird. Wenn die Membrane (61, 64) infolge einer Resonanz in einer Situation weiter schwingen, in der eine Frequenz der Druckpulsation des Niederdruckkraftstoffs mit der Eigenfrequenz der Membrane (61, 64) in Übereinstimmung ist, dann beschränkt das elastische Element (71) das Verformen der Membrane (61, 64). Daher kann die Resonanz der ersten Membran (61) und der zweiten Membran (64) beschränkt werden.

摘要： Eine Kraftstoffeinspritzsteuerungsvorrichtung wird bei einer Kraftstoffeinspritzvorrichtung (10) angewendet, die Kraftstoff, der in einer Brennkraftmaschine zu verbrennen ist, durch einen Ventilöffnungsbetrieb eines Ventilkörpers (12) entsprechend einer elektromagnetischen Anziehungskraft, die durch eine Energieversorgung einer Spule (14) erzeugt wird, einspritzt. Die Kraftstoffeinspritzsteuerungsvorrichtung steuert einen Einspritzzustand der Kraftstoffeinspritzvorrichtung, indem ein Spulenstrom, der durch die Spule fließt, gesteuert wird. Die Kraftstoffeinspritzsteuerungsvorrichtung umfasst einen Vergrößerungssteuerungsabschnitt (S11, S14), der den Spulenstrom auf einen ersten Sollwert (Ihold1) vergrößert, einen Haltesteuerungsabschnitt (S11, S14, S15, S17), der den Spulenstrom, der durch den Vergrößerungssteuerungsabschnitt vergrößert wird, auf dem ersten Sollwert hält, und einen Änderungsabschnitt (S43, S44), der den ersten Sollwert entsprechend dem Betriebszustand der Brennkraftmaschine ändert.

Each injection hole group has a number of injection holes (10) penetrating a wall of the body section and connected to the guide hole to form a number of fuel openings through which a fuel is injected into a combustion chamber. A switch section (3) is displaceably arranged in the guide hole for opening/closing the fuel opening. The injection holes of each injection hole group are arranged adjacent to each other. Preferred Features: The body section is a jet and the switch section is designed as a needle.

摘要： PROBLEM TO BE SOLVED: To provide a resin intake manifold for an internal combustion engine, provided in the internal combustion engine having an exhaust gas recirculation device and supplying intake air to each cylinder.
SOLUTION: This resin intake manifold arranged in the internal combustion engine having a plurality of cylinders, and having communication portions 22a to 22d sectionally formed and communicating with the cylinders by mutually joining a resin upper member and a resin lower member, includes an exhaust gas introducing passage 15 interposed between joint surfaces of the upper member and lower member and extending along the joint surfaces. The exhaust gas introducing passage 15 includes an introducing port 25 for introducing exhaust gas into the exhaust gas introducing passage 15, lead-out ports 27a to 27d for leading out exhaust gas in the exhaust gas introducing passage 15 through the communication portions 22a to 22d, and an operating valve 32. An exhaust gas flow condition in the exhaust gas introducing passage 15 is controlled through open/close control over the operating valve 32, thereby equally discharging exhaust gas into each cylinder.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of internal-combustion engines that can prevent abrasion or wear of end-side connecting rod bearings and thus suppress vibration and noise without causing increases in weight and in friction loss. SOLUTION: An end-side crank journal 21a has an internal oil hole 27. Another oil hole 28 opens at one end onto one end of the oil hole 27 and at the other end onto the periphery of a crankpin 23. An end-side journal bearing 24a has an arcuately sectioned groove 29 cut along the internal surface of an upper bearing part 24U to open on an oil feed passage 25. The oil feed passage 25, oil holes 27 and 28 and groove 29 cooperate to feed lubricating oil to an end-side connecting rod bearing 26a without interruption. An intermittent lubricating means consists of the oil feed passage 25, and an oil hole passing through the crank arm that exists between a crank journal other than such end-side ones and the crankpin 23.
