    摘要: A high pressure fuel supply pump comprises a cylinder, the upper part of which is exposed to the outside of a head cover that is a part of the engine housing, and is fixed to the head cover by means of bolts, not shown. The remaining portion of the high pressure fuel supply pump is received in an accommodation hole of the head cover. A pump cam 111 is mounted to a valve camshaft for driving a suction/exhaust valve and drives the high pressure fuel supply pump. The use of an exclusive shaft for pump driving only, a bearing member therefor, and the like is rendered unnecessary, which enables a reduction in the number of parts employed. Further, since the timing with which the pressurized fuel is discharged is controlled through the operation of a solenoid valve, the precision with which fuel injection is controlled is improved.

    摘要: An apparatus and method for applying constant pressure to a plurality of pressure demanding mechanisms is disclosed. The apparatus includes a common rail, a plurality of pressure demanding mechanisms, a pressure supply source, and a plurality of branching paths. The lengths of the pressure supply path Lp, the pressure propagation path in the common rail, Lc, and the pressure branching paths, Li, are chosen so as to satisfy the following formulae, which leads to reductions in pressure fluctuations:(2n+0.5)Lp.ltoreq.Lc.ltoreq.(2n+1.5)Lp(2n+1.5)Lp.ltoreq.Li.ltoreq.(2n+2.5)Lp, where (n=0, 1, 2, . . .).

    摘要: A fuel injection valve of a diesel engine, comprising a valve body including a concave conical surface in the tip portion of the valve body, and fuel injection holes extending from the concave surface to the outside of the valve body, and a needle valve movable in the valve body and including a cylindrical shaft portion, a first conical surface adjacent to the shaft portion and having a conical angle smaller than that of the concave surface, the lower edge of the first conical surface defining a contact line separably contacting with the concave surface, a second conical surface adjacent to the first surface and having a conical angle substantially equal to that of the concave surface, a third conical surface adjacent to the second surface and having a conical angle greater than that of the concave surface. In case of a smaller lift amount of the needle valve, the fuel flow speed flowing into the fuel injection hole is fast and the atomized fuel injection divergence angle from the injection hole is great, thereby producing active producing mixing of the fuel with the air and enhancing the ignition feature, while in case of a greater lift amount, the fuel flow speed is slow and the atomized fuel injection divergence angle from the injection hole is small, thereby increasing the fuel flow reach and producing an active mixing of the fuel with the air by virtue of the kinetic energy of the atomized fuel flow.

    摘要: A noise control device eliminates a possibility that a noise arriving at a control point is increased as compared to a case where noise control is not performed and has a reduced circuit scale. The device includes a controlling noise detector for detecting a given noise to output a controlling noise signal, a controlling filter section for signal-processing the controlling noise signal, by using a preset fixed filter coefficient, to output a control signal, and a control speaker for reducing the given noise, by emitting toward the control point a control sound based on the control signal. The device also includes a noise determination section for determining whether the given noise is a noise corresponding to the fixed filter coefficient, and an output control section for stopping output of the control signal from the controlling filter section when the given noise does not correspond.

    摘要: A diffracted sound reduction device includes: a reproduction speaker that outputs reproduced sound having properties indicated by an input signal; control speakers each of which reproduces corresponding one of control signals, the diffracted sound being a part of the reproduced sound and arriving at corresponding one of the control points except the control point at the listener's position; and control filters each of which filters the input signal to generate corresponding one of the control signals. Each of the control points faces a corresponding speaker from among the reproduction speaker and the control speakers. Each of the control filters generates the corresponding one of the control signals so that a sound pressure of the diffracted sound at corresponding one of the control points is lower than a sound pressure of direct sound that is a part of the reproduced sound which arrives at the control point of the listener's position.
