    • In an engine-brake assisting system comprising a hydraulic pressure producing unit, an exhaust valve driving unit and a hydraulic circuit member which are constructed as discrete elements, the hydraulic pressure producing unit produces a desired hydraulic pressure by rotating a camshaft disposed on a cylinder head to drive an engine-brake assisting cam. The generated hydraulic pressure is then supplied to an exhaust cam of the exhaust valve driving unit, which causes exhaust valves to open and close at a timing different from a valve opening and closing timing during a normal operation, thereby giving the engine a large brake force. With this arrangement, the reduction of overall size of the system and consequent reduction of overall height of an engine can be achieved.
    • 在包括作为分立元件构成的液压产生单元,排气阀驱动单元和液压回路构件的发动机制动辅助系统中,液压产生单元通过旋转设置在气缸盖上的凸轮轴产生期望的液压 驱动发动机制动辅助凸轮。 所产生的液压然后被提供给排气门驱动单元的排气凸轮,这在正常操作期间在不同于阀开启和关闭正时的定时使排气门打开和关闭,从而给发动机大的制动力 。 通过这种布置,可以实现系统的总体尺寸的减小和发动机的整体高度的降低。

    • A roof panel connected to a vehicle body through at least a pair of front pillars and a pair of rear pillars is provided with a large aperture on the roof with a front header and a pair of roof side rails. A rear window glass panel is fixed to the rear pillars and the rear header. A flexible top is contractible or expandable in a longitudinal direction of the vehicle and disposed so as to uncover or cover the roof aperture. When the flexible top closes the roof aperture, it is abutted at its front end portion with the front header, at its side end portions with the roof side rails, and at its rear end portion with the rear header. When the top is in a folded state, it is located in a second posture nearby the trunk lid. The top can be transferred up to its third posture in a position nearby a lower end portion of the rear window glass panel. Vertical movement of the top at least between the second and third postures can automatically be performed by a control unit in condition where the vehicle halts. The vertical movement of the top can be continued when the vehicle is shifted to its running state in the course of a transfer thereof between the second and third postures, thereby ensuring a transfer to the second posture or to the third posture.
    • 通过至少一对前柱和一对后支柱连接到车体的屋顶板在屋顶上设置有大的孔,其具有前集管和一对屋顶侧轨。 后窗玻璃面板固定在后支柱和后插头上。 柔性顶部在车辆的纵向可收缩或可膨胀,并且设置成露出或覆盖车顶孔。 当柔性顶部关闭屋顶孔时,它的前端部分与前集管,其侧端部与屋顶侧轨道抵接,并且在其后端部与后集管邻接。 当顶部处于折叠状态时,它位于行李箱盖附近的第二姿势中。 顶部可以在后窗玻璃板的下端部附近的位置被转移到第三姿势。 至少在第二和第三姿势之间的顶部的垂直运动可以在车辆停止的情况下由控制单元自动执行。 当车辆在第二和第三姿势之间的转移过程中车辆移动到其行驶状态时,可以继续顶部的垂直运动,从而确保转移到第二姿势或第三姿势。
