    • An engine control device for detecting misfire of an engine. Based on a detected crank angle of the engine, an angular velocity at a first crank angle at which the engine speed is close to a minimum within one combustion cycle of each cylinder is calculated as a pre-combustion angular velocity, and an angular velocity at a second crank angle at which the engine speed is close to a maximum within the same combustion cycle is calculated as a post-combustion angular velocity. An amount of rotation variation caused between the first and second crank angles is calculated based on the pre-combustion and post-combustion angular velocities of the same combustion cycle, and is compared with a predetermined misfire criterion to determine whether or not misfire has occurred. When misfire is detected, a required operation is performed, for example, a warning lamp is turned on or the fuel supply quantity is increased.
    • 一种用于检测发动机失火的发动机控制装置。 基于发动机的检测到的曲柄角,计算在每个气缸的一个燃烧循环内发动机转速接近最小值的第一曲柄角处的角速度作为预燃角速度和 在相同的燃烧循环中发动机转速接近最大值的第二曲柄角被计算为后燃烧角速度。 基于相同燃烧循环的燃烧前燃烧角和后燃烧角速度来计算在第一和第二曲柄角之间产生的旋转变化量,并与预定的失火准则进行比较,以确定是否发生失火。 当检测到失火时,执行所需的操作,例如警告灯打开或燃料供应量增加。

    • In order to provide a metal gasket suitable for use for a flange made of synthetic resin, the metal gasket disposed between a resin flange and an aluminium flange is composed of two elastic metal plates, on each of which a half bead is formed, and which are superposed on each other to be jointed so that half beads are directed opposite to each other. Since bending in a state, where the gasket is tightened, can be suppressed to an extremely small value at a same level in the case where the flanges are tightened without gasket, it is possible to remove worsening in flatness (planarity) of the resin flange.
    • 为了提供适合用于合成树脂制的凸缘的金属垫片,设置在树脂凸缘和铝凸缘之间的金属垫片由两个弹性金属板构成,每个弹性金属板上形成有一个半珠,并且 彼此重合以使得半珠彼此相对。由于在垫圈被紧固的状态下的弯曲可以在法兰盘的情况下以相同的水平被抑制到极小的值 在没有垫圈的情况下拧紧,可以消除树脂凸缘的平坦度(平坦度)的恶化。

    • In order to improve a sealing structure of a joint for three members, in which the three members butt against each other and a joint portion has a T-shape, in the sealing structure of a joint for three members, in which the three members, i.e. a first, a second and a third member, butt against each other and a joint portion has a T-shape, at least one plate-shaped gasket, in which rubber layers are formed on two surfaces of a metal plate, is disposed between surfaces to be jointed where the second and the third member are butted against the first member. An opening is formed in the plate-shaped gasket at a portion, which is opposite to a T-shaped portion, and filled with paste-like liquid gasket sealing the T-shaped portion.

    • An internal combustion engine includes a cylinder head having a pair of upright intake ports formed therein on opposite sides of a plug hole extending along a cylinder axis, and each intake port has an upstream-side upright part extending from the top face of the cylinder head along the cylinder axis and a downstream-side slanting part having an intake opening communicating with a combustion chamber on one side of an imaginary plane containing the cylinder axis. An upper opening of each intake port opening in the top face of the cylinder head has a peripheral edge extending along the peripheral edge of an upper opening of the plug hole, and the peripheral edge of the upstream-side upright part extends along the outer surface of a lash adjuster. When viewed in vertical section along the imaginary plane, the upstream-side upright part extends obliquely downward from the top face of the cylinder head in a direction away from the lash adjuster, and the downstream-side slanting part approaches the plug hole with decrease in distance to the combustion chamber and then extends parallel to the plug hole. The downstream-side slanting part, when viewed in vertical section perpendicular to the imaginary plane, extends away from the cylinder axis with decrease in distance to the intake opening. With the intake ports having the above overall shape and sectional shape, each intake port can be given a required cross-sectional area without increasing the dimensions of the engine, and makes it possible to form a proper intake air flow inside the combustion chamber.
