    • An internal combustion engine includes a turbocharger, a variable valve gear, an A/F sensor in an exhaust passage, A/F feedback control means, and scavenge A/F control means. The variable valve gear drives intake and exhaust valves, and can drive with a valve open characteristic with valve overlap. The A/F feedback control means performs feedback correction of a fuel injection amount based on an A/F sensor output, and acquires a learning value of information relating to A/F control from a feedback correction amount. The scavenge A/F control means carries out A/F control by a value learned during an operation of the engine with non-scavenge valve open characteristic, when the variable valve gear is operated with the scavenge valve open characteristic. The scavenge valve open characteristic has a valve overlap amount of such a degree that blow-by of intake air occurs in an intake stroke during a turbocharger operation.
    • 内燃机包括涡轮增压器,可变气门齿轮,排气通道中的A / F传感器,A / F反馈控制​​装置和清扫A / F控制装置。 可变阀齿轮驱动进气阀和排气阀,并可以用阀重叠的阀打开特性驱动。 A / F反馈控制​​装置基于A / F传感器输出执行燃料喷射量的反馈校正,并且从反馈校正量获取与A / F控制相关的信息的学习值。 清扫A / F控制装置,当采用清扫阀打开特性操作可变气门齿轮时,通过在非清扫阀打开特性的发动机的操作期间学习的值来执行A / F控制。 清扫阀打开特性具有在涡轮增压器运转期间在进气冲程中发生进气窜气的程度的阀重叠量。

    • A ball joint is disclosed having a socket, a ball received by the socket and a stud extending outwardly from the ball. A ball seat member is received in the socket and has a soft portion with an inner spherical surface which covers the portion of the ball at the side opposite to the stud. The soft portion is axially compressed by a cap closing an opening in the socket opposite to the stud, while expanding radially outward to be penetrated by linear projections formed in a hard portion of the ball seat member. Further, a gap remains between the soft portion after it has expanded radially outwardly and the inner cylindrical surface of the hard portion of the ball seat member so that the soft portion of the ball seat member contacts the hard portion of the ball seat member only at the linear projections.
    • 公开了一种球窝接头,其具有插座,由插座接收的球和从球向外延伸的螺柱。 球座构件容纳在插座中并且具有柔软的部分,内部球形表面覆盖与螺柱相对的一侧的球的该部分。 柔软部分被盖子轴向地压缩,盖帽与插座相对地闭合插座中的开口,同时径向向外扩张以被形成在球座构件的硬部分中的线性突起穿透。 此外,在柔软部分已经径向向外延伸并且球座构件的硬部分的内圆柱表面之间留有间隙,使得球座构件的软部分仅在球座构件的硬部分接触 线性投影。
