    • In an automotive engine exhaust pipe having a main flow passage and a bypass flow passage, the exhaust gas flows through the bypass flow passage having an heater-provided catalyst when an engine starts. After a main catalyst reaches a catalytic activation temperature, a switching valve switches the exhaust gas to flow through the main flow passage. The main shaft is divided into a driven shaft inserted into a bearing hole and a driving shaft inserted into another bearing hole, and therefore, a total length thereof in an axial direction is shorter than a length of the main shaft without having segments. Therefore, even though the driven shaft and the driving shaft are deformed into the arch shape, a deformation amount thereof is reduced so that inner peripheries of the bearing holes are not rubbed against the shafts. Since the driving shaft is smaller in diameter than the driven shaft, even though a cross section of the driving shaft is elliptically strained, the inner periphery of the bearing hole is not rubbed against the driving shaft. As a result, since a clearance between the driving shaft and the bearing hole can be narrowed, the exhaust gas from the clearance can be prevented from leaking.
    • 在具有主流路和旁通流路的汽车发动机排气管中,当发动机起动时,排气通过具有加热器的催化剂的旁通流路流动。 在主催化剂达到催化活化温度之后,切换阀切换排气流过主流道。 主轴分为插入轴承孔的从动轴和插入另一个轴承孔的驱动轴,因此其轴向的总长度短于不具有段的主轴的长度。 因此,即使从动轴和驱动轴变形为拱形,其变形量也减小,使得轴承孔的内周不会摩擦轴。 由于驱动轴的直径小于从动轴的直径,即使驱动轴的横截面是椭圆形的,轴承孔的内周也不会摩擦驱动轴。 结果,由于驱动轴和轴承孔之间的间隙可以变窄,所以能够防止来自间隙的废气泄漏。

    • A resonance detection device is provided for detecting resonance in an exhaust passage of an automotive vehicle. The detection device employs a temperature sensor in combination with an arrangement which enables the sensor to be exposed to a flow of exhaust gas the temperature of which is different from the temperature of the bulk of the flow, when resonance occurs. In given embodiments the arrangement takes the form different diameter conduits and/or vessels, while others it takes the form of a heat exchange device which either heats or cools the gases, and which is disposed proximate the temperature sensor. When no resonance occurs in the passage, the output of the temperature sensor remains stable. When resonance occurs the fluid flow characteristics in the passage change in a manner wherein the gas which has been either heated or cooled by the heat exchange device is induced to flow against the temperature sensor. The sensed temperature change can be used to control a valve via which the resonance characteristics of the passage are modified and via which resonance is attenuated.
    • 提供一种谐振检测装置,用于检测机动车辆的排气通路中的共振。 检测装置采用温度传感器与能够使传感器暴露于当发生共振时其温度不同于流体体积的温度的排气流的布置的结构。 在给定的实施例中,该装置采用不同直径的导管和/或容器的形式,而另一些则采用热交换装置的形式,其可以加热或冷却气体,并且设置在温度传感器附近。 当通道中没有发生共振时,温度传感器的输出保持稳定。 当共振发生时,通道中的流体流动特性以其中被热交换装置加热或冷却的气体被诱导相对于温度传感器流动的方式改变。 感测到的温度变化可以用于控制通道的谐振特性经过该阀的修正并且共振被衰减。
