    • A steering column assembly includes a steering column having an upper steering column tube and a lower steering column tube which are telescopically connected at their lower and upper portions respectively, a stationary bracket fixed to a vehicle body and an energy absorption bracket fixed to the stationary bracket. The energy absorption bracket fixedly receives the upper steering column tube which extends therethrough. The energy absorption bracket gets plastically deformed in response to an impact load exceeding a predetermined value to allow the upper steering column tube to displace downward with respect to the lower steering column tube. The impact load is applied to the energy absorption bracket through the upper steering column tube in the direction along the axis of the steering column. The applied impact load is absorbed through the plastic deformation of the energy absorption bracket.
    • 转向柱组件包括转向柱,该转向柱具有分别在其下部和上部可伸缩地连接的上转向柱管和下转向柱管,固定到车体的固定支架和固定到固定支架的能量吸收支架 。 能量吸收支架固定地容纳延伸穿过的上转向柱管。 能量吸收支架响应于超过预定值的冲击载荷而塑性变形,以允许上转向柱管相对于下转向柱管向下移位。 冲击载荷通过上转向柱管沿转向柱轴线的方向施加到能量吸收支架上。 施加的冲击载荷通过能量吸收支架的塑性变形吸收。

    • The present invention provides a malfunction diagnostic apparatus for an evaporated fuel purge system in an internal combustion engine, capable of detecting abnormalities such as looseness or clogging in the purge line between a purge valve and an engine intake passage. An electric pump 14 is turned on when a purge valve 5 is in a closed state and a selector valve 20 is in an open state. After the lapse of a given time period Tref, a load-current initial value I1 of the electric pump 14 is detected at the moment switching the selector valve 20 to a closed state. After the lapse of a given time period Tpump, the purge valve 5 is switched to an open state, and a load-current final value at the moment after the lapse of a given time period Tpurge. As in the curve A, when a load current final value I2A is equal to or less than the load current initial value I1, it is determined that the gaseous communication state in the purge line between the purge valve 5 and the intake passage is normal. On the other hand, as in the curves B and C, when load current final values I2B and I2C are greater than the load current initial value I1, it is determined that the gaseous communication state is abnormal. In case of abnormality, when the difference I2B−I1 therebetween is less than a gaseous-communication-state determination threshold fT1 as in the curve B, it is determined that the purge line is in an open-air state. If the difference I2C−I1 is equal to or greater than the gaseous-communication-state determination threshold fT1 as in the curve C, it is determined that the purge line is in a clogging state.
    • 本发明提供一种用于内燃机中的蒸发燃料吹扫系统的故障诊断装置,其能够检测在净化阀和发动机进气通道之间的净化管线中的松动或堵塞的异常。 当清洗阀5处于关闭状态并且选择阀20处于打开状态时,电动泵14接通。 在经过了给定时间段Tref之后,在将选择阀20切换到关闭状态的瞬间,检测到电动泵14的负载电流初始值I1。 在经过给定时间段Tpump之后,清洗阀5切换到打开状态,并且在经过给定时间段Tpurge之后的时刻的负载电流最终值。 如曲线A所示,当负载电流最终值I2A等于或小于负载电流初始值I1时,确定净化阀5和进气通道之间的净化管线中的气体连通状态正常。 另一方面,如曲线B和C所示,当负载电流最终值I2B和I2C大于负载电流初始值I1时,确定气体连通状态异常。 在异常的情况下,如果曲线B中的差异I2B-I1小于气体连通状态判定阈值fT1,则判断为净化线处于露天状态。 如果差异I2C-I1等于或大于气体通信状态判定阈值fT1,如曲线C那样,确定清除线处于堵塞状态。
