    • An auxiliary valve actuating mechanism of an engine is provided. The engine includes a conventional valve actuating mechanism (200) and an auxiliary valve actuating mechanism (2002). The auxiliary valve actuating mechanism (2002) includes an auxiliary cam (2302), an auxiliary rocker-arm shaft (2052), an auxiliary rocker arm (2102), an eccentric rocker-arm shaft bush (188) and a shaft bush actuating mechanism (100). The eccentric rocker-arm shaft bush (188) is provided inside the shaft hole of the auxiliary rocker arm (2102). The auxiliary rocker-arm shaft (2052) is provided inside the eccentric rocker-arm shaft bush (188). The shaft center of the auxiliary rocker-arm shaft (2052) is biased from the shaft center of the eccentric rocker-arm shaft bush (188). One end of the auxiliary rocker arm (2102) constitutes a motion pair with an auxiliary cam (2302), and the other end is above the valve (300). The shaft bush actuating mechanism (100) actuates the eccentric rocker-arm shaft bush (188) to rotate between an operating position and a non-operating position. At the non-operating position, the rocking center line of the auxiliary rocker arm (2102) is away from the valve (300), and the auxiliary rocker arm (2102) is separated from the valve; and at the operating position, the rocking center line of the auxiliary rocker arm (2102) is close to the valve, the auxiliary rocker arm contacts with the valve, and the movement of the auxiliary cam is transmitted to the valve to generate the motion of the auxiliary valve. The auxiliary valve actuating mechanism is simple in structure, and easy to mount.
    • 提供了一种发动机的辅助阀致动机构。 发动机包括常规的阀致动机构(200)和辅助阀致动机构(2002)。 辅助阀致动机构(2002)包括辅助凸轮(2302),辅助摇臂轴(2052),辅助摇臂(2102),偏心摇臂轴衬(188)和轴套驱动机构 (100)。 偏心摇臂轴衬(188)设置在辅助摇臂(2102)的轴孔的内部。 辅助摇臂轴(2052)设置在偏心摇臂轴衬(188)的内部。 辅助摇臂轴(2052)的轴心从偏心摇臂轴衬(188)的轴心偏置。 辅助摇臂(2102)的一端构成与辅助凸轮(2302)的运动对,另一端位于阀(300)的上方。 轴套驱动机构(100)致动偏心摇臂轴衬(188)以在操作位置和非操作位置之间旋转。 在非操作位置,辅助摇臂(2102)的摇摆中心线远离阀(300),辅助摇臂(2102)与阀分离; 并且在操作位置,辅助摇臂(2102)的摆动中心线靠近阀,辅助摇臂与阀接触,并且辅助凸轮的运动传递到阀,以产生运动 辅助阀。 辅助阀致动机构结构简单,安装方便。

    • An exhaust gas pressure regulator ( 100) for an engine (10) is provided. The exhaust gas pressure regulator comprises an exhaust gas duct (1 10) delimiting an exhaust gas flow path (106) and a regulating member (120), which is moveable in a first direction in the exhaust gas duct (1 10) between a first end position, in which the exhaust gas flow path (106) is open for exhaust gas throughflow, and a second end position, in which the regulating member (120) at least substantially closes the exhaust gas flow path ( 106) for exhaust gas throughflow, wherein said regulating member ( 120) and said exhaust gas duct ( 1 10) are configured for defining an annular gap ( 170) when the regulating member (120) is positioned in the second end position for allowing exhaust gas to flow through said exhaust gas pressure regulator (100).
    • 一种用于发动机的排气压力调节器包括:排气管,其限定排气流路和调节构件,所述排气管可在排气管道中的第一方向上移动,所述第一端位置在排气流路为 开放排气通过流动,第二端位置,其中调节构件至少基本上封闭用于废气通过的排气流动路径,其中限制构件和排气管道构造成在调节构件时限定环形间隙 构件位于第二终端位置,以允许废气流过废气压力调节器。
