摘要： A turbine housing assembly (20) includes a tubular piston (40) disposed in a bore of a turbine housing (32) and axially slidable between a closed position and an open position for blocking a nozzle (36) by an amount dependent on axial positioning of the piston. A bypass control member (52) is disposed in the turbine housing and is slidable between a no-bypass position closing a bypass passage and a open bypass opening the bypass passage (50). The piston is structured and arranged to slide relative to the bypass control member for a part of a full stroke of the piston from the closed position toward the open position thereof, and then to engage the bypass control member and cause the bypass control member to slide together with the piston as the piston further slides toward the open position thereof such that the bypass control member is moved toward the bypass position.

摘要： A method for controlling a variable-geometry turbine (24) that includes a variable-geometry mechanism that is movable between a fully closed position closing a relatively greater portion of the turbine nozzle and a fully open position closing a relatively smaller portion of the nozzle. The turbine (24) further comprises a waste gate (40) movable between a closed position and an open position in which some of the exhaust gas bypasses the turbine (24). At low engine speeds, turbocharger boost us regulated by regulating the position of the wastegate. At high engine speeds, the variable geometry is fully open and the wastegate is opened again. When at medium engine speeds, the variable-geometry mechanism is to be moved from its closed position toward its fully open position, the waste gate (40) is in an open position to cause a proportion of the exhaust gas to bypass the turbine (24) and thereby reduce the pressure of the exhaust gas in the chamber. While this reduced pressure of the exhaust gas is in effect, the variable-geometry mechanism is moved from the fully closed position toward the fully open position while simultaneously the waste gate begins to close.
摘要翻译：一种用于控制可变几何涡轮机（24）的方法，所述可变几何涡轮机（24）包括可变几何机构，所述可变几何机构可在关闭所述涡轮喷嘴的较大部分的完全关闭位置和闭合所述喷嘴的较小部分的完全打开位置之间移动。涡轮机（24）还包括可在闭合位置和打开位置之间移动的废气门（40），在该位置中，一些废气绕过涡轮机（24）。在低发动机转速下，涡轮增压器通过调节废气门的位置来提高我们的调节。在高发动机转速下，可变几何形状完全打开，废气门再次打开。当处于中等发动机速度时，可变几何机构将从其关闭位置移动到其完全打开位置，废物门40处于打开位置，以使一部分排气绕过涡轮机（24）），从而降低室内的废气的压力。虽然废气的这种减小的压力是有效的，但是可变几何机构从完全关闭位置移动到完全打开位置，同时废气门开始关闭。
