Method for controlling an inlet-adjustment mechanism for a turbocharger compressor

The invention relates to a method for controlling an inlet-adjustment mechanism for a turbocharger compressor. A method for controlling an inlet-adjustment mechanism in an air inlet for a compressor so as to switch the mechanism between open and closed positions for adjusting a flow area of the inlet. The method includes an algorithm for determining when the inlet-adjustment mechanism is in a failure mode. In accordance with the method, when the operating point on the compressor map is on the high-flow side of a threshold line at which the inlet-adjustment mechanism is switched from one position to the other, a measured speed or pressure ratio is compared to a theoretical value for the speed or pressure ratio based on a compressor map for the open position of the mechanism. If the measuredvalue differs from the theoretical value by more than a predetermined tolerance, a failure mode is indicated. 本发明涉及用于控制涡轮增压器压缩机的入口调节机构的方法。一种用于控制压缩机的空气入口中的入口调节机构的方法，以便在打开位置和闭合位置之间切换该机构，用于调节入口的流动面积。该方法包括用于确定入口调节机构何时处于故障模式的算法。根
