<p><P>PROBLEM TO BE SOLVED: To provide an air bypass valve control device for an internal combustion engine with a supercharger, for controlling an air bypass valve provided therein to properly handle a waist gate valve driving mechanism, when malfunctioned. <P>SOLUTION: The internal combustion engine with the supercharger has the supercharger 10 consisting of a turbine arranged in an exhaust passage and a compressor arranged in an intake passage, the waist gate valve 21 mounted in a bypass line 20 for bypassing the turbine of the supercharger in the exhaust passage, and the waist gate valve driving mechanism 23 for driving the waist gate valve 21. The air bypass valve control device for the internal combustion engine with the supercharger comprises an air bypass valve mechanism 31 for communicating/shutting off an air bypass line 30 bypassing the compressor of the supercharger 10 in the intake passage and a control means 50 for controlling the air bypass valve mechanism 31. When determining that the waist gate valve driving mechanism 23 is malfunctioned, the control means 50 controls the air bypass valve mechanism 31 to put the air bypass line 30 into a communicated condition. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
