<p><P>PROBLEM TO BE SOLVED: To provide a supercharging pressure control device that is easier to control than controlling using exhaust flow rate and has a equivalent accuracy to that of conventional devices. <P>SOLUTION: In a turbo supercharger having a turbine (6) provided in an exhaust passage, a compressor (7) provided in an intake passage, a waste gate (12) for opening/closing a passage bypassing the turbine (6), and a waste gate actuator (13) that can variably control the extent of opening/closing of the waste gate, a parameter that controls the waste gate actuator (13) is a function of an intake-air volume. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
