Filed: 2009-03-02
Abstract: <P>PROBLEM TO BE SOLVED: To avoid an interference of an intake valve with a piston without limiting a target value of each variable mechanism.  <P>SOLUTION: A control device includes two variable valve mechanisms which make valve lift characteristics of an intake valve variable, and a variable valve mechanism for changing a top dead center position of piston. An actuator of each mechanism is drive-controlled normally toward a target value set depending on engine operating condition. The control device detects actual operating position of each actuator for each predetermined arithmetic interval (S11), and predicts a minimum distance ΔPB between piston and valve in the vicinity of an exhaust top dead center point (S12), in consideration of the actual working position and its operating speed and operating direction. The control device determines whether the ΔPB is smaller than a predetermined threshold value ΔPBs (S13). If smaller, the control device limits an operation of the actuator that operates in a direction in which the distance between piston and valve becomes small.  <P>COPYRIGHT: (C)2010,JPO&INPIT
