<p><P>PROBLEM TO BE SOLVED: To change only the driving timing of one of a pair of suction valves independently of the driving timing of the other suction valve. <P>SOLUTION: A variable valve system includes a rotational phase variable device 30 for changing only the rotational phase of one camshaft 10 of two cam shafts 10 and 20 and not changing that of the other camshaft 20, a first suction force transmission mechanism 40 for transmitting a rotational force of one cam shaft 10 to one suction valve 4 of a pair of suction valves 4 and 5 to drive the first suction valve 4, and a second suction force transmission mechanism 50 for transmitting a rotational force of the other cam shaft 20 to the other suction valve 5 of the pair of suction valves 4 and 5 to drive the second suction valve 5. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
