Abstract:
PROBLEM TO BE SOLVED: To realize both Otto cycle and a miller cycle at an internal combustion engine while an opening or closing structure for an intake valve is made as simple as possible.SOLUTION: This invention relates to an internal combustion engine operated in such a way that when a lock part 60 is set to a non-lock position, an engaging part 50 arranged at a cam shaft 20 is pushed against an advanced side end part 31A of an idling allowable part 31 at an intake cam 30 by a driving rotational force of a cam shaft 20 until an intake cam 30 fully opens an intake valve, and upon full open of the intake valve by the intake cam 30, the advanced side end part 31A of the idling allowable part 31 at the intake cam 30 is moved away from the engaging part 50 arranged at the cam shaft 20 by a spring force of the intake valve, and the intake cam 30 is moved in idling state only by an idling angle in a cam shaft rotating direction in respect to the cam shaft 20 until a counter-advancing end part 31B of the idling allowable part 31 is pushed against the engaging part 50 arranged at the cam shaft 20.SELECTED DRAWING: Figure 11
