An internal combustion engine characterized by being slidably inserted into a fitting hole of a member. (2) The utility model registration claim 1 is provided with a driving means for moving the movable member so as to project the movable member into the combustion chamber when the load is light and to pull the movable member into the insertion hole when the load is high. Internal combustion engine according to item 1. (3) the internal combustion engine has one intake valve;
The internal combustion engine according to claim 2, wherein the movable member is applied to a valve seat, an intake port, and a valve lifter insertion hole corresponding to the one intake valve. (4) the internal combustion engine has a plurality of intake valves;
3. The internal combustion engine according to claim 2, wherein the movable member is applied to a valve seat, an intake port, and a valve lifter insertion hole corresponding to at least one intake valve. (5) The internal combustion engine according to claim 4, wherein the movable member is made to protrude toward the combustion chamber by more than the valve lift when the load is light.
