PROBLEM TO BE SOLVED: To provide a variable valve device of an internal combustion engine which prevents temperature on a combustion chamber wall surface (cylinder wall surface) from lowering and retains the temperature on the combustion chamber wall surface with exhaust gas in the variable valve device of the internal combustion engine.SOLUTION: A control means (24) changes a lift amount such that a lift amount of at least one intake valve (11A) becomes larger than that of another intake valve (11B) and changes the lift amounts of the intake valves (11A/11B) when an exhaust circulation device (25) circulates exhaust gas to the intake valves (11A/11B) side. |
