摘要：
The invention relates to a variable valve type internal combustion engine and a control method for controlling said engine in which operation modes of plural intake valves (7a) and (7b) provided in one cylinder are independently changed according to the drive region of the internal combustion engine (100). In the low air amount region, the intake airflow is controlled only with intake valve (7a) which operates in the low air amount region and the other intake valve (7b) is operated in the medium and high air amount regions.
