Device for controlling the operation of an internal combustion engine

摘要

The present disclosure refers a method and device for controlling the operation of an internal combustion engine. The internal combustion engine is provided with at least one piston/cylinder unit having at least one intake valve, and is operating in a first load range and in a second load range, the second load range being higher than the first load range. The method comprises at least the step of, in the second load range of the internal combustion engine, closing the intake valve in a range of 20° to 45° before a BDC of the piston, according to a Miller cycle, and switching off the operation according to the Miller cycle at least during a part of a load increase within the second load range.
