Method and system for controlling an internal combustion engine |
摘要 |
Methods and systems for controlling an internal combustion engine are provided. One example method may include closing an intake valve later during a cylinder cycle than a timing with which an amount of air inducted into a cylinder from an air intake passage would be maximized, and earlier during the cylinder cycle as a desired amount of air to be inducted into the cylinder increases, while an engine is operating at a given engine speed. The method may further include closing the intake valve earlier during a cylinder cycle as the engine speed increases when the desired amount of air to be inducted into the cylinder is at a maximum. |
