INTAKE CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To appropriately control a level difference in supercharging pressure when switching an intake passage in an intake control device of an internal combustion engine containing two lines of intake passages. SOLUTION: An intake control device of an internal combustion engine contains two lines of intake passages to perform impulse charge. A first and second switching valves are respectively arranged in confluent positions on an upstream side and downstream side in two lines of intake passages. A control means for executing control to the first and second switching valves so as to make temporal opening changes of the first and second switching valves substantially identical to each other when switching a passage through which intake air flows to one of the two lines of intake passages. Thus, a level difference in supercharging pressure occurring when switching two lines of intake passages can be appropriately controlled. COPYRIGHT: (C)2010,JPO&INPIT
