<P>PROBLEM TO BE SOLVED: To prevent a non-desired quantity of EGR gas from being introduced via an EGR passage during impulse supercharging. <P>SOLUTION: This internal combustion engine 10 is provided with: an intake control valve 38 provided in an intake air passage 16 at an upstream side of an intake valve 32; an intake control valve control means controlling the intake control valve 38 opening one time and closing one time per one intake stroke for carrying out impulse supercharging; an EGR valve 66 provided in the EGR passage 62 carrying out communication between the exhaust gas passage 42 and the intake air passage 16; and an EGR valve control means closing the EGR valve 66 when the intake control valve control means controls the intake control valve 38 to carry out impulse supercharging. The intake control valve control means controls closing timing of the intake control valve 38 to adjust internal EGR gas quantity when the intake control valve 38 is controlled to carry out impulse supercharging. Desired quantity of internal EGR gas is thereby introduced. <P>COPYRIGHT: (C)2009,JPO&INPIT |
