<p><P>PROBLEM TO BE SOLVED: To effectively control the flow of exhaust gas without deteriorating combustion in a cylinder when a cylinder injection internal combustion engine is operated in a compression stroke injection mode. <P>SOLUTION: When the flow of the exhaust gas is limited by an exhaust gas flow control valve 40 when the engine is operated in the compression stroke injection mode, the electronic control unit 60 of the cylinder injection internal combustion engine 1 reduces the overlapped period and the overlapped area of an intake valve 17 with an exhaust valve 18 by variable valve timing mechanisms 51 and 53. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
