Abstract (en)
[origin: EP2085591A1] A control system for an internal combustion engine (1) having an air supply passage (7) for supplying air to the engine (1). The air supply passage (7) includes a first and a second branch passages respectively communicating with a combustion chamber of the engine (1). The engine (1) further includes an exhaust gas recirculation passage for recirculating a part of exhaust gases discharged from the combustion chamber to the first branch passage (7A), a first control valve (26) for controlling an amount of the recirculated exhaust gases, and a second control valve (22) disposed upstream of the first and the second branch passages for opening and closing the air supply passage (7). An operation speed of the second control valve (22) is reduced when closing the second control valve (22) during a valve opening operation of the first control valve (26). The recirculated exhaust gases are thereby prevented from flowing into the second passage where a swirl control valve is disposed, thereby avoiding sticking of the swirl control valve.
