CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, capable of extending, in an internal combustion engine provided with an exhaust gas recirculation device, the period for recirculating exhaust gas through an exhaust gas recirculation passage while suppressing freezing of condensed water in an intake passage and deterioration of burning state in a combustion chamber. SOLUTION: Cooling time control is executed in cooling of an engine. In the cooling time control, a tumble control valve (TCV) 30 is controlled, when recirculating EGR gas through an EGR passage 21, so that the passage sectional area (Scold) of an intake passage 13 is smaller than the passage sectional area (Swarm) of the intake passage 13 in engine warming time (Scold
