Abstract
An ECUis provided to an engineincluding a TCVthat changes a tumble flow generated inside a cylinder and being configured to be capable of securing a cooling of a cylinder blockand suppressing an occurrence of a cooling loss in a cylinder head. The ECUincludes a control unit that feedback-controls the TCVbased on a primary blow-off voltage Vi so that a flow velocity of air flowing along a surface on the cylinder headside becomes greater than a flow velocity of air flowing along a surface on the pistonside in a case where a flow velocity of air flowing along a surface on one of the cylinder headside and the pistonside becomes greater than a flow velocity of air flowing along a surface on another side in the cylinder.
