Abstract: A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

Abstract: An engine controller includes an ignition timing control unit and a rich imbalance determining unit. The rich imbalance determining unit designates one of multiple cylinders as a subject cylinder for determination and executes lean active control that commands a smaller amount of fuel injection for the subject cylinder than for the other cylinders.

The ignition timing control unit executes an advancement limiting process that limits advancement of the ignition timing by the knock control during the execution of the lean active control.
