摘要： PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine capable of suppressing the reduction of controllability when controlling a temperature of cooling water to a target value during feedback control of a flow rate control valve.
SOLUTION: During the feedback control of the flow rate control valve 7, lower limit guard is performed concerning a degree of opening of the valve 7. Consequently, the adjustment of degree of opening of the flow rate control valve 7 is not performed in an opening degree region in the vicinity of full closing where change of a water temperature at an engine exit becomes excessively great or little for change of degree of opening. Moreover, when the tendency of the water temperature at the engine exit is inverted between ascent tendency and descent tendency during the feedback control, a degree of opening of the flow rate control valve 7 is changed by a skip amount S so that water temperature at the engine exit approaches the target value.

SOLUTION: An engine cooling device circulates a cooling water to control cooling of an engine 1 according to operation condition. The device comprises a water temperature sensor 31 which detects a cooling water temperature THW1, a flow-rate adjusting valve 8 which adjusts the flow-rate of circulated cooling water, and an electronic control device (ECU) 30 which controls it.

The ECU 30 opens/closes fast the flow-rate adjusting valve 8 so that the cooling water temperature approaches the first control range when the cooling water temperature THW1 is within the second control range, while it opens/closes slowly the flow-rate adjusting valve 8 so that the cooling water temperature THW1 approaches the no-control range when the cooling water temperature THW1 is within the first control range. It keeps the current open degree of the flow-control adjusting valve 8 when the cooling water temperature THW1 is within the no-control range.

摘要： PROBLEM TO BE SOLVED: To provide an ignition timing controller of an internal combustion engine capable of suppressing the erroneous learning of a knock determination level resulting from the occurrence of knocking during learning when the knock determination level is learned. SOLUTION: An electronic control device 30 determines whether the occurrence of knocking is present or not through a comparison between the knock determination level learned on the basis of the background noise of a knock sensor 33 in a knock determination period and the output signal of the knock sensor 33. Based on the results of the determination, the electronic control device performs a knocking determination control to correct ignition timing. When the time of occurrence of vibration noise due to the operation of an injector 22 is changed in the knock determination period by the change of the fuel injection timing by the re-circulation of exhaust gas, knocking determination is prohibited until the learning of the knock determination level performed when the state of engine operation is changed is completed, and the ignition timing is corrected to a retard angle side more than a timing set by the knocking determination control.
