摘要： An object of the present invention is to provide an internal combustion engine control device that, when an abnormal combustion is detected, is capable of not only exercising control to suppress the occurrence of the abnormal combustion, but also exercising catalyst temperature control. The control device acquires the temperature of a catalyst disposed in an exhaust path of an internal combustion engine, and detects an abnormal combustion that has occurred in a combustion chamber of the internal combustion engine. The control device includes gas control means, which controls the amount of intake gas flowing into the combustion chamber and the temperature of exhaust gas flowing into the catalyst, and fuel injection amount control means, which controls the amount of fuel injected into the combustion chamber. The control device also includes abnormal combustion inhibition mode selection means that chooses a first mode, a second mode, or a third mode in accordance with the catalyst temperature when the abnormal combustion is detected. The first mode causes the gas control means to suppress the occurrence of the abnormal combustion while raising the catalyst temperature. The second mode causes the fuel injection amount control means to suppress the occurrence of the abnormal combustion while inhibiting an increase in the catalyst temperature. The third mode causes the gas control means and the fuel injection amount control means to suppress the occurrence of the abnormal combustion.

摘要： A control apparatus (100) of the present invention is a control apparatus for for an internal combustion engine (10) equipped with an idling stop mechanism (30) and a supercharger (14). The control apparatus is provided with: a controlling device (30) which is configured to detect atmospheric pressure and to change a threshold value of a parameter which allows idling stop processing to be performed by the idling stop mechanism, to a side on which the idling stop processing is not allowed, as the detected atmospheric pressure has a lower value, in order to suppress an excessive increase in temperature of a catalyst (16).

摘要： In a system that selects a large-cam (16) as a driving cam at a time of a start of an engine, when an engine stop request is output, it is determined whether there is a small-cam cylinder for which a small-cam (14) is selected as the driving cam. In a case where it is determined that there is a small-cam cylinder, a switching command for switching the driving cam from the small-cam (14) to the large-cam (16) is output. When an engine start request is output, the above determination is performed again. In a case where it is determined that there is a small-cam cylinder, the switching command is output to all solenoid actuators (24) again. In addition, the drive of the fuel injector (36) is suspended until the switching operation of the driving cam is completed for all cylinders.
