    Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine that can prevent occurrence of a turbo lag even if the internal combustion engine has a supercharger not having an electric motor.SOLUTION: When an idle stop condition is decided as established, the value detected by a temperature sensor is decided whether it is lower than a determination value (step 110). When the value detected by the temperature sensor is decided lower than the determination value, the value detected by a pressure sensor is decided whether it is higher than the determination value or not (step 120). When the value detected by the temperature sensor is decided as the determination value or higher, a part of engine cylinders is stopped (step 130). When the value detected by the pressure sensor is decided higher than the determination value in step 120, a part of the engine cylinders is stopped (step 130). If not, all the cylinders of the engine 10 are stopped (step 140).

    Abstract: PROBLEM TO BE SOLVED: To solve a problem that the acceleration performance at engine acceleration degrades when a fuel amount increase rate is set to 1 (0% increase) in most of the engine operation region including a supercharging area.SOLUTION: A device calculates a first fuel amount increase rate F1 corresponding to a current intake air amount (S11) and a second fuel amount increase rate F2 corresponding to an output mixture ration (S12), and determines whether or not an internal combustion engine is under an acceleration operation state (S14) on the basis of an intake air amount detected by an air flow meter and engine rotation speed. When the internal combustion engine is determined not to be under an acceleration operation state, the first fuel amount increase rate F1 is set to a fuel amount increase rate F0 (S17). When the engine internal combustion engine is determined to be under an acceleration operation state, the larger one of the first fuel amount increase rate F1 and second fuel amount increase rate F2 is set as the fuel amount increase rate F0 (S15-S17). Fuel injection control is executed on the basis of the set fuel amount increase rate F0.

    Abstract: PROBLEM TO BE SOLVED: To reduce a fuel injection amount of pre-stage injection required for optimizing a state in a cylinder 11a, while improving controllability of main combustion by optimizing the temperature and a pressure state in the cylinder 11a when starting main injection, in a control device of a diesel engine 1 with a supercharger.SOLUTION: When an engine body 1 is within a particular operating range with a low engine speed and a partial engine load and in a low temperature state where a cylinder temperature at a compression stroke end is lower than a predetermined temperature, while a superchrging amount by a supercharger 62 is set to a supercharging amount equal to or above a predeteremined amount larger than a superchrging amount in a high temperature state where the cylinder temperature is the predetermined temperature or above, at least within the particular operating range, an injection control means (PCM10) performs a main injection where a fuel injection starts at or before a top dead center of the compression stroke to cause main combustion mainly including diffusion combustion and performs a pre-stage injection where the fuel injection is performed at least once with timing prior to the main injection to cause pre-stage combustion before the main combustion starts.
