    Abstract: An exhaust purification system is provided that can continuously maintain a NOx purification rate to be high while suppressing the occurrence of ammonia slip. The exhaust purification system includes a slip determination portion 34 that determines the occurrence of ammonia slip based on an output value NH3CONS of an ammonia sensor 26. A reference injection amount calculating portion 31 calculates a reference injection amount GUREA—BS based on a parameter correlating to an operating state of an engine. A switching injection amount calculating portion 32 decreases in amount a urea injection amount GUREA by setting a switching injection amount GUREA—SW to a negative value in response to having determined that ammonia slip has occurred, and increases in amount the injection amount GUREA by setting the switching injection amount GUREA—SW to a positive value in response to a storage amount estimated value STUREA having fallen below a predetermined switch storage amount STUREA—SW.

    Abstract: An ECU controls to inject a small amount of fuel in an expansion/exhaust stroke under constraint of the minimum fuel injection capability of an injector at the time of warming-up of a catalyst. The ECU controls injection of fuel in expansion/exhaust strokes (expansion/exhaust stroke injection) at the time of warming-up of a catalyst. Fuel injection control is performed so that when temperature of the catalyst becomes higher than a predetermined temperature, fuel injection in the expansion/exhaust strokes is performed for a period of a predetermined ratio in a selected cycle period. The expansion/exhaust stroke injection is not performed in the other period. By effectively utilizing oxygen absorbed on the catalyst, while suppressing slip HC, the activation time of the catalyst can be shortened.

    Abstract: An optimum control parameter in control of an internal combustion engine and the like is searched. In a plurality of search cycles, a control parameter that maximizes an output of an object to be controlled which shows an output realized by a given control parameter is searched using control parameters. The control parameters are provided at each search cycle by a predetermined algorithm. A periodic function of a predetermined period and a correction value obtained in a previous search cycle are added to the control parameters to obtain an input parameters to the object. An output obtained from the object with the input parameters is multiplied by the periodic function to obtain a correction value for correcting the control parameters such that the search converges.

    Abstract: A device and a method for determining the trouble of a cylinder pressure sensor without increasing cost calculates the cylinder pressure of an internal combustion engine based on an output from the cylinder sensor installed in the engine and calculates a drift parameter indicating the drift amount of the cylinder pressure based on the cylinder pressure. When the drift parameter is not within a specified range, the device determines that the cylinder pressure sensor is defective. The specified range can be set based on the behavior of the cylinder pressure. A correction factor is obtained according to the operating state of the engine, and the drift parameter is corrected with the correction factor. A specified search signal is superimposed on the output from the cylinder pressure sensor. The cylinder pressure is calculated based on the output from the cylinder pressure sensor on which the search signal was superimposed.
