摘要： An ignition timing control system for an internal combustion engine, which is capable of ensuring both stability of control in a steady operating condition of the engine, and an excellent follow-up property of a controlled variable to a target value in a transient operating condition of the engine, even when the controlled variable contains a lot of high-frequency noise components. In the ignition timing control system, a maximum pressure angle-calculating section calculates a maximum pressure angle based on an in-cylinder pressure and a crank angle position. A target angle-calculating section calculates a target angle. A maximum pressure angle controller calculates a maximum pressure angle correction term with a control algorithm to which is applied a sliding mode control algorithm, using a value obtained by performing ε-filtering on a switching function, such that the maximum pressure angle converges to the target angle. The ignition timing is calculated by adding corrected ignition timing to the value.

摘要： An air-fuel ratio control system for an internal combustion engine, which is capable of accurately estimating an exhaust gas state parameter according to the properties of fuel, thereby making it possible to properly control the air-fuel ratio of a mixture. The air-fuel ratio control system 1 estimates an exhaust gas state parameter indicative of a state of exhaust gases, as an estimated exhaust gas state parameter (AF13 NN) by inputting a detected combustion state parameter (DCADLYIG) indicative of a combustion state of the mixture in the engine 3, and detected operating state parameters (NE, TW, PBA, IGLOG, TOUT) indicative of operating states of the engine 3, to a neural network (NN) configured as a network to which are input the combustion state parameter (DCADLYIG) and the operating state parameters (NE, TW, PBA, IGLOG, TOUT), and in which the exhaust gas state parameter is used as a teacher signal (step 1), and controls the air-fuel ratio based on the estimated exhaust gas state parameter (AF_NN) (steps 3, 4, and 24 to 28).

摘要： An exhaust gas purifying apparatus for an internal combustion engine is provided for simultaneously realizing sufficient recovery of the adsorbing capability of an adsorbent and limitation to an increase in exhaust resistance. The exhaust gas purifying apparatus for an internal combustion engine comprises a flow path switching valve for switching an exhaust gas flow path to a bypass exhaust passage or to a main exhaust passage, three-way catalysts, and an HC adsorbent arranged in the bypass exhaust passage for adsorbing hydrocarbons in exhaust gases and fully desorbing the adsorbed hydrocarbons when it is heated to a full desorption temperature or higher. A troidal passage of the main exhaust passage completely surrounds a portion of the bypass exhaust passage in which the HC adsorbent is arranged. A ratio S1/S2 of the cross-sectional area S2 of the troidal passage to the cross-sectional area of a flow-in passage is set in a range from 1.0 at which the exhaust resistance begins gradually decreasing as the ratio S2/S1 increases to 3.0 at which the HC adsorbent can be heated to the full desorption temperature or higher.

摘要： While the amount of intake air introduced into an internal combustion engine is being increased by an intake air quantity control unit, an ignition timing control unit manipulates the ignition timing of the internal combustion engine to converge the rotational speed of the internal combustion engine to a target rotational speed according to a feedback control process (PI control process). The ignition timing control unit has a function to vary the feedback gain of the feedback control process depending on the ignition timing, such that the feedback gain is smaller as the ignition timing being manipulated is more retarded.
