摘要： An air-fuel ratio control system for an internal combustion engine has a first air-fuel ratio sensor arranged in an exhaust passage at a location upstream of a catalyst and a second air-fuel ratio sensor arranged in the exhaust passage at a location downstream of the catalyst. In response to an output from the first air-fuel ratio sensor, an air-fuel ratio correction coefficient is calculated for correcting an amount of fuel supplied to the engine in a manner such that an air-fuel ratio of a mixture supplied to the engine is converged to a desired air-fuel ratio. In response to an output from the second air-fuel ratio sensor, a desired air-fuel ratio correction amount is calculated for correcting the desired air-fuel ratio. A learned value of the desired air-fuel ratio correction amount is calculated, and the desired air-fuel ratio is corrected. Calculation of the learned value of the desired air-fuel ratio correction amount is permitted depending on a ratio between a time period over which the output from the second air-fuel ratio sensor is on a richer side with respect to a predetermined reference value and a time period over which the output from the second air-fuel ratio sensor is on a leaner side with respect to the predetermined reference value.

摘要： An ignition timing control system controls ignition timing of spark plugs of an internal combustion engine associated with a plurality of changeover devices, changeover of an operative state of each of which has influence upon output torque of the engine. Operating conditions of the engine are detected. A basic ignition timing advance value is calculated based on results of detection of the operating conditions of the engine. A changeover of the operative state of each of the changeover devices is detected. A correction value for correcting the basic ignition timing advance value for suppressing the engine torque is calculated, in response to results of detection of the changeover of the operative state of each of the changeover devices. The largest one of a plurality of the correction values calculated is selected to a final correction value to be used for correcting the basic ignition timing advance value, when changeovers of the operative states of at least two of the changeover devices are detected substantially at the same time.

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： A first cutoff valve 24 and a second cutoff valve 41 are closed in a state in which an internal combustion engine 1 is stopped, and a reducing amount of a pressure P0 in a high pressure passageway 11 after the passage of a predetermined decision time T0 and a reducing amount of a pressure P2 in a low pressure passageway 12 after the passage of a predetermined decision time T2 are measured. When the reducing amount of the first pressure P0 is equal to or larger than a predetermined reducing amount &Dgr;P0, it is decided that a leakage is generated in the high pressure passageway 11. When the reducing amount of the second pressure P2 is equal to or larger than a predetermined reducing amount &Dgr;P2, it is decided that a leakage is generated in the low pressure passageway 12.

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.
