    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： A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage adsorbing unburned HC in exhaust gas generated by the engine. Based on the assumption that the degradation of the adsorbent made from zeolite progresses or advances depending on its temperature, the temperature is detected and if it exceeds a predetermined temperature, an index indicative of the degree of degradation progress is determined based on a surplus exceeding the predetermined temperature. The index is accumulated to be compared with a threshold value and the adsorbent is discriminated to be degraded when the accumulated index exceeds the threshold value, thereby enabling to discriminate the adsorbent degradation accurately with a simple configuration.

    摘要： A control system for an internal combustion engine according to one aspect of the invention calculates a total amount of evaporative fuel purged from a canister based on dynamic characteristics and concentration of purged gas. The system calculates an amount of evaporative fuel supplied to the combustion chamber of the engine based on the total amount of evaporative fuel and depending on dynamic characteristics of the purged gas. Then, the system determines a required amount of fuel to be injected by a fuel injection valve based on the amount of evaporative fuel supplied to the combustion chamber. A control system according to another aspect of the invention calculates an amount of fuel to be injected by the injection valve and the ratio of the amount of fuel to be injected to the amount of fuel to be purged from the canister based on operating conditions of the engine, and based on this ratio, controls the purge control valve and at the same time decreases the amount of fuel to be injected, while setting a limit to this ratio for maintaining the linear relationship of the valve opening period of the fuel injection valve and the fuel injection amount.

    摘要： An air-fuel ratio control system for an internal combustion engine calculates an amount of fuel to be supplied to the engine in response to the rotational speed of the engine and a parameter indicative of load on the engine, and an amount of fuel injected into an intake passage and adhering to the inner surface of the intake passage, based upon a direct supply ratio and a carry-off ratio. A feedback correction value is set to such a value that an air-fuel ratio in exhaust gases from the engine becomes equal to a desired value, and the amount of fuel calculated as above is corrected by the direct supply ratio, the carry-off ratio, and the feedback correction value set as above. A control speed at which the feedback correction value is corrected is set based upon at least one of the direct supply ratio and the carry-off ratio.
