摘要： PROBLEM TO BE SOLVED: To improve measuring accuracy of oxygen storage capacity by excluding deterioration influence of a sensor behind catalyst. SOLUTION: Active air-fuel ratio control for switching an air-fuel ratio on the upstream side of a catalyst between rich/lean is executed in response to overturn of output Vr of the sensor behind catalyst which detects an air-fuel ratio on the downstream side of the catalyst. The oxygen storage capacity of the catalyst is measured in every overturn period of the output Vr of the sensor behind catalyst. The oxygen storage capacity is measured during periods t11 to t12 in which the output Vr of the sensor behind catalyst is normal in the overturn periods. The overturn periods of the output of the sensor behind catalyst are excluded from the measurement periods to exclude the deterioration influence of the sensor behind catalyst.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply control device for an internal combustion engine capable of suppressing the deterioration in emission after high temperature restarting at highland.
SOLUTION: An electronic control unit ECU determines whether it is high temperature restarting time or not based on the output of a water temperature sensor 29 and an intake air temperature sensor 19, and decides an initial increasing amount value based on the output of an atmospheric pressure sensor 21 when it is the high temperature restarting time. The initial increasing amount value is made to be large in inverse proportion to the atmospheric pressure. The electronic control unit ECU decides an air-fuel ratio feedback control starting time based on the atmospheric pressure. The air-fuel ratio feedback control starting time is made to be short in proportion to the atmospheric pressure. The electronic control unit ECU determines whether rich determination is conducted or not based on the output of an oxygen sensor 25, and starts air-fuel ratio feedback control after the air-fuel ratio feedback control starting time is elapsed since starting, when the rich determination is not conducted.

摘要： PROBLEM TO BE SOLVED: To improve exhaust emission by most suitably controlling supply of secondary air and increase of fuel quantity at a time of cold start. SOLUTION: An air pump 41 is operated at a same time with cold start, a secondary air control valve 42 is opened to supply secondary air to an exhaust port 6. Fuel quantity is increased if exhaust gas temperature TG in an exhaust port is higher than threshold TGa, and secondary air is supplied but fuel quantity is not increased if exhaust gas temperature TG in the exhaust port is lower than threshold TGa. Consequently, deterioration of exhaust emission due to supply of un-burnt fuel is prevented. If secondary air is supplied to the exhaust port without fuel quantity increase, temperature of exhaust gas drops and air fuel ratio goes under a lean condition. Though low temperature exhaust gas under lean condition reaches a catalyst 23, purification rate does not drop since the catalyst is activated more easily under the lean condition.

摘要翻译：要解决的问题：通过最适当地控制二次空气的供给和在冷启动时的燃料量的增加来改善废气排放。
解决方案：一个空气泵41在冷启动的同时工作，一个二次空气控制阀42打开以向排气口6供应二次空气。如果排气口中的废气温度TG 高于阈值TGa，并且如果排气口中的排气温度TG低于阈值TGa，则二次空气被供给但燃料量不增加。因此，防止由于供给未燃烧燃料而导致的废气排放的劣化。如果在不增加燃料量的情况下向排气口供给二次空气，则排气温度下降，空燃比处于稀薄状态。虽然在贫条件下的低温废气达到催化剂23，但由于在稀薄条件下催化剂更容易活化，所以净化速率不会下降。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the rotational speed of an internal combustion engine from being excessively raced without being affected by the change of rotating behavior after the start of the internal combustion engine in the controller of the internal combustion engine. SOLUTION: Until the rotating peak of the rotating speed of the internal combustion engine is detected after the start of the internal combustion engine, control parameters (for example, igniting timing) different from intake flow rate related to the output of the internal combustion engine are set when the output of the internal combustion engine is lowered less than parameter values in idle (for the ignition timing, spark timing is delayed). After the rotating peak is detected, the control parameters are adjusted to parameter values in idle. COPYRIGHT: (C)2005,JPO&NCIPI
