摘要： PROBLEM TO BE SOLVED: To properly cool a temperature control section using the heat absorption of a heat storing material at the timing when one wants to cool the temperature control section in a vehicle.SOLUTION: The heat storing material 7 housed in a reactor 6 of the heat control device is in the hydrated condition after warming is carried out using the heat control device. The inside of the reactor 6 is hermetically sealed, and the pressure inside of the reactor 6 is raised toward a target pressure Pt under this condition, thereby a cooling standby condition is attained, and the cooling standby condition is maintained. The heat storing material 7 can be prevented from being dehydrated or absorbing heat by receiving heat from the respective branches 2a of a collected exhaust pipe 2 because the heat storing material is hardly dehydrated from the heat storing material 7 when the heat storing material 7 housed in the reactor 6 receives heat under the cooling standby condition. The closed sealing of the inside of the reactor 6 is released when one wants to cool a catalyst 4 using the heat control device that is to cool the catalyst 4 using the heat absorption of the heat storing material 7 under the cooling standby condition.

摘要： PROBLEM TO BE SOLVED: To suppress wrong diagnoses by improving diagnostic accuracy.SOLUTION: The device executes an active air-fuel ratio control for alternatively switching an air-fuel ratio in upstream side of catalysts into lean control or rich control. After a sensor output reaches a threshold after catalyst and, as the same time, the lean control and the rich control are switched, when a post-catalyst sensor output is about to exceed a predetermined reference value at the arrival of a pre-catalyst air-fuel ratio at a stoichi, the device gives feedback correction to the threshold so that a difference between a post-catalyst sensor output upon reaching the stoichi and the reference value is released. The device determines whether the catalyst is normal or not based on the threshold when the difference is released.

摘要： PROBLEM TO BE SOLVED: To provide an air-fuel ratio control device of an internal combustion engine capable of reducing the discharged amount of NOx into the atmosphere when heating a three-way conversion catalyst device quickly to a catalyst activation temperature immediately after starting the engine.

摘要： PROBLEM TO BE SOLVED: To accurately determine whether catalyst is deteriorated or not irrespective of a flow rate of exhaust gas. SOLUTION: Whether the exhaust gas purifying catalyst 5 arranged in the gas exhaust passage 3 of an engine 1 is deteriorated or not, is determined by detecting reduction of O 2 storage function of the catalyst. When detecting the deterioration, exhaust gas having a rich air-fuel ratio and exhaust gas having a lean air-fuel ratio are alternately supplied to the catalyst to obtain an amount of oxygen occlusion of the catalyst based on timing at which the air-fuel ratio of the exhaust gas passing through the catalyst after switching the air-fuel ratios is changed by following the air-fuel ratio of flowing-in exhaust gas and detect reduction of the O 2 storage function. At this time, the air-fuel ratio of the exhaust gas having the rich air-fuel ratio and the exhaust gas having the lean air-fuel ratio is set to approach a theoretical air-fuel ratio, the larger the flow rate of exhaust is, to prevent inferred error of amount of oxygen occlusion occurring when flow rate of exhaust gas is large, and to determine the deterioration of the catalyst accurately irrespective of the flow rate of exhaust gas.

摘要： PROBLEM TO BE SOLVED: To accurately determine deterioration of a catalyst without calculating oxygen occlusion capacity of the catalyst. SOLUTION: A target air-fuel ratio is varied in a short period (step 104). When an integrated suction air amount egasam is determined as being larger than a predetermined value egasam 0 (step 106), it is determined whether average oxygen sensor output gaoxsav in the predetermined time is smaller than a reference value gaoxsav 0 or not, that is, whether the air-fuel ratio on the catalyst downstream side is lean fuel or not (step 108). When it is determined in the step 108 that the average oxygen sensor output gaoxsav is smaller than the reference value gaoxsav 0, that is, when it is determined that the air-fuel ratio on the catalyst downstream side is lean fuel, it is determined that the catalyst is deteriorated.

摘要： PROBLEM TO BE SOLVED: To provide an air-fuel ratio control system for an internal combustion engine, which prevents an air-fuel ratio from being set to be richer due to air-fuel ratio feedback control and reaction of catalyst, when the output value of a downstream air-fuel ratio sensor becomes rich when the engine enters a transient state, for example.SOLUTION: The air-fuel ratio control system feedback controls the air-fuel ratio so that the gas flowing into the catalyst 43 becomes a lean air-fuel ratio when the output value Voxs of the downstream air-fuel ratio sensor 56 reaches a rich determination threshold, and so that the catalyst inflow gas becomes a rich air-fuel ratio when the output value Voxs becomes equal to or below the lean determination threshold. When the upstream air-fuel ratio becomes equal to or below a predetermined value and the maximum output value Voxs of the downstream air-fuel ratio sensor 56 falls within a certain range, it is predicted that the output value Voxs of the downstream air-fuel ratio sensor 56 will drop before the catalyst 43 enters an over-oxygen state, and the lean determination threshold for determining the over-oxygen state is made smaller than the normal value.
