摘要： From the relationship between the pressure change in the evaporative purge system during purge cutting and the valve opening pressure of an air intake valve, respective valve opening pressures of a tank internal pressure regulating valve and a back-purge valve, each opening and closing a vapor passage, are found. As an actual valve opening pressure is found, the diagnosis can be effected under the circumstances where the tank internal pressure regulating valve or the back-purge valve is securely closed, whereby defect diagnosis can be effected as frequently as possible without setting a diagnosable pressure range such as that required conventionally.

摘要： A pressure control device allows evaporated fuel evaporated in an fuel tank of an engine to be discharged to a canister during the engine running state. The canister absorbs the evaporated fuel. The pressure control device continues to allow evaporated fuel in the fuel tank to be discharged to the canister after the engine stops until a predetermined period has elapsed. The pressure control device allows evaporated fuel in the fuel tank to be discharged to the canister while a pressure in the fuel tank is higher than a first predetermined pressure after the predetermined period has elapsed in the engine stopped state. On the other hand, the pressure control device prevents evaporated fuel in the fuel tank from being discharged to the canister while a pressure in the fuel tank is lower than the first predetermined pressure after the predetermined period has elapsed in the engine stopped state.

摘要： A NOx amount capable of being absorbed by a criteria catalyst as a boundary between degradation and normality is supplied to a NOx storage reduction catalyst and thereafter, a reducer amount corresponding to the NOx amount is supplied by a rich spike operation. Degradation of the NOx catalyst is determined based upon the output of the NOx sensor at this time. Since the degradation of the NOx catalyst is determined only by a magnitude of the NOx sensor output, the degradation diagnosis can be performed with high precision. While the catalyst is normal, the excessive reducers are not supplied and therefore, deterioration of the fuel consumption can be prevented.

摘要翻译： 通过标准催化剂作为降解和正常之间的边界吸收的NOx量被提供给NOx储存还原催化剂，此后通过富峰操作提供与NOx量对应的还原剂量。 此时NOx催化剂的降解是基于NOx传感器的输出而确定的。 由于NOx催化剂的劣化仅由NOx传感器输出的大小决定，所以可以高精度地进行劣化诊断。 当催化剂正常时，不提供过量的还原剂，因此可以防止燃料消耗的劣化。

摘要： An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention obtains an output Vabyfs of an air-fuel ratio sensor disposed at a portion downstream of an exhaust gas aggregated portion of an exhaust gas passage, and obtains a second-order differential value d2AF (a change rate of a change rate of a detected air-fuel ratio abyfs) of a detected air-fuel ratio abyfs represented by the air-fuel ratio sensor output Vabyfs. The imbalance determining apparatus determines that an air-fuel ratio imbalance state among cylinders is occurring when a detected air-fuel ratio second-order differential corresponding value (for example, a second-order differential value d2AF per se) obtained in accordance with the second-order differential value d2AF is larger than a first threshold value.

摘要： A reduction in the accuracy of a failure determination of a filter due to a reduction in the detection accuracy of a PM sensor is suppressed. In order to achieve this, provision is made for a filter, an NOx selective reduction catalyst at the downstream side of the filter, a supply device for supplying a reducing agent to the NOx selective reduction catalyst, a PM sensor for detecting an amount of particulate matter in an exhaust gas at the downstream side of the NOx selective reduction catalyst, and a supply decrease part that makes an amount of supply of the reducing agent smaller in cases where at least one of the following conditions is satisfied than in cases where any of the conditions is not satisfied, wherein the conditions include: a condition in which the temperature of the NOx selective reduction catalyst is equal to or less than a threshold value; a condition in which the temperature of the exhaust gas is equal to or less than a threshold value; a condition in which the flow rate of the exhaust gas is equal to or larger than a threshold value; and a condition in which the amount of adsorption of the reducing agent in the NOx selective reduction catalyst is equal to or larger than a threshold value.

摘要： The fact that “with respect to a process in which the output value of a downstream air-fuel ratio sensor (sensor output value) is inverted from the minimum output value to the maximum output value during execution of an active control, the local maximum and minimum values of the secondary differential value of the sensor output value is widely affected by the size of the response delay of the downstream air-fuel ratio sensor and the size of the degree of the degradation of the three-way catalyst” is utilized. By preliminarily acquiring and memorizing, as maps, these relations obtained through an experiment, and applying the “local maximum and minimum values of the secondary differential value of the sensor output value” calculated from the transition of the sensor output value acquired during execution of the active control to the maps, the response delay (time constant) of the downstream air-fuel ratio sensor is acquired.

摘要： In a fuel injection system of an internal combustion engine in which a first fuel, which has a property to inhibit the adsorption of exhaust gas components by an exhaust gas purification catalyst, and the second fuel, which has a property not to inhibit the adsorption of the exhaust gas components by the exhaust gas purification catalyst, are able to be selectively used, the present invention has a task to decrease an amount of consumption of the second fuel in a suitable manner. In order to solve this task, the fuel injection system of an internal combustion engine according the present invention is constructed such that the second fuel is first supplied to the internal combustion engine when the exhaust gas purification catalyst is in a cold state, and a change from the second fuel to the first fuel is then made before the exhaust gas purification catalyst subsequently rises in temperature to an activation temperature thereof.
