摘要： An ejector system controls the idle speed of an internal combustion engine by controlling an electric throttle valve system that adjusts the flow-rate of the intake air to be supplied to the internal combustion engine, and includes an ejector which generates a negative pressure of which the absolute value is larger than the absolute value of a negative pressure to be introduced from an intake manifold, a vacuum control valve which causes the ejector to operate or causes the ejector to stop operating, and an ECU that controls the vacuum switching valve. With the ejector system, even if the ejector is caused to operate or caused to stop operating, it is possible to appropriately suppress fluctuations in the idle speed, and appropriately obtain a negative pressure.

摘要： A secondary air supplying apparatus of the present invention comprises a secondary air supplying device for supplying secondary air to upstream of an emission purifying device in an exhaust system of an internal combustion engine, a coolant temperature sensor for detecting a temperature of a coolant for the engine, an intake air temperature sensor for detecting a temperature of intake air, a supply controller for actuating the secondary air supplying device in accordance with a predetermined secondary air supply condition, and a summing unit for summing an actuation period of the secondary air supplying device and storing a sum. The supply controller stops the secondary air supply by the secondary air supplying device when the sum stored by the summing unit reaches a predetermined upper limit. The summing unit resets the stored sum, if a difference between the coolant temperature and the intake air temperature at a point before the actuation of the secondary air supplying device is not more than a predetermined value. This configuration enables the apparatus to suppress oversupply of secondary air and overheating of a catalyst so as to implement appropriate activation of the catalyst.

摘要： A failure diagnosis apparatus for secondary air supplier according to the present invention determines a failure of a secondary air supplier based on pressure and pressure pulsation in a secondary air supply path. A failure diagnosis is made by determining the presence or absence of pressure pulsation in the secondary air supply path based on a determination threshold, and in the present invention the determination threshold is varied according to a pressure value in the secondary air supply path (a smoothed value or an average value of measured pressure). This permits the apparatus to make an accurate failure diagnosis, while eliminating pressure pulsations except for that due to exhaust pulsation (e.g., that due to noise of the pressure sensor and that caused by surging of an air pump).

摘要： An anomaly judgment apparatus for a secondary air supply system which includes a secondary air supply path for introducing secondary air from an intake path of an engine into an exhaust path at a location upstream of a catalytic converter disposed in the exhaust path. The apparatus includes a pressure detector for detecting pressure in the secondary air supply path, and an anomaly judgment section for calculating pulsation level indicative of the degree of pulsation of pressure detected by the pressure detector and for judging, on the basis of at least the pulsation level, whether or not the secondary air supply system is anomalous. The apparatus further includes an anomaly judgment prohibiting section for prohibiting judgment by the anomaly judgment section when the degree of propagation of intake air pulsation arising in the intake path into the secondary air supply path is equal to or higher than a predetermined level.
