摘要： An anomaly judgment apparatus for a secondary air supply system which includes a secondary air supply path for introducing secondary air into an exhaust path of an internal combustion engine and an open-close valve disposed in the secondary air supply path. The valve is opened and/or closed by drive force of negative pressure introduced from a portion of an intake path of the engine downstream of a throttle valve. The anomaly judgment apparatus includes an anomaly judgment section for judging whether or not the secondary air supply system is anomalous; a negative pressure judgment section for judging whether or not the negative pressure is secured to a degree required for the drive force to reliably open and/or close the open-close valve; and an anomaly judgment prohibition section for prohibiting judgment by the anomaly judgment section when the negative pressure is not secured to the required degree.

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 NOX occlusion and reduction catalyst 7 is arranged in an exhaust path 2 of an engine 1 to purify NOX in the exhaust gas. An electronic control unit (ECU) 30 of the engine operates the engine in an operating mode in which the exhaust gas increases in temperature with the air-fuel ratio thereof kept rich each time a predetermined amount of SOX is occluded in the catalyst 7, and executes the SOX poisoning restoration process for releasing SOX from the catalyst 7. The ECU controls the engine air-fuel ratio in such a manner that the H2 concentration in the exhaust gas detected by the H2 sensor arranged in the exhaust path upstream of the catalyst 7 is in a predetermined range. As a result, an appropriate amount of hydrogen is supplied to the catalyst 7 during the SOX poisoning restoration process. Thus, an appropriate amount of hydrogen is supplied to the catalyst 7 during the SOX poisoning restoration process, so that the H2S generation is suppressed while at the same time executing the SOX poisoning restoration process efficiently.

摘要： When a catalyst warm-up request for promoting warm-up of a catalyst is issued and no negative-pressure increase request for increasing a negative pressure downstream of a throttle valve is issued, a control system of an internal combustion engine controls the ignition timing to the timing (ϑ0+Δ ϑ1) obtained by correcting the normal ignition timing (ϑ0) to be retarded by a correction amount &Delta,−ϑ1, and controls the degree of opening of the throttle valve to a throttle opening (TAO+ΔTA1) that is larger than the normal throttle opening TAO by a correction amount ΔTA1. When the negative intake pressure must be increased for brake boosting when ignition is on the retard side, the throttle spending is reduced and the ignition is advanced gradually after some delay to avoid torque shock.
