    摘要: A fuel vapor treatment apparatus includes a first canister, a purge passage, an atmosphere passage, a first detection passage provided with a restrictor, and a passage-changing valve for changing the connection passage of the first detection passage between the purge passage and the atmosphere passage. The apparatus further includes a second canister connecting with the first detection passage on the opposite side of the passage-changing valve across the restrictor. A differential pressure sensor detects a pressure difference between both ends of the restrictor. An ECU computes the concentration of fuel vapor on the basis of the detection result of the differential pressure sensor.

    摘要: An image forming apparatus includes a power supply control unit that performs control of switching a power supply source to an auxiliary power supply that stores therein power from a main power supply when the main power supply is off, and control of switching the power supply source to the main power supply when the main power supply is on; a detection unit that detects whether the power supply source is the main power supply or the auxiliary power supply; and a mode control unit that performs control of switching between a normal mode and a power-saving mode in which power consumption is smaller than in the normal mode. The mode control unit performs control of setting a switching time to switch from the normal mode to the power-saving mode to a shorter time when the power supply source is the auxiliary power supply.

    摘要: An exhaust gas purifying apparatus for an internal combustion engine includes a lean control unit and a rich control unit. The lean control unit executes lean spike operation, in which an air-fuel ratio is temporarily changed in a lean direction by a lean change width relative to a reference air-fuel ratio. The rich control unit changes the air-fuel ratio in a rich direction by a rich change width relative to the reference air-fuel ratio after the lean control unit executes the lean spike operation such that the air-fuel ratio stays in a predetermined slightly rich region. The rich change width is smaller than the lean change width.

    摘要: In a non-critical pressure region where a pressure ratio [Pm/Pthrup(i−1)] of an intake air pressure Pm (throttle downstream pressure) detected by an intake air pressure sensor to a previous throttle upstream pressure Pthrup(i−1) is greater than a predetermined value B, the previous throttle upstream pressure Pthrup(i−1) is substituted for one of two terms of the throttle upstream pressures Pthrup(i) included in an intake system model so that present throttle upstream pressure Pthrup(i) is calculated. In a critical pressure region where the pressure ratio is less than or equal to the predetermined value B, a physical value f(Pm/Pthrup(i)) using a pressure ratio [Pm/Pthrup(i)] of the intake air pressure Pm to a present throttle upstream pressure Pthrup(i) as a parameter is regarded as a steady value fc so that the present throttle upstream pressure Pthrup(i) is calculated.

    摘要: A secondary air pipe is connected on the upstream side from catalyst in an exhaust pipe, and a secondary air pump is provided at an upstream portion of the secondary air pipe. An opening/closing valve for opening/closing the secondary air pipe is provided on the downstream side from the secondary air pump. A pressure sensor for detecting pressure within pipe is provided between the secondary air pump and the opening/closing valve. An ECU calculates a secondary airflow rate based upon difference pressure between both secondary air supply pressure which is detected by the pressure sensor when the opening/closing valve is opened under such a condition that the secondary air pump is operated, and also, shutoff pressure which is detected by the pressure sensor when the opening/closing valve is closed.

    摘要: A secondary air pipe is connected to an exhaust pipe upstream of a catalyst, and a secondary air pump is connected to an upstream portion of the secondary air pipe. An ECU determines an operating period of the secondary air pump before the secondary air pump is operated in order to drive the secondary air pump within the operating period. Especially, the ECU detects a pump driving load during a secondary air supply to correct the operating period of the secondary air pump based on the detected pump driving load.
