摘要： An internal combustion engine control device includes a NOx adsorber catalyst disposed in an exhaust passage, an EGR passage, a reducing agent adding device, a torque fluctuation reducing device, and a fuel injection device. The EGR passage draws a portion of exhaust gas from the exhaust passage downstream of the NOx adsorber catalyst and recirculates the exhaust gas into the intake passage. The reducing agent adding device adds a reducing agent to exhaust gas upstream of the NOx adsorber catalyst to reduce substances adsorbed by the NOx adsorber catalyst. When or after the reducing agent adding device adds the reducing agent, the torque fluctuation reducing device advances the timing of the fuel injection device or carries out a pilot injection to reduce a fluctuation in engine torque. The reducing agent adding device adds less reducing agent while the torque fluctuation reducing device is operating.

摘要： In a control method of an internal combustion engine exhaust gas control system which is applied to a hybrid vehicle that is powered by an internal combustion engine and an electric motor, an exhaust throttle valve, provided downstream of an exhaust gas control catalyst, is controlled to reduce its opening amount to a target opening amount when it is determined that warm-up control of the internal combustion engine needs to be executed. Next, a target injection quantity of fuel necessary to increase the temperature of exhaust gas flowing into the internal combustion engine to a target exhaust gas temperature is calculated. Then, assist torque from the electric motor is adjusted so that the sum of torque from the internal combustion engine when the fuel injection quantity has been set to the target injection quantity and the assist torque substantially equals a required torque.

摘要： A control apparatus for an internal combustion engine includes an exhaust gas recirculation unit; an intercooler that is provided in the intake passage, at a position downstream of a position to which the exhaust gas is recirculated back; a bypass passage through which an intake air flow bypasses the intercooler. When it is determined that the pH of the condensed water obtained from the exhaust gas is at the level at which the intercooler corrodes in the state where the exhaust gas is recirculated back by the exhaust gas recirculation unit, the control apparatus executes a control for cutting off an intake air flow toward the intercooler to direct the intake air flow only to the bypass passage. Thus, it is possible to ensure reliability of the intercooler.

摘要： In a hybrid vehicle in which a fixed speed change mode can be realized by the locking of a rotational element, the mislocking of the rotational element is prevented. A hybrid drive apparatus which has an engine, a MG1 and a MG2 and which functions as a power unit of a hybrid vehicle is provided with a brake mechanism of a cam-lock type which can control the MG1 in a lock state and a non-lock state by changing the state of a sun gear between the lock state and the non-lock state. In mislocking prevention control, an ECU calculates MG1 angular acceleration Dωg, which is the absolute value of angular acceleration of the motor generator MG1, on the basis of a MG1 rotational speed Ngm1 and judges that the sun gear S1 is in a mislocking state if the MG1 angular acceleration Dωg is greater than a criterion value Dωgth.

摘要： A detection device for an internal combustion engine is preferably applied to the internal combustion engine which includes a temperature varying member, which is provided in an exhaust system, and whose temperature varies due to gas flow in the exhaust system. A temperature correlation value detection unit detects a correlation value which correlates with the temperature of the temperature varying member. The term correlation value herein includes impedance of the temperature varying member, a signal output value such as current and voltage output sent from the temperature varying member, and/or the temperature varying member's own temperature. A variation calculating unit calculates a variation of the correlation value, in a time period when the gas flow arises, detected by the temperature correlation value detection unit.
