    Abstract: PROBLEM TO BE SOLVED: To improve judging accuracy when the existence of failure of a switching mechanism for switching an exhaust passage is judged, in relation to an exhaust passage switching device for an internal combustion engine. SOLUTION: A switching mechanism 70 is disposed to switch the exhaust passage with a main passage 30 and a bypass passage 32 by leading negative pressure of an intake manifold 14. The switching mechanism 70 is provided with a switching valve 34, a diaphragm mechanism 40, a negative pressure supplying piping 50, and a VSV 52. When the VSV 52 is turned on, negative pressure is supplied to a transformation chamber 44 of a diaphragm mechanism 40, a diaphragm 42 is deflected, and then, the switching valve 34 is closed interlockingly therewith. The existence of the failure of the switching mechanism 70 is judged on the basis of pressure of the negative pressure supplying piping 50 when the VSV 52 is turned on. Before the VSV 52 is turned on, namely, in a condition in which the VSV 52 is turned off, in the case where pressure in the negative pressure supplying piping 50 is not held to the atmospheric pressure, failure judgment of the switching mechanism 70 is inhibited on the basis of pressure of the negative pressure supplying piping 50.

    Abstract: PROBLEM TO BE SOLVED: To protect a cylinder fuel injection valve when fuel injection from the cylinder fuel injection valve is limited, and to cope with required power for a driving shaft as much as possible, in a power output device provided with an internal combustion engine having the cylinder fuel injection valve and a fuel injection valve for a port and an electric motor. SOLUTION: A hybrid automobile 20 is provided with the engine 22 having the cylinder fuel injection valve 125 and the fuel injection valve 126 for the port. In the automobile, opening and closing timing of an intake valve of the engine 22 is angle-delayed when an engine start-up condition is satisfied, and fuel is injected from the fuel injection valve 126 for the port to start the engine 22 when a temperature of an emission control device for exhaust from the engine is less than a threshold value. The fuel injection from the fuel injection valve 126 for the port is continued to warm up the emission control device by idling-operating the engine 22. A torque necessary for travel is output therein from the motor MG2 within a range of input and output limitation of a battery 50. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To continuously suppress catalyst degradation in catalyst degradation suppressing control, even though the number of revolutions of an internal combustion engine is forcibly reduced. SOLUTION: When a fuel cut condition is met and catalyst degradation suppressing control is requested in a power output device (YES at S150), a second upper limit quantity of air is computed; if the absolute value of a torque command Tm1* for a motor MG1 exceeds the absolute value of a threshold value Tref, and the number Ne of engine revolutions is being reduced (YES at both S190 and S192). The second upper limit quantity of air is larger than a first upper limit quantity of air obtained by adding a predetermined amount of padding to a target intake air quantity for autonomous operation at the engine revolutions Ne of this time. Then, a control signal is transmitted to an engine ECU so that explosive combustion is executed within the range that the actual intake air quantity does not exceed the second upper limit quantity of air (S196). Thus, when the engine revolutions Ne is forcibly reduced by the motor MG1, the possibility is increased that explosive combustion is continuously executed. As a result, a catalyst constituting a purifying device is hardly degraded. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To prevent a catalyst of a hybrid vehicle from being exposed to a high-temperature lean atmosphere and to match power output from an engine with required power for an engine. SOLUTION: When the required power for the engine is not zero (NO in S320), since an air amount is not increased (S330), the required power for the engine matches with the power output from the engine. On the other hand, when the required power for the engine is zero (YES in the S320), the air amount is increased (S340) and no-load operation of the engine is performed. Therefore, even if the air amount is increased, the output power does not fluctuate, and a fuel injection amount appropriate for the increased air amount is calculated based on a target air-fuel ratio to increase the fuel injection amount, and the exhaust is not in the lean atmosphere. Therefore, the exhaust catalyst is prevented from being exposed to the high-temperature lean atmosphere. COPYRIGHT: (C)2006,JPO&NCIPI

    解决方案：当发动机所需的功率不为零（S320中为“否”）时，由于空气量不增加（S330），发动机所需的功率与发动机输出的功率匹配。 另一方面，当发动机的所需功率为零（S320中为“是”）时，空气量增加（S340），并且执行发动机的空载运转。 因此，即使空气量增加，输出功率也不会波动，并且基于目标空燃比计算适合于增加空气量的燃料喷射量，以增加燃料喷射量，并且排气不是 在精益气氛中。 因此，可以防止排气催化剂暴露于高温稀薄气氛。 版权所有（C）2006，JPO＆NCIPI
