    Abstract: PROBLEM TO BE SOLVED: To provide a control device for a vehicular internal combustion engine optimizing overlap quantity control in an internal combustion engine equipped with a variable valve timing mechanism. SOLUTION: When the engine is gets in idling operation state, this device waits for stop of a vehicle. When the vehicle stops, the device sets overlap quantity of an intake valve and an exhaust valve small. Consequently, vibration of the engine in the vehicle stop state is reduced. Even if the engine is in idling operation, the overlap quantity is set greater than that in normal control if the vehicle is travelling. Consequently, engine load is increased by accelerator step-in action of a driver during vehicle travel or the like, and the overlap quantity is appropriately provided in a state where engine speed rises.

    解决方案：当发动机处于空转运行状态时，该装置等待停车。 当车辆停止时，设备将进气门和排气门的重叠量设置得较小。 因此，发动机在车辆停止状态下的振动减小。 即使发动机处于怠速运转状态，如果车辆正在行驶，则重叠量设定为大于正常控制。 因此，通过驾驶员在车辆行驶等期间的加速器踏入动作来增加发动机负荷，并且在发动机转速上升的状态下适当地设置重叠量。 版权所有（C）2011，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To suppress a temperature rise of a catalyst for purifying engine exhaust gas. SOLUTION: A throttle opening degree TH is set to an opening degree Th2 larger than an opening degree Th1 at which fuel cut and start of fuel injection are not repeated frequently (step S260), when the fuel cut and the start of the fuel injection are repeated frequently (step S120). The fuel injection to an engine 22 is started (step S300), when the throttle opening degree TH becomes to the opening degree Th2 and when the catalyst temperature Tc is lower than a temperature Tc1 (steps S280, S290), and the engine 22 and motors MG1, MG2 are controlled to output a driving force based on a required torque Tr* to a ring gear shaft 32a as a driving shaft (steps S190-S230) in traveling. The catalyst temperature is thereby suppressed from rising. COPYRIGHT: (C)2010,JPO&INPIT

    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
