摘要： PROBLEM TO BE SOLVED: To reduce the vibration of an internal combustion engine on startup, and to secure combustion stability on initial explosion. SOLUTION: In response to a request to start an engine, torque commands Tm1* and Tm2* are transmitted to motors MG1 and MG2 in such a state that intake air quantity is reduced until a surge tank internal pressure STP is turned to be a threshold STPref or less to carry out the motoring of the engine. Then, a compression force in a compression process is reduced, and vibration on startup is reduced, and inhalation air quantity is reduced, so that the torque on initial explosion is reduced, and that the vibration on initial explosion is reduced (S100 to S170). On the other hand, air is circulated in the engine in such a state that fuel is cut during motoring, and when the motoring time is prolonged, a section which should be originally gotten wet due to fuel is dried. Then, an increase value originated from motoring is set based on the motoring time so that fuel which should be supplied to combustion can be prevented from running out due to the attachment of fuel to the dried section, and combustion can be stably carried out on initial explosion as a result (S200 to S240).

摘要： PROBLEM TO BE SOLVED: To make effective use of the regenerative power of a motor and enhance the energy efficiency of an entire vehicle in an automobile provided with the motor capable of generating power by power from an axle. SOLUTION: The automobile is provided with the motor MG2 connected with driving wheels 39a and 39b. When the regenerative power of the motor MG2 exceeds a limit value on the power with which a battery 50 can be charged, the excess power is consumed at an electric heater 66 and is stored as heat in a heat accumulation tank 65. When a request is made to start an engine 22, the setting of a three-way valve 68 is changed so that the heat exchange medium in the heat accumulation tank 65 is supplied to the engine 22 until the engine water temperature becomes equal to or higher than a predetermined temperature. Thus, the regenerative power of the motor MG2 can be utilized without wastage as required, and the energy efficiency of the vehicle can be further enhanced. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To extend a fuel cut area or reduce fuel injection quantity while suppressing an engine stall even in the change in a load torque acting on an internal combustion engine.
SOLUTION: When a rotating speed NE is a fuel cut rotating speed NT or more in the deceleration of a vehicle, a fuel cut flag Ffc is set to 1 in step S305, and a fuel cut is executed. During this fuel cut, a torque deviation ΔT is calculated from a standard torque Tt and an output torque TE in steps S306 and S307. A fuel cut returning rotating speed NR is calculated based on the torque deviation ΔT in step S308, and when the rotating speed Ne is lower than the fuel cut returning rotating speed NR, the fuel cut is stopped (steps S310 and S311).

摘要： PROBLEM TO BE SOLVED: To properly control a valve phase during idle operation of an internal combustion engine, in a variable valve timing mechanism having a structure in which the change ratio (deceleration ratio) of the valve phase with respect to operation quantity of an actuator is changed in response to the valve phase. SOLUTION: An idle time target phase setting part 130 variably sets a target phase CAr in response to an idle target engine speed NIr set by an idle target engine speed setting part 110. In particular, when it is determined by an engine temperature determination part 135 that the engine 1000 is in a cold state, the idle time target phase setting part 130 sets the target phase CAr so that a change range of the valve phase is restricted within a phase area where the deceleration ratio is large and operation noise is relatively suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve timing device capable of preventing an unintended change of valve timing from occurring when an engine is stopped. SOLUTION: The variable valve timing device changes a valve phase by reducing the operating amount of an actuator with a reduction ratio different depending on a phase area. When a valve phase is out of the range of a large reduction ratio 2500 in which the ratio of the changed amount of phase to the operating amount of the actuator is small when the engine is stopped, the actuator is operated by the reaction force of a camshaft, and an unintended phase change may occur. When an engine stop instruction may be given while the engine is operating during the starting of the engine and the stoppage of a vehicle, a target phase position is limited to the area on the retard angle side of the phase limit value IVlmt set in consideration of the valve timing amount changeable between the occurrence of the engine stop instruction and the engine stop.

摘要： 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

摘要： 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
