Abstract: PROBLEM TO BE SOLVED: To inhibit deterioration of a part on an exhaust side of an internal combustion engine due to high temperature, and to inhibit emission of nitrogen oxide further and improve fuel economy while continuing appropriate combustion. SOLUTION: When an intake air quantity GA is not greater than a flow rate GAref, an EGR quantity Vb re-circulated into an intake pipe 125 is controlled by a small EGR valve 153. When an intake air quantity GA exceeds the predetermined flow rate GAref and the catalyst bed temperature Tcat exceeds a first temperature Tref1, the flow rate of an EGR gas recirculated by at least a large EGR valve 154 is controlled. Finer flow rate adjustment is performed when the intake air quantity GA is not greater than the flow rate GAref in this manner. When the intake air quantity GA exceeds the flow rate GAref and the catalyst bed temperature Tcat exceeds the first temperature Tref1, since the EGR gas of the flow rate greater than that by the small EGR valve 153 is recirculated, for example, fuel increase for reducing the temperature of exhaust emission control catalyst of the cleaning device 134 can be inhibited.

Abstract: PROBLEM TO BE SOLVED: To smoothly change opening/closing timing of a valve after starting an internal combustion engine. SOLUTION: When a start request for an engine is made, if an oil temperature Toil is not high in S140, a power output device sets a spark start number of rotations Nstart of the engine to a first number of rotations N1 in S150. If the oil temperature Toil is high, since the viscosity of operation oil is low and the oil pressure is slow in increasing, the device sets the number Nstart of the engine to a second number of rotations N2 larger the first number of rotations N1 in S160. By setting torque commands Tm1* and Tm2* using the number Nstart set in such a manner to transmit them to motors MG1, MG2 and by motoring the engine, the device surely unlocks a lock pin of a variable valve timing mechanism from a locking hole even when the oil temperature Toil is high. Therefore, the device can smoothly change the valve timing of an air intake valve after starting the engine. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To smoothly start an engine, and to prevent the deterioration of exhaust air aspect in a vehicle which is loaded with an internal-combustion engine equipped with a direct injection injector and an intake path injection injector and which controls engine intermittent operation. SOLUTION: When the operation of a vehicle ends, the fuel pressure of a high pressure delivery pipe 130 and a low pressure delivery pipe 160 is decreased due to the operation (release) of an electromagnetic relief valve 210 and the operation stop of a low pressure fuel pump 180, so that it is possible to prevent the deterioration of exhaust air aspect when an engine starts the next time due to fuel leakage by the deterioration of oil density in each injector 110 and 120 during the operation stop period. On the other hand, when the engine temporarily stops due to engine intermittent operation control, a low pressure fuel pump 180 is stopped, and the operation (release) of the electromagnetic relief valve 210 is inhibited. When the engine restarts after its temporary stop, the engine is made to quickly start by fuel injection in a high pressure delivery pipe 130 whose fuel pressure is secured, considering the rise of the temperature of the engine.
