Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of exhaust properties in starting an internal combustion engine in a vehicle having the intermittently operated internal combustion engine. SOLUTION: An engine ECU 1000 carries out intermittent operation control on an engine 120 mounted to a hybrid vehicle. The engine 120 is provided with an EGR device, and its flow rate is controlled by an EGR valve 502 via an EGR pipe 500 from the downstream side of a three-way catalyst converter 900. When an engine stop request is made, the engine ECU 1000 makes the engine 120 perform idle operation and outputs a control signal (a valve closing signal) to the EGR valve 502 to stop operation of an EGR. Then, the engine ECU 1000 estimates a residual amount of EGR gas inside an intake pipe based on an intake air amount detected by an air flow meter and the like, and if the estimated EGR gas residual amount is not above a predetermined value, the engine ECU 1000 carries out engine stopping process.

Abstract: PROBLEM TO BE SOLVED: To provide a power output device, a vehicle mounted with the device and a control method of the power output device, capable of further protecting a purification means for purifying exhaust gas of an internal combustion engine of starting by delaying the ignition timing. SOLUTION: A hybrid automobile 20 starts an engine 22 by igniting in the ignition timing set on the more ignition timing delay side than the ignition timing set in operation after starting the engine 22 when a starting condition is realized when stopping the engine 22. The engine 22 is stopped when the temperature of a purification device 134 is a threshold value or less after a stopping condition is realized, and operation of the engine 22 is continued by igniting in the ignition timing after starting when the temperature of the purification device 134 is higher than the threshold value after the stopping condition is realized. Thus, restarting of the engine 22 is prevented by continuing the operation of the engine 22 when the temperature of the purification device 134 exceeds the threshold value, to prevent high temperature exhaust gas generated when starting in the ignition timing on the ignition timing delay side from flowing in the purification device 134.

Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of vibration during the idling operation of an internal combustion engine in which the opening and closing timing of an intake valve is variable. SOLUTION: A hybrid automobile 20 comprises a variable valve timing mechanism 150 and a lock pin 154 for fixing the variable valve timing mechanism 150 at the most retard angle position. When the requirements for idling are fulfilled and the fixing of the lock pin 154 at the most retard angle position at which a compression pressure in a cylinder is low is released, the engine 22 is idle-controlled at a position advanced from the most retard angle position. When the requirements for idling are fulfilled and the locking of the lock pin 154 at the most retard angle is not released, a control different from idling control is performed. Specifically, the controllable charging of a battery 50 or the stoppage of the engine 22 is selectively performed based on the remaining capacity SOC of the battery 50. Consequently, the idle control of the engine 22 when the compression pressure in the cylinder is low can be avoided. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress air bubbles in fuel caused by the atmospheric pressure, in a fuel supply device capable of reducing the pressure of fuel inside a fuel supply pipe for supplying fuel to a cylinder fuel injection valve by using the atmospheric pressure.
SOLUTION: An automobile 20 is equipped with a high pressure pump 64 for further pressurizing fuel inside a fuel pipe 63 and supplying the fuel to a delivery pipe 66 to which the cylinder fuel injection valve 25 is connected, and with an electromagnetic-type relief valve 67 capable of reducing the pressure of pressurized fuel inside the delivery pipe 66 by using the atmospheric pressure. During stop of an engine 22, when the atmospheric pressure detected by an atmospheric pressure sensor 89 exceeds a threshold value, the relief valve 67 is opened only for opening time corresponding to the atmospheric pressure and fuel pressure, so as to reduce the fuel pressure. When the atmospheric pressure is below the threshold value, opening of the relief valve 67 is not performed. In this case, by using the atmospheric pressure correlated with presence/absence of air bubbles inside the delivery pipe 66, reduction of the fuel pressure inside the delivery pipe 66 is restricted.

Abstract: 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).
