Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of suppressing the deterioration of exhaust emission resulting from the response delay of an exhaust sensor when automatic start or the return of fuel cut is performed in the fuel injection control device for setting a fuel injection amount so that an actual air-fuel ratio in starting an engine or returning the fuel cut becomes richer than a theoretical air-fuel ratio in the internal combustion engine in which the automatic stop and automatic start of the engine are performed and in the internal combustion engine in which the fuel cut and the return of the fuel cut are performed. SOLUTION: This fuel injection control device is formed to perform air-fuel ratio feedback control when the detection signal of the exhaust sensor after automatic stop is determined to be rich. Also, the detection signal of the exhaust sensor after automatic start is determined not to be rich in the device, it is determined whether a specified time TA is passed from the automatic start or not. When the specified time TA is not passed, the start of the air-fuel ratio feedback control is prohibited and when the specified time TA is passed, the air-fuel ratio feedback control is performed.

Abstract: PROBLEM TO BE SOLVED: To provide a warming-up apparatus of an internal combustion engine for appropriately avoiding a decrease in the recovery efficiency of a heating medium. SOLUTION: The warming-up apparatus of the internal combustion engine is applied to a hybrid vehicle for mounting a navigation system NS, thus supplying cooling water stored in a heat-storing tank 21 to the internal combustion engine 11 via an electric water pump 22, and hence promoting the warming-up of the internal combustion engine 11. When the current location of the hybrid vehicle in the navigation system NS arrives around a destination set to the navigation system NS, the cooling water that absorbs heat in the internal combustion engine 11 and becomes a high temperature is recovered into a heat-storing tank 21 through the electric water pump 22.

Abstract: PROBLEM TO BE SOLVED: To provide an engine accessory driving device of an internal combustion engine for enhancing the responsiveness of the internal combustion engine to the load request while driving an engine accessory. SOLUTION: One end of a drive shaft 25 of a compressor 24 is connected to one end of a connection shaft 27 of a motor 26, and a compressor pulley 22 is attached to the other end of the connection shaft 27. A belt 21 is stretched between the compressor pulley 22 and a crank pulley 20 of an engine 11. A one-way clutch mechanism is provided on the compressor pulley 22. When acceleration is requested to the engine 11, the rotational speed of a retainer to be rotated by the motor 26 is set to be higher than the rotational speed of a rotary yoke to be rotated by the engine 11 in the one-way clutch mechanism. The rotary yoke is idled with reference to the retainer, and the load to be transmitted from the compressor 24 to the engine 11 is cut off thereby. COPYRIGHT: (C)2004,JPO

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.

Abstract: PROBLEM TO BE SOLVED: To inhibit defect caused by the condition of a catalyst during motoring primarily aiming at reducing shock in starting of an internal combustion engine. SOLUTION: In this hybrid automobile, when the exhaust gas purifying catalyst is judged to be in a proper state at step S112, the motoring is continued to reduce an intake air volume into cylinders until intake pipe pressure P reaches a predetermined negative pressure Pref and then combustion control is started. On the other hand, when the exhaust gas purifying catalyst is judged not to be in the proper state at step S112, the combustion control is started even if the intake pipe pressure P is not smaller than Pref. Namely, the combustion control is early performed when catalyst temperature is in a low temperature condition wherein exhaust emission control capacity is lowered or when the catalyst temperature is in a high temperature condition wherein deterioration is accelerated through exposure to air, and therefore the defect caused due to the condition of the catalyst during the motoring such as the degradation of emission and the acceleration of deterioration of the exhaust gas purifying catalyst can be inhibited while primarily aiming at reducing shock in starting of the engine.
