PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of separating a diluted fuel from an oil while ensuring the excellent emission characteristic when oil dilution occurs. SOLUTION: When it is determined that oil dilution occurs, the rise of oil is generated by the in-cylinder negative pressure generated by delaying and/or advancing an intake valve, and a fuel is evaporated from the oil diluted with the fuel (Step 106). In this step 106, discharge of the evaporated fuel to an exhaust passage is prevented by stopping an exhaust valve in a closed state. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an electric vehicle where starting frequency of battery ECU is suppressed to the necessary minimum while a state of a capacitor device is appropriately monitored when the capacitor device is charged in a stop mode of the vehicle. SOLUTION: While a main capacitor device B1 using a solar battery 24 is being charged in the stop mode of the vehicle, charging control ECU 28 activates command EN1 at prescribed frequency and starts battery ECU 30. To put it concretely, charging control ECU 28 stops battery ECU 30 when it acquires a temperature TB of the main capacitor device B1 from started battery ECU 30. Charging control ECU 28 decides a time until battery ECU 30 is started next, based on the temperature TB of the main capacitor device B1, which is acquired at this time and the battery ECU 30 starting time until then.

PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of inhibiting deterioration of drivability at a time of recovery from fuel cut by appropriately securing negative pressure in an intake system while preventing introduction of fresh air to a catalyst at a time of fuel cut. SOLUTION: The control device for the internal combustion engine controls the internal combustion engine executing fuel cut during deceleration of a vehicle. An intake valve control means closes an intake valve provided at a combustion chamber during fuel cut. An intake system sealing valve control means controls an intake system sealing valve provided in the intake air passage to close at a time of start of fuel cut. Consequently, flow-in of intake air to the intake air passage between the intake valve and the intake system sealing valve is shut off and a negative pressure condition is maintained during fuel cut. Sudden torque rise at a time of recovery from fuel cut can be inhibited while performing quick introduction of fresh air to a catalyst by the control device for the internal combustion engine.

PROBLEM TO BE SOLVED: To rightly and stably regenerate an NOx adsorbing catalyst, by effectively using engine output reduction or stopping control performed by a determination of an electric control device, in a hybrid car. SOLUTION: This hybrid car regenerates the NOx adsorbing catalyst by a rich spike when an NOx adsorbing quantity of the NOx adsorbing catalyst reaches a predetermined upper limit value. When an engine stopping request or an engine idling request is outputted, when the NOx adsorbing quantity is a predetermined limit value or more lower than the upper limit value, an engine is temporarily put in an idle state, and the NOx adsorbing catalyst is regenerated by the rich spike. The limit value may be enhanced in response to an increase in a frequency of the engine stopping or idling request. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To prevent worsening of exhaust property when restarting an engine and reduce and eliminate NOx stored by NOx storage reduction catalyst efficiently. SOLUTION: NOx storage reduction catalyst 17 is arranged in an exhaust pipe 15 of the engine 1 of a hybrid vehicle 100 to store NOx in exhaust gas when operating the engine 1 by lean air-fuel ratio. An electronic control unit (ECU) 30 of the engine 1 performs automatic start and stop operation for stopping the engine 1 when the vehicle stops and charging amount of a battery 9 is large and restarting the engine when starting running of the vehicle and reducing charging amount and increases a fuel injection amount increase value for the engine when restarting when NOx storage amount of NOx storage reduction catalyst is large. Consequently, total amount of NOx stored by NOx storage reduction catalyst can be properly reduced when restarting the engine. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine for preventing deterioration of drivability caused by decrease in the amount of electric storage of an electric storage device and decrease in the supercharging amount of a turbo charger. SOLUTION: An electric turbo 3 drives a motor by electricity supplied from a battery 5 to supply compressed air to an engine 2. A controller 4 controls supercharging amount of the electric turbo 3 and a shift ratio of a transmission 6 based on charging amount of the battery 5. In the case of little charging amount of the battery 5, the shift ratio of the transmission 6 is increased and the supercharging amount of the electric turbo 3 is lowered. Conversely, the shift ratio of the transmission 6 is reduced and the supercharging amount of the electric turbo 3 is increased in the case of much charging amount of the battery 5.

Abstract:
PROBLEM TO BE SOLVED: To provide a regenerative control device for a vehicle, which exercises control for recovering regenerative energy from a plurality of recovery sources and can recover the regenerative energy without waste even in switching between the recovery sources to be operated. SOLUTION: Control for the switching between the recovery sources to be operated is exercised in consideration of responsiveness until each of the recovery sources is brought into a prescribed recovery state. Specifically, in the switching from the first recovery source to be operated, which is quick in response, to the second recovery source to be operated, which is slow in the response, the regenerative energy is continuously recovered from the first recovery source until brought into a state of being sufficiently recovered from the second recovery source. Additionally, the continuous recovery of the regenerative energy from the first recovery source in the switching is gradually reduced up to a halt. COPYRIGHT: (C)2003,JPO
