摘要： PURPOSE:To provide high charging efficiency by preventing gum-like impure substance from depositing on a valve body while preventing the mixture from leaking into a branch passage at a low-speed and low-load run of an engine to aid formation of an intense swirl inside a combustion chamber and by opening and the branch passage to feed an ample flow of mixture into a helical part at a high-speed and high-load run thereof. CONSTITUTION:At a low-speed and low-load run of an engine, a rotary valve 25 is kept closed. Some of mixture sent into an inlet passage flows forward along the upper wall face 19 and 20, and a part of the rest runs against the rotary valve 25 and turns to flow along the side wall face 17. Since a part of the mixture flows against a valve body 31, if clearances between an edge 31a of the valve body 31 and a side wall face 27 and between opposite edge 31b of the valve body 31 and the second side wall face 14b are completely closed, gum-like impurities within mixture are deposited between valve body edges 31a, 31b and between the wall faces 27, 14b. For those purposes of preventing deposition of impurities and leakage from the clearance l1 and l2, annular recess 36 and 37 are formed.

摘要： PROBLEM TO BE SOLVED: To prevent a storage means from being charged/discharged by unexpected power by performing regulation so as to output desired motive force from a motor. SOLUTION: Energy Pe to be outputted from an engine is set so as to cancel deviation ΔPb between charging/discharging power Pb of battery and its target value Pb* (S116-S120), and the operation of engine is controlled so as to output this energy Pe (S122 and S134). The energy Pe outputted from the engine is converted by a clutch motor and an assist motor and outputted as motive force requested for a driving shaft and since the battery is charged/discharged by finding out the excess/lack of energy corresponding to this requested motive force, the charging/discharging power of battery can be regulated by regulating the energy Pe. When the target value Pb* is especially turned into a value 0, the motive force can be outputted to the driving shaft without charging/ discharging caused by unexpected power.

摘要： PROBLEM TO BE SOLVED: To early and accurately detect anomaly in the motors of an energy adjusting means equipped in a power output device. SOLUTION: A power output device 20 is provided with an engine 50, a clutch motor 30 containing an outer rotor 32 coupled with the crank shaft 56 of an engine 50 and an inner rotor 34 couple with the driving shaft 22, an assist motor 40 installed on the driving shaft 22, and a controller 80. The controller 80 controls intake air quantity and injection quantity so that an energy, expressed as the product of a target number of revolutions and a target torque, will be output from the engine 50 and controls the clutch motor 30, so that the engine 50 will be operated with the target torque. If the engine 50 operates normally and yet the number of revolutions of the engine 50 does not settle into the target number of revolutions during controlling, it is judged that the clutch motor 30 is faulty.

摘要： PURPOSE:To decrease frequency of charging/discharging of a battery and prevent drop of efficiency due to charge and discharge by allowing a generator to generate a power equal to the power which the motor for running requires. CONSTITUTION:A requisite motor output calculating means 10 determines the power which a motor for running requires, and the power generation amount to suit the obtained power value is calculated by a calculating means 12. In case the requisite power of motor is low, the engine load remains low, and only part of the cylinders is operated for reducing the throttle loss. On the basis of the power generation amount obtained from calculation, the engine speed is calculated by a calculating means 16, and an operating range judging means 18 judges whether the engine speed lies within the operating range according to the current operation mode, and if outside the operating range, a mode altering means 20 makes alteration of the number of cylinders in operation.

摘要： PURPOSE:To enable a power generating amount and an engine speed to be controlled to their optimum values by increasing and correcting the target value of the engine speed in detecting of knocking when the field current of a power generator or the engine driving condition are controlled by taking the engine speed and the power generating amount of the generator as target values. CONSTITUTION:A knock sensor 50 is provided on an engine 26, and whether the engine is knocked or not is judged by an ECU44 for inputting output of the knock sensor 50. The specific value alpha is added to the correction amount DELTAN1 of the target engine speed NTO when knocking is not generated, while the specific value alpha is subtracted from the correction amount DELTAN1 of the target engine speed NTO, so as to add the obtained correction valve DELTAN1 to the target engine speed NT. The basic duty DO is found from the such obtained target engine speed NT, and a separately set duty correction valve DELTAD is added to it, and the field current of a generator 22 is controlled according to the found duty D.

摘要： PURPOSE:To prevent running feeling and emission level from degrading by making a decision whether the vehicle speed has been sustained within a predetermined range for a predetermined time or longer and sustaining a previous control target value of generating power if the answer is negative. CONSTITUTION:A vehicle speed decision means D decides whether the vehicle speed has been sustained within a predetermined range for a predetermined time or longer. If the answer is negative, a previous control target value is sustained. A generating power control means E controls power generated from an engine driven generator C based on such control target value. This constitution prevents the running feeling from degrading due to intermittent fluctuation of vibration/noise level of the engine driven generator C under a state where the vehicle speed varies frequently while furthermore preventing the emission level from lowering due to fluctuation of engine A load.

摘要： PURPOSE:To improve charge/discharge balance of a battery by controlling the power generated from an engine driven generator while correcting a target power based on the average value of input power to a motor from the engine driven generator and the battery. CONSTITUTION:Input power to a motor A from an engine driven generator E and a battery B is detected and averaged through an average value operating means G and the set value of target power is corrected based on the average value. Power generated from an engine driven generator E is then controlled based on the target power thus corrected. Since the target value of power generated from the engine driven generator E is corrected depending on the fluctuation between vehicles, drift of the motor A, operating manner of operator, etc., fluctuation in charge/discharge balance of the battery B is suppressed. This constitution prevent) deterioration of the battery B and enhances total efficiency of a vehicle.

摘要： PURPOSE:To enlarge the controllable region of generating power while sustaining and enhancing efficiency through the use of a generator equipped with a permanent magnet. CONSTITUTION:An engine driven generator 34 comprising an engine 36 and generators 38, 40 equipped with permanent magnets is employed. The engine 36 is coupled with the generators 38, 40 through clutches 42, 44. Magnetomotive force of permanent magnets in the generators 38, 40 is determined by proportionally dividing the maximum power demand of the engine driven generator 38. An ECU 46 operates the generator 38 or 40 selectively depending on the power demand of the engine driven generator 34.
