    摘要： An engine has a variable valve actuation mechanism that varies lift characteristics of an intake valve. An idle speed control apparatus has a control section for controlling an intake air amount of the engine in an idle state for adjusting an actual engine speed to a target engine speed. The control section sets a control amount related to control of the intake air amount in correspondence with the lift characteristics, which are varied by the variable valve actuation mechanism. Accordingly, the engine speed in the idle state is effectively controlled in correspondence with changes of the lift characteristics.

    摘要： An inter-bank variation detection device of an internal combustion engine provided with a valve opening characteristic setting means (57) for changing the valve opening characteristic of an intake valve (9) for each of the cylinders (#1 to #4) or each of the bank (BL, BR); an indicator detecting means for detecting indicators of the state of combustion for each bank at the time of a first valve opening characteristic set by the valve opening characteristic setting means and the time of a second valve opening characteristic smaller than the first valve opening characteristic; a fuel injection amount variation detecting means (27) for detecting variation of the fuel injection amount for each bank by using the indicator (Xfn) detected by the indicator detecting means at the time of the first valve opening characteristic; and a valve opening characteristic variation detecting means (27) for detecting variation of the valve opening characteristic for each bank by using the indicator (Xsn) detected by the indicator detecting means at the time of the second valve opening characteristic and the variation of the fuel injection amount detected by the fuel injection amount variation detecting means is provided. It is also possible to change the valve opening characteristic of the intake valve by the valve opening characteristic setting means so that the variation of valve opening characteristic for each cylinder or each bank is eliminated.

    摘要： A combustion condition for each of plural cylinders included in an internal combustion engine is set by the following control that is performed according to an intake air amount in each of the plural cylinders. A reference cylinder is set to a cylinder in which the intake air amount is smallest, and a fuel injection amount for the reference cylinder is set to a fuel injection amount for realizing a stoichiometric air-fuel ratio. The air-fuel ratio in each of the cylinders other than the reference cylinder is set according to the intake air amount in each of the cylinders such that the torque equal to reference torque generated in the reference cylinder is generated. When this setting is performed, air-fuel ratios that are out of a predetermined region in the vicinity of the stoichiometric air-fuel ratio (i.e., air-fuel ratios that are in an avoidance region) are excluded. With respect to a cylinder in which the torque equal to the reference torque cannot be generated only by setting the air-fuel ratio, correction of the ignition timing is further performed so as to suppress a difference between the torque generated in the cylinder and the reference torque.

    摘要： The power circuit device for vehicles is provided with a grounding portion for grounding portions closer to a power consumption device side than a relay of main conductive routes when the relays used for the main conductive routes extending from an accumulator of a vehicle to a fuel heating device, a catalyst heating device, an electric pump, or the like is turned OFF, so that a false power application is not executed even a short-circuit occurs in a part of a power circuit. Also, when two relays are arranged in series, the grounding portion is provided for the relay closer to the power consumption device in order to monitor a voltage level of the main conductive route and make it easy to detect a short-circuit or a disconnection occurrence.
