摘要： A control apparatus for an internal combustion engine, where a calculated fuel injection quantity is corrected with a purge-air-concentration learnt value calculated by subjecting a purge air concentration to purge-air-concentration filtering. A filtering effect in the purge-air-concentration filtering is changed in the direction of enhancing exhaust gas purification, when the purge air concentration is thick and when the purge air concentration is thin, whereby an air/fuel ratio introduced into the internal combustion engine is precisely controlled to a target air/fuel ratio so as to enhance the exhaust gas purification.

摘要： Provided is a power-generation control device capable of appropriately using a drive belt looped around a power generator and an internal-combustion engine mounted on a vehicle. The device monitors a difference between an actual generated current of a rotating electrical machine and an estimated generated current estimated from estimated power-generation torque for controlling power generation of the rotating electrical machine, which corresponds to a power-generation torque command, or the like. When a difference equal to or more than a predetermined value occurs between the actual and the estimated generated currents, the power-generation control device limits the estimated power-generation torque so as to be reduced, and further limits the estimated power-generation torque with use of learning limiting power-generation torque calculated based on the estimated power-generation torque at a time when the difference has occurred between the actual generated current and the estimated generated current.

摘要： An automatic starting device for the engine, which quietly and quickly restarts the engine when a re-acceleration request is made by a driver, is provided. In a case where it is judged that a vehicle is decelerating and fuel injection is currently stopped, when it is then judged that a brake pedal is released and an engine rpm is smaller than an engine rpm which allows recovery from a fuel-supply stop state, the controller disengages a lock-up clutch. Upon detection of reverse rotation of the engine based on a detection signal of the crank-angle sensor, the controller controls a pinion gear to be pushed out by a lever of a starter to be meshed with a ring gear. After the ring gear is rotated by a predetermined angle, the controller rotary-drives a motor of the starter to restart the engine.
