    摘要： An electric power generating apparatus is mounted on a vehicle which has a propulsive electric motor powered by a battery, and has an electric generator and an internal combustion engine for actuating the electric generator to charge the battery depending on a charged/discharged state of the battery. A first operation controller operates the internal combustion engine to enable the electric generator to charge the battery if the amount of electric energy stored in the battery is smaller than a predetermined value or the time-dependent rate of increase of an amount of electric energy discharged from the battery is greater than a predetermined level. A second operation controller operates the internal combustion engine to purge a canister if the charged/discharged state of the battery fails to satisfy a condition for the first operation controller to operate the internal combustion engine and if the amount of a purged gas adsorbed in the canister is greater than a predetermined amount. The first and second operation controllers operate the internal combustion engine in modes established respectively for the first and second operation controllers such that a load imposed on the internal combustion engine when the internal combustion engine is operated by at least the second operation controller is smaller than a load imposed on the internal combustion engine when the internal combustion engine is operated by the first operation controller.

    摘要： A hybrid vehicle is equipped with an internal combustion engine, a motor/generator, and a Rankine cycle system for recovering thermal energy of exhaust gas. The output of the Rankine cycle system is input into a transmission or, alternatively, converted into electric power and used for charging a battery. The Rankine cycle system has temperature setter that sets the temperature of steam at the outlet of an evaporator. A pressure setter is provided for setting steam pressure at the inlet of an expander. A pressure controller is provided for controlling the steam pressure at the inlet of the expander. The evaporator generates steam to be supplied at a pressure that is optimum for the expansion ratio of the expander. The Rankine cycle system is operated when the vehicle is accelerating or cruising and efficiently recovers thermal energy of the exhaust gas and reduces the fuel consumption of the internal combustion engine.

    摘要： A method and apparatus are provided for controlling the solenoid current of a solenoid valve which controls the amount of suction air in an internal combustion engine. An actual current flowing through the solenoid is detected and a solenoid current control value is calculated as a function of engine operating conditions. A corrected solenoid current control value is determined as a function of the solenoid current control value and a feedback control term is calculated as a function of the difference between the corrected solenoid current control value and the actual solenoid current. An initial value for the feedback control term is determined as a function of an integration term which forms part of the feedback control term. A pulse duration signal is determined as a function of the corrected solenoid current value and an output pulse duration signal is calculated as a function of the pulse duration signal and the feedback control term. In another aspect, a predetermined current control value is used as the corrected solenoid current control value when the engine speed is above a predetermined value. In still a further aspect, the output pulse duration is corrected as a function of battery voltage.

    摘要： When the engine RPM falls below a lower limit of a target RPM of idling while an engine is in an idle operation, a control valve is shifted to the open-loop control mode instead of the conventional feedback control mode so as to enable the engine RPM range to be quickly increased up to within the target RPM of idling rotations. Said control valve is disposed in a bypass which communicates with the upstream side and the downstream side of the throttle valve in intake passage to adjust the volume of an inspired air. The solenoid current command (amount of control) for adjusting the opening degree of the control valve during the period of the open-loop control mode is set at a level higher than that immediately before the feedback control mode shifts to the open-loop control mode.
