    摘要: The warming up control device according to the present invention determines precisely whether the temperature of the catalytic converter of the internal combustion engine has reached the activating temperature of the catalyst after the engine starts, The device estimates the heat amount transferred from the exhaust gas the catalytic converter based on the amount of the fuel supplied to the engine, and calculates the total heat amount transferred to the catalytic converter after the engine starts. The device determines that the temperature of the catalytic converter reaches the activating temperature of the catalyst when the calculated total heat amount reaches a predetermined value. Since the completion of the warming up of the catalytic converter is precisely determined, the warming up operation of the catalyst, such as the ignition timing retardation, can be terminated at a proper time, thus an unnecessary increase in fuel consumption and a deterioration in the engine performance can be avoided.

    摘要: A turbine, which is an essential portion of an air motor, is disposed midway along an air-intake passage communicating to combustion chambers of an engine. A generator is operably connected to an output shaft of the turbine. The generator has a function to control the rotational motion of the turbine in proportion to the magnitude of the generated electric energy, in addition to the original function of generating the electric energy. The generator is electrically connected to an air-intake control device. In other words, the air-intake control device includes a transistor, and potentiometer which includes a resistor and a sliding element. A positive electrode of generator is connected to an emitter of the transistor. Further, a base of the transistor is connected to an output terminal of the potentiometer, and a collector thereof to a battery. When the operation magnitude of an acceleration pedal is small, the current flowing through the base decreases. Therefore, the generator generates more electric energy. Along this condition, the generator regulates the rotation of the turbine in higher degrees. Consequently, the turbine becomes less rotatable. As a result, as it becomes difficult for the intake air to flow through the turbine, the flow volume of intake air to be introduced into the combustion chambers decreases.
