摘要： A control system for a hybrid vehicle including an internal combustion engine, a drive shaft driven by the engine, a generator for converting kinetic energy of the drive shaft to electrical energy to generate electric power, and an electrical storage device for storing electrical energy output from the generator, wherein idling of the engine is detected. An amount of electrical energy to be regenerated by the generator during the idling of the engine is calculated. An output from the generator is calculated based on the amount of electrical energy to be regenerated by the generator. An amount of intake air supplied to the engine is controlled in a manner such that the amount of intake air to be supplied to the engine is increased when the generator regenerates electrical energy during the idling of the engine. And an air-fuel ratio of a mixture supplied to the engine is controlled to a leaner value than a stoichiometric value during the idling of the engine.

摘要： A control system is provided in an internal combustion engine in which a valve timing such as an opening time point and lift amount of an intake valve can be switched to a low-speed or high-speed valve timing within a lean-burn control range established in accordance with the operational state, such as an intake pipe internal absolute pressure and an engine revolution number of the engine, wherein an air-fuel ratio of an air-fuel mixture supplied to the internal combustion engine is enriched for a predetermined time when the valve timing is switched from the low-speed valve timing to the high-speed valve timing while carrying out a lean-burn control. Thus, even when the valve timing is switched over to the high-speed valve timing, the lean-burn control is carried out to prevent a misfiring or an unstable combustion state caused when the valve timing is switched during the lean-burn control, thereby providing a reduction in emission and an enhancement in drivability, while enhancing the specific fuel consumption.

摘要： A method of determining the deterioration of an oxygen concentration sensor for an internal combustion engine. The oxygen concentration sensor includes at least one oxygen concentration sensor element having an oxygen-pumping element and a cell element each composed of a member of a solid electrolytic material having oxygen ion-conductivity, and a pair of electrodes having the member interposed therebetween, and a current-detecting resistance serially connected to the oxygen-pumping element to form a series circuit. A voltage having a magnitude corresponding to a difference between a voltage produced between the electrodes of the cell element and a predetermined reference voltage is applied to the series circuit, and pumping current is detected from a voltage developed across the current-detecting resistance. The predetermined reference voltage is changed from a first predetermined value to a second predetermined value, followed by detecting a difference between a value of said pumping current detected when the predetermined reference voltage assumes the first predetermined value and a value of the pumping current detected when the predetermined reference voltage assumes the second predetermined value. It is determined that there is deterioration in the oxygen concentration sensor when the difference is equal to or greater than a predetermined reference value.

摘要： An oxygen concentration detecting device includes at least one oxygen concentration detecting element formed by an oxygen-pumping element and a cell element, composed of an oxygen ion-conductive wall, separating a pair of electrodes. The oxygen-pumping element and cell element define a gas diffusion chamber. A current detecting resistance forms a series circuit with the oxygen-pumping element. A voltage applying circuit applies to the series circuit an output voltage corresponding to the difference between a voltage between the electrodes of the cell element and a first reference voltage. An output detecting circuit outputs a voltage signal corresponding to a value of pumping current flowing through the resistance. An operational amplifier has a non-inverting input terminal supplied with a second reference voltage, an inverting input terminal connected to one end of the resistance, and an output terminal connected to the other end of the resistance. The output detecting circuit detects a first voltage at the one end of the resistance and a second voltage at the other end and outputs the voltage signal corresponding to the difference between the detected first and second voltages. The output detecting circuit corrects the voltage signal based upon the first and second voltages which are obtained in a state where no pumping current is supplied to the resistance. Electrodes of the oxygen-pumping element and the cell element are connected together within the gas diffusion chamber or within the basic body of the sensor body.
