摘要： A flow quantity valve controller includes a unit for positioning so that a phase of a stepper motor becomes a predetermined phase when a motor shaft making a linear move with rotation of the stepper motor is pulled most into the stepper motor side. When the motor shaft is pulled most into the stepper motor side, a flow quantity valve controller changes a stepper motor drive signal to a drive signal corresponding to a predetermined phase.

摘要： A cylinder identifying system for an internal combustion engine enables fuel injection and ignition controls for individual cylinders to be speedily performed upon starting of engine. A cylinder identifying means (10) operating on the basis of a crank angle signal (SGT) and a cam signal (SGC) includes a pulse signal number storage means (12) for dividing an ignition control period of each cylinder into plural subperiods for counting for storage signal numbers of specific pulses generated over plural subperiods, and a subperiod discriminating means (14) for determining discriminatively a sequential order of the plural subperiods on the basis of combinations of the numbers of the specific pulses generated during the plural subperiods. The combinations of the numbers of specific pulses generated during the plural subperiods differ one another correspondingly to the plural subperiods independently from the start points thereof. The cylinder identifying means (10) identifies the individual cylinders on the basis of results of determination made by the subperiod discriminating means (14) independently of positional relationships between the storage start points and the subperiods.

摘要： A deterioration detecting apparatus for catalytic converter is provided to surely detect deterioration of a catalytic converter. In the deterioration detecting apparatus for catalytic converter, an electronic control unit decides whether or not a catalyst is activated in the catalytic converter for removing injurious ingredients from an exhaust gas of an engine, and the electronic control unit decides the deterioration of the catalyst only when it decides that the catalyst is activated. It is thereby possible to avoid erroneous decision of the deterioration since the deterioration of the catalyst is not decided when the catalytic converter is not activated.

摘要： An exhaust gas recirculation control system includes a stepping motor driven valve for controlling the flow rate of exhaust gas through a recirculation pipe of an internal combustion engine, and arithmetic circuitry for calculating the exhaust gas recirculation flow rate in dependence on the operating state of the engine.

When a rapid response is required, the two-phase excitation driving scheme is put into effect, with the one/two-phase excitation driving scheme being adopted when high resolution is required.
