Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To optimize the control waveform used in the air-fuel ratio feedback control, suppress torque variation, and enhance the exhausting characteristics. SOLUTION: An electronic control device (ECU) 30 calculates the air-fuel ratio feedback correction factor for performing skip correction and integral correction on the basis of a sensing signal (sensor voltage) VO given by an oxygen sensor 11 and corrects the fuel injection amount (time) using the obtained correction factor.

Depending upon the manner to introduce the estimate skip amount, it is possible to deviate the controlling center of the air-fuel ratio feedback correction factor to the rich or lean side while the characteristics concerning the amplitude or frequency of the controlling waveform are maintained.

Abstract: PURPOSE:To supply an electric current through a noncontact part by a method wherein a secondary coil laid along the movement route of a mobile body and surrounding one part of an iron core in a noncontact state is connected to the mobile body and the other part of the iron core is surrounded by a primary coil. CONSTITUTION:A secondary coil 2 in which one part of an iron core 3 forming a closed magnetic circuit is laid along the movement route of a mobile body surrounding one part of the iron core 3 in a noncontact state is connected to the mobile body, and the other part of the iron core 3 is surrounded by a primary coil 1. Consequently, when an AC current is made to flow to the primary coil 1, a magnetic flux is generated in the closed magnetic circuit of the iron core 3, electromotive force is induced in the secondary coil 2, and its AC electric power is used by the mobile body. Since the secondary coil 2 always surrounds the iron core 3 in a noncontact state, the supply of the electric power is continued even when the mobile body is moved on the movement route along the iron core 3. Thereby, the electric power can be supplied through a noncontact part without using a contact-type current collection arm or the like.
