摘要： PURPOSE: To prevent a catalyst container from destroying by an excessive heat by equipping a thermostatic sensor for a three-way catalyser disposed on the way of an exhaust pipe of an air fuel ratio controller so as to interrupt an opening or closing control for an air supply valve when a cylinder accidentally catches fire.
CONSTITUTION: Disposed on the way of an exhaust passage 24, a three-way catalyser 30 is equipped with a thermostatic sensor 32. When the three-way catalyser is excessively heated by an accidental fire of a cylinder, the thermostatic sensor 32 sends such an indication signal to a controller 28 as to interrupt an opening or closing motion of an air supply valve 22 placed under a control of an air fuel ratio sensor 26 and keep the air supply valve 22 opened at a certain degree. The output of the air fuel ratio sensor may be maintained leaned so that the temperature of a catalyst stops rising as high as heated.

摘要： PURPOSE:To enable a small-capacity switching element to be used by increasing a current flowing through the coil of a solenoid valve by decreasing the resistance value of a resistor for current detection. CONSTITUTION:A comparator 12 compares the output (b) of an integrator 25 with the output (c) of an oscillator 20 and, when the output of the integrator is greater, outputs a high-level signal. Therefore, when an amplifier output voltage (f) corresponding to a current flowing through a coil 14 is lower than, for example, a control input voltage (a), the integral output (b) of the integrator 25 rises on the average and the conduction time of a transistor 17, therefore, increases, increasing the current flowing through the coil 14. Thus, the current is supplied to the coil 14 in proportion to the control input voltage (a).

摘要： PURPOSE: To detect a surge current with high accuracy, by separately providing a surge current detecting resistance.
CONSTITUTION: When voltage Vd of an output terminal (d) of a comparator 2 is in a high level, a Tr7 conducts, a current is supplied to a coil 4 of a solenoid valve, voltage Ve appears in an terminal (e) of a driving current detecting resistance 6, and voltage Vf is obtained through an operational amplifier 18. When voltage Va of a control input terminal (a) has been varied, an integrator 15 integrates in the ratio corresponding to a deviation of this voltage and Vf, and outputs voltage Vb to an output terminal (b). On the other hand, an output Vc from a triangular wave oscillator 10 is compared with Vb, and in case when Vb is larger, the Tr7 is turned on. On the contrary, in case when Vc is larger, a low level signal is outputted and the Tr7 is turned off. In this case, a surge current generated in the coil 4 of the solenoid valve flows through a surge current detecting resistance 31 and a diode 16, and voltage Vg generated in the resistance 31 in that case is inputted to the amplifier 18 through a voltage divider.
