摘要： PURPOSE:To perform rapid detection of deterioration of performance of an adsorbent and to perform proper fail safe by calculating a quantity of adsorptive heat of an adsorbent through detection of an exhaust gas temperature difference between the inlet part and the central part of the adsorbent and an amount of intake air, and effecting diagnosis of adsorbing capacity. CONSTITUTION:Exhaust gas from an engine 1 is guided to a muffler 8 through exhaust gas pipes 7a and 7b in which three-dimensional catalysts 9a and 9b, respectively, are located. A bypass passage bypassing an exhaust gas main passage 22 is branched in a position situated downstream from the muffler 8 and an adsorbent 24 is located in the branched passage to adsorb hydrocarbon. Through control of valves 25, 27, and 28, adsorption by the adsorbent 24 and introduction of eliminated HC to an intake system are controlled by a control unit 10. Further, a total quantity of adsorption heat of the adsorbent 24 is calculated based on a temperature difference between an inlet exhaust gas temperature sensor 41 and an outlet exhaust gas temperature sensor 43 or a central exhaust gas temperature sensor 42 and an amount of intake air, and through comparison of the calculated result with a target total quantity of adsorption heat, the presence of a trouble is decided according to the magnitude of the compared result. Deterioration of performance is rapidly detected through a self- diagnosis.

摘要： PURPOSE:To obtain a small and inexpensive rotational position detector by discriminating cylinders with a microcomputer empolying a signal integrating a cylinder signal with a cylinder discrimination signal and an angle signal. CONSTITUTION:With the rotation of a signal rotor 1, a voltage signal generated in a pickup coil 3 serves as a signal of waveform G1 with a waveform shaping circuit 21. This signal is given a cylinder discrimination signal for a cylinder discrimination tooth crest 5 of a rotor 1 and signals #1-4 of cylinder signal tooth crests 6-9 overlapping them. Likewise, a signal N due to the rotor 2 is obtained at an output 25. A signal processing circuit 23 uses the signal N from the signal G1 to make a cylinder signal G2 clear of the cylinder discrimination signal. Then, a microprocessor 27 uses the signal G1, the signal N and the signal G2 to control the engine. When the control in terms of the cylinder or the cylinder group, for example, at the start of the engine is not needed, the engine control is performed by the signals N and G2 while when such a control is needed, the signals G1, N and G2 are used to control the engine conducting the discrimination of cylinders.

摘要： PURPOSE:To control the combustion state of an engine with high precision through such simple constitution that only a microwave circuit and a photoelectric converting circuit are added to an ignition plug. CONSTITUTION:The ignition plug 4 has a coaxial circuit structure which propagates a microwave signal, and th tip part of the center conductor has a high- frequency antenna function. Further, an optical fiber for guiding light out of a combustion chamber is incorporated in the center and a piezoelectric element as a knock sensor is provided. Microwave resonance before and after of a top dead point of a piston is measured by the antenna function and led to a top dead point detecting circuit 17, and a light signal originating from a combustion flame is guided out through the optical fiber and converted into an electric signal, which is led to a combustion flame color detecting circuit 19. Further, the piezoelectric element detects a knocking signal, which is led to a knocking detecting circuit 18. Thus, the amount of fuel injection, timeing, air suction amount, etc., are controlled collectively by said detection.

摘要： PURPOSE:To remove completely the influence of rotational variation which has a larger period than a gear signal by correcting the angle value of a timing signal for analysis on the basis of section times detected between respective gears. CONSTITUTION:A timer TDC latch 13 and a counter TDC latch 19 latch the current time and the counted value of a timing signal counted so far. A timer gear latch 12 latches the counted value of the current timing signal when the 1st gear signal is generated, and a latch 15 outputs the time of the timing signal right before the gear signal as a signal. A latch signal generator 14 switches the output signal from the latches 15 to 16. A CPU calculates the section time between the latch signal and gear signal and stores it. Similar processing is performed when the 2nd gear signal is generated. The CPU calculates and stores the angle of each timing signal. Those angle signals are corrected on the basis of the gear signal.

摘要： PURPOSE:To detect angles by an inexpensive sensor with few errors, by using a rotary body, wherein one or more teeth are omitted or angle data are not generated at an equal interval, and comparing the continuous angle data by a specified judging means. CONSTITUTION:A rotary angle sensor is constituted of a rotor 10a and a pickup coil 10b. In Figure A, one of teeth with an equal interval is omitted. In Figure B, the intervals between the teeth are partially unequal. The signal, which is detected by the pickup coil of the rotary sensor is shaped by a well known waveform shaping circuit in a control circuit. Then, the waveform shown in the Figure is obtained. The continuous angle data are compared by a judging means, and a reference crank position is detected based on the result. Thus the angle can be detecred by the inexpensive sensor with few errors.
