摘要： A vibrator having a resonant frequency within a knocking frequency range forms a part of a magnetic path. The vibrator vibrates in response to the vibration of an internal combustion engine and this changes the reluctance of the magnetic path. The change in the reluctance is sensed by a coil to detect the presence of knock. The vibrator is enclosed with a damper substance consisting of a liquid or sol substance having viscosity of flow properties so that the vibration of the vibrator is restricted and the Q of the resonance characteristic of the vibrator is deteriorated, thus increasing the substantial range of frequency detection of the apparatus. If necessary, the damper substance is heated to maintain its viscosity at a predetermined value.

摘要： A gas component detector has a detector element of a metal oxide held on one end of a ceramic body. The detector element is electrically connected to a pair of electrodes and the pair of electrodes are in turn welded to a pair of sub-lead-lines to deliver a detected electric signal from the detector element. The pair of electrodes and sub-lead-lines are inserted in a pair of through holes of the ceramic body and the pair of electrodes are fixed by an inorganic adhesive within the through holes. The openings of the pair of through holes of the ceramic body at the opposite end with respect to the detector element are closed by a sealing material of an electrically insulating metal oxide.

摘要： An air flow amount adjusting system produces an air-fuel mixture of a desirable air-fuel ratio by controlling the direction of movement of a bypass valve mounted in an additional air supply pipe adapted to supply additional air into either the intake system or exhaust system of an internal combustion engine in accordance with an output signal produced from a gas sensor mounted in the exhaust system of the engine and indicative of the air-fuel ratio of the mixture supplied to the engine. A two-level mode signal whose threshold corresponds to the desired air-fuel ratio is produced in accordance with the output signal of the gas detector. After the two-level mode signal has changed from one level to the other level, the movement of the bypass valve is stopped for a certain period of time. If desired, the stopping period of the bypass valve may be changed in accordance with the temperature of the engine.

摘要： An air-fuel ratio controlling system for an internal combustion engine including a control circuit for controlling, in accordance with a detected air-fuel ratio, the operation of a drive motor of a control valve mounted in an additional air supply passage. The control circuit includes a timing pulse generator for generating timing pulses synchronized with a running speed of the engine and thus the control valve is intermittently rotated by a predetermined amount in response to the timing pulses. By increasing the frequency of the timing pulses during the periods of rapid acceleration and deceleration, a response to the change in the engine speed is further improved.

摘要： An air-fuel ratio adjusting system controls the amount of additional air supply through the bypass passage of the carburetor to ensure optimum engine operation even in a warming up condition of the engine. The air-fuel ratio adjusting system includes an air-fuel ratio sensor disposed in the exhaust manifold, a warm-up sensor for detecting the temperature of engine cooling water or engine block, and a control unit for providing a control signal to a driving motor for the bypass valve. The bypass valve is controlled so that the air-fuel ratio of the mixture becomes the stoichiometric one and at the same time, during the warming up condition, the maximum opening of the bypass valve is limited to a predetermined degree depending on the temperature of the engine.
