摘要： An ignition range detector for an internal combustion engine is disclosed, in which at each combustion of the internal combustion engine, a pressure signal of a pressure sensor for detecting the pressure in a cylinder is integrated by a signal associated with the crank angle to produce an area S.sub.1 +S.sub.2 presenting the combustion state. At the same time, the pressure signal for a hypothetical case of misfire under the same condition is integrated to produce an area S.sub.1. It is decided whether the ratio (S.sub.1 +S.sub.2)/S.sub.1 is higher than a predetermined value .alpha. or not thereby to detect an ignition range always stably regardless of the operating conditions of the internal combustion engine including the load thereon.

摘要： An ignition timing control system for an internal combustion engine in which an angular position of the internal combustion engine is detected, and on the basis of the signal thus obtained by detection, the ignition timing of the internal combustion engine is determined by calculation in a computing device. A knocking condition is judged by a detection signal produced from a knocking detector of the internal combustion engine, and the ignition timing is corrected by the judgement of knocking. In view of the fact that the knocking occurs only during a certain period of the driving cycle of the internal combustion engine, a knocking condition is judged by comparing a detection signal produced from the knocking detector during the time in the absence of knocking with a detection signal produced during the time in the presence of knocking.

摘要： In normal load operating conditions of the engine, an ignition timing control unit produces an ignition timing signal in accordance with the rotation speed and intake negative pressure of the engine. In transitions, for example, from idling operation to normal load operation, and vice versa, an ignition timing delaying circuit in the ignition timing control unit produces a correction signal by detecting whether or not the throttle valve is fully closed. When the correction signal is produced, the ignition timing control unit produces corrected ignition timing signal so that, in the transient periods of operation, the ignition timing is gradually changed to a predetermined ignition timing.

摘要： A deteriorated condition detecting apparatus for an oxygen concentration sensor used in an air-fuel ratio feedback control for an internal combustion engine comprises a reference oxygen concentration sensor mounted in proximity to the oxygen concentration sensor used for the air-fuel ratio feedback control and a discriminator for comparing duty factors of output signals from those two sensors to determine a deteriorated condition of the oxygen sensor. The discriminator determines the deteriorated condition when the duty factor of the sensor under test deviates from the duty factor of the output signal of the reference sensor by a predetermined amount. It converts the outputs of the respective sensors to square wave signals and integrates one of the levels of the square wave signals to determine the duty factors, and differentially amplifies the integrated signal to produce a differential output signal, which is then compared with a predetermined level to determine whether there exists a deviation of the duty factor corresponding to the deteriorated condition.

摘要： An air-fuel ratio adjusting apparatus for an internal combustion engine employing a gas sensor whose electric characteristic changes rapidly at near the stoichiometric air-fuel ratio so as to maintain the air-fuel ratio of mixture at any desired air-fuel ratio other than the stoichiometric one. A bypass valve is mounted in a bypass passage for supplying additional air to the portion of the carburetor downstream of its throttle valve. In response to the sensed signal from the gas sensor mounted in the exhaust pipe, the bypass valve is opened or closed to increase or decrease the amount of additional air. Taking advantage of the fact that there exists a delay of a definite time period between the time of generation of a sensed signal from the gas sensor and the time that the sensed signal produces an effect on the excess air factor of the exhaust gases, by causing the opening and closing speeds of the bypass valve to differ from each other, it is possible to maintain the air-fuel ratio of mixture constant within a wide range of air-fuel ratios.
