Abstract: An engine control system executes fuel injection and ignition in accordance with a detected engine rotational position. The engine control system has a crank sensor on a crankshaft and a cam sensor on a camshaft. The crank sensor generates a first reference position signal at intervals of 360 degrees CA. The cam sensor generates a second reference position signal at a rotational position different from the crank sensor. The engine control system also includes a means for controlling the engine on the basis of the first reference position signal and a means for controlling the engine on the basis of the second reference position signal. When the engine is started, either of the signals is detected so that it is possible to control the engine in accordance with a rotational position of the engine early. The cam sensor is also used in control of a variable valve timing unit.

Abstract: A memory stores and holds both the number of crankshaft angle pulse signals occurring after detecting a reference portion when an engine stops and data relating to whether the reference portion which is supposed to be next detected upon re-start of the engine is a reference position of the camshaft. When the engine is re-started, it is determined whether a reverse rotation of the crankshaft across the reference position happened by comparing a predetermined value with the total obtained by adding the number of pulse signals stored in the memory and the number of pulse signals occurring until the reference portion is first detected again. When such reverse rotation happened, the reference position of the camshaft is shifted by 360.degree. CA. Therefore, regardless of whether such reverse rotation across the reference position happened or not, the engine timing cycle is again precisely synchronized.

Abstract: A knock sensing apparatus for an internal combustion engine which can detect a failure in a knock sensor signal system correctly even when a changeover operation due to hardware is performed at a place between a knock sensor and a band pass filter. In this knock sensing apparatus, the failure detection by a failure detecting circuit for detecting a failure in a signal system from knock sensors is invalidated for a predetermined period after one of the knock sensors has been changed over to the other knock sensor, or one of two kinds of pass bands of a band pass filter has been changed over to the other pass band, to prevent a decrease in failure detection accuracy due to the signal delaying action of the switched capacitor filter.

Abstract: An ignition timing control system for an internal combustion engine includes a basic ignition timing calculating unit for calculating a basic ignition timing of the engine and a low limit ignition timing calculating unit for calculating a low limit ignition timing of the engine, both being calculated according to an operating state of the engine. The system includes a retardation angle calculating unit for calculating a retardation angle that is retarded from the basic ignition timing. It also includes an advance angle calculating unit for calculating an advance angle that is advanced from a value corresponding to the low limit ignition timing depending on whether knocking is occurring in the engine. An operating state predicting unit is included for predicting an operating state of the engine where knocking is likely to occur. The system also includes an ignition timing control unit for controlling the ignition timing separately depending on whether a knocking is likely to occur in the engine.

Abstract: A signal rotor 6 rotates in synchronism with a crank shaft of the internal combustion engine. A pickup sensor 7 is disposed in a confronting relation to the signal rotor 6 to generate an angle signal S1 proportional to rotation of the internal combustion engine. An ignition signal producing means (31, 32) calculates an ignition timing on the basis of the angle signal S1 and generates an ignition signal (S41, S42) for igniting the internal combustion engine. A time mask means monitors a parameter representative of a battery voltage Vs, and prohibits the angle signal S1 from entering into the ignition signal producing means for a predetermined time in response to a detection of a predetermined amount fluctuation of the parameter.

Abstract: A knocking vibration detecting unit (1) and a knock deciding unit (c) are integrated, and the communications of a knock intensity between the knock deciding unit (c) and an engine controlling microcomputer (7) are carried out in combination of a change from the previous value of a signal line level. In the engine controlling microcomputer (7), the ignition timing is controlled by a predetermined retard angle in case of combination of no change of the present read signal line level from the previous signal line level.Thus, an internal combustion engine is prevented from any damage by relieving a failure without fail when a signal line (10) is troubled, while minimizing the influences of noises and reducing the space and size of an ECU.

Abstract: A knock control system for an internal combustion engine derives a knock intensity indicative value Vpi from an output of a knock sensor and decides presence or absence of an engine knock by comparing the knock intensity indicative value Vpi and a knock decision level V.sub.KDi for controlling a knock control factor such as an ignition timing based on the decision. The system derives a value Si corresponding to a standard deviation of a distribution of a substantially logarithmic conversion value of the knock intensity indicative value Vpi, and a value V.sub.Mi corresponding to a median value of the above-noted distribution. The system derives the knock decision level V.sub.KDi based on the value Si and the value V.sub.Mi when the value Si is within a predetermined range. On the other hand, when the value Si deviates from the predetermined range, the system derives the knock decision level V.sub.KDi based on the value V.sub.
