摘要： For suppression of knocking in an internal combustion engine, an engine vibration level is periodically generated at predetermined time intervals on the basis of an output signal of a knocking sensor which is installed for detecting the engine vibration, the engine vibration level thus generated being compared with a preset sensor failure level. When the vibration level remains lower than the preset sensor failure level successively throughout a period corresponding to a predetermined number of engine cycles, a knocking sensor failure indication signal is generated to thereby allow knocking control to be precautionarily performed for the safety of the engine operation.

摘要： Method and apparatus for detecting a failure of a pressure sensor provided in association with a cylinder of an internal combustion engine for detecting the pressure therein. Decision as to occurrence of a failure in the pressure sensor is made on the basis of the cylinder pressure detected by the pressure sensor through comparison with a prescribed reference value or range. Failure of the pressure sensor is determined if the detected cylinder pressure deviates from the reference value or range by a predetermined amount. Upon detection of a pressure sensor failure, an engine control parameter such as ignition timing for controlling the associated cylinder in dependence on the pressure sensor output is set to a fixed value or the operation of the cylinder is stopped.

摘要： A control apparatus can electronically control the operation of a multi-cylinder engine in a precise manner. A first signal generator 1 and a second signal generator 2 are provided on a camshaft operatively connected with a crankshaft for generating a cylinder identifying signal SC and a reference position signal ST, respectively, in synchronism with the rotation of the camshaft. A pulse signal generator 6 or 12 is provided on a crankshaft for generating a pulse signal P of a high frequency in synchronism with the rotation of the crankshaft. The reference position signal ST contains a series of pulses each indicative of a first and a second reference position for each cylinder which are modified by counting the number of pulses in the pulse signal P to provide exact reference positions. A microcomputer 5 or 15 controls the engine based on the exact reference positions of each cylinder thus obtained. In a modified form, instead of two signal generators 1, 2, a single signal generator 11 is employed which is provided on the camshaft for generating a single signal SCT which contains a series of pulses having different pulse widths corresponding to different cylinders. The signal SCT and the pulse signal P are input via an AND gate 17 to a counter 16 where the number of pulses in the pulse signal P during the pulse width of each pulse of the SCT signal is counted for cylinder identification.

摘要： A method and an apparatus for suppressing knocking in an internal combustion engine are disclosed therein. Vibrations of the engine are detected periodically by a knocking sensor installed on the engine. Decision is made as to whether or not the vibration level as detected exceeds a predetermined value. In dependence on the result of the decision, the vibration level is averaged with a first or a second significance ratio which differ from each other and which are previously determined in consideration of variations in the vibration level brought about by degradation of the knocking sensor in the course of time lapse or by an engine operating state. A mean value obtained through the averaging processing is utilized as a basis for determining a threshold level for comparison with the vibration level for making decision as to the occurence of knocking. Upon detection of knocking, a retarded ignition control signal for retarding the ignition timing of the engine is generated to thereby suppress the occurrence of knocking. Because the threshold level reflects variations in the vibration level over time or variations in the engine operating state, knocking can be identified with improved reliability. Major portions of the apparatus can be implemented by using a microprocessor, whereby hardware requirement and expenditure can be mitigated significantly.

摘要： A knock suppressing apparatus for an internal combustion engine includes an amplifier that amplifies the output signal of a knock sensor for sensing engine vibrations. A vibration level signal and a threshold signal are generated based on the amplifier output signals, and knocking is detected by comparing the vibration level signal and the threshold signal. The gain of the amplifier is varied in accordance with an operating condition indicative of the noise level of the engine so as to maintain the vibration level signal and the threshold signal within prescribed ranges suitable for knock determination. In one form of the invention, when the amplifier gain is varied, the threshold signal is also varied at substantially the same time and by substantially the same percentage as the amplifier gain.

摘要： A knock sensing apparatus for a multi-cylinder internal combustion engine has a knock sensor that generates an electrical output signal corresponding to vibrations of the engine. A level indicating means generates a first level signal indicating the level of the output signal of the knock sensor during a first period at least partially coinciding with the power stroke in a cylinder of the engine and a second level signal indicating the level of the output signal of the knock sensor during a second period. An averager forms an average of the second level signal over a prescribed period, and a threshold calculator calculates a threshold based on the average. A comparator compares the first level signal and the threshold and generates a signal indicating knocking when the first level signal exceeds the threshold.

摘要： A knock control apparatus and method for an internal combustion engine serves to simplify hardware components employed to reduce the load thereon, and hence minimize the cost of manufacture while improving the freedom of control of an engine control unit. Vibrations of a cylinder are sensed to generate a vibration level which is then averaged to provide an average value. A knock determination threshold is generated based on the average value. The vibration level is compared with the threshold for determining whether knock is taking place in the cylinder. When the vibration level exceeds the threshold, engine control parameters are controlled in a direction to suppress knocking in the cylinder. Preferably, the averaging of the vibration level comprises averaging the vibration level to provide a first average value, and averaging the first average value to provide a second average value. Preferably, the generation of a vibration level comprises generating a first vibration level and a second vibration level at a first and a second reference crank position, respectively. A knock determination threshold is generated based on the second vibration level. A knock determination signal is generated based on a difference between the first vibration level and the knock determination threshold.
