摘要： Spark ignition timing of an internal combustion engine is oscillated on each side of a variable reference setting by varying it at stepwisely variable amounts during positive and negative swings and the resultant engine speed is detected in at least three successive phases. The detected engine speed values are compared one against each other to determine whether they satisfy one of two specified conditions. The variable reference is adjusted in a direction toward an optimum position depending on which one of the conditions is satisfied.

摘要： A gas sensor of constant-current type is used to detect a gas component in exhaust gases from an internal combustion engine so as to perform feedback control of air/fuel ratio of an air-fuel mixture supplied to the engine. In order to detect an air/fuel ratio which is richer than a stoichiometric value, a voltage applied to the gas sensor is set to a high value so that the gas sensor does not exhibit a constant-current characteristic. In the case it is desired to detect an air/fuel ratio which is either richer or leaner than the stoichiometric value, the voltage may be changed between the high value and a lower value at which the gas sensor exhibits a constant-current characteristic. Engine parameters are detected to determine whether the engine requires a rich mixture or a lean mixture, and the voltage may be changed as the result of such determination. An output current of the gas sensor is detected to ascertain air/fuel ratio so that air/fuel ratio is controlled to a desired value suitable for engine operating condition.

摘要： The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..

摘要： A method for controlling the ignition timing for the internal combustion engine is disclosed. When it is decided that the engine load is large on the basis of the engine number of revolutions per minute and intake pressure. If the engine is in the knocking condition, a step lead angle is added to the present lead angle value in the range between a set lead angle and a minimum lead angle. If the engine is not in the knocking condition, on the other hand, a step lead angle is subtracted from the present lead angle value in the above-mentioned range. By contrast, when it is decided that the engine load is small on the basis of the engine r.p.m. and intake pressure. The lead angle control of the present lead angle value is stopped so that the present lead angle is set at the above-mentioned set lead angle or the minimum lead angle value.

摘要： Supercharging pressure produced by a supercharger driven by the exhaust gasses is detected so that frequency of combustion in an internal combustion engine is reduced to lower the engine output power. In order to reduce the frequency of combustion, the number of times of fuel injection may be thinned out or fuel injection into one or some of the cylinders of the engine may be stopped for a given period of time. Alternatively, the frequency of ignition may be reduced or ignition in one or some of the cylinders may be stopped for a given period of time. The control of fuel injection and the control of ignition may be combined. A microcomputer may be used to perform the method according to the present invention where the microprocessor thereof is arranged to execute a main routine and an interrupt service routine. In the main routine, data related to the supercharging pressure is stored in a memory, and the interrupt service routine, fuel injection and/or ignition is performed. The prestored data is read out in the interrupt service routine to control fuel injection and/or ignition when supercharging pressure is above a given value.

摘要： A spark-ignition timing of the internal combustion engine is normally set at an MBT (minimum spark advance for best torque). However, when a knocking of the engine is detected by a vibration sensor fixed to the engine, the ignition timing is retarded with respect to the MBT by an angle corresponding to either a non-knocking limit retard angle or a maximum retard angle determined by engine operating conditions whichever is smaller.

摘要： A method of detecting knocking intensity of an internal combustion engine uses a detector for detecting vibration propagated within the engine and a first calculation circuit for obtaining an average value of vibration sensed by the vibration detector within a predetermined crank angle before the top dead center, and in which knocking is identified when the ratio between the above average value and the maximum value of vibration after the top dead center exceeds a predetermined value. This method also uses a second calculation circuit for obtaining a further average value of vibration detected by the vibration detector within a predetermined crank angle after the top dead center of the internal combustion engine, and a knocking discrimination circuit for generating a knocking indication output corresponding to the ratio between the average value of vibration before the top dead center obtained by said first calculation circuit and the average value of vibration after the top dead center by said second calculation circuit.

摘要： A lubricating apparatus for an internal-combustion engine comprises a detector for detecting whether the engine runs or not, a heat storage reservoir connected to lubricating oil outflow and inflow ports of the engine by a circular pipe system for storing the oil and maintaining its temperature, the heat storage reservoir being provided outside the engine, a hydraulic pump provided between the inflow port and the heat storage reservoir for controlling the supply of the oil stored in the heat storage reservoir to portions of the engine in response to a control signal, and a controller responsive to an output of the detector for producing the control signal to stop the hydraulic pump in order to maintain a temperature of the oil stored in the heat storage reservoir when the detector detects a stop of the engine and for producing the control signal to actuate the hydraulic pump to supply the oil, whose temperature is maintained by the heat storage reservoir, to the portions of the engine. The restarting of the engine is easily made because the oil is collected in the heat storage reservoir when the engine is stopped. In addition, the size of the engine is decreased, because the oil pan is omitted or part of the oil pan remains in the engine.
