摘要： A system for controlling the air-fuel ratio in which the amount of fuel injected into the engine is controlled in accordance with the flow rate of air passing through an air intake pipe including a throttle valve for introducing the air into the engine and the engine operating conditions. A bypass of the air intake pipe is opened or closed to change the air-fuel ratio of the mixture to slightly richer and leaner sides of a basic air-fuel ratio, and the change of the engine output conditions based on the change of the air-fuel ratio is used to correct the air-fuel ratio in an optimum direction. On the basis of a parameter indicating the engine operating conditions such as the detection value of the intake pipe pressure, a control is made to introduce the air which passed through the bypass to one of the upstream or downstream portion of the throttle valve.

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： 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 bus interface unit receives first and second data sent out to a data bus and observes address values indicated on an address bus. The first and second data are written into first and second registers respectively. First and second address detection unit receive the address values observed by the bus interface respectively. The first address detection unit outputs a first detection signal when it detects an address value which corresponds with the value of the first data. The second address detection unit outputs a second detection signal, when it detects an address value having an increment from the first data, which corresponds with the value of the second data. A control unit raises the priority of one of the bus masters given a bus utilization right, during the period from a start of outputting the first detection signal to an end of outputting the second detection signal.

摘要： A receiver provides a differential signal of first and second signals as received serial data. A tracking circuit receives the received serial data and a clock signal to generate a synchronous clock signal based on the clock signal by tracking the received serial data. Then the tracking circuit generates a synchronous serial data synchronized with the synchronous clock signal. An idle detector receives the first signal and the second signal. Then the idle detector detects an idle period of the first and second signals to provide an idle signal. A memory stores the serial data in response to transitions in the synchronous clock signal. The memory provides the stored data in response to transitions in the clock signal. The memory stops storing based on a hold signal. A data protector generates the hold signal to provide the hold signal for the memory.
