摘要： A method and apparatus for controlling knock level in an internal combustion engine having knock induced vibrations and valve noises. Engine knock is decided when the knock induced vibration level exceeds at least one of the valve noise level and a limiting level. A basic value for the timing of ignition of the engine is calculated based upon engine operating parameters. The basic value is modified according to the result of the engine knock decision in a manner to operate the engine close to its knock level.

摘要： In a wire-cut EDM apparatus for cutting a workpiece (2) submerged in a processing tank (3) filled with a machining fluid (15), an opening (24) is made in the side wall of the tank through which an arm unit passes. A slide plate (14) also has an opening for passage of the arm unit and also provents leakage from the space between the opening 24 and the arm unit. In one preferred embodiment a fluid flow between the slide plate and arm unit is used to prevent fluid in the tank from escaping through the space between the slide plate (14) and the arm unit. Alternatively, a low frictional member may be placed between the arm unit and the slide plate for axially sealing the arm unit. Frictional resistance from movement of the lower arm unit is reduced and machining accuracy improved.

摘要： A throttle valve control system for an internal combustion engine electrically controls throttle valve angular position in order to control intake air flow rate through an air induction passage of an engine. The system employs an accelerator to produce a signal representative of a required or demanded output speed. Actual output speed is monitored by means of a speed sensor. The actual speed is compared with the output speed demand derived from the accelerator signal to obtain the difference therebetween. Feedback control is performed on the basis of the calculated difference so as to control the throttle valve angular position to increase or decrease the actual output speed toward the speed demand value.

摘要： A fuel injection system for an automotive internal combustion engine equipped with a fuel cut off control signal generator comprises a smoothing circuit which smoothes a fuel cut off control signal produced in response to engine parameters. The flow rate of fuel injected via injection valves is controlled in accordance with the pulse width of a valve energization signal where the pulse width thereof is further controlled by the voltage of the fuel cut off control signal so that the fuel flow rate decreases and increases exponentially in the same manner as the voltage of the fuel cut off control signal when the fuel flow is cut off and is reestablished. Two monostable multivibrators and two transistors are provided for selectively transmitting and blocking the fuel cut off control signal so as to prevent misfires of the engine when the fuel flow rate is below a predetermined value.

摘要： A reference voltage, which is compared with an output voltage of an exhaust gas sensor in a differential signal generator of an electronic closed loop air-fuel ratio control system, changes depending upon a mean value of an output of the exhaust gas sensor provided in an exhaust pipe extending from an internal combustion engine. Furthermore, the magnitude of the reference voltage is limited in such a manner as to be within a predetermined range, or in other words, the magnitude of the reference voltage is limited at at least one of an upper and a lower values thereof.

摘要： The temperature and pressure of the vapor generated in a vapor generating unit are so controlled that a fuel supply valve is opened for fuel delivery when the temperature or pressure drops below a predetermined lower limit and is closed when the temperature or pressure exceeds a predetermined upper limit, provided that a vehicle operator manipulable throttle valve is substantially in a fixed position. As the throttle valve is abruptly moved, an acceleration or deceleration signal opens or closes the fuel supply valve independently of the actual vapor temperature and pressure.
