摘要： An angular position detector mounted within an engine ignition distributor for detecting an angular position of a rotary shaft. The detector comprises a detecting element disposed about the rotary shaft for generating a detection signal corresponding to an angular position of the rotary shaft and a processing circuit disposed around the rotary shaft for processing the detection signal from the detecting element. The detecting element and the processing circuit are connected by an electrical conductor member which is arranged at a position sufficiently remote from the rotary shaft for reducing an undesirable effect of a high voltage which may appear in the rotary shaft.

摘要： A distributorless ignition system using a dual-spark ignition coil generates a signal indicative of which of the two cylinders associated with the dual-spark coil is operating in its power stroke by means of a single detector connected to a predetermined one of the cylinders. The output of the detector is fed to a sample and hold circuit which supplies the peak value from the detector to the control unit of the ignition system where the peak value is evaluated and identified by comparison to a previously obtained peak value. The control unit indicates that the predetermined cylinder is in its power stroke when the detected peak value signal is at its higher level. Conversely, when the peak value signal is at its lower level the control unit determines that it is the other of the two cylinders which is in its lower stroke and signals this accordingly.

摘要： The method and apparatus allows the detection and indication of anomalies in the operation of the ignition system of an internal combustion engine including a plurality of spark plugs, each of which receives a periodic high-voltage pulse output by a high-voltage generator in operation. The method includes the steps of:detecting the pulses generated by the high-voltage generator,comparing the peak values of each pulse detected with first and second threshold values, andproducing a perceptible signal when the peak values of the high-voltage pulses fall outside the acceptable range defined between the threshold values.

摘要： A signal control generator for a multi-cylinder internal combustion engine has a position sensor which generates output pulses which indicate prescribed rotational angles of the crankshaft of the engine for each cylinder. The output pulse for a prescribed reference cylinder of the engine is shorter than the pulses for the other cylinders. The reference cylinder is recognized by comparing the pulse width or the duty cycle of each pulse with the pulse width or the duty cycle for previous pulses corresponding to other cylinders of the engine. The period between consecutive output pulses is used to control the ignition timing of the engine.

摘要： A microprocessor controlled digital engine analyzer receives analog input signals from an engine being analyzed, engine parameter data entered via a keyboard, and function data, selecting one of several operating modes for the analyzer and which information is to be displayed, entered via the keyboard, and displays on a CRT screen the selected information such as cylinder firing order, RPM, Dwell, KV and DC volts, alphanumerically, information such as primary and secondary ignition and voltage, alternator and fuel injector information through the use of continuous waveform patterns, and additional information pertaining to Dwell, KV and Cylinder Shorting through the use of bar graphs. The waveform pattern data derived from the analog input signals is stored in a dual bank waveform memory and read out for display on the CRT screen under hardware control, and address data representing alphanumeric data and screen formats for the various operating modes to be displayed is stored in a dual bank display memory for application to a character generator, a bank switching arrangement being used for both the waveform memory and the display memory to enable the banks of each memory to be alternately written to and read from. A main microprocessor receives and processes analog input signals, other than the waveform pattern signals, and a display microprocessor receives numerical data from the main microprocessor and causes display of the numerical data on the CRT screen.
