Title: Detecting apparatus of inner-cylinder pressure
Inventor: IWATA TOSHIO
IPC: G01L23/00
Filed: 1988-03-08
Abstract: PURPOSE:To detect the state of combustion inside a cylinder, by detecting a peak position of a combustion pressure by means of a detection signal of a peak position detector, while detecting a timing value thereof. CONSTITUTION:A waveform of a combustion pressure inside a cylinder is once stored in a waveform memory 1. Starting at a time when a piston comes to a compression to dead center, subsequently, the waveform stored in the memory 1 is read out, and the waveform read out in a sequence reverse to the one in which it is inputted is inputted to one input of a subtracter 2. The same waveform as that inputted to the memory 1 is inputted to the other input of the subtracter 2 and a subtraction of waveforms is executed therein. From an output waveform therefrom, a timing value (thetapmax) is detected by a peak position detector 3. Meanwhile, a pressure peak value Pmax at the time of detection of a peak position is obtained from a latch circuit 4 which latches the waveform inputted to the memory 1. By detecting the peak value of the waveform and the timing value thereof in this way, the state of combustion inside the cylinder can be detected.

Filed: 1980-04-24
Abstract: PURPOSE: To reduce abnormal voltages in the ignition circuit of an igniter employing no distributor, by providing chip-laminated high-voltage diodes and setting the breakdown voltage of the diodes and chips at prescribed levels respectively.  
     CONSTITUTION: An igniter comprises diode-chip-laminated high-voltage diodes A 1 WA 4  which can be used in the backward breakdown region. The breakdown voltage of the diodes A 1 WA 4  is set 1.1W1.8 times higher than the maximum discharge start voltage of a spark plug. The resistivity of the N type or P type layer of a P + NN +  type or P + PN +  type silicon element as a diode chip 7 is adjusted so that the mean breakdown voltage per diode chip is set at 400W850V. Since the backward breakdown resisting capacity is thus set high, load due to a very sharply rising high voltage is endured. Therefore, property deterioration and breakdown are avoided.
