Abstract:
(EN) A pressure detecting device which detects the combustion pressure in an internal-combustion engine includes: a piezoelectric element 10 which outputs a charge signal corresponding to the pressure in a combustion chamber; and a mounting board 210 on which are mounted an integrating circuit 212 which integrates the charge signal output by the piezoelectric element 10, and amplification circuit 213 which amplifies a voltage signal obtained by integration. On the mounting board 210 are provided a power receiving terminal 211a which receives a power supply voltage from a control device, an output terminal 211b which outputs an output signal to the control device after amplification, and a grounding terminal 211c for making the ground of the control device and the mounting board 210 common. Furthermore, in the mounting board 210, the grounding terminal 211c, and grounding terminals of the integrating circuit 212 and the amplification circuit 213 are connected by way of grounding ferrite beads 216.
(FR) L'invention concerne un dispositif de détection de pression qui détecte la pression de combustion dans un moteur à combustion interne, et qui comprend : un élément piézoélectrique (10) qui délivre en sortie un signal de charge correspondant à la pression dans une chambre de combustion ; et une carte de montage (210) sur laquelle sont montés un circuit d'intégration (212) qui intègre le signal de charge délivré en sortie par l'élément piézoélectrique (10), et un circuit d'amplification (213) qui amplifie un signal de tension obtenu par intégration. Sur la carte de montage (210) sont disposées une borne de réception électrique (211a) qui reçoit une tension d'alimentation électrique provenant d'un dispositif de commande, une borne de sortie (211b) qui délivre en sortie un signal de sortie au dispositif de commande après amplification, et une borne de mise à la masse (211c) pour rendre commune la masse du dispositif de commande et de la carte de montage (210). En outre, dans la carte de montage (210), la borne de mise à la masse (211c), et les bornes de mise à la masse du circuit d'intégration (212) et du circuit d'amplification (213), sont reliées par des billes de ferrite de mise à la masse (216).
(JA) 内燃機関の燃焼圧を検出する圧力検出装置は、燃焼室内の圧力に応じた電荷信号を出力する圧電素子10と、圧電素子10が出力する電荷信号を積分する積分回路212および積分で得られた電圧信号を増幅する増幅回路213を実装してなる実装基板210とを有する。この実装基板210には、制御装置から電源電圧を受電する受電端子211aと、制御装置に向けて増幅後の出力信号を出力する出力端子211bと、制御装置および実装基板210のグランドを共通化するための接地端子211cとが設けられる。そして、実装基板210において、接地端子211cと積分回路212および増幅回路213の各接地端とを、接地用フェライトビーズ216を介して接続する。
