Description
上記目的は、内燃機関のクランクシャフトと一体に回転し、外周面に複数の第１凸部を有するセンサプレートと、磁束に基づいて前記第１凸部の通過を検知することで、前記クランクシャフトの回転角を検出する回転角センサと、前記回転角センサに設けられ、前記回転角センサと前記センサプレートとの間に位置する磁束集中部と、を具備し、前記クランクシャフトとピストンとは連結され、前記センサプレートに最も近い前記ピストンの燃焼圧がピークとなる前記クランクシャフトの回転角に対して、前記センサプレートの周方向に所定角度ずれた位置に前記回転角センサが設けられ、前記磁束集中部は複数の第２凸部を有し、前記第１凸部および前記第２凸部はそれぞれ前記センサプレートの回転方向に並ぶ内燃機関によって達成できる。また、前記回転角センサが設けられる前記センサプレートの周方向に所定角度ずれた位置とは、前記燃焼圧がピークとなる前記クランクシャフトの回転角に対して９０°、または９０°から±５°の範囲内でもよい。また、前記複数の第２凸部は、前記センサプレートに接触することなく、前記センサプレートの回転方向に沿って並び、前記センサプレートに向けて突出してもよい。
The purpose of the above is to detect the passage of a sensor plate that rotates integrally with the crankshaft of an internal combustion engine and has a plurality of first convex portions on the outer peripheral surface, and the first convex portion based on the magnetic flux, thereby detecting the passage of the first convex portion. A rotation angle sensor for detecting the rotation angle of the engine and a magnetic flux concentration portion provided in the rotation angle sensor and located between the rotation angle sensor and the sensor plate are provided, and the crankshaft and the piston are connected to each other. The rotation angle sensor is provided at a position deviated by a predetermined angle in the circumferential direction of the sensor plate with respect to the rotation angle of the crankshaft at which the combustion pressure of the piston closest to the sensor plate peaks. The concentrated portion has a plurality of second convex portions, and the first convex portion and the second convex portion can be achieved by an internal combustion engine arranged in the rotation direction of the sensor plate, respectively. Further, the position deviated by a predetermined angle in the circumferential direction of the sensor plate on which the rotation angle sensor is provided is 90 °, or 90 ° to ± 5 ° with respect to the rotation angle of the crankshaft at which the combustion pressure peaks. It may be within the range of. Further, the plurality of second convex portions may be aligned along the rotation direction of the sensor plate and project toward the sensor plate without contacting the sensor plate.
