Title:
多気筒内燃機関用回転情報検出装置
Document Type and Number:
Japanese Patent JP4140246
Kind Code:
B2
Abstract:
A signal generator for an internal combustion engine for obtaining precise information on a rotational direction of the engine when the engine runs at extremely low speed, comprising: a rotor having a first series of reluctor corresponding to a cylinder of the engine, and a second series of reluctor having a predetermined phase relationship relative to the first series of reluctor; and a first sensor and a second sensor that detect the first series of reluctor and the second series of reluctor, respectively of the rotor to generate pulses, wherein a positional relationship between the first and the second series of reluctors, and a positional relationship between the first and the second sensors are set so that a difference occurs in a phase relationship between an output pulse of the first sensor and that of the second sensor in forward rotation and in reverse rotation of the engine.
