Title: Magnetostrictive torque detector for internal combustion engine
Inventor: IKEDA SHINJI
IPC: F02D45/00
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To improve torque detecting accuracy of an output shaft of an internal combustion engine while preventing an increase of its cost. SOLUTION: The magnetostrictive torque detector for an internal combustion engine comprises a magnetic sensor 12 and an engine rotational speed sensor 36 for detecting torque maximum value and engine rotational speed maximum value corresponding to each cylinder to correct the torque maximum value larger than a predetermined value of the torque maximum values corresponding to respective cylinders based on the torque maximum values and engine rotational speed maximum values corresponding to the respective cylinders. Thus, even if the magnetizing part of an output shaft with irregular magnetizing characteristics is used, torque detecting accuracy of the detector is not lowered.
