PURPOSE:To aim at simplifying the structure of a device by accumulating the number of angle pulses generated at an angle pulse generating means by a single counting means and transferring the enumeration data every time an ignition signal is generated so as to be accumulated and memorized in a memory means. CONSTITUTION:While the ignition signal of each air cylinder and the reference pulse from an encoder 14 are incorporated into a logic analyzer 18 through a connecting line 15 and a trigger detecting part, the angle pulse from the encoder 14 is incorporated into a pulse counter 16 through a connecting line L10. When the reference pulse from the encoder 14 and the ignition signals are generated, data counted by the pulse counter 16 are read and memorized in the logic analyzer 18. This memory is performed in such a way as to accumulate the enumeration data of the pulse counter 16 continuously until a rotor 12 is rotated up to the fixed number of rotation. This accumulated and memorized data is transferred to a personal computer and the computation of the ignition timing and the like is executed by this personal computer. |
