RPM CALCULATING APPARATUS FOR CONTROLLING ENGINE CAPABLE OF EXPANDING HIGH RPM REGION WITHOUT CHANGING CALCULATION PERIOD

摘要

Without changing the operation cycle to obtain a low rotational speed without reducing the operational capability of the zone, the number of revolutions the engine for controlling the zoom operation can be high speed region by the easy operation processing device.; And a rotation sensor (3) for generating a detection pulse P in accordance with the rotation speed, and calculating the number of revolutions according to the detection pulse, provided with a microcomputer 20 for controlling the engine, the detection pulse Pd is included in the plurality of the pulse sequence microcomputer is, selecting a pulse series of a plurality of pulse series in accordance with the operation region of the engine, and calculates the number of revolutions in relation to the engine along with the detection time and the selected pulse sequence.
