The Design and Experimental Study of Internal COmbustion Engine Speed-Measuring Device

摘要

The engine speed-measuring device is composed of an approach switch, a gear, a signal-processing circuit and indicators. It provides reversing signals, impulse volume and analloging running speed signals of the logic control system and the speed-and-load automatic control system of an internal combustion engine. Made in this paepr are a detailed analysis of the working principles of the circuit, and a description of the paraemters on which the choice of the main components are based. The experimental conditions, data the linder relations between speed and out-put voltage are also given.
