The detector of the rotation speed of the engine and mu00ecnima process to detect the rotation of the motor mu00ecnima valocidade

摘要

To provide a minimum rotation speed detector of engine of low cost and easy to use, which makes it possible to find precisely a minimum rotation speed of the engine.A detector of the minimum rotation speed of engine (10) includes a first oscillator (12a) fixed on a base (11) having a frequency of vibration characteristic of a vibration frequency of an engine (20) operating at a speed of rotation normal minimum.The base (11) of the minimum rotation speed detector (10) is fixed on the engine (20) and the minimum rotation speed detector (10) detects a rotation speed of the engine is minimum (20) in the form of ressonu00e3ncia the first oscillator (12a).
