Abstract

The invention provides an idling speed detecting device of an engine using the cheap and simply operated device to accurately detect the idling speed of the engine. In the idling speed detecting device (10) of the engine, a first vibrating element (12A) having the fixed vibratory frequency the same with the vibratory frequency of the rotary engine (20) with normal idling speed is fixed on the base (11). The idling speed detecting device (10) fixes the base (11) on the engine (20) and uses the resonance of the first vibrating element (12A) to detect the idling speed of the engine (20).

Description

technical field [0001] The present invention relates to an engine idle speed detection device and an idle speed detection method, and particularly relates to an engine idle speed detection which can easily detect the engine idle speed with cheap and easy-to-operate equipment without using a measuring device such as a tachometer Device and idle speed detection method. Background technique [0002] If the engine of a vehicle or the like does not set the idling rotation speed during warm-up operation within an appropriate range, the starting performance of the engine may be deteriorated or the life of the engine may be affected. Therefore, the rotational speed adjustment mechanism is operated to adjust the concentration of the mixed gas to adjust to an appropriate idle rotational speed. [0003] The idle speed adjustment of a vehicle equipped with a tachometer is performed while checking the engine speed through the tachometer, so that the idle speed can be set to a correct sp...
