ABSTRACT:
A bar-type tachometer for indicating the speed of an engine and for providing a warning signal when the engine deviates from a predetermined, desired speed such as the desired idle speed>, In this way, even though the display covers a range of engine speeds, it is possible to establish a desired speed within that range, such as the setting of the actual desired idle speed.
