Zusammenfassung:	The utility model discloses a rotating speed chronometer for an engine, which comprises a chronometer disc, a signal detection part, a frequency pressure converter, a timer, an alarm, and a rectification and voltage stabilization part. The utility model has the main technical proposal that the hose drive of an original chronometer is removed, a frequency signal is led out from a center wire or any one of phase wires of a generator by a connecting wire, and the frequency signal is delivered to the signal detection part to shape; the frequency signal is converted into a voltage signal by the frequency pressure converter, and the voltage signal drives a luminotron of the chronometer disc to display rotating speed by a driver. The utility model has the advantage of stable operation without external interference.
