Specification:
Although the speed is only a parameter of the engine, as in the
above scenario, the tachometer can transmit a lot of important
information.
The invention of the tachometer to indicate the running state of
the engine was earlier than that of the automobile. It was first
used to detect the rotating speed of the rotating equipment, ensure
that it operates in a safe speed range, and prevent equipment
damage. In the automotive field, it was first used in racing. It is
difficult for a racing driver to judge whether the engine has
reached the maximum speed through sound, but the last trace of
engine performance must be squeezed. Therefore, the introduction of
the tachometer can give the driver an intuitive indication.
