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.
