转速表, 转速计
a measuring instrument displaying the revolutions per minute of an engine
A tachometer is a device in a vehicle that measures the engine's speed, usually displayed in revolutions per minute (RPM). It shows how fast the engine is turning, helping the driver understand when to shift gears in manual transmissions or to monitor engine performance. By observing the tachometer, drivers can avoid overworking the engine, which can cause damage. The reading is typically shown on the dashboard, near the speedometer, and it helps ensure the engine runs efficiently. It is especially useful in performance cars or vehicles requiring precise engine control.
