A tachometer in a car is a special measuring device that calculates the speed of the crankshaft per unit of time.
A car tachometer is primarily indispensable for a car with a manual transmission so that the driver shifts gears in time and does not exceed the maximum allowable engine speed, which can lead to its breakdown and premature wear. Regardless of the type of tachometer installed in the car, this is an important and necessary device that should be monitored especially by beginners to shift gears on a manual gearbox in time and prevent excessive engine overload. The main function is to facilitate the selection of the correct gear. When the arrow approaches the red zone, it is advised to shift to a higher gear.
