tachometer with shift light, and what is tachometer

• 2023-05-19

The tachometer is the engine speed, commonly known as the throttle size indicator . The speedometer is the number of kilometers per hour, commonly known as the vehicle speed . Our company can provide a combination of tachometer and speedometer , and it with shift light . The difference between a tachometer and an hour meter is as follows:

1.The content is different: the speedometer reflects how much distance the vehicle has traveled per hour, while the tachometer reflects how many revolutions the engine has made per minute; 2. Different directions indicated: the speedometer refers to a vehicle's driving speed generally ranging from 0-300KM/u002Fh . The tachometer refers to the engine speed , which is generally 0-8000r/u002Fmin.

There are two important meters in a car, one is the car tachometer, and the other is the car driving speed meter. These two types of meters have different functions, but they are both important instruments that provide the driver with the current driving conditions. During the driving process , the driver can decide what to do next based on the current speed of the engine. It can minimize misoperation to the greatest extent . In this way , it can be targeted . This is particularly important for manual transmission vehicles . The tachometer unit is 1/min × 1000, which means displaying how many thousand revolutions per minute the engine is rotating.

The tachometer can visually display the engine speed under various operating conditions. Drivers can always understand the operation of the engine , grasp the timing of gear changes, cooperate with the transmission gear and throttle position , and maintain the optimal working state, which is conducive to reducing fuel consumption and extending engine life. The tachometer is generally installed on the dashboard and symmetrically placed together with the speed odometer. The tachometer operates on the principle of magnetism , receiving pulse signals generated by the interruption of primary current in the ignition coil and converting them into displayed speed values. The faster the engine speed, the more pulses generated by the ignition coil, and the higher the speed value displayed on the meter. Some people also refer to it as an odometer, speedometer, etc. Through instruments, drivers can understand the current driving status of the car and decide to maintain or change the current driving status based on this data. Minimize misoperation as much as possible.
