how to check rpm without tachometer

• 2022-04-08

The instrument of the motorcycle can really intuitively display the driving data, but it is only an auxiliary system. The old driver can feel the changes of the vehicle by feeling, but the novice motorcycle doesn't have such ability. So what good method can help the novice feel the speed of the engine?

In fact, novices can judge the engine speed by observing the data of motorcycle kilometer meter, because the values of tachometer and kilometer meter are basically the same on flat road, that is to say, when the speed is 50km / h, the engine speed is basically about 5000 rpm.

Secondly, the engine speed can also be judged by the sound of the engine, but this needs to be observed deliberately, because each car will have different sensory changes, but the mystery can be found by observing it several times. Generally, a loud engine sound indicates that the engine speed is high, on the contrary , the speed is low.

If you think it is necessary to intuitively reflect the engine speed, you can add a rpm tachometer. In fact, this operation is relatively simple and does not cost much money, because the internal space of the curved beam vehicle instrument is still relatively large. Even if it cannot be installed inside, you can add a rpm tachometer outside . As long as it is reasonably designed, it will not affect the beauty of the vehicle. In fact, its technical content is also very low, which can be done through an induction line . Then our company provides all kinds of tachometers. Welcome to buy them .

If you are driving a small car , a simple way is to tell you : when you hear the sound of the engine while driving and the speed is not very fast, it means that the engine has more than 2000 revolutions . You can also listen to the sound. The louder the sound, the higher the speed! If you want to increase the speed! Just step on the accelerator! One principle: start with one gear; When the car moves , change to second gear ; If the speed exceeds 20km / h, shift to third gear; If it exceeds 30 km / h , shift to fourth gear; If it exceeds 40 km / h , shift to fifth gear . The opposite is true.
