The autometer 2 1/16 tachometer is 52mm size. It has black and white color. It can be used on vehicle, boat , marine or other. The engine speed does not correspond to the autometer speed one by one, but generally the faster the engine speed is, the faster the auto speed is. Because there is also a gearbox in the middle, it depends on the gear ratio of the gearbox. For example, when the engine speed is the same, the speed will be different with different gears. It can only be said that if the speed of the car is faster , the engine speed must be faster, but if the engine speed is faster , the car speed may not be faster. For example, when you are in a low gear and step on the accelerator , the speed will not rise, so the speed has no direct relationship with the engine speed.

In terms of engine workmanship, the speed of the engine is related to the amount of work done by the engine in unit time . Therefore , when we talk about the power of this engine autometer , we usually take the corresponding speed with us . It can also be seen from the autometer 2 1/16 tachometer that it can display the idle speed , and the red line indicates the maximum speed of the engine. The higher the speed , the faster the piston moves, and the higher the requirements for the engine. Therefore , the performance of this engine can also be seen from the highest speed on the instrument . Generally, when the car starts at 1500 rpm, it is necessary to shift from first gear to second gear , and then the upshift is usually more than 2000 rpm. In normal driving, the speed at any gear should not be lower than 2000 or higher than 4000 rpm . If the speed exceeds this range, we need to downshift and upshift in time. Because ordinary engines can give full play to their advantages at 2000 to 4000 revolutions. If the speed is too low, the fuel will not burn fully , which will lead to carbon deposition . We must all know the harm of carbon deposition . If the speed is too high , the wear of the cylinder will increase, which will damage the engine for a long time.
