rpm tachometer for small engines
For the small engines, there is RPM tachometer. In the instrument cluster, we can see that RPM occupies a large area, which is basically not smaller than the area occupied by the vehicle speed. Then , do you know what does this RPM mean? Being able to occupy such a large position proves that it plays a great role, and this RPM actually represents the engine speed. Theoretically, the higher the speed, the stronger the power, but it is not completely correct.
The higher the rpm value, the greater the fuel consumption, the greater the demand for air, and the stronger the power. Therefore, the throttle is directly linked to the rpm value. For manual vehicles, RPM is also an important standard for shifting, which is more accurate than the speed judgment shift standard learned by the driving school. When the rpm is too low, more power can be obtained by downshifting, so that the engine will not be adversely affected by too high RPM (especially in the red area).
The international standard unit of speed is R / S (R / s) or R / min (R / min), while our common rpm is R / min, which is mainly adopted by Japan and Europe, and China adopts the international standard. However, the tachometer units of different models are different. Generally, there are two unit forms" × 100 RPM "and" × 1000rpm ". The actual speed is the current speed obtained by multiplying the number pointed by the pointer and the unit.
The most suitable speed of the engine is 2500-3500r / min, which is the most economical and the working condition is the best, so try to control the speed in this range when driving. Try not to let the engine work below 2000r / min. too low speed will lead to excessive load, damage to the engine and easy to form carbon deposition. Try not to work above 4000R / min. at this time, the fuel combustion is insufficient and the fuel consumption will increase. If you drive in fifth gear, the speed will generally reach 150km / h, which is also a dangerous speed. So we need to choose suitable rpm tachometer for small engines, it is enough safe.You can choose our company , we have different types of RPM tachometers , welcome to send your requests to us!
