Our company sell the small engine hour meter tachometer. Please see the below picture.

Four common uses of automobile engine tachometer:

1. The tachometer can be used to determine whether the automobile really starts.
2. The tachometer allows you to determine when to shift gears.
3. There is a red area on the tachometer. For the engine , the defect of the red area is the limit speed of the engine . If it is maintained for a long time in high load movement , the engine will have poor heat dissipation and eventually damage the mechanical parts.
4. It can judge the status of the car through the display on the tachometer when the engine is idling .

The tachometer is caused by the weight of the car's accelerator. Of course , it also has something to do with the gear . If the accelerator is pressed heavily, the higher the speed , the higher the fuel consumption. If the speed is too high and reaches the red line of the tachometer , it indicates that the engine is running too fast and the fuel supply of the fuel delivery pipe has failed to keep up , and the fuel cut-off phenomenon will occur . At this time, the sound of the engine will be short and long .

Generally, when the speed is high and the gear is shifted to a higher gear, the transmission can operate at a higher gear . If you gear up at a low speed and the car needs to accelerate , but the engine can't keep up , it will stall . If the speed is at the normal position and the car is forced to reduce to a higher gear , the car will decelerate, but the engine is still at the high gear , and the unusable force will be converted to a high speed , which will suddenly jump from the low speed to the high speed.

First of all, the idle speed should be about 800-1000 RPM after the water temperature is normal; The second is the reference of shift timing. Generally, it is controlled at about 2000 rpm to shift in time. If the speed is too high, it will waste oil. If the speed is too low, the car will lack power.

The hour meter of this tachometer can be adjusted accumulatively.
