tachometer for small engine

• 2022-06-13

If the shift speed is too high, it may be that the transmission is in motion or manual mode, or the engine power is insufficient; The shift speed is too low, which may be that the transmission is in economic mode, etc.

The small engine speed and working status can be known through the tachometer. According to this situation, it can be judged whether the engine is within the safe operation area and whether it is suitable to change gears; It depends on the position of the speed of the instrument panel. Generally, it works through the magnetic principle, so the speed value can be known through the pulse signal.

The small engine tachometer can display the working state of the engine, can be used as a reference for shifting gears, can also allow us to judge whether the car is speeding, and can also enable us to drive better and save more fuel. When looking, we just need to see where the pointer of the tachometer is.

Our small engine tachometer only displays our current engine speed, so that we can observe the current engine speed at any time and keep it within a reasonable speed while driving. Since we seldom observe our engine tachometer and our engine tachometer in our daily use, Rolls Royce boldly changed the engine tachometer into a "power reserve table" to show how much power the driver can control our car? A few automatic transmission and hybrid models do not have engine speedometers, but directly give up and replace speedometers. For example, 15 BYD F0 low configuration models do not have speedometers, and the previous generation Camry hybrid operating mode table, such as ordinary, economic and sports modes.

At present, there are basically only two types of automobile small engine tachometers. One is a mechanical tachometer, and the other is a liquid crystal tachometer. These two types of tachometers are only a form and a manufacturing type. Their specific functions are the same. They both visually observe the digital pulse signal transmitted by the engine through the sensor, and then express it through the tachometer, so as to better provide driving assistance for the driver. For example, when we overtake, we have reached 100km / h, and we don't know whether we can successfully overtake. At this time, we look at our Rolls Royce power reserve table, which may also show that 50% of the power is at your disposal. At this time, we are very confident to step on the accelerator and gallop all the way.
