tiny tach diesel tachometer

• 2022-06-22

Our company tachometer can be used on both gasoline vehicle, diesel vehicle . At present, the vast majority of passenger cars on the market are gasoline versions, and a small number of models are both gasoline and diesel versions . The red line speed of the tachometer of gasoline vehicles is generally above 6000RPM , while the red line speed of the tachometer of diesel vehicles is generally about 4000RPM .

The speed of a diesel engine is usually 50-150 rpm. If the engine is too low, it is easy to shake. If it is too high, the fuel consumption is high. As long as it does not shake, the design engineers hope to keep it as low as possible in order to save fuel. Cold start, low water temperature will cause the idle speed to automatically increase by 50-150 rpm.

Diesel engines also have different requirements for engine oil from gasoline, requiring special engine oil. The oil change time should not exceed 6000 km. It is also necessary to strengthen the inspection and maintenance of air filter, oil filter and diesel filter.

In Hall's case, a magnet is equally added to the rotating body, and the sensor is fixed directly to the magnet. During rotation, the sensor and the magnet coincide and are induced once, and the output pulse jumps. The faster the speed is, the higher the frequency output is. The frequency of the output level is proportional to the speed. The speed is measured when the frequency is measured, and the frequency can also be converted into a voltage or current signal.

Diesel engine is just a big category of engines, with various models. According to different uses, its technical parameters are also different, such as vehicle, marine, engineering machinery, generator, agricultural machinery and so on. There are also heavy-duty and light-duty vehicle engines to carry goods and passengers. The technical parameters of engines for different purposes are different, such as the driving capacity and road capacity of the truck after loading, and the speed of the trolley, which makes the speed corresponding to the rated power of the engine of various models different, even for the trolley, the engines of different models and manufacturers are different . Our tachometer suitable for the tiny tach diesel. The maximum power is never the maximum speed. Generally, it is 2000-3000 rpm, and the high-speed engine is even higher.
