Two kilometers on the car dashboard are displayed, one kilometer is displayed as the total kilometer data of the car's cumulative travel, and when the total number of kilometers reaches 50,000 kilometers, it is generally necessary to replace the car tires, and the tire replacement of the operating vehicle is not according to the total number of kilometers. The other kilometer is shown as the number of kilometers traveled after the car is maintained, and when the number of kilometers reaches 5000 kilometers and 7500 kilometers, the vehicle needs maintenance.
The basic principle of the car odometer: the car odometer is a kind of digital explicit in-car dashboard, which rotates the tooth shaft of the electronic counter drum wheel and the vortex rod on the speedometer drive shaft to make the electronic counter drum wheel rotate. It is characterized by a full circle of drum rotations at the upper stage. The next stage drum rotates 1/10 turn.
Like the speedometer, the current odometer also has an electronic odometer, which obtains the mileage data signal from the speed sensor. The mileage accumulated by the electronic odometer is stored in non-volatile memory, and the data information in the non-electric form of the lower state can also be stored.
The vehicle's speedometer has two odometers on top, the upper odometer is the total odometer, and the lower odometer can be zeroed.
Vehicle kilometers can be seen on the odometer, usually with ODO to indicate, after the label contains enterprise km, that is, to indicate the total mileage of the vehicle today, its effect can allow the driver to understand the distance between the driving, can be converted out of the fuel cost, the side reflects whether the vehicle is fuel-efficient.
Car speedometer is a digital instrument, soft shaft rotation in the worm gear worm will be transmitted to the roller counter in the middle of the speedometer, the speed of the wheel represented by the mileage accumulated, speed and mileage are driven by the same soft shaft from the rotation action, so the speedometer will have a pointer just, and the odometer is accumulated according to the roller counter.
Extension Materials:
The vehicle odometer is described in detail as follows:
The parking situation indicates fuel consumption per hour, which is now indicated as 0.6 liters per hour, and when the car is driving, it is indicated here: 4.5L/100KM, which means 4.5 liters of fuel consumption per 100 kilometers. It shows that according to the previous driving situation, the number of kilometers that the remaining oil can be stored alone can be driven again, and it can be noted that the fuel needs to be given according to this data information.
