1. The national road traffic safety authority (nhtsa) of the united states of america, which has published reports of potential flat tires, has a flat pressure below the standard of 25 per cent, with a threefold increase in the rate of flat tires; 25 per cent above the standard, with a one-fold increase in the rate of flat tires; 2 the reduction of brakes is excessive, with fewer areas of frontal and ground contact and less friction, increases brake distances; 3 the increase in fuel pressure, with more area of surface and ground contact, increases friction and resistance and increases in fuel consumption; 4 the reduction of tyre life pressure is excessive, with excessive wear in the middle of the tyre; and the excessive wear of the tire pressure, with excessive wear on both sides of the face of the tires, leads to premature reporting of tyres。
Is it necessary to install a foetal monitoring system
It is essential to monitor the tire pressure, which is the only component of the vehicle that is exposed to the ground, the driving force and the power of which are derived from the tyre, the safety of all tyres is essential, and the monitoring of the tire can serve to safeguard the optimal condition of the tyre。
For flat tires, the leakage of tyres is difficult to detect, and if the leak continues, it can lead to the tire being worn and the entire tyre being scrapped。
It is therefore necessary to provide for additional tyre pressure monitoring of cars, although for a small number of tires that are thick, the role of tyre pressure monitoring for this type of vehicle is clearly less obvious, given that if the tyre leaks, the driver can easily detect it。
What are the types of fetal pressure monitors? What's the difference
Following the location of the installation of the sensor, it is possible to separate the external internal pressure monitoring and the external pressure monitoring. The difference between the internal/external sensor is that: 1) the internal pressure monitor is installed inside the tyre, replacing the original aerobics, and the external pressure monitor is installed directly on the tyre aerobics. 2) the built-in foetal pressure detector needs to be balanced and the external foetal pressure detector does not. 3) batteries with built-in foetal pressure detectors have a useful life of 3-5 years, compared to 1-2 years for external models. 4) when tyres are replaced, the built-in tyre pressure detector needs to be rematched and the external formula needs to be adjusted accordingly。
5) the built-in formula can inflate the tyre directly, while the external formula needs to be removed before it is inflated。
In contrast, the built-in formula is more cumbersome in terms of installation and maintenance, requiring the removal of tyres but with a longer useful life. The external installation and maintenance is simpler, and it can be installed without the need to remove tyres; however, it has a short useful life and each inflate requires the removal of the sensor。
2. What are the differences between indirect foetal pressure monitoring (wsb) and direct foetal pressure monitoring (psb) as measured? What's better
Direct psb foetal pressure monitoring is the direct monitoring of tyres by the installation of a sensor that accurately shows the barometer values of the four tyres, which point immediately to the failure of the tyre in the event of an anomaly. Direct psb tyre pressure monitoring is not influenced by the environment such as vibration, temperature, speed, etc., and the actual instant pressure of each tyre can be measured at any time。
Wsb indirect tyre pressure monitoring is monitored through the abs system to determine which tyre has broken down and cannot be reported to the police in the event of an anomaly in the same axis or more. Furthermore, wsb indirect foetal pressure monitoring is not satisfactory in road conditions and can be misreported in case of vehicular bumps, and lapses after speeds exceeding 100 km/h per hour. So, the psb direct fetal pressure monitoring is better。
These rumours about tire pressure are not credible
In fact, the replacement of tyres is not determined by the itinerary but by the degree of wear or tear of the tyres. If the tire is worn to a certain extent, which affects the safety of the vehicle, it must be replaced, not so much as the mileage。
Tyres, however, have a certain shelf life, and tyres that exceed the shelf life should preferably not be used. After the warranty period has passed, internal materials (e. G. Rubber) have aged, and tyres should be replaced in a timely manner, although the tires have not yet been worn to the point of replacement。
2. Need to regulate different fetal pressure according to season
The question of whether this theory is correct was mentioned by netizens that the pressure of tyres should be lower in summer and higher in winter. The pressure of tyres increases when the temperature is high and decreases when the temperature is low, which is a physical change, i. E. The principle of thermal expansion。
However, in the day-to-day use of vehicles, there is no need for man-made increases or lower air pressure based on seasonal variations. This is because changes in fetal pressure are within the safety pressure limit of the tyre, as long as they remain close to the standard pressure given by the manufacturer, which can be unexpected in the summer. Summary
In order to avoid anomalous foetal pressure during the routine use of vehicles, it is a method of indigence examination. However, for those who stick nails in the road, it may be that the leaks are carried out in silence, that failure to pay attention leads to a flat tire and that a tyre is wasted in vain, and it is important to have a tire pressure monitoring system。
The original vehicle is currently equipped with a small number of vehicle models monitored with tire pressure, but the owner can still choose to load itself. Experts suggested that, if conditions permit or are installed to monitor foetal pressure, it would be preferable to choose a well-known brand when purchasing the foetal pressure monitor, which would guarantee after-sale services. When selecting, care should also be taken to select chips of better quality。
