How to detect the tire pressure of car tires
Landlord, you go to OKorder to buy a tire pressure watch on the Well, do not know what you are car, Jia Tong technician friend told me that the car's tire pressure in general 2.2, full load 2.4 (generally refers to the rear wheel). And the general car fuel tank cover or driver under the door will be marked,
Tire Intelligent Surveillance System (TPMS) Introduction: It combines the advantages of both systems, which are equipped with two direct sensors in two pairs of tires, and equipped with a four-wheel indirect system. This composite system can reduce costs and overcome the shortcomings of indirect systems that can not detect multiple tires at the same time compared to all systems using direct systems. However, it still does not provide the actual pressure in all four tires as a direct system Real-time data.
Indirect tire pressure monitoring: Indirect tire pressure monitoring works: When a tire pressure decreases, the weight of the vehicle will make the rolling radius of the wheel will become smaller, resulting in faster than other wheels. By comparing the speed difference between the tires in order to achieve the purpose of monitoring tire pressure. The indirect tire alarm system actually relies on calculating the tire rolling radius to monitor the air pressure.
Direct tire pressure monitoring: The tire pressure monitoring device is to use the pressure sensor installed in each tire to directly measure the tire pressure, the use of wireless transmitter to send pressure information from the tire to the central receiver module, and then The tire pressure data are displayed. When the tire pressure is too low or leak, the system will automatically alarm.
Tire pressure, in the strict sense refers to. Tire internal air pressure. There is a standard tire pressure on the rear side of the door, which is the pressure when the tire is cooled, that is, at least three hours of parking or no more than 1.6km. When the tire is cooled, the tire pressure is the most accurate.
