The differences between small, medium, and large ratchet wrenches include variations in wrench size and the size of nuts they can tighten or loosen. Below is a detailed introduction to the differences between small, medium, and large ratchet wrenches: Differences in wrench size: 3/8 refers to the side length of the square interface on the socket wrench, which is 3/8 inches in length. 1/4 small ratchet wrench has a square drive size of 6.3MM. 3/8 medium ratchet wrench has a square drive size of 9.5MM. 1/2 large ratchet wrench has a square drive size of 12.5MM and provides greater torque. Differences in nut size they can handle: Small ratchet wrenches are particularly suitable for tightening or loosening nuts with sockets under 14MM. Medium ratchet wrenches are suitable for use with sockets up to 24MM. Large ratchet wrenches are suitable for working with sockets up to 32MM.

Where is the tire pressure sensor located on the Baojun 510?

The tire pressure sensor on the Baojun 510 is located in the instrument cluster's onboard computer. The tire pressure monitoring system automatically monitors the tire pressure in real-time during vehicle operation and alerts the driver to tire leaks or low pressure to ensure driving safety. There are three commonly used types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via wireless transmitters, then displays the data for each tire. The system automatically alerts the driver when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the differences in rotational speed between the tires, the system monitors the tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of the two aforementioned systems. It equips direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.
