How to Distinguish Run-Flat Tires?

Distinguishing run-flat tires can be done by: 1. Checking the sidewall of the tire for special symbols following the specifications, which are absent in regular tires; 2. Placing the tire flat on the ground and standing on it—run-flat tires have hard sidewalls, while regular tires feel soft when pressed by hand. Run-flat tires are primarily designed to prevent loss of vehicle control in the event of sudden tire pressure loss. They consist of the outer tire, standard inner tube, spare inner tube, steel rim, gas generator, pressure sensor, and control unit. Characteristics of run-flat tires include: 1. They possess support and toughness, allowing the rim and tire to combine and support the vehicle safely during sudden air loss or a blowout; 2. After a blowout, run-flat tires do not immediately lose all air, enabling the driver to continue driving for a certain distance with reduced pressure; 3. The reinforced sidewalls of run-flat tires enhance durability and usability.

What is the difference between Audi's on-demand four-wheel drive and full-time four-wheel drive?

Audi's on-demand four-wheel drive and full-time four-wheel drive differ in the following aspects: 1. Different concepts: Audi's on-demand four-wheel drive means the four-wheel drive system is activated when appropriate, otherwise, it operates as a two-wheel drive system; full-time four-wheel drive is always in a four-wheel drive state. 2. Different applicable conditions: Audi's on-demand four-wheel drive vehicles are convenient to operate and widely used in urban SUV models; full-time four-wheel drive is applied in off-road desert conditions. Audi's sedan models include the A6L, A4, A3, A7, and A8L. Taking the 2021 Audi A6L as an example, it is a mid-to-large-sized car with body dimensions of 5038mm in length, 1886mm in width, 1475mm in height, a wheelbase of 3024mm, a minimum ground clearance of 117mm, and a body weight of 1800kg.

Where is the car oxygen sensor installed?

Location of the car oxygen sensor: one is located behind the exhaust manifold, and the other is behind the three-way catalytic converter. The oxygen sensor behind the exhaust manifold is called the front oxygen sensor, while the one behind the three-way catalytic converter is called the rear oxygen sensor. The oxygen sensor can detect the oxygen content in the exhaust and then feed the data back to the ECU, which can adjust the air-fuel ratio based on this data. The faster the voltage frequency of the oxygen sensor changes, the better the sensor is. If the voltage is 0 millivolts or 1 millivolt or even does not change, it indicates that the oxygen sensor is severely aged and needs to be replaced in time. Under normal circumstances, the signal of the front oxygen sensor is higher than that of the rear oxygen sensor.
