Can Run-Flat Tires Still Run Without Air?

Run-flat tires can still run without air. Even if the tire loses all air pressure, it can continue to drive at a speed of 80 kilometers per hour without the need for immediate tire replacement. The differences between run-flat tires and traditional tires include run-flat characteristics, reinforced sidewalls, additional valve stem strips, and high-heat-resistant synthetic rubber materials. The tire pressure monitoring system included in run-flat tires monitors the air pressure of each tire by continuously comparing the rotation speeds of individual tires. When the vehicle speed exceeds 15 kilometers per hour or the tire pressure drops by more than 30%, if the rotation speed of a tire changes irregularly, the system will alert the driver through warning lights and audible signals.

Is a License Plate Lottery Required to Buy a Car in Hangzhou?

Yes. The method for the license plate lottery involves first registering to join the queue, then participating in a unified lottery draw. There is no fee for the lottery. The computer randomly generates 10 numbers, from which the participant selects one. The car license plate lottery is a measure to control vehicle purchases by limiting the number of license plates issued. Below is an introduction to the lottery system: 1. Introduction One: The lottery is similar to a draw—only those who win are eligible to purchase a car. Additionally, the winning rate is adjusted based on the cumulative number of times an individual has participated in the lottery without winning. For those who have participated in the lottery up to 24 times (inclusive) without winning, the winning rate is set at the base rate for that period. 2. Introduction Two: For those who have participated in the lottery 25 to 36 times without winning, the winning rate automatically increases to twice the base rate for that period. For those who have participated 37 to 48 times without winning, the rate increases to three times the base rate, and so on.

Can a Car Specified for 95 Octane Use 92 Octane Gasoline?

Cars specified for 95 octane gasoline should not use 92 octane. Different octane ratings indicate varying levels of octane numbers, with higher octane ratings representing higher octane numbers and better stability. It is highly recommended to use the correct octane rating for your vehicle, as using the wrong one can lead to engine knocking, which may cause damage to the engine. The difference between 95 and 92 octane gasoline lies in their composition: 95 octane gasoline contains 95% isooctane and 5% n-heptane, while 92 octane gasoline contains 92% isooctane and 8% n-heptane. The octane rating does not reflect the quality of the gasoline itself.

Is it necessary to clean the car air conditioner?

It is necessary to clean the car air conditioner. Generally, the car air conditioner should be cleaned once a year. If the driving environment is harsh, this interval should be shortened. When the car air conditioner is turned on for cooling or heating, it operates by repeatedly circulating the air inside the car. Components of the car's interior air circulation system, such as the evaporator, ventilation ducts, and blower, work in dark and humid conditions for long periods, accumulating dirt and breeding large amounts of harmful microorganisms like pathogenic bacteria, mites, and mold. Different types of air conditioning systems have different layouts. Currently, most cars use an integrated heating and cooling air conditioning system, where the evaporator, heater radiator, centrifugal blower, and control mechanism are assembled together, forming the air conditioning unit.

Why Do Car Brakes Make Noise?

Car brakes make noise due to the following reasons: 1. Presence of metal particles in the brake pads; 2. Excessive wear of the brake pads; 3. Excessive wear of the brake discs; 4. Installation issues. Solutions for noisy car brakes include: 1. Replacing with better-quality brake pads; 2. Reinstalling the brake pads. Wear on the brake discs can create deep grooves around the disc, and friction between the brake pads and the edges of these grooves can cause noise. If the grooves are not too deep, the issue can be resolved by grinding the edges of the brake pads to avoid contact with the groove edges. If the grooves are already very deep, it is recommended to replace the brake discs. Generally, it is advised to replace the brake discs once for every two brake pad replacements.

What to Do When the Car Lock Freezes and Won't Lock?

Solutions for a frozen car lock that won't lock: 1. Use warm water to melt the ice on the door. It's important to use warm water, not hot water, as hot water can damage the car's paint. 2. Use a hairdryer to blow hot air directly at the lock cylinder. Once the lock cylinder is heated, it should open. 3. Heat the key's teeth with a lighter or match, then insert it into the lock cylinder. Repeat this process several times to melt the frozen lock. Be careful not to overheat the key, especially if it contains an anti-theft chip. 4. If the door is frozen while you're inside the car, turn on the car's air conditioning and drive to a warm indoor location to thaw the lock.
