Indirect tire pressure monitoring is useful as it determines which tire has abnormal pressure by comparing the rotational speeds of the tires. Indirect tire pressure monitoring technology can now accurately identify the specific tire with pressure loss. Tire pressure refers to the air pressure inside the tire, and its level plays a significant role in the performance and power of the vehicle. The working principle of indirect tire pressure monitoring: when the pressure of a tire decreases, the weight of the vehicle causes the rolling radius of that wheel to become smaller, resulting in a faster rotational speed compared to other wheels. By comparing the differences in rotational speeds between tires, the purpose of monitoring tire pressure is achieved. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor air pressure.

How many kilograms is one liter of 95 gasoline equal to?

Equals 1.5 kilograms. Here is the relevant information: 1. Conversion method: Convert based on the density of gasoline. The density of 95 gasoline is 0.737g/ml, so one liter of 95 gasoline is approximately equal to 0.75 kilograms, which is 1.5 kilograms. The density of different grades of gasoline varies. For example, the density of 93 gasoline is 0.725g per milliliter, and the density of 97 gasoline is 0.737g per milliliter. 2. Notes: It is best to refuel in the morning or evening because the temperature is high at noon, and thermal expansion and contraction will cause the volume of gasoline to expand, resulting in less fuel being added. Do not use mobile phones while refueling, as using a mobile phone may generate sparks, which can easily cause a fire when in contact with the dense gas at the gas station.

What are the new regulations for motorcycles in 2021?

According to the new regulations issued by the Ministry of Public Security, the 2021 motorcycle regulations are as follows: 1. Cross-region convenience, one-certificate examination, and nationwide examination: In 2021, motorcycles will implement a nationwide 'cross-region convenience, one-certificate examination, and nationwide examination' policy for driver's licenses. Applicants can apply for a motorcycle driver's license anywhere in the country with their resident ID card, without the need to submit a residence permit or residence registration certificate. This will benefit 300,000 people who take the motorcycle driver's license examination in different regions each year. At the same time, the transfer of motorcycle registration information will be conducted online. Applicants can directly apply for the transfer at the vehicle management office in the destination city without returning to the original location for vehicle inspection or retrieving paper files, reducing face-to-face contact and eliminating the need for round trips between two locations. 2. Enhanced online services: The 'online service' experience will be deepened. Drivers can use the 'Traffic Management 12123' app to query and download records of traffic accidents, changes in permitted driving models, traffic violations, and full-point penalties, making it convenient for them to present and use electronic traffic safety records in their professional and personal lives, such as job applications, thereby promoting a sense of integrity and law-abiding among drivers. 3. One-vehicle-one-invoice system: Starting from July 1, 2021, the 'one-vehicle-one-invoice' system will be officially implemented for electric vehicles. According to the 'Measures for the Use of Motor Vehicle Invoices' jointly formulated and issued by the State Administration of Taxation, the Ministry of Industry and Information Technology, and the Ministry of Public Security, the electric vehicle industry will officially implement the one-vehicle-one-invoice system from July 1, 2021. Electric motorcycles, electric light motorcycles, electric tricycles, and low-speed four-wheeled vehicles included in the motor vehicle management category must complete tax payments and issue invoices. By then, unqualified manufacturers and products without 3C certification will be eliminated from the market. 4. Optimization of motorcycle scrapping period: According to the latest regulations, three-wheeled motorcycles will be scrapped after 10 years of use, while two-wheeled motorcycles and side three-wheeled motorcycles will be scrapped after 11 years.

How to Turn Off the Overhead Air Conditioning in a Bus?

Adjust the small flap at the air outlet to change the direction; move it parallel to the ground to close it. Below is relevant information about vehicle air conditioning: 1. Introduction: Vehicle air conditioning systems consist of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. They regulate cabin temperature and humidity to provide a comfortable environment for passengers. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the refrigerant's temperature and pressure increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy. The liquid refrigerant then flows through the throttle device, where its temperature and pressure decrease before entering the evaporator.

Is it allowed to drive in slippers?

Driving in slippers is not allowed. According to Article 62, Clause 3 of the "Regulations for the Implementation of the Road Traffic Safety Law": while driving, no other actions that hinder safe driving are permitted (depending on the specific action). According to Article 90 of the "Road Traffic Safety Law", a penalty of 2 demerit points and a fine should be imposed. Motor vehicle drivers are not allowed to drive wearing slippers. In the event of an accident, if one of the drivers is wearing slippers, even if the driver is not at fault for the entire accident and the accident responsibility is borne by the other party, the driver will still be penalized by the traffic police for driving in slippers. The dangers of driving in slippers: 1. It can easily lead to tragedy: Driving requires the use of both hands and feet. Driving in slippers, like driving while using a mobile phone, eating, or watching TV, violates the "Traffic Law", so it is hoped that car owners will take this as a warning. In addition, if the foot slips, fails to press firmly, or misses the brake pedal when stepping on the brake, it can easily lead to tragedy. 2. Difficulty in controlling the pressure on the accelerator and brake: Wearing slippers provides poor foot sensation, making it difficult to control the pressure on the accelerator and brake. Experimental data shows that driving in slippers has the highest risk index. It is reported that a brake reaction tester was installed in a car, and flat shoes and slippers were tested 10 times each for brake reaction. The test results showed that the reaction difference between slippers and flat shoes was 0.6 seconds, meaning that slippers are 0.6 seconds slower than flat shoes in reaction time. This 0.6-second difference affects the braking distance by 17 meters.

Why does the screen go black when connecting Apple CarPlay to the car?

There are several main reasons why the screen goes black when connecting Apple CarPlay to the car: 1. The car's computer crashes: Nowadays, cars have many electronic components, especially with the continuous updates and iterations of car connectivity systems. Many car multimedia systems are quite complex, leading to an increase in failures of the car's large screen. You can try turning off the car and restarting both the vehicle and the car's computer to see if the large screen display can be restored. If repeated attempts still don't resolve the issue, schedule a visit to a 4S shop to inspect, refresh, or repair the corresponding module. 2. The line clips become detached: Many connections are made using clip-on plugs. When encountering bumpy roads or due to the original installation quality, the clips may become detached or loose, causing the car's large screen to malfunction. In this case, you can only visit a 4S shop or repair shop to have the large screen removed and the clips reinserted and tightened.
