What is the purpose of purchasing car insurance?

Car insurance is a type of property insurance, also known as motor vehicle insurance. It refers to a commercial insurance that compensates for personal injury, death, or property damage caused by natural disasters or accidents involving motor vehicles. Below is an introduction to the roles of various types of car insurance: 1. Compulsory Traffic Insurance: This is a mandatory insurance required by the state, which compensates for the losses of third-party victims within the liability limits in the event of a traffic accident. 2. Third-Party Liability Insurance: Commonly referred to as 'Three-Party Insurance,' it compensates for the direct losses of third parties in accidents involving personal injury, death, or property damage. It serves as the strongest supplement to Compulsory Traffic Insurance in terms of coverage, with optional coverage ranging from hundreds of thousands to millions. 3. Vehicle Damage Insurance: This insurance compensates for the shortcomings of Compulsory Traffic Insurance and Third-Party Liability Insurance, which do not cover damages to the insured's own vehicle. Daily driving inevitably involves minor collisions, and without Vehicle Damage Insurance, the repair costs would have to be borne by the vehicle owner. 4. No-Deductible Insurance: Vehicle Damage Insurance and Third-Party Liability Insurance set different deductible rates based on accident liability. To minimize personal losses, vehicle owners can purchase No-Deductible Insurance as an add-on, transferring their share of the liability back to the insurance company. 5. Theft and Robbery Insurance: Comprehensive Theft and Robbery Insurance covers situations where the insured vehicle is stolen or robbed under non-intentional, non-deliberate, and non-violation circumstances. If the case remains unsolved after reporting and investigation within a certain period, the insurance company compensates for the corresponding losses.

What type of engine oil is used for the Audi Q7?

Audi Q7 originally uses 0W30 - Castrol EDGE engine oil. For later maintenance and oil changes, you can choose Audi-specific engine oil, Mobil 1, or Shell synthetic oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high-temperature conditions. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in an Audi Q7 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler cap on the engine valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick and ensure the engine oil level is within the standard range.

What is the difference between brake lights and tail lights?

The differences between brake lights and tail lights are as follows: 1. Different light colors: The brake light is red; the tail light is white. 2. Different usage times: The brake light turns on when the brake is pressed; the tail light remains on continuously. 3. Different functions: The brake light effectively prevents rear-end collisions, reduces traffic accidents, and alerts following vehicles that the car is slowing down or stopping. Incorrect use or malfunction of the brake light can easily lead to rear-end collisions. The tail light mainly includes amber turn signals that indicate the direction of the car and reverse lights that assist in observation.

Causes and Solutions for High Temperature in Single-Cylinder Diesel Engines

The causes of high temperature in automotive diesel engines include insufficient coolant and loose fan belts. Below are detailed explanations of the causes and corresponding solutions: 1. Insufficient Coolant: If the diesel engine's cooling system lacks coolant, it will affect the engine's heat dissipation, leading to high temperatures. Solution: Regularly check the coolant level in the radiator and expansion tank, and replenish it promptly if the level is low. 2. Loose or Faulty Fan Belt: If the cooling fan malfunctions, the motor and circuit need to be inspected and repaired. Solution: Tighten the fan belt or replace it directly.

How long does it take to charge a 12v maintenance-free battery?

12v maintenance-free battery charging time is approximately 20 hours. Here is the relevant introduction about 12v maintenance-free batteries: 1. Features: Due to structural advantages, maintenance-free batteries consume very little electrolyte and basically do not require distilled water replenishment during their service life. They also feature shock resistance, high temperature resistance, compact size, and low self-discharge. The service life is generally twice that of conventional batteries. 2. Charging method: Maintenance-free batteries can also be recharged, and the charging method is basically the same as that of conventional batteries.

What to Do in an Emergency When the Wiper is Broken?

Here are the methods to deal with a broken wiper: 1. Inspect and handle: Check the wiper's fuse, locate the fuse box to see if it's blown, promptly find a spare fuse, and ensure the replacement matches the correct amperage during installation to avoid short circuits. Then replace it and restart the wiper. 2. Adjust position and handle: Determine if the wiper motor is damaged. If the car's motor is faulty and cannot be fixed, slowly park the car in a safe area and take it to a repair shop. Driving in heavy rain without wipers is not recommended, as it can obstruct the windshield visibility and easily lead to traffic accidents, which is very dangerous.
