Is it common for car doors to get paint chipped when opened?

Is it common for car doors to get paint chipped when opened. Precautions when opening doors: Before opening the car door, first observe the left and right rearview mirrors to confirm whether there are vehicles approaching from behind. For rear passengers, it is also necessary to remind the driver to help check the rear situation and only open the door to get off after ensuring safety. Park in a safe place, close to the right side of the road, ensuring no vehicles can come from the right side. Cyclists and pedestrians passing by parked vehicles, especially those that have just stopped, should maintain a lateral distance from the vehicle to guard against sudden door openings. Car paint maintenance: Rinse promptly after rain. Rain stains on the car body will gradually shrink, increasing the concentration of acidic substances in the rainwater. If not rinsed off with clean water promptly, the stains will damage the paint over time. For some special, extremely corrosive marks, remove them promptly. Special cleaning agents must be used for this purpose; avoid using blades to scrape or gasoline to remove them to prevent damage to the paint. Before, during, and after vehicle use, promptly remove dust from the car body to minimize the adsorption of dust by static electricity on the body.

Can Domestic Cars Run 300,000 Kilometers?

With the current mature technology, domestic cars can run 300,000 kilometers as long as they are maintained in a timely manner. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Below is the relevant introduction to car maintenance: 1. Exterior inspection: Before driving, check the doors, engine hood, trunk, and glass condition, inspect the car body for damage, whether the body is tilted, and if there is any oil or water leakage. 2. Engine and various fluids: Check the fixation of engine components, inspect the engine's joint surfaces for oil or water leakage. Check and adjust the tightness of the belt, inspect the fixation of various pipelines and wires. Check and replenish engine oil, coolant, and electrolyte. 3. Tires: Check the tire wear and clean the trunk. When approaching the tire wear mark, replace the tire. Inspect the tires for bulges, abnormal wear, aging cracks, or hard damage. 4. Cleaning and lubrication: Clean the oil stains on the engine hood, door, and trunk hinge mechanisms, and lubricate them. The general service life of antifreeze is 2 years, and it should be replaced during maintenance, thoroughly cleaning the cooling system. Due to the hygroscopicity of the braking system, brake fluid should be replaced every two years.

What Causes a China V Diesel Vehicle to Emit Black Smoke?

China V electronically controlled diesel vehicles emitting black smoke may be caused by incomplete combustion. Common reasons could be a faulty exhaust sensor or poor fuel injector atomization. Black smoke is also referred to as carbon smoke. The primary causes of black smoke emissions from diesel engines are overly rich air-fuel mixture, poor mixture formation, or incomplete combustion. It is recommended to have it checked at a 4S shop. Below is an introduction to diesel vehicles: 1. Definition: Diesel locomotives, also known as internal combustion locomotives, refer to railway locomotives that use diesel engines as the power source and drive the wheels through transmission devices. Internal combustion engines are stable, less prone to failures, fast in speed, quick to start, with strong pulling power, high efficiency, and a powerful sound. The working cycle of a diesel engine shares many similarities with that of a gasoline engine, but the ignition method differs. The air-fuel mixture in a diesel engine cylinder is ignited by compression rather than by spark. 2. Working Principle: The working principle of a diesel engine involves generating kinetic energy by burning diesel in the cylinder, which drives the crank-connecting rod mechanism attached to the piston, performing reciprocating circular motion around the crankshaft to output power. A four-stroke diesel engine consists of four strokes: intake, compression, power, and exhaust.

What is the speed limit on the Hangrui Expressway?

Hangrui Expressway speed limit: The minimum speed limit is 60 km/h, and the maximum is 120 km/h, but the speed limit may vary depending on the section of the expressway. When driving on the expressway, pay attention to traffic signs and do not exceed the speed indicated by the signs. In case of snow, rain, fog, wet or icy roads, or poor visibility, reduce your speed to a safe level below the limit and maintain a necessary safe distance. Do not drive recklessly at high speeds. For the three lanes on the expressway, the speed limits from the left are generally as follows: 1. The maximum speed for small passenger vehicles should not exceed 120 km/h, while other motor vehicles should not exceed 100 km/h. The minimum speed should not be lower than 60 km/h. 2. If there are two lanes in the same direction, the minimum speed for the left lane is 100 km/h; if there are three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 km/h. The minimum speed for the middle lane is 90 km/h. If your speed is above 60 km/h but below 90 km/h, you should drive in the rightmost lane. 3. If the speed limit indicated by road signs differs from the lane speed regulations mentioned above, follow the speed limit indicated by the road signs.

Can I drive my car if the insurance has just expired?

If your car insurance has just expired, the vehicle is not allowed to be driven on the road. You can renew the insurance within 3 months. Once the insurance lapses, if caught by traffic police, you will be fined twice the amount of the compulsory traffic insurance. The compulsory traffic insurance (CTI) can be delayed for payment within 3 months, and the original insurance company can still accept renewal. However, vehicles without CTI are not allowed on the road. Below is relevant information about car insurance: 1. Consequences of not renewing: If car insurance expires and is not renewed, the vehicle will be in an uninsured state, without coverage. Moreover, CTI is a mandatory insurance required by the state, and once discovered, you may face penalties. Additionally, if you renew after the insurance has lapsed, you will need to have the vehicle inspected again, adding to the renewal procedures. 2. Timely renewal: CTI usually needs to be renewed within 90 days before expiration. If discovered by authorities to have lapsed, you will be fined twice the CTI premium. Car owners must pay attention to the validity period of their car insurance to avoid being uninsured. Whether you renew early or late, it's better to do so than to let it lapse. 3. Renewal time: The choice of renewal time varies for each individual. Regardless of whether you choose early or late, it's best not to exceed 24 hours past the insurance expiration date, as it will be considered lapsed. Generally, it is recommended to renew at least 1 month in advance to ensure smooth processing of the renewal procedures.
