Why does the car make a clunking sound when driving?

Can the ornaments from an old car be placed in a new car?

It is better to get a new set. Cars have made life more convenient, but they also inevitably cause some accidents and injuries. Some people who are particular about such things place small ornaments in their cars to ensure safety. However, the most important aspect of car safety still lies in adhering to common sense and rules. Do not focus solely on feng shui and symbolism, and avoid hanging ornaments that may obstruct driving safety. Here are some driving tips: 1. Check the rearview mirror: Always use turn signals and slow down when turning or changing lanes. Before turning, be sure to check the rearview mirror. Left turns mainly require checking the left rearview mirror, right turns mainly require checking the right rearview mirror, and both left and right turns require checking the interior rearview mirror. 2. Do not stare at the front of the car: When driving on a clear road, look straight ahead at about 100 meters, and avoid staring at the immediate front of the car. 3. Depress the clutch: Generally, when slowing down at speeds above 40 km/h, there is no need to depress the clutch first. Depress the clutch when the speed drops to around 20 km/h. 4. Steering: Turn the steering wheel slowly at high speeds and quickly at low speeds.

How to Repair a Sun-Damaged Car Dashboard?

1. Methods for repairing a sun-damaged car dashboard are as follows: 1. Large decoration shops: Large decoration shops can handle it, though it's usually more expensive. A simpler method is to apply a dashboard film. 2. Interior renovation shops: Find a shop that specializes in interior renovation; they can reupholster the dashboard to match the original material and color. 3. Interior modification shops: Look for a shop that does interior modifications to have the dashboard reupholstered with leather for a more premium look. 2. Below is an introduction to the car's central control system: 1. Central locking system: There are many types of central locking systems installed in cars, but their basic components mainly include door lock switches, door lock actuators, and door lock controllers. 2. Switches: Most central locking switches consist of a master switch and sub-switches. The master switch is located on the driver's side door, allowing the driver to lock or unlock all doors. Sub-switches are installed on other doors for individual control. 3. Actuators: Central locking actuators execute the driver's commands to lock or unlock the doors. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. Their structures all involve changing polarity to reverse motion direction for locking or unlocking actions.

How Many Airbags Does the Geely Borui Have?

The Geely Borui is equipped with four airbags. In addition to the commonly known ones in the steering wheel and the front passenger dashboard, there are also curtain airbags on both the left and right sides of the roof. Introduction to Airbags: The airbag system is a passive safety protection system (see vehicle safety performance) that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. Components of Airbags: Mainly composed of airbag sensors, collision airbags, and electronic control devices. The driver-side collision airbag is installed in the steering wheel, while the passenger-side collision airbag is generally mounted on the dashboard. Airbag sensors are installed on the left, right, and center partitions of the driver's compartment; the central airbag sensor and the airbag system are integrated with the electronic control device. The airbag module primarily consists of the airbag, gas generator, and igniter. The electronic control device is used for data collection and processing, diagnosing the reliability of the airbag, ensuring timely ignition signals are issued when preset values are reached, and guaranteeing precise ignition timing to provide sufficient driving current for the gas generator.

Is 32% Concentration AdBlue Compliant for China VI Vehicles?

China VI compliant AdBlue has a 32% concentration. The China VI engine standard specifies the concentration of AdBlue solution at 32.5%. At this concentration, the freezing point of the AdBlue solution is -11°C. In the aftertreatment system, the concentration of the urea solution is one of the critical factors. Concentrations that are too high or too low not only fail to improve NOx conversion efficiency but can also lead to ammonia slip (ammonia leakage due to an excessively high NH3/NOx ratio), resulting in secondary pollution from ammonia gas. Below is an introduction to AdBlue: 1. Origin: AdBlue solution was first used in Europe, where it is called AdBlue. In North America, it is referred to as DEF (Diesel Exhaust Fluid), while in China, it is known as AdBlue solution or "vehicle denitrification agent." However, it is now generally referred to as "AdBlue" in China. 2. Function: AdBlue solution is key to reducing pollutant emissions from diesel vehicles. AdBlue solution is a urea-based chemical reactant, composed of high-purity urea and deionized water, forming a solution with a concentration of 32.5%. The application of AdBlue solution in the SCR system is crucial for engine exhaust emissions to meet China IV and higher emission standards.

What Happens If the Car's Catalytic Converter Is Removed?

The function of a car's catalytic converter is to enhance the purification of exhaust emissions. If removed, it will increase the vehicle's exhaust emissions because without the catalytic converter, the exhaust gases cannot be effectively purified, leading to emissions that exceed standards. Additionally, it will reduce the car's power and increase fuel consumption. Below are the reasons for high fuel consumption: 1. Improper driving habits: Fuel consumption is closely related to the driver's habits, such as prolonged idling without turning off the engine or frequent starts, aggressive acceleration or frequent braking, driving at low gear with high speed or high gear with low speed, etc. These driving habits significantly 'contribute' to increased fuel consumption. 2. Abnormal tire pressure and tire wear: Low tire pressure increases friction between the tires and the ground, raising resistance and thus fuel consumption. Normal tire pressure is around 2.5bar, which can be slightly reduced by 0.1bar in summer. Of course, tire pressure should not be too high either; it's best to inflate according to the vehicle's standard values. Moreover, severely worn tires often cause slipping, which also increases fuel consumption. 3. Fuel quality and carbon buildup: Many car owners overlook fuel quality. Poor-quality gasoline increases carbon deposits, which roughens the intake pipe walls, affecting air intake and mixture quality, leading to a sharp rise in fuel consumption. Therefore, gasoline quality should not be ignored. Regular maintenance at a 4S shop is a forward-looking investment, ensuring normal vehicle performance and saving unnecessary future expenses.
