The ballast is installed beneath the bumper and headlight assembly. When the vehicle is moving forward, the incoming airflow through the grille helps cool the ballast, thereby reducing the risk of spontaneous combustion. Additionally, the ballast should not be installed too far away to prevent interference from other electrical devices that might affect its normal operation. The ballast is an essential component in HID lighting systems, also known as an electronic ballast. Its function is to instantly boost the vehicle's 12V voltage to 23,000V, using this high voltage to activate the xenon bulb, creating intense light between the electrodes and enabling the bulb to achieve high-brightness illumination.

Parallel parking: The land area for public parking lots is calculated based on the number of small car parking spaces. The minimum size for parallel parking spaces is 6 meters × 2.5 meters, and parallel parking is generally more commonly used. 2. Perpendicular parking: The land area for public parking lots is calculated based on the number of small car parking spaces. The minimum size for perpendicular parking spaces is 6.5 meters × 2 meters. Relevant legal provisions for underground parking spaces are as follows: Article 275 of the Civil Code of the People's Republic of China stipulates that the ownership of parking spaces and garages planned for parking within building areas shall be agreed upon by the parties through sale, gift, lease, or other means.

Can I continue driving if the Sagitar shakes after wading through water but then returns to normal?

If the vehicle shakes after wading through water, you must not continue driving. You should promptly take it to a repair facility for inspection and treatment to identify and resolve the cause of the shaking. The reasons for shaking after wading through water are as follows: 1. The engine's electrical components or wiring harness may have been submerged, causing signal loss or distortion, which leads to engine shaking. During repairs, inspect and confirm the faulty components, then proceed with treatment or replacement to resolve the issue. 2. If shaking occurs after wading through water, it is possible that water has entered the engine cylinders, causing damage to mechanical components such as the connecting rods. If these are not replaced, the deformed connecting rods may eventually break, leading to extensive damage to engine components like the cylinder block. The repair costs for such damage can be significantly higher.

Is the particulate filter of the Tayron 1.4T prone to clogging?

The particulate filter of the Tayron 1.4T is prone to clogging. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. The methods for handling clogged particulate filters differ between diesel and gasoline vehicles, as follows: For diesel vehicles, simply press the regeneration button in the car. The engine will then increase its RPM while stationary, and generally, the particulate filter will be cleaned in about ten minutes, resolving the clogging issue. For gasoline vehicles, the owner should first shift the car into S gear and then drive at high speed for a period of time. When the car is driven at high speed, the temperature of the exhaust pipe will rise, and the clogged particles in the particulate filter will be burned off, solving the clogging problem once the burning is complete. If the particulate filter is severely clogged and the above two methods do not resolve the issue, the particulate filter can be sent to an auto repair shop or 4S store for professional cleaning with specialized equipment.
