Automatic transmission cars jerk and shake when starting due to transmission malfunctions. In such cases, it is necessary to visit a 4S shop or a professional repair facility to read the fault codes, which can help technicians quickly identify the faulty part and the cause of the issue. There are three common types of automatic transmissions in automatic cars: AT transmission, CVT transmission, and dual-clutch transmission. The AT transmission contains many planetary gears and relies on them for speed and torque variation. The CVT transmission is a relatively simple automatic transmission in structure. The dual-clutch transmission offers fast gear shifting and relatively high transmission efficiency.

What is the Function of an Automotive Oil Filter?

Automotive oil filter function: It filters out the majority of impurities in the engine oil, maintaining the cleanliness of the oil and extending its normal service life. Additionally, the oil filter should possess properties such as strong filtration capability, minimal flow resistance, and a long service life. The oil filter, also known as the oil element, is used to remove impurities like dust, metal particles, carbon deposits, and soot particles from the engine oil, thereby protecting the engine. During engine operation, metal shavings, dust, oxidized carbon deposits and colloidal deposits under high temperatures, water, and other contaminants continuously mix into the lubricating oil. The role of the oil filter is to screen out these mechanical impurities and colloids, keeping the lubricating oil clean and prolonging its service life. The oil filter should have the properties of strong filtration capability, minimal flow resistance, and a long service life.

How to Alternate Between High and Low Beams?

The method for alternating between high and low beams is as follows: 1. There is a lever located below the left side of the steering wheel. 2. Use your thumb and index finger to grasp this lever. 3. First, pull it backward (toward yourself), then push it forward (toward the front of the car). Repeat this back-and-forth motion twice. This will achieve the alternation between high and low beams. Relevant information about car lights is as follows: 1. Purpose of low beams: Low beams are designed for close-range illumination, with a wide coverage angle (160°) but a short projection distance, and the focus cannot be adjusted. 2. About low beams: Although low beams have an illumination distance of about 30 meters, they feature a very distinct cutoff line between light and dark.
