The yellow engine light on the car dashboard indicates an engine malfunction, which can be caused by: 1. A clogged air filter restricting airflow; 2. Poor fuel quality leading to increased carbon deposits in the engine cylinders; 3. Faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines causing improper combustion of the air-fuel mixture; 4.

What is the Difference Between Large Trade and Small Trade Motorcycles?

Here are the main differences between large trade and small trade motorcycles: 1. Nature: Large trade generally refers to large trade vehicles. These are vehicles imported through formal customs channels, sold by authorized dealers, and subject to purchase tax payment and licensing, allowing for immediate name transfer and ownership changes. Small trade refers to small trade vehicles. These are vehicles imported under a certain tariff discount quota provided by the state to encourage investment, targeting foreign investors, overseas students, overseas Chinese, or enterprises with a certain amount of foreign investment. Such vehicles are referred to as small trade vehicles in the industry. 2. Features: Large trade vehicles must be declared with an import license (foreign-invested enterprises have import licenses), accompanied by a customs goods import certificate and a commodity inspection certificate from the import port. Currently, from import to individual purchase, an imported vehicle requires payment of tariffs, value-added tax, and consumption tax. The comprehensive tax rate for an imported vehicle is roughly equivalent to 70% of the vehicle's total price, which is why the price of large trade imported vehicles remains high. Small trade vehicles can be 10% to 15% cheaper than regular large trade vehicles, but within one year of import supervision, they can only be registered under the license plate of the foreign investor or foreign-invested enterprise's location. Only after one year can the name transfer and ownership changes proceed normally. 3. Responsibility: Large trade vehicles must, in accordance with China's national mandatory regulations, legally assume the original factory warranty; otherwise, they will face penalties such as import suspension. Small trade vehicles are imported by the applicant or importing unit based on their own usage principles, after applying to the national import regulatory authorities. Before import, they must declare that they will bear the risks associated with the vehicle's use themselves. The maintenance, warranty, and licensing of small trade vehicles are all the responsibility of the importer.

How Does a Car Run-Flat Tire System Work?

Precautions for using run-flat tires include: 1. Do not use cruise control; 2. Drive at reduced speed and turn on hazard lights; 3. Make slow turns and avoid sudden movements; 4. Immediately seek a repair shop for maintenance.
