What is the difference between CVVT and CVT engines?

CVVT and CVT engines differ as follows: 1. CVT: It is a type of transmission. Directly translated, it means continuously variable transmission, which is a stepless gearbox with no specific gear positions. In operation, it is similar to an automatic transmission, but the change in speed ratio differs from the gear-shifting process of an automatic transmission—it is continuous, ensuring smooth and uninterrupted power delivery. 2. CVVT: It is a technology applied to engines. Translated into Chinese, it means continuously variable valve timing mechanism, one of the many variable valve timing technologies gradually adopted in modern cars in recent years. For example, BMW calls it Vanos, Toyota refers to it as VVTI, and Honda names it VTEC. Their goal is to match the optimal valve overlap angle (valve timing) under different engine operating conditions, although the methods of achieving this vary. 3. Commonality: Both are developed to enhance fuel economy and driving smoothness in automobiles.

Can a car pass the annual inspection after an engine replacement?

Replacing the engine does not prevent a car from passing the annual inspection, but it is necessary to first complete the modification registration at the vehicle management office; otherwise, the inspection cannot be passed. According to the motor vehicle registration regulations, if a registered motor vehicle undergoes any of the following changes, the owner must apply for modification registration at the local vehicle management office: changing the body color or replacing the engine. If the engine is replaced without completing the modification registration at the vehicle management office, the vehicle will not pass the annual inspection. Documents required for engine replacement modification registration include: the vehicle license, vehicle registration certificate, motor vehicle modification registration application form, motor vehicle registration business process record, owner's identity proof, engine origin certificate, safety technical inspection certificate, and criminal inspection certificate.

What's the reason for poor air conditioning cooling in BMW 3 Series?

Poor air conditioning cooling in BMW 3 Series may be caused by refrigerant leakage; reduced heat dissipation capacity of the condenser; blocked air ducts or dirty air conditioning pipelines; prolonged use of external circulation, etc. It is recommended to go to a professional repair shop for inspection and treatment. BMW (Bavarian Motor Works), the full Chinese name is Bayerische Motoren Werke AG, a German luxury car brand. BMW's car series include i, X, Z, and pure number models, with several series such as 1, 2, 3, 4, 5, 6, 7, 8. The following are the functions of car air conditioning: 1. Temperature adjustment: This is the main function of car air conditioning. In summer, the cooling system produces cold air to cool the cabin; in winter, except for large commercial vehicles that use independent combustion heaters for heating, other vehicles basically use the car's waste heat for heating. 2. Humidity adjustment: Humidity has a great impact on the comfort of passengers in the car. The humidity in the cabin should generally be maintained at 30%-70%. Ordinary car air conditioners do not have the function of adjusting the humidity inside the car, only through the use of ventilation devices or high-end luxury cars equipped with integrated heating and cooling air conditioners. 3. Airflow adjustment: The speed and direction of airflow greatly affect human comfort. If blowing directly, when the temperature is suitable, the speed should be limited to a certain range. The speed can be appropriately changed according to the passenger's living environment, age, health status, and cold and heat habits. 4. Air purification: The air quality in the cabin is an important guarantee of comfort.

Do Cars Need to Display Insurance Stickers Now?

Currently, cars are required to display insurance stickers. After purchasing compulsory insurance for the vehicle, the insurance sticker should be immediately affixed to the right side of the front windshield. Although some regions have implemented electronic tags, they are not yet widely used, so displaying the vehicle insurance sticker is still necessary for road use. If the insurance sticker is lost, it must be reissued by the insurance company where the policy was purchased. You need to bring the vehicle's registration certificate and the compulsory insurance policy. Once reissued, the sticker should be directly affixed to the right side of the windshield. Losing the insurance sticker requires prompt reissuance; otherwise, driving the vehicle is considered illegal and may result in penalties. In case of an accident, the insurance company has the right to deny claims. According to the Road Traffic Safety Law, failure to display the insurance sticker may result in a one-point deduction from the driver's license and a fine.
