The main reason for increased car fuel consumption in summer is the use of air conditioning while driving, which can raise fuel consumption by approximately 20%. Below are explanations for other contributing factors: 1. Cooling System Demand: The radiator's cooling efficiency is often compromised in summer, leading to higher fuel consumption. 2. Brake System Issues: Problems such as brake pads not retracting properly increase driving resistance. Addressing these through maintenance can reduce fuel consumption. 3. Clogged Fuel System: Carbon buildup blocking the fuel system can be resolved by using fuel system cleaners to clean the injectors and throttle body, thereby lowering fuel consumption.

Can a used car be transferred in another city?

It is possible to transfer a used car in another city, but you first need to go to the location where the used car's license plate is registered to complete the transfer and file extraction procedures. However, before extracting the files, it is essential to confirm the used car admission standards of the destination city. Most areas require the vehicle's emissions to meet the National IV standard, and some places also have requirements regarding the vehicle's age. The process for transferring a used car to another city is as follows: 1. Check the local vehicle registration requirements to ensure the destination city accepts the vehicle; 2. Bring the necessary transfer documents (including IDs of both parties, the vehicle registration certificate, the driving license, and the engine number rubbing. The buyer must have a local ID or residence permit) and drive the vehicle to the vehicle registration service station to complete the outbound transfer and file extraction; 3. Once the files arrive, drive the vehicle to complete the registration procedures in the destination city.

How to Reapply for Lost Vehicle Documents?

There are mainly the following methods to reapply for vehicle documents: 1. Reapplication of the vehicle license must be processed at the vehicle management office: You need to take photos of the vehicle in the parking lot, fill out the "Motor Vehicle License and Plate Application Form," and provide the owner's ID card and a local temporary residence permit for non-local residents. Additionally, if the reapplication is handled by an agent, the agent's original ID card, a copy, and a power of attorney are required. For vehicles owned by organizations, the original and a copy of the organization code certificate and a power of attorney with the organization's official seal are needed. 2. Reapplication of the registration certificate: You need to go to a vehicle management branch for vehicle inspection and photography, then collect it at the vehicle management office. Required documents include the owner's original ID card, and a temporary residence permit for non-local residents. It can be obtained on the same day, but cannot be handled by an agent. For vehicles owned by organizations, the original organization code certificate and a power of attorney with the official seal are also required. 3. Reapplication of the purchase invoice: For vehicles over five years old, the owner can write a commitment letter on-site.

What Are the Reasons for a Car's Lack of Power When Climbing Uphill?

Common reasons for a car's lack of power when climbing uphill include a blocked fuel tank vent hole. Below are the relevant details: Common Causes: Partial blockage of the fuel tank switch, fuel filter, or the fuel line between the tank and the carburetor, which fails to meet the required fuel supply, leading to an overly lean air-fuel mixture and reduced engine power; incorrect ignition timing, where ignition occurs too early, causing premature combustion and detonation of the combustible mixture; severe wear of the piston, piston rings, or cylinder, increasing the clearance between them and reducing sealing performance, resulting in cylinder head leakage and decreased cylinder compression pressure. Solutions: Check if the air filter is clogged and clean it if necessary; inspect the throttle opening. The throttle should fully open when the accelerator pedal is pressed to the floor; examine the high-voltage wires, spark plugs, and whether the high-voltage spark is too weak.
