Why does the fuel consumption reach 20 when starting the car?

What are the main ingredients of carburetor cleaner?

Carburetor cleaner, its characteristics and preparation method: a. Formula: Methanol 12%, Acetone 10%, Toluene 38%, 200# solvent oil 40%. b. After preparing the above stock solution formula, add the propellant raw material high-pressure propane. The ratio of stock solution to propellant is 6:4. The method involves proportionally preparing the stock solution and filling it into an iron can, then adding and thoroughly mixing the propellant before packaging the final product. The functions of carburetor cleaner are as follows: 1. Cleaning: Effectively removes oil sludge and other contaminants from throttle valves and engine component surfaces; 2. Decarbonization: Effectively eliminates gum deposits and carbon buildup in throttle valves, intake manifolds, and exhaust gas recirculation systems; 3. Penetration: Can be used as a loosening agent; 4. Rust prevention: Spraying on metal surfaces can prevent rust for a certain period; 5. Energy saving: Improves starting performance, enhances acceleration, eliminates idle instability, and reduces emissions.

Can the car owner be absent during vehicle transfer?

Car owners do not need to be present in person for vehicle transfer. A proxy can handle the process by presenting the original ID card of the owner, the original ID card of the proxy, and other required transfer procedures. When transferring vehicle ownership, relevant procedures must be completed, including the submission of a legally valid power of attorney. Both parties involved should also prepare the necessary materials to ensure a smooth vehicle transfer process. Documents required for vehicle transfer: Provide the original "Motor Vehicle Registration, Transfer, Cancellation, or Inbound Application Form." Provide the original and a copy of the current motor vehicle owner's identity proof. Provide the original or original and copy of the proof of motor vehicle ownership transfer. Provide the original vehicle license. Provide the original motor vehicle inspection record form (with the standard vehicle photo and chassis number rubbing attached). Provide the original "Certificate of Release from Customs Supervision for Motor Vehicles under Customs Supervision of the People's Republic of China" or the original customs-approved transfer certificate (for customs-supervised motor vehicles). Provide the original motor vehicle registration certificate. Provide one standard vehicle photo. Provide the "Power of Attorney" and the agent's identity proof (for motor vehicle registration and related business applications handled by an agent).

Are there any fees for vehicle deregistration?

There are no fees required for vehicle deregistration. To deregister a vehicle, you can go to the local vehicle management office. If there is a nearby traffic police branch, you can directly visit their office to complete the deregistration without having to queue for fine payments. There is a separate window for this process. Before processing, the staff will ask if you have a certificate issued by the public security bureau for stolen vehicles, as well as the online-verifiable police report. The official seals on these documents cannot be photocopied, but the supporting documents can be. The difference between vehicle deregistration and scrapping: 1. Vehicle deregistration: Pertains to the vehicle's registration information, essentially canceling the vehicle's registration record. This mainly applies when the vehicle meets the national mandatory scrapping standards, is lost, is no longer used within China, or is returned due to quality issues. The vehicle owner must apply for deregistration. 2. Vehicle scrapping: Pertains to the vehicle's operational lifespan, meaning when the vehicle reaches the prescribed service life, the vehicle itself is scrapped. However, if the owner does not deregister it, the vehicle's information will still remain on record.

Is driving at 60 km/h at a traffic light intersection considered speeding under the new traffic regulations?

The new traffic regulations do not explicitly specify the maximum speed limit when passing through an intersection. If the speed limit for that section of the road is 60 km/h or below, driving at 60 km/h is not considered speeding. Drivers should not exceed the speed limit of the road section when passing through a traffic light. Generally, the speed when passing through an intersection should be around 30-60 km/h. However, on the other hand, traffic rules or the subject one exam also clearly stipulate that drivers should slow down and yield to pedestrians when passing through intersections or crosswalks. If the speed is too high, it can easily lead to tragedies due to insufficient braking time. The following practices are safer when encountering an intersection: 1. Slow down in advance: When approaching an intersection, drivers should slow down in advance, observe the road, and then pass through at a relatively low speed. 2. When passing through an intersection at night: Remember to switch from high beams to low beams. 3. Pay attention to pedestrian movements: Anticipate pedestrian actions in advance. 4. When turning at an intersection: If there are heavy vehicles like dump trucks or lorries on the outer side, smaller vehicles turning on the inner side should yield, as heavy vehicles have more blind spots.

What causes the clicking sound when starting a car after it has been parked for several days?

Because of ignition delay, unburned gasoline is just discharged into the exhaust pipe when the spark plug ignites, and the sound is produced when the atomized gasoline is ignited in the exhaust pipe. This is mainly due to the vehicle being parked for too long, causing the battery to drain. Starting the car after 7 or 8 attempts is considered a good situation. Generally, if the vehicle remains unused for an extended period, it is best to charge the battery every three days and let the engine idle for about 10 minutes. If the car has aftermarket navigation systems or similar large electrical accessories, the power consumption will be even more severe. Below is additional information: 1. The abnormal sound only occurs during idling or low-speed operation. Possible causes include: excessive clearance between the piston and cylinder wall; overly tight piston pin or connecting rod bearing assembly; excessive clearance between the tappet and its guide hole; wear on the camshaft profile; sometimes, a loose starter pulley causing noise (more noticeable during speed changes). 2. When maintaining a certain speed, the sound becomes chaotic, and brief noises occur during rapid deceleration. Possible causes include: cracked camshaft timing gear or loose fixing nut; broken crankshaft; loose piston pin bushing; excessive axial clearance of the camshaft or loose bushing. 3. The abnormal sound appears during rapid acceleration and persists during high-speed operation. Possible causes include: loose connecting rod bearing, melted or mismatched bearing shell; loose crankshaft bearing or melted bearing shell; broken piston pin; broken crankshaft.

How Long Does It Take for a Car to Be Delivered from the Production Line to the 4S Store?

Under normal circumstances, it generally takes about a month for a vehicle to be delivered from the production line to the 4S store, depending mainly on the transportation distance and the efficiency of the staff. Typically, it takes 10 to 15 days, but if the model is in short supply or resources are tight, it can take up to 3 months. Additionally, the delivery time is also affected by peak and off-peak seasons, with peak seasons being faster. If the manufacturer's location is close to the 4S store, delivery will also be quicker. Below is a detailed explanation: 1. Order: It takes a certain amount of time for a new car to arrive at the store. Generally, after a consumer places an order, the 4S store will make a plan based on the order and report it to the manufacturer. Once confirmed, the vehicle can be shipped, which usually takes at least 10 to 15 days. The 4S store will communicate this timeframe with the consumer. For popular models that are in high demand and low inventory, the wait time can be longer. For example, in recent years, small-displacement and new energy vehicles have been particularly popular and in high demand, leading to insufficient inventory at 4S stores, which extends the delivery time for consumers. 2. Proximity Principle: Since large-brand vehicle manufacturers are not limited to just one, vehicle sources are diversified, and delivery is based on the proximity principle. For less popular models, some dealers may directly purchase them for resale, which lowers the purchase price, increases profits, and makes the delivery time faster and more convenient for consumers.
