What is the most fuel-efficient temperature to set the car air conditioning in summer?

Setting the car air conditioning to 26 degrees Celsius in summer is the most fuel-efficient. Directing the vents upward can cool the car quickly: Many friends feel that pointing the air vents directly at themselves makes them feel the coolest, but this actually prevents the overall temperature inside the car from dropping. Since hot air tends to rise and accumulate near the roof, directing the vents upward allows the cold air to rise, which helps lower the cabin temperature more quickly. Once the temperature drops, reducing the fan speed will naturally save fuel. It's best to alternate between recirculation and fresh air modes: When first turning on the air conditioning, start with the fresh air mode to expel stale air from the cabin. After the temperature has dropped, switch to recirculation mode to cool the interior faster. Alternating between these modes not only saves fuel but also enhances the driving experience.

Is It Legal to Buy a Vehicle with a Nominal Owner?

It is illegal to buy and use a vehicle with a nominal owner. Below is relevant information: 1. Definition: A vehicle with a nominal owner refers to a car that cannot be transferred to a new owner. Such a vehicle may be fully functional, with all necessary documents in order, including valid annual inspections and insurance, but ownership transfer is impossible. 2. Reasons: The vehicle's license plate registration location is too distant, making the transfer process costly; the vehicle may be used as collateral in debt settlements, possibly entangled in multiple debt cycles; the original owner has passed away without canceling the vehicle registration; in regions with purchase restrictions, the vehicle is sold along with the license plate; imported vehicles cannot be registered locally due to migration restrictions; some fraudsters may sell commercial vehicles converted to private use as nominal owner vehicles at low prices.

Can the original engine number be stamped when replacing an engine?

No. According to legal requirements, replacing an engine requires applying for a change registration at the local vehicle management office. The vehicle owner should apply for a change registration within ten days after the replacement. Circumstances requiring change registration: Changing the body color; replacing the engine; replacing the body or frame; replacing the entire vehicle due to quality issues; changing the use nature from commercial to non-commercial or vice versa; the owner's residence moving in or out of the jurisdiction of the vehicle management office. Required documents: The owner's original ID card; a safety inspection certificate issued by the inspection station; the original vehicle registration certificate and driving license; the replacement engine's qualification certificate, invoice, and import documents.

Why Does the Car's One-Button Start Fail to Ignite?

Introduction to reasons why the car's one-button start fails to ignite: 1. Steering wheel lock. The steering wheel lock is a simple anti-theft feature. When the car is turned off, turning the steering wheel from the centered position to a certain angle in one direction will cause it to lock with a "click" sound. In the locked state, the one-button start function does not work. 2. Gear not in P position. For automatic transmission vehicles (AT, CVT, AMT), the manufacturer's manual will indicate that the gear must be in the P position when starting the ignition. 3. Smart key battery dead. When the vehicle's smart key battery is dead, the key's transmission power is very low, making it difficult for the car's sensor to detect it, which prevents the one-button start from functioning.

What is a Same-Direction Lane?

Same-direction lanes refer to motor vehicle lanes where the direction of travel is the same. Same-direction lanes on highways: Highways typically have four same-direction lanes, with the second and third lanes being the middle lanes. Vehicles traveling at speeds above 110km/h should use the leftmost lane; those above 90km/h should use the middle lanes (lanes 2 and 3); the rightmost lane has a minimum speed limit of 60km/h. Motor vehicle lanes: Motor vehicle lanes are defined as the portion of the roadway (between curbs on urban roads or the paved surface on highways, designated for vehicle traffic) from the first lane divider line on the right to the center line (or geometric center line if no center line exists). Except under special circumstances, these lanes are exclusively for motor vehicle use.

What are the dimensions of the Touareg trunk?

The Touareg's trunk has a depth of 1020mm, which can be extended to a maximum depth of 1910mm when the rear seats are folded down. The minimum width is 1070mm, and the maximum width is 1390mm, with a height of 770mm. It comes standard with an electric trunk and adjustable rear suspension height inside the trunk, making it convenient to carry heavier items. The floor is not completely flat, and the wheel arches protrude slightly, but other aspects are satisfactory. Here is some additional information: 1. Brand History: The Touareg is an SUV produced by the German automaker Volkswagen. The name "Touareg" is derived from the Tuareg people, a nomadic ethnic group living around the Sahara Desert. 2. Interior Features: The Volkswagen Touareg maintains the overall layout of the current model, with added features such as Google Maps integration and an automatic collision avoidance system.

What Causes Slight Body Vibration at Idle Speed?

Causes of slight body vibration at idle speed include aging engine mounts, excessive carbon buildup, and fuel supply system malfunctions. Below are detailed explanations: Aging Engine Mounts: Deterioration of engine components, such as aging engine mounts. Engine mounts serve as the vibration damping system for the engine, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing noticeable shaking at idle. Excessive Carbon Buildup: Severe carbon deposits in the engine cylinders can clog spark plugs and valves, directly leading to vehicle vibration at idle. If the car's acceleration performance declines and the shaking persists, it's necessary to clean the engine cylinders. Fuel Supply System Malfunction: Unstable fuel pressure can cause inconsistent air-fuel mixture concentrations, resulting not only in vibration but also unstable idle speeds. It's advisable to replace the fuel filter and check the fuel pressure at the filter.
