What's the Difference Between Tesla All-Wheel Drive and Rear-Wheel Drive?

What to do if the wheel hub of the Qashqai is scratched?

If the wheel hub of the new Qashqai is scratched, it needs to be analyzed based on the actual situation. As long as it is not very serious and does not affect normal driving, it can be completely ignored; however, if the scratch is very severe, the wheel hub can only be repaired or directly replaced. Whether to repair or replace it needs to be determined after a professional inspection. In most cases, the new Qashqai is an urban driving and control SUV launched by Dongfeng Nissan, with dimensions of 4315mm in length, 1783mm in width, and 1606mm in height, and a wheelbase of 2630mm. The exterior of the new Qashqai adopts Nissan's new V-Motion design language, featuring a new-style 'V' grille on the front face, accented with chrome trim, and redesigned headlights on both sides, which are slender in shape and equipped with lenses inside.

How Many Cars Can One Person Buy Under Their Name?

There is no explicit regulation on how many cars one person can purchase under their name; individuals can own as many cars as they wish. However, in cities with license plate restrictions, if one does not have a license plate quota, they cannot register a newly purchased car. Most people only have one car registered under their name. Some cities implement license plate restriction policies to control the growth rate of motor vehicle ownership, as rapid increases can lead to traffic congestion. When registering a new vehicle, any existing cars under the owner's name must have passed annual inspections and have all traffic violations resolved, with no illegal activities. If any car has not been inspected for three years and has not been deregistered, the new car cannot be registered. The taxes for purchasing a new car under an individual's name are not affected by the number of existing vehicles and are charged at the standard rate.

What to Do If the Crankshaft Bolt Is Too Tight?

The solutions for a crankshaft bolt that is too tight are: 1. Pour a little oil on the bolt and then turn it counterclockwise; 2. First heat the bolt with a conductive material, let it cool, and then turn it; 3. Dip a screwdriver in a little 502 glue, bond it to the bolt, and then turn it open; 4. Spray rust remover on the bolt to remove rust before loosening it. The crankshaft is an important component in the engine, bearing the force transmitted by the connecting rod and converting it into torque, which is output through the crankshaft to drive other engine accessories. The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads.

Can Vehicle Inspection and Pickup Be Done on the Same Day?

Vehicle inspection and pickup can be done on the same day. When picking up the car, pay attention to checking the vehicle's exterior, interior, tires, glass, lights, engine, and mileage. Pickup precautions: 1. Exterior: When picking up a new car, inspect the exterior under sufficient lighting to check for color differences in the paint and any scratches; 2. Interior: Check if the car seats have wrinkles, if there is any unusual odor inside the car, and if there is dirt in the interior corners; 3. Tires: Inspect the car tires for tread hairs, normal wear patterns, and sufficient tire pressure; 4. Glass: Check the production date of the car glass. The production dates of car glass may vary, but they should not exceed one year; 5. Lights: Verify that the car's headlights, taillights, turn signals, brake lights, etc., are functioning properly; 6. Engine: Start the car and check if the engine has any abnormal vibrations or unusual noises.

What Causes a Motorcycle to Suddenly Stall and Fail to Start?

The reasons for a motorcycle suddenly stalling and failing to start include abnormal fuel supply, excessively high engine temperature, and electrical circuit failure. Below are detailed explanations and solutions for these issues: Abnormal Fuel Supply: Before stalling, the rider may notice a gradual loss of power leading to an automatic stop. If the fuel tank has fuel, check whether there is fuel in the carburetor. If there is no fuel, the fuel line from the tank to the carburetor may be clogged and should be cleaned and unclogged. If the carburetor has fuel but the engine still fails to start, inspect whether the carburetor fuel filter is blocked or if the main jet is dirty. If the carburetor has fuel and the engine starts, it indicates an undetected fault in the fuel system. The fuel supply system must be thoroughly unclogged; otherwise, the engine stalling issue may recur. Excessively High Engine Temperature: Overheating and poor lubrication can cause the piston and cylinder to seize, leading to stalling. Signs before stalling include a gradual drop in power followed by a sudden stop. Check whether there is lubricating oil in the crankcase. If the oil level is low or absent, inspect the oil pan or drain plug for leaks and refill with the specified lubricating oil. If leakage is not the issue, check whether the lubricating oil is excessively depleted and replenish or replace it promptly. Electrical Circuit Failure: Sudden stalling due to electrical failure usually occurs without any prior engine abnormalities. Causes of sudden power loss typically involve wiring issues, such as loose or disconnected connectors, severed wires, or short circuits. For example, a faulty ignition coil may result from a loose connection, causing intermittent spark. Inspect all connectors, clean off any oil residue, and enhance the clamping force of the connector tabs and sockets to ensure stable contact. If the trigger coil is faulty due to a loose wire connection, reinforce the solder joints to eliminate potential cold solder issues.

What Transmission Does the Kuga Use?

The Kuga utilizes a transmission co-developed by Ford and General Motors, known for its high reliability. General Motors was founded on September 16, 1908, and globally manufactures and sells vehicles under brands such as Buick, Chevrolet, Cadillac, GMC, Wuling, Baojun, and Holden, among others. The Kuga is equipped with a 6-speed automatic manual transmission. Essentially, an automatic manual transmission is a traditional AT or CVT transmission enhanced with manual shifting capabilities, designed to add driving pleasure to automatic vehicles. When using the Kuga's transmission in daily driving, the following points should be noted: Do not delay transmission fluid changes for extended periods. Prolonged intervals can damage internal components like bearings and the transmission housing. Avoid coasting in neutral for long durations. While manual drivers often coast in neutral to save fuel, doing so in an automatic can cause overheating and jerky shifts when re-engaging Drive (D) mode. Never shift into Drive (D) or Reverse (R) before the vehicle has come to a complete stop. Aggressive gear changes while moving can severely damage transmission gears, leading to long-term issues like gear grinding. Refrain from frequently climbing steep hills in Drive (D) mode. Automatic transmissions may overheat under heavy load or upshift prematurely, causing power loss. Use manual mode to lock lower gears or engage Sport mode for protection. Do not tow the vehicle long distances. In case of breakdowns, always use a flatbed tow truck with the transmission in Neutral (N). Towing via ropes or with driven wheels on the ground is prohibited.
