What are the reasons for an automatic transmission car not moving when releasing the brake in reverse?

What is the appropriate tire pressure for small cars in summer?

In summer, small cars generally require the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts.

What is the fuel tank capacity of the Cullinan?

The fuel tank capacity of the Cullinan is 100 liters, which is the officially announced data. The Cullinan uses 95-octane fuel, with a fuel consumption of 14.9L per 100 kilometers. A full tank can provide a range of approximately 671 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit, and there is additional space from the safe limit to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Can spark plugs with different thread lengths be used?

Spark plugs with different thread lengths cannot be used because mismatched models and varying discharge gaps can cause issues such as engine shaking, difficulty in acceleration, and increased fuel consumption. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order and reattach the cover. Damaged spark plugs can directly lead to issues like ignition system leakage, increased fuel consumption, reduced power, and most importantly, difficulty in starting the engine, affecting normal vehicle operation. Severe spark plug erosion—such as scarring at the top, broken or melted electrodes—indicates that the spark plug is damaged and should be replaced.

What to Do if the Tire Tread is Cut?

Tire tread cuts can be minor or severe. If the cut is minor, the tire can still be used normally. However, if the cut is severe, it is recommended to replace the tire or have it repaired before further use. If the damaged area is particularly large, repairs may not be effective, and there could be safety risks, so immediate replacement is advised. Here are the details: 1. Immediate Replacement: If the tread groove is cut by 4mm, the tire should be replaced immediately. Although the tread is thicker than the sidewall, the total thickness of the tire tread is only 13mm, with 7mm for the tread depth and 6mm for the crown. A 4mm cut in the groove means the remaining thickness is only 2mm, which poses a safety hazard, so replacement is recommended. 2. Remove Debris: To minimize the risk of tread cuts, regularly remove small stones lodged in the tire tread. Sharp stones in the tread grooves are the main cause of tread cuts. Additionally, trapped stones increase road noise, reduce the tire's drainage and grip performance, and extend braking distances, increasing the risk of hydroplaning in wet conditions.

Which BYD new energy vehicle has the longest range?

The BYD Han EV Super Long Range Premium Edition has an official range of 605km as certified by the Ministry of Industry and Information Technology. Below are the relevant details: 1. Fast charging time: The fast charging time is 0.42 hours; the maximum power of the four-wheel-drive high-performance version reaches 363kw, with a maximum torque of 680N.m. 2. Flagship sedan: The BYD Han is positioned as the brand's flagship sedan, available in both pure electric EV and hybrid DM versions. The two versions have some differences in exterior design. The EV version features a fully enclosed grille, which aligns more with pure electric vehicle design, with sharp lines, while the DM version adopts the family's Dragon Face design. Performance is undoubtedly the biggest highlight of the BYD Han. The hybrid DM version is powered by a 2.0T turbocharged engine combined with an electric motor, achieving a combined fuel consumption of 1.4L per 100km, with an official 0-100km/h acceleration time of just 2.9 seconds, showcasing extremely strong performance.

How Long Can a Car Drive Continuously?

A car can drive continuously for 500-800 kilometers as long as there is fuel in the tank. Generally, engines undergo a 500-hour non-stop test. However, the driving range may vary depending on the vehicle. Precautions for long-distance driving: Check the engine oil, transmission fluid, clutch fluid, power steering fluid, brake fluid, coolant, and windshield washer fluid, and top up or replace them if necessary. Inspect for leaks in oil pipes, water pipes, and seals, and check rubber hoses for aging, cracking, or wear. Examine all component connections for looseness and repair or replace as needed. Check the battery display window for voltage status, ensure the battery is securely fastened, and inspect terminals for looseness or corrosion. Charge, tighten, or rinse the positive and negative terminals with hot water as required. Monitor all warning and indicator lights on the dashboard, as well as all vehicle lights, and address any malfunctions accordingly. Inspect tire tread wear, check for foreign objects in the tread, examine the tire surface and sidewalls for damage, and ensure all tire pressures are normal. Perform preventive replacement or maintenance as needed.
