Why does the car make noise at 70 km/h but not at 80 km/h?

What is the speed limit for vehicles passing through villages and towns on national highways?

Normally, the speed limit on provincial and national highways is 80 km/h, but when passing through villages, towns, residential areas, or near schools, the speed limit is reduced to 60 km/h or 20 km/h. Speed limit regulations: Motor vehicles driving on the road must not exceed the maximum speed indicated by speed limit signs. On roads without speed limit signs, drivers should maintain a safe speed. National highways: These refer to major trunk roads with national political and economic significance, including important international highways, defense highways, roads connecting the capital with provincial, autonomous region, and municipal government seats, and roads linking major economic centers, port and station hubs, commodity production bases, and strategic locations. Cross-provincial expressways within the national highway system are constructed, maintained, and managed by specialized agencies approved by the Ministry of Transport.

Will I be photographed if I run a red light for one second?

You will not be photographed. Traffic light mechanism: The traffic signal control system mainly consists of a controller, timer, decoder, and second pulse signal generator. The second pulse generator serves as the standard clock signal source for the timer and controller in this system. The decoder outputs control signals for two sets of traffic lights, which drive the traffic lights to operate through the driving circuit. The controller is the main part of the system, controlling the operation of the timer and decoder. Specific regulations: If you encounter a red light with only one second remaining while driving and there are electronic eyes or probes, you will definitely be photographed. If you have already crossed the stop line, stop immediately and do not move further. Reversing is highly likely to cause a collision with vehicles behind or pedestrians crossing the road. Additionally, probes are designed to capture moving violations. Remaining stationary would not result in a penalty, but moving too far might get you photographed.

What Causes the Sunroof of Mistra to Not Close?

Here are the specific reasons why the sunroof of Mistra cannot be closed: 1. Component Aging: Press the sunroof switch button and observe the movement track of the sunroof to check for any obvious up-and-down fluctuations. If present, it is likely due to component aging, and the only solution is to replace the parts. 2. Presence of Debris Particles: After prolonged use, some debris particles may accumulate on the sliding rails. When the sunroof moves along these rails, friction with the debris can cause abnormal noises. Apply lubricant to both sides of the sunroof's sliding rails. 3. Loose Screws: Loose screws can lead to abnormal noises from the roof lining and the sunroof, and even pose a risk of the sunroof falling off. Tightening the sunroof screws can resolve this issue.

How to Determine if the VVT Timing Gear is Good or Bad?

With the engine turned off, open the upper cover of the valve chamber, then use a wrench to rotate the camshaft and observe if the VVT actuator shows any angular offset. If there is no offset, it indicates no problem; otherwise, any rotation suggests damage. Below is more detailed information: 1. Certain principles should be followed when repairing faults in the VVT gear. First, check if the timing is correct. Since VVT technology is developed based on basic timing, the basic timing usually does not have issues. Next, inspect whether the engine oil circuit is malfunctioning, which could prevent the VVT from operating normally. 2. If the VVT mechanism is found to be faulty, it is best to have it repaired or replaced directly at a 4S shop. When the VVT is faulty, the engine idle becomes unstable, fuel consumption increases, and the engine may suffer some damage. Therefore, timely repairs are necessary to avoid accidents.
