Driving over a stone and hearing a loud bang is the sound of the stone colliding with the tire. Avoid driving on bumpy roads: When using your car, try to avoid deep potholes, and always slow down when driving over uneven surfaces or speed bumps. This reduces the impact on the suspension system. Driving over bumpy roads or speed bumps may alter the car's wheel alignment data, so it's important to regularly check and adjust the wheel alignment. Incorrect wheel alignment can lead to uneven tire wear or the car pulling to one side. Car shock absorbers: The shock absorbers in a car are wear-prone components. While they generally last a long time, their performance degrades over time. If you hit a large stone and hear a loud noise, it might be coming from the shock absorber. In some cars, shock absorbers may also start leaking oil as they age.

Difference between Harbor-Style Bus Bay and Emergency Parking Lane Icons

The differences between harbor-style bus bay and emergency parking lane icons are: 1. Usage difference: The emergency parking lane is provided on highways or first-class roads for vehicles to park temporarily in case of traffic accidents or mechanical failures while awaiting rescue. According to relevant regulations, there is an emergency parking lane every 750m on highways and first-class roads. Similar to the emergency lane, the emergency parking lane is only for emergency parking and should not be occupied arbitrarily. 2. Sign design difference: The emergency parking lane sign has dashed lines in the middle, while the harbor-style bus bay or passing bay sign does not have dashed lines in the middle, which requires careful distinction. When parking on the emergency parking lane, regardless of the reason, it is mandatory to place a triangular warning sign 150m behind the vehicle and turn on the hazard warning lights according to regulations, otherwise, it may result in penalties from traffic police.

Does prolonged idling have any impact on the car?

Prolonged idling does have an impact on the car, with the main effects being: 1. Increased fuel consumption; 2. More likely to form carbon deposits; 3. Can easily clog fuel injectors or even cause piston rings to seize; 4. Accelerates engine wear; 5. Worsens engine exhaust emissions, polluting the air. Keeping the car running without moving or accelerating is called stationary idling, where fuel is consumed only to maintain the engine's minimum operational requirements. It is recommended to avoid prolonged idling whenever possible. If you need to wait for more than 5 minutes or an extended period after parking, it is advisable to turn off the engine. If you accidentally leave the car idling overnight, you can drive at high speed for twenty minutes the next day to help expel the carbon deposits.

What is the maximum allowable modification for a car spoiler?

Modifying a car spoiler is not legally compliant. Currently, the "Motor Vehicle Inspection Work Regulations" have relaxed some restrictions on car modifications, but policies do not support spoiler modifications. Altering a car spoiler is considered a change to the vehicle's exterior appearance and is classified as a violation, hence it is not recommended. Below is more information about car spoilers: 1. Car spoilers are part of aerodynamic design. Generally, factory-installed spoilers on civilian vehicles are not overly exaggerated, and some even feature retractable spoilers. 2. When a car is traveling at high speeds, air passing over the spoiler can increase the vehicle's downforce (typically adding several dozen kilograms, with some even exceeding 100 kilograms), enhancing driving stability. 3. A well-designed spoiler can reduce air resistance, contributing to fuel efficiency to some extent.

Is it mandatory to display a novice driver sticker on a new car?

It is not necessarily required to display a novice driver sticker on a new car. Circumstances requiring the novice driver sticker: The novice driver sticker is specifically for new drivers who are within the probationary period of their driver's license. Regardless of whether the vehicle being driven is new or old, as long as the driver is in the probationary period of their license, they must display the novice driver sticker. This requirement is not inherently related to purchasing a new car. Legal provisions: According to Article 64, Clause 3 of the 'Regulation No. 123': Drivers within the probationary period must affix or hang a uniformly styled novice driver sticker at the rear of the vehicle. Failure to display this sticker, displaying a sticker that cannot be properly recognized, or using non-compliant stickers such as 'New Driver' or self-printed labels will be considered as not displaying the sticker and will result in a fine.

Can the engine high-temperature warning not exceed 10 minutes?

Engine high-temperature warning should not exceed 10 minutes. Detailed explanation of why high-temperature warning should not exceed 10 minutes: Prolonged idling operation of the engine can lead to excessive carbon buildup. During idling, the engine operates under low-temperature combustion conditions, so it's advisable to avoid idling for more than ten minutes. Disadvantages of prolonged idling include: 1. During idling, the oil pump operates at low speed, resulting in minimal oil pressure - the lowest point for engine lubrication. This leads to poor lubrication for bearing shells and other moving parts, increasing wear risk. 2. Idling engines produce higher CO and HC emissions. 3. The water pump operates at reduced speed, compromising the cooling system's heat dissipation capability, forcing reliance on electric cooling fans.
