What to Do If the Wheel Rim Is Scratched?

Here are the repair methods for scratched wheel rims: 1. Clean the wheel hub to remove stains; 2. Apply paint and oil. You can use adhesive tape around the scratched area in advance to prevent accidental application to other parts; 3. After it is completely dry, use water-resistant paper dipped in soapy water to apply, polish with a mixing machine, and then wax it. If the wheel hub is only scratched on the surface, it will only affect the appearance and will not impact the performance of the car tires. However, if the primer is exposed after scratching, the scratched area will wrinkle and the scope will gradually expand, leading to rust and corrosion over time. If the edge of the wheel hub is scratched, it should also be repaired promptly. In severe cases, it may cause the tire to not fit tightly, resulting in air leakage.

What is the standard size of a parking space?

According to the "Specifications for Setting On-Street Parking Spaces in Urban Roads," the standard size of a general parking space is determined by the size of the vehicle. Small parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. A single-lane turning lane should be no less than 3.5 meters wide, while a double-lane turning lane should be no less than 5 meters wide. The turning area should accommodate a vehicle's need for a one-time turn. For safety or to accommodate medium and large vehicles, the space is often set to 6 meters or more. Details are as follows: (Length ≤ 6m, width ≤ 1.8m) vehicles: The minimum spacing between vehicles should be no less than 0.5 meters, and the spacing between the vehicle and walls or the ends of the parking space should also be no less than 0.5 meters. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m) vehicles: The minimum spacing between vehicles should be no less than 0.7 meters. Small vehicle parking space: Length should be ≥ 5 meters, width 2.2-2.5 meters. Large vehicle parking space: Length 7-10 meters, width 4 meters, depending on the vehicle model. According to the "Architectural Design Code for Garages," the specific dimensions for small car parking spaces in indoor garages are as follows: The design dimensions for small cars are 4.8m (length) x 1.8m (width) x 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) x 2.4m (width), with a minimum lane width of 5.5m in front of the parking space. The minimum distance between small cars and side walls should be 0.6m, and the minimum distance from front and rear walls should be 0.5m. Modern underground garages have large floor areas and numerous parking spaces. To ensure smooth vehicle movement, the driving lanes are planned to be relatively wide. As the horizontal passage dedicated to parking spaces, the driving lane accounts for the primary floor area allocated to parking spaces and can occupy 50% or more of the total parking space floor area. Parking space arrangements can be categorized into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Details are as follows: Parallel parking space: Standard length is 6 meters, width is 2.5 meters. Angled parking space: Diagonal length should be 6 meters, width 2.8 meters, with a vertical distance of 2.5 meters between the two angled lines. Perpendicular parking space: Length should be ≥ 5 meters (typically 6 meters), width 2.5 meters. The optimal standard size is 2.5m x 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces should not be set on roads with a width of less than 6 meters for motor vehicle traffic. Pedestrian crossings, expressways, and main roads are also prohibited from having parking spaces. Within urban road areas, government authorities may designate parking spaces where pedestrian and vehicle traffic is not obstructed. On-street parking spaces should avoid interfering with non-motorized vehicle traffic and should not encroach on non-motorized vehicle lanes. They should not be set near intersections, building entrances, or bus stops. Vehicle types and parking durations should be specified and indicated with signs. Measures should be taken to avoid affecting motor vehicle traffic. Additionally, on-street parking spaces should not be equipped with ground locks to prevent private occupation. Roads where parking is prohibited may have barriers, posts, or blocks installed on one side. When parking spaces are removed or canceled, all related signs, markings, and management facilities should be promptly cleared to prevent continued parking and ensure road safety. Off-street public parking lots should not have on-street parking spaces within a 200m~300m radius. Quantitative regulations for on-street parking spaces: The "Specifications for Setting On-Street Parking Spaces in Urban Roads" provide quantitative rules based on road width. For two-way roads: if the actual road width exceeds 12 meters, parking spaces may be set on both sides; if between 12m and 8m, parking spaces may be set on one side; if less than 8m, no parking spaces should be set. For one-way roads: if the actual road width exceeds 9 meters, parking spaces may be set on both sides; if between 9m and 6m, parking spaces may be set on one side; if less than 6m, no parking spaces should be set. For disabled parking spaces, the specifications require that on-street parking spaces should include disabled parking spaces, accounting for no less than 2% of the total. If there are more than 20 parking spaces, at least one disabled parking space should be provided. Parking space marking colors: White: Paid parking spaces; Blue: Free parking spaces; Yellow: Reserved parking spaces; Time-limited parking spaces: Dashed border, 10cm line width; the permitted parking duration should be marked inside the border, with numbers 60cm high. Disabled parking spaces: Special markings; yellow grid lines on both sides indicate no-parking zones for boarding/alighting, and other vehicles must not occupy these spaces. The pavement marking should indicate exclusivity. Yellow grid lines: 120cm width; outer line width: 20cm; inner fill line width: 0cm; angle with outer line: 45°; outer line length should match the parking space marking length. Prohibited areas for on-street parking spaces: Fire lanes, sections with no-parking signs/markings, and construction zones affecting traffic; Roads designated for disaster relief and emergency evacuation; Sidewalks (if set, must not encroach on blind paths); Near building entrances; Intersections, railway crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, tunnels, and sections within 50m of these locations; Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for vehicles using these facilities); Within 20m of road junction channelization areas; Near underground utility access points (water, electricity, gas) and within 15m of these locations; Within 200m of off-street parking lot entrances.

How to Use a Vernier Caliper?

Align the zero marks of the vernier and the main scale to begin measurement. Hold the main scale with your right hand and move the vernier with your thumb, while holding the object to be measured with your left hand, positioning it between the outer measuring jaws. When the object fits snugly against the jaws, you can take the reading. Below is a related introduction to vernier calipers: 1. Composition: A vernier caliper mainly consists of two parts - the main scale and the sliding vernier scale attached to it. The main scale is typically graduated in millimeters, while the vernier scale has 10, 20, or 50 divisions. 2. Usage Precautions: Vernier calipers are relatively precise measuring tools, so handle them gently and avoid collisions or dropping them on the ground.

What is the fuel consumption of the NK400?

If frequently driven in urban areas, the NK400's fuel consumption is around 5 liters per 100 kilometers. For long-distance travel, the fuel consumption is approximately 4 liters per 100 kilometers. The main factors affecting fuel consumption are as follows: 1. Unnecessary increase in vehicle load. Many new car owners tend to pile on numerous decorations and exterior accessories onto their vehicles. 2. Frequent braking and starting. Apart from the vehicle's design and engine factors, the primary cause of wasted fuel is the driver's habits, with frequent sudden braking and rapid acceleration being the biggest contributors to increased fuel consumption. 3. High speed in low gear. One of the biggest driving misconceptions is driving at high speeds in low gears. Tests have shown that driving long distances at high speeds in 3rd gear increases fuel consumption by 10% compared to normal driving in 4th gear, and using 2nd gear instead of 3rd gear further increases fuel consumption.

Do Used Cars Require Purchase Tax?

If the original owner has already paid the purchase tax, then the used car you buy does not require payment again. Below is a related introduction to the role of vehicle purchase tax: 1. Reasonably raising construction funds: By levying vehicle purchase tax, the state participates in the redistribution of national income, effectively converting a portion of consumer funds into fiscal funds, thereby raising more funds for the state to meet the needs of exercising its functions. 2. Standardizing government behavior: A socialist market economy requires a sound macroeconomic regulatory system to ensure rapid, coordinated development and healthy operation. Firstly, due to the fundamental difference between taxes and fees, replacing fees with taxes and levying vehicle purchase tax helps to clarify the relationship between taxes and fees.

What to Do When the Keyless Entry System Fails?

Solutions for keyless entry failure: If the issue is caused by a dead car key battery, simply replace it with a new coin cell battery. However, if this is not the reason, the only solution is to take the car to a 4S shop for inspection. Below are some tips for preserving smart keys: 1. Do not store them with electronic devices: Since smart keys use low-intensity radio waves, avoid placing them near electronic products or devices such as radios, TVs, computers, and microwaves. These are considered the 'nemesis' of smart keys. Electromagnetic waves not only drain the battery but can also interfere with the smart key's chip, eventually causing it to malfunction. 2. Avoid rough handling: Most smart keys have fragile internal circuits that can easily be damaged by strong impacts. Additionally, if a smart key gets wet, the internal circuits may short-circuit, leading to remote control failure. Also, avoid placing the smart key under the windshield or in high-temperature environments exposed to direct sunlight. 3. Do not keep the spare key in the car: Avoid storing the spare key inside the car or together with the smart key.
