Can You Wash Your Car Immediately After a High-Speed Run?

You should not wash your car immediately after a high-speed run; wait until the car has cooled down. After prolonged high-speed driving, both the brakes and the engine are in a very hot state. If water comes into contact with the hot engine cover or brake discs, thermal expansion and contraction can affect the vehicle, potentially causing minor issues like steering wheel vibration or severe problems such as brake system failure, compromising driving safety. Washing precautions: 1. Avoid washing the car before the engine has completely cooled down, as this can lead to premature aging of the engine. 2. Avoid washing the car under direct sunlight, as this can leave dried water spot marks on the body. 3. Avoid washing the car in extremely cold weather, as water freezing can cause the paint film to crack. 4. Avoid using anything other than soft water for washing, including hot water, alkaline water, or hard water, as these substances can damage the paint. Using hard water can leave marks and a film on the car's surface after drying.

Will the warranty still be valid after installing a reverse camera?

Installing a reverse camera will not void the vehicle's warranty, but the aftermarket product itself is not covered by the original warranty. Additionally, it's important to note that any related malfunctions caused by self-modified wiring will also not be covered under warranty. The shop that installed the equipment is responsible for the warranty of the aftermarket product. The reverse camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. Whether in terms of structure and appearance or performance, current products each have their own characteristics. The most commonly used types are digital display, screen display, and multi-function rearview mirror display.

How does a car air conditioner cool?

The cooling principle of a car air conditioner is as follows: The refrigerant absorbs heat in the evaporator in a liquid state, and the low-temperature liquid absorbs the latent heat of vaporization to become a gaseous refrigerant, which is then sucked in and compressed by the compressor. The compressed gas increases in both pressure and temperature before flowing into the condenser. Car air conditioners are all air-cooled, and the refrigerant gas is condensed in the condenser. The condensed high-temperature and high-pressure liquid is stored at the bottom of the condenser and in the liquid reservoir. The heat released during condensation is carried away by the fan and dissipated outside the car. When the high-temperature and high-pressure liquid flows through the expansion valve, it returns to a low-temperature and low-pressure liquid state and re-enters the evaporator to absorb the latent heat of vaporization for cooling, thus completing the refrigeration cycle.

Standard Dimensions of Roadside Parking Spaces?

According to the "Specifications for Setting On-Street Parking Spaces on Urban Roads," the standard dimensions of general parking spaces are determined based on vehicle size. Small parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. The width of a single-lane turning lane should be no less than 3.5 meters, while a double-lane turning lane should be no less than 5 meters. The turning area should accommodate a vehicle's one-time turning needs. For safety or to accommodate medium and large vehicles, parking spaces are often set to 6 meters or longer. Details are as follows: (Length ≤ 6m, width ≤ 1.8m): The spacing between vehicles should be no less than 0.5 meters, and the distance between a 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): The spacing between vehicles should be no less than 0.7 meters. Small vehicle parking space: Length ≥ 5 meters, width 2.2–2.5 meters. Large vehicle parking space: Length 7–10 meters, width 4 meters, depending on the vehicle type. Per the "Architectural Design Specifications for Parking Garages," the dimensions for small car parking spaces in indoor garages are as follows: The external design dimensions of small cars are 4.8m (length) × 1.8m (width) × 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) × 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small cars and side walls should be 0.6m, and the distance to front/rear walls should be 0.5m. Modern underground garages have large floor areas and numerous parking spaces. To ensure smooth vehicle movement, driveways are planned to be relatively wide. Driveways, as horizontal passages dedicated to parking spaces, account for a significant portion of the floor area—often 50% or more of the total parking space 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 6m, width 2.5m. Angled parking space: Diagonal length 6m, width 2.8m, with a vertical distance of 2.5m between the two angled lines. Perpendicular parking space: Length ≥ 5m (typically 6m), width 2.5m. The optimal standard size is 2.5m × 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces are prohibited on roads with a width of less than 6m, as well as on crosswalks, expressways, and main roads. On urban roads, government authorities may designate parking spaces where pedestrian and vehicle traffic is not impeded. On-street parking spaces should not interfere with non-motorized vehicle passage or encroach on their space. They should not be set near intersections, building entrances, or bus stops. Parking restrictions (e.g., vehicle type, time limits) must be clearly marked with signs. Measures should be taken to avoid obstructing traffic flow. Additionally, on-street parking spaces must not have ground locks to prevent private occupation. Roads where parking is prohibited may feature barriers, bollards, or curbs. When parking spaces are removed, all related markings and signs must be cleared promptly to prevent illegal parking. On-street parking spaces should not be set within 200m–300m of off-street public parking lots. Quantitative rules for on-street parking space setup: The "Specifications for Setting On-Street Parking Spaces on Urban Roads" provide quantitative guidelines based on road width. For two-way roads: if the actual width exceeds 12m, parking spaces may be set on both sides; if between 12m and 8m, parking may be allowed on one side; if less than 8m, no parking spaces are permitted. For one-way roads: if the actual width exceeds 9m, parking may be allowed on both sides; if between 9m and 6m, parking may be allowed on one side; if less than 6m, no parking spaces are permitted. For disabled parking spaces, the specifications require that at least 2% of total parking spaces be designated for disabled use, with a minimum of one space if there are 20 or more parking spots. Parking space marking colors: White: Paid parking spaces. Blue: Free parking spaces. Yellow: Reserved parking spaces. Time-limited parking spaces: Dashed borders (10cm line width) with permitted parking times marked inside (60cm-high numbers). Disabled parking spaces: Special markings with yellow grid lines on both sides indicating no-parking zones for boarding/alighting. Other vehicles must not occupy these spaces. The yellow grid lines should be 120cm wide, with 20cm outer lines and 45° internal angles matching the parking space length. Prohibited areas for on-street parking spaces: Fire lanes, roads with no-parking signs/markings, or construction zones that impede traffic. Roads designated for disaster relief or emergency evacuation. Sidewalks (if set, must not encroach on tactile paving for the visually impaired). Near building entrances. Within 50m of intersections, railroad crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, or tunnels. Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for authorized vehicles). Within 20m of intersection channelization zones. Within 15m of underground utility (water, electricity, gas) access points. Within 200m of off-street parking lot entrances.

Are the Lingdong and Yuedong equipped with the same engine?

Lingdong and Yuedong are equipped with the same engine, both featuring a 1.6L naturally aspirated inline four-cylinder Gamma engine. The reason why the Yuedong is significantly longer than the earlier Hyundai i30 is primarily due to its body structure, which draws inspiration from the design style of the SAIC Volkswagen Lavida Tour, positioning it between a standard hatchback and a station wagon, thus offering a longer trunk space. The Lingdong measures 4610mm in length, 1800mm in width, and 1450mm in height, with a wheelbase of 2700mm. The Yuedong measures 4510mm in length, 1765mm in width, and 1470mm in height, with a wheelbase of 2650mm.
