The reason the spark plug can't be unscrewed is due to using the wrong tool or incorrect force application. Spark Plug Replacement Interval: Under normal maintenance conditions, replace spark plugs after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the user manual. Refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. Spark Plug Replacement Steps: Open the hood, lift the engine's plastic cover, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing, check for external debris like leaves or dust and ensure they are thoroughly cleaned. 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 high-voltage ignition wires in the firing order, then secure the cover.

What Causes Smoke and a Burning Smell in a Car?

Car smoke and a burning smell can be caused by the following reasons: Clogged air conditioning intake: This prevents hot air from being blown out, leading to heat buildup that can melt plastic components. The solution is to first check if the intake is clear, then test the airflow from the vents by hand, and listen for any unusual noises from the air conditioning unit. Short circuit causes: Poor-quality or missing separators allow active material from the plates to pass through, causing virtual or direct contact between the positive and negative plates; conductive objects falling into the battery can connect the positive and negative plates; expansion and shedding of active material from the plates, with excessive accumulation of shed material, can cause the lower or side edges of the plates to come into contact with the deposits, resulting in a connection between the positive and negative plates.

What does U-shaped driving mean?

U-shaped driving refers to the driving method of entering the highway from the same station, making a U-turn in the middle, and then exiting from the same station. Highway positioning: Highways are a type of road classified by technical grade, with a higher level than first-class, second-class, third-class, fourth-class, and substandard roads. Highways intersect with national or provincial roads in the hierarchical classification of the road network, meaning highways are part of national or provincial roads in the road network. Precautions for highway driving: When driving normally on a highway, vehicles in the same lane must maintain a sufficient safe distance based on driving speed, weather, and road conditions. Under normal circumstances, when the speed is 100km/h, the safe distance should be more than 100m; when the speed is below 100km/h, the safe distance can be appropriately reduced, but the minimum distance should not be less than 50m.

Will the Reversing Camera Recover After Getting Water Inside?

If the camera gets water inside, it indicates a quality issue with the camera; drive the car to the place where the camera was installed and request a replacement. Below is relevant information about reversing cameras: 1. Introduction to Reversing Cameras: Also known as parking assist systems, reversing visual systems, or vehicle monitoring systems. English name: vehicle-backup-camera. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Advantages of Reversing Cameras: Installation is simple. Generally, a standard single-output reversing camera only requires connecting the positive power wire to the positive terminal of the car's reversing light power and the negative power wire to the negative terminal of the reversing light or to ground (GND). Wiring can be easily understood based on the vehicle model, and the camera can be installed by drilling a hole in a convenient location.

Will Making a U-Turn at a Crosswalk Always Be Captured by Cameras?

If there are electronic cameras, it will be captured as making a U-turn on a crosswalk is a traffic violation. According to Article 49 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China,' this offense incurs a penalty of 3 demerit points and a fine of 200 yuan. The regulation states: Motor vehicles are not allowed to make U-turns at locations with signs or markings prohibiting U-turns or left turns, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other hazardous road sections. Definition of yielding to pedestrians at crosswalks: Pedestrians walking on the right side of the crosswalk without reaching the centerline of the road. Vehicles on the left lane should slow down and proceed only when safe to allow pedestrians to cross. Pedestrians waiting outside the boundary line between motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and proceed when safe. If pedestrians cross the boundary line between lanes, vehicles failing to stop and yield are committing a violation and should be penalized. When pedestrians enter the motorized lane via the crosswalk, vehicles in adjacent lanes must slow down and proceed when safe. Failing to stop and yield is a violation. Pedestrians waiting at the centerline without entering the vehicle lane. Vehicles failing to stop and yield are committing a violation. Pedestrians crossing the centerline into the vehicle lane. Failing to stop and yield is a violation. If the road is divided by a green belt, vehicles must slow down and proceed when safe when pedestrians are waiting in the central area. Permissible U-turn scenarios: If there is a clear U-turn sign at the intersection, U-turns are allowed. If there is a U-turn signal, follow its indication. Without a signal, U-turns can be made if they do not obstruct other vehicles or pedestrians. Intersections without explicit 'No U-turn' or 'No Left Turn' signs allow U-turns. 'No explicit prohibition' means no 'No U-turn,' 'No Left Turn,' or solid centerline signs. Yellow grid lines also permit U-turns: Yellow grid lines indicate no-stopping zones at intersections prone to congestion. While stopping is prohibited, U-turns are allowed unless a central barrier exists. Intersections with U-turn signals: Follow the signal—green means U-turn is permitted. If 'No Left Turn' and 'U-turn Allowed' signs coexist: U-turns are permitted, but left turns are not. 'No U-turn' is not the same as 'No Left Turn.' Precautions when making U-turns: Check road markings—solid lines prohibit U-turns under any circumstances. Proceed to find a suitable location. If there's a 'No Left Turn' sign, U-turns are also prohibited, as they involve a left turn. U-turns must be made from the innermost left-turn lane. The second left-turn lane does not permit U-turns. Always yield to oncoming traffic before making a U-turn. Failing to do so makes you liable for any accidents. Near intersections, lane arrows guide vehicle movement. The leftmost lane may not always be for left turns.

Is there a reward for capturing illegal use of emergency lanes?

Capturing illegal use of emergency lanes is rewarded. To encourage reporting, cash rewards will be given once the reported traffic violations are verified. The reporting requirements state that for a single violation, more than 3 images should be captured, with the pictures ideally reflecting the entire process of the illegal act. Emergency lanes are primarily marked on urban ring roads, expressways, and highways, designated for vehicles handling emergencies such as engineering rescue, firefighting, medical aid, or police officers performing urgent official duties. Any private vehicles are prohibited from entering or stopping in these lanes for any reason. If encountering an unavoidable issue like a vehicle breakdown, the car should be parked in the emergency stopping area with hazard warning lights activated. A warning sign should be placed 150 meters behind the vehicle, and all other occupants must move to a safe area. If necessary, promptly call the highway emergency number for assistance.
