Do Flood-Damaged Cars Have Many Issues After Repair?

After being repaired, various components of a flood-damaged car will be affected, and there will be relatively many issues post-repair. Here are some precautions regarding flood-damaged cars: Pay attention to the powertrain: If the car has been submerged, it can only undergo a complete overhaul. To determine whether the engine has been disassembled and overhauled, you can check the engine mount screws and other screws on the engine for signs of disassembly. For instance, the engine mount screws are marked with torque lines during factory assembly, and after disassembly, the old marks will no longer align. Level: Generally, flood-damaged cars are categorized into three levels: water-wading cars, partially submerged cars, and fully submerged cars. The extent of vehicle damage varies depending on the degree of submersion.

What are the vision standards for driver's license medical examinations?

For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tram driving licenses, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other driving license categories, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. For those with monocular vision impairment, the naked or corrected vision of the better eye must reach 5.0 or above on the logarithmic visual acuity chart, and the horizontal field of vision must reach 150 degrees. The following is an extended introduction: Those who cannot apply for a motor vehicle driver's license include individuals with organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, paralysis agitans, mental illness, dementia, and other neurological diseases that affect limb movement and hinder safe driving.

Why Won't a Gas-Powered Car Start?

Human operational reasons for a gas-powered car failing to start: dead battery, empty fuel tank, incorrect gear position. Below are detailed explanations: Empty fuel tank: The fuel gauge shows below the red line, naturally preventing the car from starting. Dead battery: This may be caused by prolonged headlight use without turning them off, leading to battery drain, or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit malfunctions. Checking for a dead battery is simple—just press the horn. Incorrect gear position: For automatic transmission cars, the gear must be in P (Park) or N (Neutral) to start. If left in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars also won't start if the clutch isn't depressed.

What lights to use when navigating sharp bends?

Use low beam headlights when navigating sharp bends. The reasons are as follows: Reason 1: During nighttime driving, visibility is poor, making it difficult to see the road ahead clearly. Therefore, it is essential to use low beams when turning at night. Reason 2: When passing through sharp bends or slopes at night, it is necessary to alternately switch between high and low beam headlights. Information about low beam headlights is as follows: Low beam headlights: Designed for close-range illumination, their primary design requirement is a wide coverage angle (160 degrees) with a short projection distance, and the focus cannot be adjusted. Projection distance: Although low beams typically illuminate about 30-40 meters ahead, they feature a very distinct cutoff line between light and dark areas.

What are the uses of zinc in new energy vehicles?

In the high-voltage connectors of new energy vehicles, some manufacturers use zinc alloy for their high-voltage connectors. Here is an extended introduction to this: Introduction to New Energy Vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. Classification of New Energy Vehicles: New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline and diesel.
