Cars do not have lightning protection devices. Here are the details regarding lightning protection for cars: Reasons: The tires of a car have excellent insulation properties. If lightning strikes the car, the current cannot form a circuit to the ground, thus posing no harm to people or the vehicle. The tires may contain water or other conductive materials, but the car's body is made of metal while the tires are made of rubber, insulating it from the ground. Precautions: During thunderstorms, avoid leaving the vehicle. The vehicle acts as a relatively enclosed space with a metal body but insulated tires, making the entire vehicle an insulator. Additionally, it is important to close all windows and turn off the radio, as well as reduce speed while driving.

As an experienced driver who has been behind the wheel for many years, I must say that cars indeed don't have specialized lightning rods or any fancy devices like that. Think about it—car designs primarily focus on daily collisions and functionality, while lightning strikes are extremely rare occurrences. However, the metal parts of the car body act like a metal box. If struck by lightning, the current would travel along the outer shell without harming the people inside. This is called the Faraday cage effect. I've encountered thunderstorms in the southern regions, and when parked in an open area, the car actually felt much safer than being outside. But this isn't 100% foolproof—tires aren't fully insulated, and a lightning strike could cause a fire or damage the electronic systems. So, during thunderstorms, I always advise rolling up the windows, retracting the antenna, parking in a low-lying area, and waiting it out rather than risking a drive. Regularly checking tires and chassis grounding can also reduce risks. This kind of protection is more of a physical coincidence rather than a deliberately designed lightning protection system.

What Causes Steering Wheel Vibration in a BMW 3 Series After Falling into a Pothole?

BMW steering wheel vibration is mainly caused by tire dynamic balance issues. Four-wheel alignment problems: For example, increased or decreased toe-in; deformation of tie rods and steering tie rods, wear and looseness of various ball joints; uneven brake discs usually cause steering wheel vibration when braking at high speeds, requiring brake disc replacement; shock absorber failure. Half-shaft failure: This generally causes steering wheel vibration during acceleration; suspension failure or unbalanced support force; power steering belt too loose or too tight; during repairs, it is usually necessary to carefully inspect various parts connected to the vehicle's steering, such as steering wheel play, toe-in, front wheel alignment, wheel dynamic balance, suspension springs, and steering shock absorbers, based on different conditions.

Is the Original Car Paint Really That Important?

Automotive original factory paint is indeed very important. Here is more information about original car paint and aftermarket paint: 1. Original factory paint refers to the paint used when the car leaves the factory, applied to the entire frame using high-temperature paint, as there's no need to consider the heat resistance of other components. In contrast, aftermarket paint is only applied to parts of the body, requiring consideration of component heat resistance. The baking temperature for high-temperature paint is 190°C, while aftermarket paint is only 50-80°C, a significant difference. 2. Compared to original factory paint, repair paint lacks the passivation and phosphating processes and adds a filler (putty) process that is not beneficial for protection. Additionally, to achieve low-temperature curing, repair paint makes some sacrifices in final performance, far inferior to original factory paint in terms of hardness, adhesion, and aging resistance. 3. The materials used in original factory paint are also far superior to aftermarket paint. Original factory paint is precisely computer-mixed, not only vibrant and natural in color but also longer-lasting. Compared to aftermarket paint, it often results in completely different visual effects, sometimes with extremely noticeable color differences.

What are the dimensions of the Nissan Qashqai's crossmember?

The body dimensions of the Nissan Qashqai are 4401mm in length, 1837mm in width, and 1611mm in height, with a wheelbase of 2646mm. Model Introduction: The Nissan Qashqai is positioned as a compact SUV, which can be seen from the car's wheelbase. Engine: The new Nissan Qashqai is equipped with the all-new MR20DD naturally aspirated direct injection engine and a simulated 7-speed CVT transmission. Technically, it mainly adds direct injection and TwinVTC technology. The MR20DD engine with direct injection technology increases the fuel supply pressure from the traditional low pressure (about 5Bar) to over 100Bar through a high-pressure pump, directly injecting fuel into the cylinder. Fuel injection control is more flexible, and gasoline atomization is more thorough under high pressure. The 2.0-liter naturally aspirated engine with direct injection technology theoretically has higher fuel efficiency than the MR20DE engine used in the previous generation model.

What is the high temperature of the Skoda CSR engine?

The normal operating temperature of a car engine is between 80 and 90 degrees Celsius. Temperatures that are too high or too low are not ideal. Temperature: Temperature refers to the coolant temperature. After the engine warms up, it typically shows 80-90 degrees as normal. When the water level in the cooling tank is low, the temperature may rise, and at this point, water needs to be added. The car's temperature gauge usually has a scale from 60°C to 120°C or indicators marked Cold (C) - Hot (H). "C" is the first letter of the English word "cool," meaning cold. "H" is the first letter of the English word "hot," meaning heat. Engine: When the engine is running, the combustion of gasoline inside generates a significant amount of heat. Some of this heat is expelled through the exhaust, while some is transferred to the engine block. If the engine block temperature becomes too high, it can cause thermal expansion of components, leading to damage. Therefore, water is circulated to cool the engine.

Can You Drive with 1.4 Bar Tire Pressure?

Tire pressure of 1.4 bar is not safe to continue driving. Vehicles are equipped with tire pressure monitoring systems, which typically trigger an alarm when the tire pressure drops below 1.5 bar. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased tendency for the vehicle to drift, compromising driving safety; Excessive movement of tire components, causing abnormal heat due to over-compression; Reduced functionality of the tire's cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, resulting in bead damage and abnormal wear; Exponentially increased friction between the tire and the ground, causing a rapid rise in tire temperature, softening of the tire, and a sharp decrease in strength. High-speed driving under such conditions may lead to a blowout; Increased tire deformation, making the sidewalls prone to cracking, and generating flexing movements that cause excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear. Solutions for Insufficient Tire Pressure: If no visible damage is detected, simply inflate the tire to the normal pressure and reset the tire pressure system; If a puncture is found during inspection, promptly drive to a tire shop for repair and then reinflate the tire; If the tire pressure warning reappears after inflation without any visible puncture, it might be due to air leakage caused by a deformed rim. It is recommended to inspect and possibly replace the rim.
