The reason cars are not afraid of lightning strikes is that the car's shell is close to a Faraday cage and can conduct electricity through wet tires. Car shell close to a Faraday cage: The car's shell is made of metal with excellent conductivity, which is very close to the conditions of a Faraday cage. Therefore, when driving in thunderstorm weather, even if the car is unfortunately struck by lightning, the electromagnetic environment inside the car is basically unaffected, allowing people to stay safely inside the vehicle. Can conduct electricity through wet tires: The lightning current will use rainwater to reach the axle position through the car's surface, and the wet tires will quickly conduct the current to the ground. Therefore, the interior of the car is an ideal lightning shelter outdoors.

What are the road traffic rules for motorcycles?

The road traffic rules for motorcycles are as follows: On roads with the same direction, the left lane is the fast lane, and the right lane is the slow lane. Motor vehicles driving in the fast lane should travel at the speed specified for the fast lane. Vehicles that cannot reach the specified speed of the fast lane should drive in the slow lane. Motorcycles should drive in the rightmost lane: on roads with traffic signs indicating speed limits, drive according to the indicated speed. When a motor vehicle in the slow lane overtakes the vehicle in front, it may temporarily use the fast lane. On roads with two or more motor vehicle lanes in the same direction, changing lanes should not affect the normal driving of motor vehicles in the related lanes.

What is the Difference Between Adaptive Cruise Control and Full-Speed Adaptive Cruise Control?

The differences between full-speed adaptive cruise control and adaptive cruise control are as follows: 1. Speed limitations differ: Full-speed adaptive cruise control can be used at any speed. Adaptive cruise control can only be used at speeds above 40 km/h or 60 km/h. 2. Nature differs: Full-speed adaptive cruise control does not require the driver to touch the accelerator or brake pedal during vehicle operation. Adaptive cruise control assists the driver in driving and alleviates fatigue. Adaptive cruise control technology is built on the foundation of active safety configurations, requiring radar, ultrasonic, and infrared sensors to detect obstacles, pedestrians, and vehicles ahead. It must include automatic braking functionality to ensure precise distance control.

Solution for P0480 Cooling Fan Control Circuit Malfunction?

P0480 trouble code indicates a malfunction in the fan control circuit. Here are the methods to clear the fault: 1. After troubleshooting the vehicle, it is necessary to clear the fault code: The fault code must be cleared strictly according to the specified fault code clearing procedure for the specific vehicle model. Under no circumstances should the negative battery cable be disconnected directly to clear the fault code. 2. Test the vehicle wiring and check the fan relay: If the low-speed fan control circuit still shows significant current consumption when grounded, or if no voltage is detected when the low-speed fan control circuit is not grounded, the trouble code will appear; if the low-speed fan does not rotate normally after the engine is warmed up, but continues to rotate after short-circuiting the relay, it is necessary to check whether the relay's pull-down or pull-up circuit is faulty.

How to Turn Off the Engine Start-Stop Function in Nissan Qashqai?

Nissan Qashqai's automatic start-stop function is enabled by default. Press the AUTO STOP OFF button to deactivate the engine auto start-stop feature. Here are some key details about the Qashqai: 1. The Qashqai is the first model designed by Nissan's European Design Center. Its name derives from an Iranian nomadic tribe living in desert regions, meaning 'urban nomad,' positioning it between compact SUVs and hatchbacks. 2. The Qashqai boasts a stylish and avant-garde exterior, a simple yet elegant interior, precise and comfortable handling, excellent fuel efficiency, and high safety standards. It is a true SUV built on an SUV chassis, offering superior comfort and agile driving. 3. Exterior-wise, the new Qashqai follows the design of its overseas counterpart, with Nissan's V-Motion design language evolving towards a younger aesthetic. The front grille is larger than the current model, featuring a honeycomb pattern. 4. Under the hood, the new Qashqai is powered by a 2.0L inline four-cylinder naturally aspirated engine, with a maximum power increase of 3KW compared to the current model. Its fuel consumption is just 6.0L per 100km, a 13% reduction from the previous version, and it complies with the China 6B emission standard. 5. The LED headlights have a sharp design, with more three-dimensional front-end styling and more complex air intake designs. The rear of the new Qashqai remains largely unchanged, with upgraded tail light assemblies featuring new internal structures and a redesigned rear bumper. The large black plastic panel paired with a two-tone silver skid plate adds a fresh touch.

Why does the car body shake violently when the AC is turned on?

The reason for the violent shaking of the car body when the AC is turned on is the increased load on the engine. The following are specific explanations: 1. The power output of each cylinder of the engine is uneven, and the variation between cycles of the same cylinder is relatively large: The lower the engine speed, the greater the variation. When the AC button is pressed, the vehicle's speed will increase. Observe whether the increase in speed is the same as before. If not, the throttle body needs to be checked. 2. If the increase in engine speed is consistent, the spark plugs and fuel injectors need to be inspected: Irregular variations in spark energy and fuel injection quantity cause variations between different cylinders and cycles of the same cylinder. It is necessary to check the burning condition of the spark plugs, whether the gaps are consistent, and the consistency of fuel injector flow, especially the consistency at low flow rates.

How Often Should Motul 7100 Engine Oil Be Changed?

Replace the engine oil thoroughly approximately every 5,500 kilometers driven, and clean the oil filter every 90 million kilometers driven. Only by regularly changing the engine oil and cleaning the filter can you avoid component wear and oil passage blockage. Motul 7100 is suitable for the latest high-power output engines, direct injection engines, and catalytic converters. It has high-efficiency lubrication capabilities, reducing internal engine friction. Notes on engine oil change: Match with the engine: Choose engine oil based on the engine's requirements. Do not use high-grade oil in lower-grade engines, nor low-grade oil in high-grade engines. Select oil that matches the engine. Advantages: Multi-grade oil should be chosen. Multi-grade oil has advantages such as economy, long service life, and high efficiency, providing better protection for the engine.
