Why can't solar panels be installed on car roofs?

The main reason for not installing solar panels on car roofs is that the electricity generated by the panels is insufficient to support vehicle operation, coupled with the influence of weather conditions, which makes manufacturers reluctant to install solar panels on cars. Under strong sunlight, the solar energy density at the Earth's surface is approximately 1kW per square meter, and the highest known photovoltaic conversion efficiency is currently 17.3%. This means that each square meter of solar panel can provide a maximum of about 170W of power. Here are some related points: 1. Installing solar panels on car roofs is not illegal, but it generally has little practical value because cars already have their own battery systems, which also provide DC power. 2. Under full sunlight, a monocrystalline silicon solar panel can generate about 1 kWh of electricity per square meter in around 10 hours. However, the roof area of most passenger cars is very small. Even if two square meters of solar panels could be installed, a full day of strong sunlight would only generate 1-2 kWh of electricity. 3. The battery capacity of new energy vehicles is at least 50 kWh or more. Even if 2 kWh could be charged per day, it would take nearly a month to fully charge the battery, whereas a fast-charging station can fully charge the battery in just over an hour.

What is the reason for the bulge in the middle of the rear seats of Volkswagen cars?

The reason for the bulge in the middle of the rear seats of Volkswagen cars is to distinguish between front-wheel drive and rear-wheel drive vehicles. Volkswagen models include: Volkswagen Lavida, Volkswagen Bora, Volkswagen Teramont, Volkswagen Lamando, Volkswagen Tacqua, etc. Taking the 2021 Volkswagen Lavida as an example, its body dimensions are: length 4670mm, width 1806mm, height 1474mm, with a wheelbase of 2688mm. The 2021 Volkswagen Lavida is equipped with a 1.4T turbocharged engine, with a maximum horsepower of 150ps, a maximum power of 110kw, and a maximum torque of 250nm, matched with a 7-speed dual-clutch transmission.

What Does It Mean When the Vehicle Body Crosses the Line?

Body crossing the line is a professional term for a foul during the second subject of the driving test. During reverse parking, if the body of the vehicle sweeps the line, it means the vehicle has entered the marked area of the garage, resulting in a deduction of 100 points, which leads to an immediate failure of the test. Therefore, extra attention should be paid during practice. Below are detailed explanations of related content: 1. Rules for crossing the line: According to the rules for the second subject of the motor vehicle driving test, stopping midway during the test, rolling back, not following voice prompts, or having the wheels or body of the vehicle cross the line will result in failure. 2. Reasons for crossing the line: The main reason for the wheels crossing the line is that the learner did not grasp the correct timing for steering. Apart from missing the right moment to steer, another possible reason is that the speed of steering does not match the speed of the vehicle.

What brand of engine is used in the Wuling Hongguang S3?

The Wuling Hongguang S3 engine is from the General Motors brand and is a domestically produced engine. The 1.5L version of the Wuling Hongguang S3 has an engine model L2B-P-TEC, with a maximum power of 73kW and a maximum torque of 140Nm. The 1.5T version has an engine model LJO, with a maximum power of 108kW and a maximum torque of 250Nm. For daily maintenance of the Wuling Hongguang S3 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What does it mean when the illumination distance of vehicle lights changes from near to far at night?

If you notice that the illumination distance of the lights changes from near to far while driving, it indicates that the vehicle is transitioning from a curved road to a straight path or from a steep downhill slope to a gentle curve. Below is a detailed explanation: 1. Explanation one: If you feel the vehicle speed automatically decreases and the engine sound becomes muffled, it means the vehicle is climbing an uphill slope or entering a difficult road section. 2. Explanation two: If you feel the vehicle speed automatically increases and the engine sound becomes lighter, it means the vehicle is descending a downhill slope. 3. Explanation three: If you notice that the illumination distance of the vehicle lights changes from far to near while driving, it indicates that the vehicle is approaching an uphill slope, a sharp curve, or the low point of a rolling road section.
