Can Installing Running Boards Pass the Annual Vehicle Inspection?

Installing running boards is generally not allowed to pass the annual vehicle inspection, with specific requirements varying depending on different vehicle models. Below is relevant information about installing running boards: Functions of installing running boards: Some SUVs with relatively high chassis install running boards for easier entry and exit. After installation, it becomes more convenient to clean the vehicle body. Those who wash their cars themselves are well aware that it's difficult to clean the roof area without running boards. Regulations for installing running boards: Determined according to the content of the "Announcement on Road Motor Vehicle Manufacturers and Products" for specific vehicle models. You can inquire about the vehicle model announcement at the vehicle management office's license plate selection hall. If the announcement includes side running boards, they can be installed directly. If not, installation requires approval and registration modification from the vehicle management office.

How much can you exceed the speed limit?

Exceeding the speed limit in a speed-restricted zone is considered speeding. It is advisable to avoid speeding whenever possible. Below is relevant information: 1. On roads with a speed limit below 50 km/h: Exceeding the speed limit by more than 10% but less than 20% will result in a fine; exceeding by more than 20% but less than 50% will result in a fine; exceeding by more than 50% but less than 70% will result in a fine; exceeding by 70% or more will result in a fine. 2. On roads with a speed limit between 50 km/h and 80 km/h: Exceeding the speed limit by more than 10% but less than 20% will result in a fine; exceeding by more than 20% but less than 50% will result in a fine; exceeding by more than 50% but less than 70% will result in a fine; exceeding by 70% or more will result in a fine.

What is the difference between 21-inch tires and 20-inch tires?

20-inch wheels and 21-inch wheels differ in the following aspects: 1. Size difference: 21-inch wheels are larger compared to 20-inch wheels. 2. Aspect ratio difference: Generally, the larger the car tire size, the lower its aspect ratio. Tires with lower aspect ratios perform better in reflecting road conditions and providing lateral support during driving, while tires with higher aspect ratios offer better comfort but are relatively weaker in road feedback and lateral support. 3. Visual difference: Larger tire sizes naturally provide a stronger visual impact, making the car appear more imposing, while smaller tire sizes may slightly diminish the overall presence. These two different wheel sizes reflect different aspect ratios, meaning the tire thickness varies when viewed from the side. 4. Driving experience difference: 20-inch tires have thicker sidewalls, offering better cushioning on bumpy roads. In contrast, 21-inch tires provide more responsive handling at high speeds, but the road feel is stronger on uneven surfaces with weaker cushioning. In the event of a tire blowout, due to the larger diameter of 21-inch rims, the body tilts less, reducing the likelihood of sudden directional changes.

Are the Drainage Outlets of New Cars Opened?

New cars' drainage outlets are not opened and need to be opened manually. Here is the relevant information: 1. Precautions: When cleaning hidden hoses such as those for the sunroof, avoid using hard objects like iron wires to unclog them, as these objects may cause the hoses to break or detach. Compared to other components in the car, the drainage holes, which are simple in principle and seemingly insignificant, are often overlooked. However, these small drainage holes can frequently cause significant trouble during vehicle use. You can routinely inspect and address these minor issues yourself. 2. Drainage Outlets: Apart from the sunroof drainage holes connected to hoses, the drainage outlets in areas like doors and front/rear taillights generally drain directly through the drainage channels inside the doors.

Where is the MG6 engine produced?

The engine of the MG6 is independently developed by the BYD Group and is a domestically produced engine. The engine model used in the MG6 is the 15C4E, with a maximum horsepower of 181 HP, a maximum power output of 133 kW, a maximum power speed of 5600 rpm, and a peak torque of 285 N·m. For daily maintenance of the MG6 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB_CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry 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 particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, 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 Causes Fluctuating Idle Speed in New Cars?

Possible causes include oil accumulation in the throttle body and carbon buildup in the throttle, or a dirty intake tract. Here is relevant information: 1. Cleaning interval: It is generally recommended to clean the throttle body every 20,000 to 40,000 kilometers. However, this is only a reference value, and the specific cleaning interval should be based on factors such as the air quality of the driving environment, the type of engine oil used, the frequency of air filter replacement, and driving habits. 2. Unstable idle speed: If you notice insufficient engine air intake, unstable idle speed, sudden deceleration when releasing the throttle, reduced power, difficulty starting, or increased fuel consumption, it may also indicate that the throttle body needs cleaning.
