The maximum speed shall not exceed 120 kilometers per hour, and the minimum speed shall not be less than 60 kilometers per hour. Precautions for driving on highways are as follows: Safety inspection: Check for potential safety hazards before getting in the car. Before driving on the highway, you should check whether the car has any potential safety hazards. Wear seat belts: Always wear seat belts on the highway, including the driver, front passenger and rear seats. Do not place unsecured objects in the car. Try to drive in one lane: Do not change lanes frequently on the highway, switching between the overtaking lane and the driving lane.

What to Do When the Car Door Freezes and Won't Lock?

Here are solutions for when the car door freezes and won't lock: 1. When the lock is frozen, use a hairdryer to heat it. The ice will melt quickly, allowing the door to close easily. 2. If a hairdryer isn't available, pour warm water over the lock several times. However, avoid using boiling water as it can severely damage the car's paint, doing more harm than good. 3. When there's significant ice buildup on the door, try using a card to scrape off the ice from the door frame. Remember to clean out any water and ice from the door seams to prevent rust and avoid refreezing. 4. If all four doors are frozen shut, first use the above method to close the driver's door, then turn on the heater and drive the car to a sunny spot. The doors should thaw shortly.

What Causes the Whitening of a Motorcycle Exhaust Pipe?

Motorcycle exhaust pipe whitening can be caused by water accumulation in the exhaust pipe or the use of substandard fuel. Below are the reasons and solutions for motorcycle exhaust pipe whitening: Water Accumulation in the Exhaust Pipe: Water produced during engine combustion and a small amount of accumulated water in the exhaust pipe. After the engine starts, whitening occurs due to temperature rise and evaporation. This is a normal phenomenon. As long as the engine oil does not decrease, it is not a case of excessive oil burning. Substandard Fuel: Substandard fuel, incomplete combustion, or excessive fuel burning can also lead to whitening of the motorcycle exhaust pipe. It is advisable to replace it with high-quality fuel.

Why does the motorcycle sound louder after replacing the cylinder?

Here are the reasons why the motorcycle sounds louder after replacing the cylinder: Piston not replaced: If the engine is burning oil, the cylinder, piston, piston rings, valves, and valve seals should all be replaced. If the piston is not replaced, the gap between the new piston rings and the cylinder will be smaller, causing the piston skirt to hit the cylinder when accelerating. This will make the motorcycle sound louder. All parts replaced: If all parts have been replaced, check the valve clearance. There may be a gap in the valves. Try running it for a few days to see if it improves. Difference in thermal expansion coefficients: The thermal expansion coefficients of the valve tappets and the camshaft may not match, meaning the difference is too large. This can also cause the motorcycle to sound louder.

Where is the motor vehicle QR code for vehicle owners?

Motor vehicle QR codes require vehicle owners to download the 12123 app to view their vehicle's QR code. This method protects citizens' privacy and prevents the leakage of personal information. Traffic police on duty can scan this QR code with professional equipment to access the vehicle's records, ensuring the uniqueness of the license plate while also enhancing efforts to combat counterfeit plates. As drivers of these vehicles, operating in dynamic spatial and temporal conditions, QR codes serve as a simple and practical information carrier. Authorities can monitor dynamic objects in real-time and track their movement trajectories, achieving networked and automated management processes. This also includes the management of vehicle information, inspections, safety, and verification. QR codes represent a new automatic identification and information carrier technology. In advanced foreign countries, this technology has been widely applied in fields such as national defense, customs, taxation, public security, and transportation for automatic information carrying, transmission, and anti-counterfeiting purposes.

What is an Engine Timing Cover?

Engine timing cover is the cover of the engine timing belt. Functions of the engine timing cover in automobiles: The timing belt serves as a link between the upper and lower parts, connecting the timing wheel on the engine cylinder head at the top and the crankshaft wheel at the bottom. The engine timing cover is the protective cover installed over the timing belt area, primarily providing dust prevention and protection. Precautions for installing an engine timing cover: Currently, when installing the engine timing cover, it is necessary to hold up the cover and align the mounting holes, which results in lower installation efficiency. Additionally, the noise generated by the timing belt during operation is easily transmitted, affecting the interior environment of the vehicle. Moreover, the timing belt may experience tooth jumping at high speeds, causing unstable transmission and impacting the vehicle's driving performance.
