What does 'Da Ben Che' mean?

Automobile Da Ben refers to the motor vehicle registration certificate. Vehicle registration certificate: The motor vehicle cost is the vehicle registration certificate. The motor vehicle registration certificate is the legal proof of vehicle ownership, kept by the vehicle owner and not carried with the vehicle. Subsequently, when handling any vehicle registration procedures such as transfer or change of ownership, the vehicle registration certificate must be presented, and relevant vehicle details will be recorded on it. It is equivalent to the 'ID card' of the vehicle. The vehicle registration certificate serves as a record and is not proof of vehicle ownership. As automobiles are movable property, the sales contract can serve as proof of vehicle transfer, indicating the change of ownership. Whoever controls the vehicle possesses the operational benefits of the vehicle. The motor vehicle registration certificate is the legal proof of vehicle ownership, kept by the vehicle owner and not carried with the vehicle. In other words, with this motor vehicle registration certificate, the owner can prove that the vehicle is their own, serving as a legal basis.

Why Does the Antifreeze Level Drop Quickly?

The main reasons for a rapid decrease in car antifreeze include leakage, poor circulation leading to fast consumption, or coolant entering the cylinders and being burned or leaking into the oil pan. If the rapid decrease is due to leakage, traces of leakage are usually visible at the leak points. The solution is to replace the radiator or tighten the screws at the overflow tank, water pump joint surface, and cooling system pipelines. If the issue is poor circulation, it's advisable to have a professional mechanic inspect the system. If the coolant is being burned in the cylinders or leaking into the oil pan, it's important to check whether the engine cylinder head gasket or intake manifold gasket is damaged. If damage is found, repairs or replacements are necessary. Method for Replacing Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with particular attention to the five-way hose. The five-way hose gets its name from having five connections to different parts of the car. Antifreeze flows through the five-way hose and is distributed to various parts of the vehicle to perform its function. If there's any leakage of antifreeze in this section, replace the hose or resecure the connections as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue adding water until it flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the hoses may have a faint pink tint. Keep adding clean water until the outflowing water runs clear. Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose to allow it to flow quickly into the radiator. Then, add another container of antifreeze to the reservoir until it's nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level may drop slightly as air is purged from the system. Top up the antifreeze to the "MAXT" mark on the reservoir.

Is the Motorcycle Air Filter Important?

Motorcycle air filter is important. Function of Motorcycle Air Filter: The motorcycle air filter plays a crucial role for the motorcycle, primarily filtering dust from the air to prevent unclean air from entering the cylinder and exacerbating wear. Precautions for Air Filters: Using low-cost filter paper to make the filter element, due to its large pore size, poor uniformity, and low filtration efficiency, cannot effectively remove harmful impurities from the engine, leading to early engine wear. Using low-quality adhesives in minimal amounts, which are neither oil-resistant nor firmly adhesive, causes short circuits at the bonding points of the filter element; or using staples to connect the seams of the filter element, which cannot be sealed, resulting in short circuits and allowing large amounts of harmful impurities to enter the engine, reducing its lifespan. Replacing oil-resistant rubber parts with ordinary rubber parts may cause internal sealing failure, leading to internal short circuits in the filter, resulting in early engine wear and reduced lifespan, or external sealing parts may expand and deform, causing the oil filter's outer sealing ring to be squeezed out, leading to significant oil leakage in a short time, causing engine bearing wear and seizure, resulting in severe damage. The welding points on the air filter housing are spot-welded instead of seam-welded, failing to ensure sealing and causing short circuits. The central tube material of the oil filter is thinner than required, lacking sufficient strength, and may collapse during use, causing the filter element to break and block the oil passage, leading to insufficient engine lubrication; or the reliability of the crimped edges is poor, causing them to separate during use, resulting in significant oil leakage in a short time, leading to bearing wear and seizure. Metal parts such as the filter element end caps, central tube, and housing are not treated for rust prevention, causing metal corrosion and generating impurities, turning the filter into a source of contamination. Even worse, some use cement instead of adhesive, which is even more harmful.

What to Do When a Car Exceeds 15 Years?

The legally stipulated service life of a car is fifteen years, but it does not mean that the car must be scrapped after fifteen years. The service life can be extended with timely annual inspections. The new regulations for the scrapping of household cars are as follows: New scrapping regulations based on mileage: The new regulations for the scrapping of household cars remove the stipulation on the service life of private cars and set the scrapping mileage limit for private cars at 600,000 kilometers. This method, which replaces the service life limit with a mileage limit, greatly improves the utilization rate of cars. New regulations abolish scrapping age limit: The scrapping age limit for household cars has been abolished. Under the new policy, private cars need to undergo two annual inspections per year starting from the 15th year after registration, and four regular inspections per year starting from the 21st year for cars older than 20 years. The annual inspections have strict regulations for older vehicles.
