Car scraping the chassis and feeling a loud noise is a problem of loose components. Here is some relevant information about loose components: 1. Some components in the engine compartment, such as the engine cover and intake pipe, may become loose. When the vehicle is in motion, these parts can collide with the compartment, causing noise. Tightening them can solve the issue. 2. If the screws used to secure the engine become loose, the engine may shake and produce abnormal noises. Simply tightening the screws can resolve this. 3. Over time, a car may accumulate a significant amount of carbon deposits, which can also cause the engine to sound louder. When the engine is running, carbon deposits can adhere to internal friction components, increasing friction and amplifying the noise.

What to Do If the Duplicate Copy of Driver's License Is Lost?

If the duplicate copy of your driver's license is lost, you can personally visit the local vehicle management office with your ID card, driver's license, and a one-inch color photo with a white background to apply for a replacement. Below is relevant information about driver's licenses: 1. The motor vehicle driver's license in China consists of the original driver's license and the duplicate copy. A driver's license without the duplicate copy is invalid, and similarly, a duplicate copy without the original driver's license is also invalid. 2. The function of the original is to record information such as the driver and the permitted vehicle types. It does not need to be changed when the recorded information remains unchanged, hence the original is laminated. If the recorded information changes, the license needs to be replaced. The main function of the duplicate copy is to record reminders, which can change at any time, so it is not laminated and needs to be kept properly.

What Causes Increased Engine Oil Consumption?

Increased engine oil consumption may be caused by the following reasons: 1. Piston ring wear or damage. When piston rings wear out, their elasticity weakens, reducing the pressure on the cylinder wall and diminishing their oil-scraping function. Additionally, wear between piston rings and ring grooves increases side clearance and back clearance, leading to more oil being drawn into the combustion chamber. This effect is magnified several times if the oil control ring is damaged. 2. Excessive clearance between the piston and cylinder wall. If the fit between the piston and cylinder wall becomes too loose or the cylinder wears into a tapered or oval shape, the piston rings, piston, and cylinder wall cannot seal properly. Splashed oil will then enter the combustion chamber through the gaps and burn, causing a significant increase in oil consumption. 3. Severe wear of the intake valve guide. During the intake stroke, engine oil can be drawn into the cylinder in large quantities through the gap between the valve stem and guide hole under the vacuum effect of the intake manifold, where it is burned. 4. Use of low-viscosity oil. Low-viscosity oil is more prone to being drawn into the combustion chamber, forms a thinner oil film that is easily burned, and also has a higher evaporation rate.

What is the fuel tank capacity of the Baojun 730 in liters?

The fuel tank capacity of the Baojun 730 is 52 liters, as officially announced. Owners who have purchased the Baojun 730 can also verify this information on the vehicle's specification sheet. The recommended fuel grade for the Baojun 730 is 92 octane, with a fuel consumption ranging from 6.8 to 7.6 liters per 100 kilometers. A full tank can cover a distance of approximately 684 to 765 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This occurs because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit, with additional space remaining from the safety limit to the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
