What are the functions of the engine lubrication system?

The functions of the engine lubrication system are as follows: 1. Reduce friction resistance: The lubricating oil forms an oil film between moving parts to reduce friction resistance and power loss, and minimize wear of components. 2. Prevent excessive part temperature: The cooling effect utilizes the fluidity of the oil to carry away some of the heat from engine parts, preventing them from overheating and burning out. 3. Cleaning effect: The circulating oil carries away metal particles worn off during engine operation, dust inhaled from the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts that could increase wear. 4. Sealing effect: The viscosity of the oil allows it to adhere to the surfaces of moving parts, improving the sealing effect and reducing air leakage. 5. Anti-rust effect: The lubricating oil film adheres to metal surfaces, isolating air and water, thereby providing anti-rust and anti-corrosion protection.

Is the BYD Song Pro fuel consumption high?

BYD Song Pro's fuel consumption is at the upper-middle level among its peers. Here is some relevant information about BYD: 1. Brand History: BYD Company Limited was founded in 1995, starting with a team of just over 20 people. By 2003, it had grown into the world's second-largest rechargeable battery manufacturer and established BYD Auto in the same year. Starting as a battery manufacturer, BYD was essentially an 'outsider' when it came to making cars. However, leveraging its strong reputation for 'independent intellectual property rights' and the acquisition of Qinchuan Auto, BYD gained a first-mover advantage over other newcomers. 2. Brand Introduction: BYD Auto adheres to a development path of independent R&D, independent production, and independent branding, committed to creating truly affordable and high-quality vehicles for the people. The product designs not only incorporate advanced international trends but also align with the aesthetic values of Chinese culture.

Can a New Car Be Restored to Its Original Condition After a Collision?

New cars cannot be restored to their exact original condition after a collision; they can only be repaired to a state where the appearance shows no obvious differences from the original. However, there will still be some differences in reality. Even if original factory parts are used, factors like technical and manual workmanship can lead to variations. After a collision, the most noticeable issues on a new car are paint scratches and dents, which require bodywork and repainting to restore the car's surface. The deformed parts of the metal body are repaired through bodywork and repainting, allowing the distorted metal surface to return to its original shape. Even after bodywork correction, there may still be some imperfections that cannot be fully remedied by bodywork alone. Even replacing parts with new ones may not achieve perfection. To achieve a more flawless and precise restoration, sculpting techniques are sometimes employed to address these imperfections.

Is Coasting in Neutral Good?

Coasting in neutral is not advisable. It not only fails to achieve fuel savings but also causes significant wear to components such as the clutch and gears. More importantly, coasting in neutral poses considerable safety risks. When the gearshift is placed in neutral for coasting, the drive wheels lose their driving force, and the power connection between the engine and the drive wheels is severed. The car can only move forward by its own inertia. In the event of an emergency requiring braking, the entire braking force must be provided solely by the braking system. This demands that the brakes supply a substantial amount of force in a very short time, yet the braking system's capacity is limited. Consequently, this will inevitably affect braking performance, at least by extending the stopping distance.

What Causes the Smell of Gasoline Inside the Car?

Fine cracks or damage in the fuel supply lines; 3. Gaps at the connection between the fuel pipe and the fuel tank, where loose clamps can cause the smell; 4. The carbon canister is filled with gasoline. Methods to remove the gasoline smell from the car include: 1. After closing the windows, select the car air conditioning cooling mode and use the internal circulation mode; 2. Place activated charcoal bags or fragrance bags inside the car to absorb the gasoline smell; 3. Use lemon or grapefruit peels inside the car to absorb the odor; 4.

What to Do If the Inspection Validity Period of the Vehicle License Has Expired?

The solution for an expired vehicle license inspection validity period is to receive 3 penalty points or renew the vehicle license. Below are the relevant details: 1. Precautions: If a vehicle fails to undergo the annual inspection on time, does not purchase compulsory traffic insurance as required, or fails to carry the vehicle license and driving license, the traffic police department will impound the vehicle in accordance with the "Road Traffic Safety Law." Insurance companies may refuse to compensate for accidents involving vehicles with overdue annual inspections. 2. Inspection Mark: Vehicles eligible for the 6-year exemption from inspection must apply for an inspection mark from the traffic police department every 2 years within the specified time frame. For vehicles with an annual inspection cycle of less than one year, they must undergo an on-site inspection within three months before the expiration of the inspection validity period.
