Car bumpers are made of plastic to absorb and cushion external impacts, thereby protecting the vehicle body, pedestrians, and passengers. Here are the details: Protection Principle of Plastic Bumpers: When a car collides at low speed, the plastic bumper's cushioning effect can protect the vehicle body to some extent. Additionally, due to the plastic bumper's ability to crumple, it also helps protect pedestrians in the event of a collision. Practical Significance of Plastic Bumpers: Using plastic bumpers benefits both car manufacturers and owners. For manufacturers, plastic bumpers are more cost-effective than metal ones. For owners, replacing plastic bumpers after a collision is more economical.

What is the oil filter model for the Baojun 310?

It uses Shanghai GM Wuling Total specialized engine oil, with a 5W30 grade specification. Below is relevant information about engine oil: 1. The internationally recognized classification is the SAE classification, where SAE stands for the Society of Automotive Engineers. 2. In the SAE classification, there are low-temperature viscosity grades such as SAE0W (W stands for winter), 5W, 10W, 15W, 20W, and 25W. The smaller the number, the better the performance in low temperatures. For example, 0W indicates good lubricity at -30°C; 5W represents -25°C; 15W stands for -15°C; 20W indicates -10°C; and 25W represents -5°C. Apart from low-temperature viscosity grades, there are also high-temperature viscosity grades like SAE20, 30, 40, 50, and 60. The larger the number, the higher the viscosity of the engine oil.

What are the symptoms of a faulty dual-clutch transmission valve body?

Transmission valve body failure symptoms include the vehicle not moving in reverse, dashboard warning lights illuminating, solenoid valve fault alerts, occasional failure to move in forward gears, and jerky gear shifts in forward gears. These are all signs of transmission issues. Below are specific details about transmissions: Mechanical Continuously Variable Transmission (CVT): The characteristic of a mechanical CVT is that the gear ratio is not a series of discrete steps but a continuous range of values, allowing better coordination between the vehicle's driving conditions and engine load. This maximizes engine potential, improves fuel economy, and provides seamless traction performance, significantly enhancing overall vehicle performance. Automated Manual Transmission (AMT): The AMT is an improvement over the traditional manual gear transmission, combining the advantages of both automatic (AT) and manual (MT) transmissions into an integrated electro-hydraulic automatic transmission. The AMT retains the automatic shifting benefits of hydraulic automatic transmissions while maintaining the high efficiency, low cost, simple structure, and ease of manufacturing of manual transmissions.

Does Frequent Vehicle Title Transfer Have Any Impact?

Frequent vehicle title transfers can have certain impacts. Here are the specific details: Excessive transfers may indicate poor vehicle condition: For instance, paint surface issues can be assessed by checking for paint marks on the car. Whether the car has been repainted doesn't necessarily indicate problems, but you can carefully examine the repainted areas to identify issues. Also, inspect the paint conditions on the mechanical hood, fenders, and A-pillars. If the transfers occur through normal transactions with sufficient time intervals, the impact on price won't be significant. However, if the intervals are short, it may raise suspicions about potential vehicle issues. Impact on vehicle value: The more times a vehicle's ownership is transferred, the more drivers it has had. Each person's car usage and maintenance habits differ. Some may continue regular maintenance at 4S shops, while others might go to local garages, and some owners might neglect maintenance altogether, resulting in lower vehicle value.

Will the insurance company compensate if the car is flooded in an underground garage?

After purchasing vehicle damage insurance, the insurance company can compensate for a car flooded in an underground garage. Here are the details: Prerequisite: The owner of the damaged vehicle must have a prerequisite when claiming compensation from the insurance company: they must have signed an "Automobile Insurance Contract" with the insurance company and have purchased vehicle damage insurance. This establishes a legal contractual relationship between the owner and the insurance company, allowing the owner to claim compensation. Important Notes: If the car is flooded in the garage, immediately report it to the insurance company and seek their assistance. Do not attempt to start the engine, as this can easily damage it. If the engine is damaged under such circumstances, the insurance company has the right to refuse compensation for the engine's damage if the owner has not purchased additional water-related damage insurance, only covering the body damage. However, if the owner has purchased vehicle damage insurance along with water-related damage insurance, full compensation will be provided.

What does the crank connecting rod mechanism mainly include?

The crank connecting rod mechanism mainly includes the cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner, and oil pan of the engine block group; the piston, piston rings, piston pin, and connecting rod of the piston connecting rod group; and the crankshaft, flywheel, torsional vibration damper, and balance shaft of the crankshaft flywheel group. The engine block serves as the installation foundation for all mechanisms and systems of the engine, accommodating all major components and accessories inside and outside, and bearing various loads. Therefore, the engine block must have sufficient strength and rigidity. Working principle of the crank connecting rod mechanism: During the power stroke, the piston is subjected to the expansion pressure generated by combustion gases, converting the linear motion of the piston into the rotational motion of the crankshaft through the connecting rod, thereby outputting power. Relying on the rotational inertia of the crankshaft and flywheel, the connecting rod drives the piston up and down to complete auxiliary strokes such as exhaust, intake, and compression, preparing for the next power stroke.
