What does the maximum torque of a vehicle mean?

Maximum torque refers to the twisting force generated by the engine crankshaft. For vehicles with the same transmission ratio, greater torque means more power. Below are specific details about torque: 1. Torque is the average rotational force output from the crankshaft during engine operation, commonly referred to as the engine's 'rotational power.' It is a crucial parameter of engine performance. The greater the torque, the more 'power' the engine can deliver, resulting in faster changes in crankshaft speed and better vehicle climbing ability, initial acceleration, and overall acceleration performance. 2. Maximum torque typically occurs within the engine's mid to low-speed range. As the speed increases, torque tends to decrease. The unit of torque is Newton-meters (N·m) or kilogram-meters (Kg·m). Torque affects the vehicle's power during acceleration, including its initial take-off. Theoretically, higher torque leads to faster initial acceleration and a shorter time from 0 to top speed. If a vehicle has high horsepower but low torque, acceleration will be sluggish, making the driver feel strained.

How to Distinguish Between a New Car and a Stock Car?

Methods to distinguish between a new car and a stock car are as follows: 1. Check the vehicle production nameplate: Every car is affixed with a nameplate before leaving the factory. This nameplate contains not only information such as the vehicle model but also the manufacturing date of the vehicle. If the date on the nameplate is within 6 months of the purchase date, it is a new car; otherwise, it is a stock car. 2. Look at the production date of the window glass: On the car's front windshield, there is usually the production date of the glass. Based on this date, you can determine the approximate time frame when the glass was produced and whether the glass has been replaced, helping to distinguish between a new car and a stock car. 3. Check the Vehicle Identification Number (VIN): The VIN is a unique code. By examining the VIN, you can determine the car's production date. Specifically, the tenth digit represents the vehicle's production date. The length of time between the production date and the purchase date can help identify whether it is a new car or a stock car.

How Long Can You Drive After the Car Alerts for an Oil Change?

When the car alerts for an oil change, it can typically be driven for about 500 kilometers. Below are specific details regarding oil change alerts: 1. Generally, mineral oil needs to be changed within 5,000 kilometers, and should not exceed 6,000 kilometers at most. Semi-synthetic oil can extend the oil change interval to 7,500 kilometers, while full synthetic oil can extend it to 10,000 kilometers. Depending on different driving environments and habits, the interval can be appropriately adjusted. 2. When the oil warning light comes on, the first step is to open the engine compartment and check if the oil has been completely used up. If it has, you should purchase oil from the nearest auto parts store as soon as possible and add it temporarily. Continuing to drive without oil can cause engine components to rub against each other and become damaged due to the lack of lubrication. Of course, if the oil level is just at the minimum mark, it is generally safe to drive to the nearest 4S shop.

What to Do When the Car Air Conditioning is Not Cooling?

Reasons and solutions for car air conditioning not cooling are as follows: 1. Dirty air filter. If the filter is too dirty, it not only causes more impurities to be sucked into the car, which is harmful to health, but also blocks the air filter, reducing the cooling effect of the air conditioning. It is recommended to replace the air filter every 10,000 kilometers to ensure both the efficiency of the air conditioning and the health of passengers. 2. Insufficient or leaking refrigerant. Refrigerant, also known as Freon, is essential for cooling. If the refrigerant is low or insufficient, the cooling effect will decline or even stop. This can be easily fixed by refilling the refrigerant at a repair shop. If the air conditioning stops cooling again within a few months after refilling (normally, refrigerant should be refilled every 2-3 years), it may indicate a leak in the system, requiring professional repair. 3. Worn or loose belt. If you hear a 'squeaking' noise when turning on the air conditioning, the issue might be a loose compressor belt. Tightening the belt can solve the problem. Belts, made of rubber, have a limited lifespan and need replacement if they are too old. 4. Dirty condenser. If the condenser is not cleaned regularly, dirt and debris can cover it, preventing it from dissipating heat properly, which is another reason for the air conditioning not cooling.

How to Prevent Car Tire Blowouts?

Methods to prevent car tire blowouts are as follows: 1. Regularly check tire pressure. Changes in tire pressure are related to temperature variations, and cars are more prone to blowouts in colder weather. 2. Never use expired tires. Generally, the service life of a tire is about 2-3 years or 60,000 kilometers. Tires that exceed their service life or are severely worn should be replaced promptly. Therefore, pay close attention to the condition of your car's tires and replace them immediately if any issues arise. 3. Do not use damaged tires. Damaged tires refer to those with obvious holes in the sidewalls. Since drivers often travel on complex roads, punctures are hard to avoid. If a tire has obvious damage and continues to be used, a blowout may occur within a few kilometers. Therefore, develop the habit of regularly checking your tires for punctures, scratches, etc., and repair or replace them immediately if any are found. If stones are found in the tire treads, remove them promptly. 4. Avoid high-speed driving. When driving at high speeds, friction between the tires and the road increases, as does the load, raising the internal pressure of the tires, which can accelerate aging and even cause blowouts or damage. 5. Prevent overloading. When overloaded, tire pressure increases, making them more prone to deformation under pressure. To withstand such high pressure, the internal pressure of the tires also rises. Additionally, increased contact area can accelerate shoulder wear, especially when going uphill, making blowouts more likely. Therefore, it is best to avoid overloading while driving.

How to Renew a C1 Driver's License After 6 Years?

Driver's license renewal can be processed up to 90 days before the expiration date. The required documents for renewal include ID card, driver's license, medical examination certificate, photos, etc. Below are the steps for renewal: 1. Fill out the "Motor Vehicle Driver's License Application Form" and submit the physical condition certificate issued by a county-level or military medical institution at or above the regimental level. 2. Within 90 days before the driver's license expires, apply for renewal at the vehicle management office where the license was originally issued. When applying for renewal, prepare the original and photocopy of your ID card, driver's license. Any driver's license processing center has doctors stationed by "county-level or above medical institutions" who can conduct on-site medical examinations and fill out the "Motor Vehicle Driver's Physical Condition Certificate". 3. Bring three recent color front-facing half-inch photos with a white background, where the head occupies two-thirds of the photo length.
