Is It Normal to Use 20 Wheel Weights for Dynamic Balancing?

What Causes Body Resonance and Shaking at 120 km/h?

The causes of body resonance and shaking at 120 km/h are as follows: 1. Brake-induced vibration: This is a relatively common issue caused by warped brake discs. When the braking surface of the disc develops noticeable wave-like patterns (uneven high and low spots), the brake pads will move unevenly during braking, resulting in vibration. The best solution is to replace both the brake pads and discs simultaneously, rather than replacing just one component. This prevents the new brake disc from being worn down again due to issues with the old brake pads. 2. Driveshaft-induced resonance: This problem typically occurs in long-wheelbase or rear-wheel-drive vehicles. The driveshaft, which transmits power from the engine to the rear wheels, has balance weights on its surface. If these weights are missing or the driveshaft is damaged, it can cause the driveshaft to wobble, leading to resonance. Additional Information: 1. Different vehicle models use tires with varying aspect ratios (the ratio of the tire's sidewall height to its width). High-aspect-ratio tires have longer sidewalls, which can absorb and filter out more vibrations but provide poorer road feedback and weaker lateral support. The sidewalls deform more significantly, reducing stability during crosswinds or sharp turns and increasing the "floaty" sensation. Low-aspect-ratio tires have shorter sidewalls, offering better anti-roll performance, less sidewall deformation, and more precise road feedback. While comfort may be reduced, handling improves, and the "floaty" feeling is minimized. 2. High-speed stability can also be affected by tire design. Low-aspect-ratio tires enhance control and reduce the sensation of floating, though at the cost of some comfort.

What is the fuel consumption of the Jetta VS7?

The fuel consumption of the Jetta VS7 is 7.14-9.14L/100km. The currently available Jetta VS7 models include the 2022 Black Edition 1.4T Automatic Honor Pro, Automatic Enjoy Pro; 1.4T Manual Entry Pro, 1.4T Automatic Entry Pro, Honor Pro, Enjoy Pro, Panda Edition 1.4T Automatic Enjoy Pro, and Automatic Honor Pro, totaling 8 models. The official NEDC combined fuel consumption is slightly lower than the actual fuel consumption, ranging from 6.4-6.8L/100km. Among vehicles in the same class, the Changan CS75 has an NEDC combined fuel consumption of 6.2-6.5L/100km, the Haoyue has 7.8-8.1L/100km, the Dongfeng Fengshen AX7 has 6.6-7.7L/100km, the Venucia T70 has 7.2-7.3L/100km, and the Jetour X90 has 7.6-8.1L/100km. The fuel consumption of a car is directly influenced by five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Details are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at a red light can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements typically produce more power, requiring more gasoline to burn and perform work. Heavier cars also have higher fuel consumption due to the greater driving torque needed. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance, leading to higher fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance, resulting in higher fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, in low temperatures, the engine's computer controls higher idle speeds to warm up the engine, further increasing fuel consumption.

What to Do When All Driving License Points Are Deducted?

If all points on your driving license are deducted, you should retake the subject one test. Below are the specific situations when all driving license points are deducted: 1. Retaking the test: For those holding a C-class license. Owners with a C-class license will have their license temporarily suspended and need to retake the subject one test. They can only drive again after passing the test. Driving during this period is considered unlicensed driving. For C-class license holders, if all 12 points are deducted during the probationary period, their probationary driving qualification for the permitted vehicle type will be revoked. 2. Direct downgrade: For those holding A or B-class licenses. Owners with A or B-class licenses will have their license directly downgraded if all 12 points are deducted. If all 12 points are deducted during the probationary period, their probationary driving qualification for the permitted vehicle type will be revoked. If the revoked driving qualification is not for the highest permitted vehicle type, their driving qualification for the highest permitted vehicle type will also be revoked.

How Many Days Does It Take to Get the License Plate After a Used Car Transfer?

You can obtain the new license plate 7 days after the used car transfer. Below is some information about license plates: 1. Definition: A license plate, commonly known as a car plate, is a panel hung at the front and rear of a vehicle. It is typically made of aluminum, sheet metal, plastic, or paper, displaying the vehicle's registration number and the relevant information of the registration region. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their primary purpose is to identify the vehicle's region of registration. Additionally, the vehicle owner and registration details can be traced based on the license plate.
