Why Does a Car Shake at Low RPM?

Car shaking at low RPM can be attributed to the following reasons: 1. Dynamic Imbalance: A car's wheel is an assembly consisting of a tire and a rim. However, due to manufacturing variances, the mass distribution of this assembly may not be perfectly uniform. When the wheel rotates at high speeds, it can lead to dynamic imbalance, resulting in wheel shaking and steering wheel vibration during driving. 2. Hydraulic Power Unit Failing to Achieve Balance During Operation: The slow oil discharge rate (small discharge volume) from the large chamber of the cylinder causes the single-rod double-acting piston cylinder to move slower when the small chamber is supplied with oil compared to when the large chamber is supplied.

Can I Register a Car in a Different Location from Where I Purchased It?

Yes, you can purchase a car in one location and register it locally as long as you have the purchase invoice and the vehicle's certificate of conformity. Here are some considerations for registering a car purchased in a different location: 1. Is it worth buying a car in a different location: Travel and accommodation expenses can add up significantly when purchasing a car from another location. Therefore, before making the purchase, carefully consider whether it's truly worth traveling that far to buy a car. 2. Always buy from an authorized 4S store and verify if they support out-of-town purchases: When picking up the car, inspect it thoroughly, as some dealers might take advantage of out-of-town buyers by offering inventory or problematic vehicles. 3. Drive cautiously: Since the car is in its break-in period, drive carefully on the way back, ensuring the engine RPM doesn't get too high, and avoid sudden acceleration or braking.

What Does Comprehensive Range Mean?

Electric vehicles have two range values, one called the comprehensive range and the other called the constant-speed range (also known as the maximum range). These two range values are derived from different testing conditions. The comprehensive range is tested under conditions that more closely resemble everyday driving environments. Factors affecting the range of an electric vehicle: 1. Charging equipment: The quality of the charging equipment will affect the energy replenishment and output of the electric vehicle's battery, thereby impacting the range. 2. Tire pressure: Similar to gasoline-powered cars, low tire pressure increases rolling resistance and lateral steering resistance, causing the vehicle's battery to deplete quickly and reducing the range. 3. Overloading: Just like with gasoline-powered cars, overloading an electric vehicle undoubtedly increases its weight, requiring more battery output and accelerating energy consumption, inevitably leading to a reduced range. It is recommended to follow the law and avoid overloading. 4. Sudden stops and starts: Sudden stops or starts mean activating the motor in a very short time and consuming more electrical energy, which can also shorten the motor's lifespan. It is recommended that after starting an electric vehicle, it should be driven at a steady, slow speed for a distance before accelerating. Electric vehicles also need a warm-up period. While driving, maintaining a steady speed helps keep the battery in a stable working state, ensuring optimal range.

What are the reasons why the steering wheel cannot automatically return to center?

Here are the reasons why the steering wheel cannot automatically return to center: 1. Poor lubrication between the kingpin and bushing: After prolonged use, severe wear can lead to excessive clearance. At this point, the front wheel camber angle may disappear or turn into negative camber. When the front wheels tilt inward, the axis of the front wheels and the kingpin become nearly parallel. This increases the resistance arm during steering, preventing the kingpin inclination angle from functioning effectively. 2. Damage to the chassis or deformation of the suspension causing tire misalignment on one side: If the steering wheel cannot return to center at all when turned to one side, the problem is more serious. In this case, merely performing a wheel alignment is insufficient. When this occurs, 80% of the time the vehicle has experienced a significant collision. Therefore, a comprehensive inspection and repair of the vehicle is necessary to prevent further issues or even accidents during subsequent driving.

Can out-of-town license plates operate as Didi drivers locally?

Vehicles with out-of-town license plates cannot operate as Didi drivers locally. The Didi platform has currently closed the application portal for non-local vehicles. To apply, the vehicle must have a local license plate and meet the latest local motor vehicle emission standards, whether it is a personal vehicle or a taxi. Here is additional information: 1. Didi has strict requirements regarding the age of the vehicle and the driving history of the applicant. The vehicle must be less than eight years old. The applicant must not have any poor driving records, major traffic accidents, or traffic violation consultation records. 2. As for when the application portal for out-of-town vehicles will reopen, further notice from the transportation department is required.

What to Do If You Don't Want a Newly Purchased Car Anymore?

If you've paid taxes, you'll need to apply for a tax refund. If the car has already been registered, you can only sell it as a used car. 1. Specific circumstances: If you've just received the car and haven't completed the registration procedures, you can apply for a refund or negotiate with the salesperson to deduct some of the deposit. If you've paid in full, there's a 99% chance they won't agree to a refund unless there are issues with the car that prevent registration or other problems. 2. Special cases: If the procedures haven't been completed, try to find excuses, such as insufficient funds, not meeting mortgage conditions, inability to secure a loan, current inability to complete procedures, lost ID card, etc. The key is to proactively discuss the matter with the car dealership.

What does SUV crossover mean?

SUV crossover is explained as follows: Crossover, also abbreviated as Crossover in English, originates from sedan-style SUVs and gradually evolves into any cross-combination of sedans, SUVs, MPVs, and pickup trucks. It combines the comfort and stylish appearance of sedans, the handling of SUVs, and the flexible space arrangement of MPVs, along with the excellent off-road capability and safety of SUVs. In terms of space, it is much larger than traditional sedans. Additional information: 1. Characteristics of crossover vehicles: The most notable feature of a crossover is that it cannot be classified into any single car category. It does not belong to sedans, SUVs, or MPVs but incorporates the advantages of all these vehicle types. Its perfect body proportions, refined and luxurious interior, excellent handling, and elegant exterior make it stand out among its peers. Crossover vehicles highlight the comfort, sportiness, practicality, luxury, and versatility pursued by the new generation of cars. The 'Enjoy, Drive, Safety' crossover concept proposed by the Chrysler Group has become the standard for measuring the essence of modern crossover vehicles. 2. Common crossover models: BMW X6, Dongfeng Fengshen H30 Cross, Subaru Outback, Suzuki SX4 Hatchback, Nissan Qashqai, Chery Tiggo 3, Riich X1, Changan CX20, Great Wall C20R, Weilin V5, Kia Soul, Great Wall Coolbear, Honda Crosstour, etc.
