Is it a problem if a piece of tire rubber comes off?

If a piece of tire rubber comes off, it may pose a safety hazard. If the sidewall of the tire is damaged, it is recommended to replace the tire, as the sidewall rubber is the weakest part and prone to blowouts from the damaged area. If the depth and width of the damage are less than 3 millimeters, the tire can be demoted to a spare. Additional information: 1. Impact of tire rubber loss: Tire thickness is designed to meet specific requirements. If a piece of tire rubber comes off, it can affect tire pressure, potentially leading to increased pressure issues in summer. It also poses a safety risk during high-speed driving. If a piece of tire rubber comes off, it is advisable to have it inspected at a repair shop to assess the extent of wear. 2. Importance of tires: Car tires are one of the most critical components of a vehicle, bearing the weight of the car and directly contacting the road surface. Together with the suspension system, they help absorb shocks during driving, ensuring a comfortable and smooth ride. Any damage to the tires should be taken seriously, as tires bear the entire weight of the vehicle, and a blowout can be extremely dangerous.

Can 48V Mild Hybrid Vehicles Get Green License Plates?

This type of vehicle cannot obtain a green license plate. Only pure electric vehicles and plug-in hybrid vehicles are eligible for green license plates. Green license plates are designated for new energy vehicles, specifically for pure electric vehicles and plug-in hybrid vehicles. The differences between plug-in hybrid vehicles and regular hybrid vehicles are as follows: 1. The most significant difference is that plug-in hybrid vehicles require charging, whereas regular hybrid vehicles do not. 2. Plug-in hybrid vehicles have larger batteries and more powerful motors, allowing for longer driving ranges in pure electric mode. Regarding regular hybrid vehicles: In most cases, the motor in a regular hybrid vehicle only serves to adjust speed and assist the engine. The motor in such vehicles typically operates only during startup or low-speed crawling. If you wish to use a green new energy license plate, you need to purchase either a pure electric vehicle or a plug-in hybrid vehicle.

Who is the inventor of the rotary engine?

The rotary engine is also known as the Miller cycle engine or the Wankel rotary engine. This engine was invented by German engineer Felix Wankel, who built upon previous research achievements and solved several key technical issues to successfully develop the first rotary engine. Here is more information about rotary engines: 1. Working principle of rotary engines: It uses the rotational motion of a triangular rotor to control compression and exhaust, which is fundamentally different from the linear motion of traditional piston reciprocating engines. The internal space of the cylinder is always divided into three working chambers, and these chambers move as the rotor rotates. The four processes of intake, compression, power, and exhaust are sequentially completed at different positions within the cycloidal cylinder. 2. Motion characteristics of rotary engines: The motion characteristics of rotary engines are: while the center of the triangular rotor revolves around the center of the output shaft, the triangular rotor itself also rotates around its own center. As the triangular rotor turns, the internal gear ring centered on the rotor meshes with a gear fixed on the cylinder (which does not rotate), with a gear ratio of 3:2. This motion relationship causes the trajectory of the rotor's apex (i.e., the shape of the cylinder wall) to resemble a figure "8". The triangular rotor divides the cylinder into three independent spaces, each sequentially completing intake, compression, power, and exhaust. For every full rotation of the rotor, the engine ignites and produces power three times. Due to this motion relationship, the output shaft rotates at three times the speed of the rotor's rotation, which is completely different from the 1:1 motion relationship between pistons and crankshafts in reciprocating engines.

What are the methods of installment car purchase?

Methods of installment car purchase are as follows: 1. 4S Store: Nowadays, many 4S stores can assist in handling car loans. By paying a certain service fee, you can easily obtain a loan. The threshold for auto financial loans is very low, requiring only a stable income source and repayment ability. You can choose your preferred car brand and inquire about specific installment loan options at the 4S store, selecting a suitable term based on your needs. 2. Credit Card: If your credit card limit is very high or the car loan amount is not substantial, using a credit card is also a good option. The down payment is generally between 30%-40% of the total car price, which is higher than other loan methods. The installment repayment period is limited, usually not exceeding 5 years, with annual interest rates determined by the car price. 3. Bank Loan: Many banks offer car loan services, and some models in collaboration with manufacturers may have special offers. If you plan to buy a car, it is advisable to check the official websites of major banks. Compared to the above two car loan methods, bank loans have lower interest rates, but the approval process is longer, and the procedures are more cumbersome. If your personal credit is poor or your income is unstable, you may also face rejection.

What are the advantages and disadvantages of applying a car paint protection film?

Car paint protection film has the following advantages and disadvantages: 1. Advantages of applying a car paint protection film: (1) The film perfectly protects the paint surface, eliminating the need to spend money on dealing with car scratches, especially for high-end cars, which can save a significant amount of money. (2) Vehicles with a paint protection film not only avoid spending money on scratches but also prevent the hassle of paint damage, oxidation, and other hazards during vehicle use. (3) Maintaining the appearance of the paint surface. Cars without a protection film will inevitably have color differences when repainted later, and the longer the time, the greater the color difference, significantly affecting the vehicle's aesthetics. With a protection film, there is no such worry. 2. Disadvantages of applying a car paint protection film: (1) As a cosmetic product for the car paint, once the film is damaged in a collision, it cannot be used and needs to be replaced, requiring the owner to pay for the replacement, which can be quite costly. (2) Car paint consists of three parts: primer, intermediate coat, and topcoat. While car paint is non-flammable, most paint protection films can be ignited. If fireworks accidentally come into contact with the car, it can easily cause the car to catch fire. (3) Car paint protection films are expensive, with a set costing over 5000. Moreover, the invisible film is a consumable with a service life of about three years. If it needs to be replaced due to surface wear, the cost is even higher.

What is the Difference Between Gross Vehicle Mass and Curb Weight?

Gross vehicle mass refers to the total weight of a vehicle when it is fully equipped and loaded with passengers (including the driver) or cargo as per regulations. Curb weight refers to the dry weight of the vehicle plus the weight of coolant, fuel (at least 90% of the tank capacity), spare wheel, and other onboard accessories. What is the difference between curb weight and gross vehicle mass? The specific descriptions are as follows: 1. Scope difference: Gross vehicle mass = curb weight + driver and passenger weight + luggage weight. The scope of gross vehicle mass is larger. 2. Meaning difference: The curb weight of a vehicle is closely related to its design level, manufacturing level, and industrialization level. On the other hand, gross vehicle mass simply represents the sum of various weights without any additional meaning.
