What is the Principle of Run-Flat Tires?

Principle of run-flat tires: By thickening the tire sidewalls, they can still bear the weight of the car after a puncture, allowing the vehicle to continue driving for a certain distance. Here are the relevant details: 1. Run-flat tires: The technical name for run-flat tires is "Tire Pressure Monitoring System", with the English abbreviation RSC. The inflated tire sidewall is the main part supporting the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width), where the sidewalls are very "thick". 2. Precautions: The quality of tires is related to driving safety, so always pay attention to the condition of the tires before driving.

Can the ETC card be removed?

The ETC card can be removed, but the ETC device will not function without it. According to Article 9 of the "Rules for the Use of Non-Stop Rapid Passage Systems," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card for you. When the ETC card is inserted into the OBU device, a prompt sound will indicate that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations, so removing the card renders the ETC unusable. ETC is a non-stop electronic toll collection system, also known as an automatic road toll system. It is a specialized method for toll roads, commonly used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pass toll stations without stopping, all based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping; Reduced wear and tear: Saves costs by minimizing frequent starts and stops, lowering vehicle wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, key city clusters should achieve interoperability of transportation smart cards, and the proportion of vehicles equipped with ETC should significantly increase." It also set a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators for comprehensive transportation development during the 13th Five-Year Plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC adoption for trucks and explore deeper integration of the ETC system with smart transportation developments such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

How Long Can Tires Last?

Tires have a service life. When purchasing a car normally, 4S stores will kindly remind you that tires should be replaced every three years. However, it is common for many car owners to use them for five or six years without significant wear. Relevant details are as follows: 1. Composition of Tires: Tires are made from a combination of materials such as rubber, fabric, steel wires, carbon black, and other additives. After manufacturing, they are stored for 8 months to 2 years to allow the oils to fully release, giving the rubber molecules a stabilization period. Once the wear resistance meets the standard, they can be shipped out, allowing consumers to replace them immediately without waiting. 2. Aging Delay: The reason tires have a service life is that the core material, rubber, will age. Once rubber ages, it poses a serious threat to driving safety. However, with increasingly advanced formulations from tire manufacturers, the delay of rubber aging has become more effective. Therefore, it is not advisable to set an absolute time limit. Instead, it is necessary to observe the aging condition of the tire surface to determine whether replacement is needed.

Introduction to the Gears of MG5 Automatic Transmission?

The gear positions of the MG5 automatic transmission, from top to bottom, are P (Park), R (Reverse), N (Neutral), D (Drive), and S (Sport mode). Below is a related introduction to automatic transmission: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient the transmission is. 2. Manual Transmission Cars: They should shift gears at higher RPMs. The engine is designed to operate at higher RPMs, and the dynamic balance and rotational inertia of various components are also designed with high RPMs as the reference value. If the engine operates for a long time under non-standard conditions, the load and wear on internal components naturally increase, leading to frequent occurrences of shaking and knocking, which can also affect the engine's lifespan.
