How to Check the Speed Rating on Car Tires?

Tire speed ratings are typically indicated by letters and numbers on the sidewall of the tire. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving, ensuring a comfortable ride and smooth operation. Car tires provide excellent traction between the wheels and the road, enhancing the vehicle's acceleration, braking, and off-road capabilities, while also supporting the car's weight. Structurally, tires can be categorized into radial tires and bias-ply tires; based on tread patterns, they can be divided into ribbed tread tires, transverse tread tires, mixed tread tires, and off-road tread tires.

What does highway ETC refer to?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. Highways are equipped with one or more ETC lanes. ETC charging method: Through dedicated short-range microwave communication between the on-board RFID tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the system uses networked technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through bridge toll stations without stopping to pay tolls. Banks install this type of ETC express card with a post-payment system. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle license. The photocopy of the driver's license should include the page with the most recent annual inspection stamp. Bank account card application form, which is used to bind the ETC card. After obtaining the card, you can go to the designated bank branch to receive and install the ETC on-board device for free, with no charges during the process. Applicants must be between 18 and 60 years old and own a personal vehicle. Documents required for company vehicles: Letter of introduction from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle license; vehicle that needs to apply for ETC. Precautions for ETC installation: Do not obstruct the view; it is best to install it behind the interior rearview mirror. Many car models have a large rearward angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Install it behind the right side of the interior rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not place it where the solar panel might be easily blocked. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If removed arbitrarily, the anti-removal lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable, requiring a visit to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.

What is the working principle of the fuel pump control circuit?

The working principle of the fuel pump control circuit is: 1. ECU-controlled fuel pump circuit; 2. Switch-controlled fuel pump circuit; 3. Speed-controlled fuel pump circuit. The fuel pump is a professional term in the automotive parts industry and is one of the basic components of the fuel injection system in electronic fuel injection vehicles, located inside the vehicle's fuel tank. The function of the fuel pump is to draw fuel from the fuel tank, pressurize it, and deliver it to the fuel supply line, working in conjunction with the fuel pressure regulator to establish a certain fuel pressure. The fuel pump consists of an electric motor, a pressure limiter, and a check valve, with the electric motor actually operating within the fuel inside the pump housing.

How long does it take to charge a completely dead car battery before it can be used?

It takes 20 to 24 hours to charge a completely dead car battery before it can be used. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'car battery' refers to a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. The plates of a standard lead-acid battery are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid, with the main advantage being stable voltage. Dry-charged batteries are characterized by their negative plates having a high capacity for storing electricity. Maintenance-free batteries, due to their structural advantages, consume very little electrolyte and generally do not require the addition of distilled water during their lifespan. They also feature resistance to vibration, high temperatures, compact size, and low self-discharge.
