How long does the ETC battery last?

Generally, an ETC device can last 2-3 months on a single charge. The ETC user manual does not specify how long a single charge lasts. For car owners who do not frequently use ETC, it is recommended to charge the ETC device every 3 months. For wired power-supplied ETC devices, if they are not used for a long time, it is advised to charge them once a month to avoid affecting the battery lifespan due to self-discharge. ETC stands for Electronic Toll Collection, which refers to the electronic toll system. To apply for ETC, the following documents are required: the owner's valid ID card and vehicle license (original and copies), and if the application is made by a proxy, the proxy's valid ID card is also needed. The copy of the vehicle license should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old and own the vehicle in their name. For company vehicles, the required documents include: A letter of introduction from the vehicle owner (with company seal); a copy of the organization code certificate or business license (with company seal); the original ID card of the proxy; the original vehicle license; and the vehicle for which ETC is to be installed. ETC works by communicating with microwave antennas in ETC lanes at toll stations via an onboard electronic tag installed on the vehicle's windshield. It uses computer networking technology to settle payments with banks in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls. Benefits of installing ETC: Time-saving: Avoids the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing start-stop cycles, and users can enjoy toll discounts; Efficiency improvement: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Which is better, V6 engine or inline-six?

There is no absolute superiority, as each has its own advantages and disadvantages. The inline-six cylinder engine offers strong power, simple layout, and high stability; the V6 engine provides better smoothness and comfort. Therefore, the choice can be made based on needs: if you prefer handling and power, choose the inline-six; if you prefer comfort, choose the V6. Here is the relevant introduction: 1. The inline-six cylinder engine is structurally simpler, with all cylinders arranged in a straight line, requiring only one cylinder head and one set of double overhead camshafts. 2. The V6 engine is most commonly arranged as two inline-three cylinders at a 60-degree angle, requiring two cylinder heads and two sets of camshafts.

What type of suspension does the BMW M5 Competition use?

The BMW M5 Competition features a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear. Here are the relevant details: 1. The BMW M5 Competition is equipped with a 4.4-liter twin-turbocharged V8 engine, which delivers a maximum power output of 460 kW and a maximum torque of 750 Nm. The engine reaches its peak power at 6,000 rpm and its maximum torque between 1,800 and 5,860 rpm. It is paired with an 8-speed automatic transmission. 2. The double-wishbone suspension can absorb more impacts, thereby improving the car's comfort and reducing brake dive and body roll. The multi-link suspension enhances the wheel's contact with the road, improving traction and the car's handling performance.

How Long Can Car Tires Be Stored Before They Become Unusable?

Newly produced tires require 8 to 12 months of storage before entering a stable period. Tires stored for more than 3 years should not be used. This time frame is calculated from the production date, not the purchase date. Generally, the production date is marked on the sidewall of the tire. Here is some relevant information: 1. Typically, the service life of a tire is around 5 years, meaning that the time from production to installation should not exceed 8 years. Generally, tires should be replaced every 5 years or after driving 60,000 to 80,000 kilometers. However, the actual replacement cycle depends on driving conditions, temperature, tire pressure, and driving habits, as tire wear varies under different circumstances. 2. If a tire is severely worn and the tread pattern becomes smooth, its grip and drainage performance will significantly decrease, compromising safety. This can lead to vehicle skidding, longer braking distances, and a higher risk of accidents. Regular checks, such as cross-rotating front and rear tires, testing tire pressure, and performing wheel balancing, are essential to ensure driving safety.

What should the RPM be at 70 km/h?

If the speed reaches 70 kilometers per hour, the highest gear should be engaged. Generally, the engine RPM at this speed is around 2000 revolutions per minute, and for some cars, it may even be lower than 2000 RPM. This is because the transmission has more gears. Here is some additional information: 1. When cruising at high speed, the highest forward gear should be engaged to reduce engine RPM and improve fuel economy. 2. Some automatic transmission cars have many gears. Generally, cars with more gears will have very low engine RPM when the highest gear is engaged, which is beneficial for fuel economy. 3. When overtaking, downshifting in advance will increase the engine RPM and wheel torque, allowing for quicker overtaking.

What should be paid attention to when replacing brake pads?

The following are the precautions when replacing brake pads: 1. When installing new brake pads, distinguish the inner and outer sides. The friction surface of the brake pads should face the brake disc to ensure proper fit between the disc and pads. Install the accessories properly and tighten the caliper body. Before tightening the caliper body, use a tool (or a special tool) to push the piston back to its original position to facilitate proper installation of the caliper. 2. If you need to replace the brake pads on a drum brake, it is recommended to go to a professional repair shop and have it done by professionals to avoid errors. 3. After installing the brake, the tire should be reset to its original position. 4. When installing the tire screws, tighten them diagonally, which helps protect the tire and brake hub. At the same time, check whether the wear on the tread and edges is normal. It is best to periodically swap the left and right wheels, as this will help extend the service life of the tires. Finally, the brake fluid should also be checked.
