ETC does not need to be powered. There are two power supply methods for ETC devices: 1. Solar power supply: During the day when there is sunlight, the ETC device has solar panels that can convert solar energy into light energy for automatic charging. Solar power supply is the more commonly used power supply method and does not require manual charging; 2. Battery power supply: Normally, the ETC battery can last for 5 years. ETC is an electronic toll collection system that does not require stopping. The ETC dedicated lane is for vehicles equipped with ETC on-board units, using electronic toll collection methods. The ETC non-stop toll collection system is a more advanced road and bridge toll collection method. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, and using computer networking technology for backend settlement processing with the bank, the purpose of vehicles passing through road and bridge toll stations without stopping to pay tolls is achieved.

Where is the Lincoln car brand from?

Lincoln is an American brand, a luxury vehicle under the renowned American automobile company Ford. Here is more information about Lincoln: 1. Lincoln was founded in 1917 by Henry Leland, and the brand is named after U.S. President Abraham Lincoln. 2. Since 1939, starting with President Franklin D. Roosevelt, Lincoln vehicles have been chosen as presidential cars by the White House due to their outstanding performance, elegant styling, and unparalleled comfort. The most famous model is the parade car used by President Kennedy. 3. As a premium automotive brand, Lincoln currently offers only five models in China: the Lincoln MKZ and Continental in the sedan segment, and the Lincoln MKC, MKX, and Navigator in the SUV segment. 4. Lincoln's sales in China have been growing rapidly. However, in 2018, Lincoln encountered a setback. Data showed that Lincoln's cumulative sales in China for the first quarter of 2018 reached 12,710 units, a 10% year-on-year increase. In comparison, Audi sold 154,270 units (up 41.9%), and Cadillac sold 55,079 units (up 39.7%). In the luxury car market, Lincoln's sales and growth rate were nearly at the bottom. 5. In April 2018, Lincoln issued two recall notices within a week due to steering wheel and automatic transmission issues, recalling a total of 17,959 Lincoln MKZ vehicles. Data shows that from 2015 to 2018, Lincoln issued nine recalls in total. While the frequency is not extremely high, it is certainly not low in China's automotive industry, raising concerns among domestic consumers about Lincoln's quality standards.

Is the GTR four-wheel drive?

Nissan GTR is equipped with a full-time four-wheel drive system. Here is some relevant information about the Nissan GTR: 1. The Nissan GTR series uses a 3.8-liter twin-turbocharged V6 engine, which delivers 555 horsepower and a maximum torque of 632 Nm. This engine can output maximum power at 6,800 rpm and reach peak torque between 3,300 and 5,800 rpm. The engine features a continuous variable valve timing control system and utilizes an aluminum alloy cylinder head and block. 2. The Nissan GTR employs a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear. The multi-link independent suspension is an evolution of the double-wishbone design, where the two wishbones are replaced with individual links, making it a more complex version of the double-wishbone suspension.

What Causes the Vehicle to Cross the Line During Curve Driving?

Curve Driving Crossing the Line Specific Causes and Solutions Are as Follows: 1. When turning, the driver fails to check reference points and steer in time, missing the right timing, causing the car to lean too far to the right and cross the line. 2. When the car is about to exit the S-curve, the driver hastily straightens the steering wheel, leading to the left side of the vehicle crossing the line. 3. Lack of car sense, failing to correctly judge the vehicle's movement trend, resulting in crossing the line. Solutions: 1. Before entering the curve, position the vehicle as close as possible to the right curve, then gradually turn the steering wheel to the left. Note: When turning, do not only observe the front wheels' path but also monitor the rear wheels' trajectory through the rearview mirror. 2. Once the front wheels have exited the curve range, turn the steering wheel half a turn to the right; otherwise, the rear wheels may cross the line.

What to Do If There Are No Seat Belts in the Back Row of the Car?

If the rear seats of a vehicle do not have seat belts, they must be installed. The functions of seat belts are explained in detail below: 1. The primary role of seat belts is to ensure the safety of passengers and drivers. In the event of an accident or emergency braking, seat belts effectively restrain occupants in their seats, preventing forward impact and reducing injuries. 2. Seat belts mainly serve as a buffer to absorb the energy generated during a collision, mitigating the force of inertia. According to relevant data, wearing a seat belt reduces the fatality rate by 57% in frontal collisions and by 80% in rollover accidents. Seat belts are often referred to as life-saving belts. 3. Seat belts should be fastened whenever the vehicle is in motion, regardless of whether it is a passenger bus or a family car, and whether sitting in the front or back seats.

How Often Should Car Air Conditioning Compressor Oil Be Replaced?

Car air conditioning compressor oil replacement intervals should be determined based on the quality of the compressor and the frequency of air conditioning use. Under normal usage conditions, it is reasonable to replace car air conditioning compressor oil once a year. Compressor Oil: Compressor oil serves as a sealing medium for the compressor, ensuring safe operation while reducing friction and energy consumption. It possesses excellent performance characteristics, forming an oil film on the compressor surface to provide lubrication and protection. Compressor oils can be divided into two categories: piston/rotary compressor oils and refrigeration compressor oils. Piston and rotary compressor oils operate at higher temperatures. For most compressors, the temperature of air or gas after each stage of compression typically exceeds 170-180°C, though some high-thermal-intensity piston compressors may reach outlet temperatures over 220°C. To ensure safe compressor operation, extend oil change intervals, maintain clean pneumatic systems, and reduce friction and transmission energy consumption, piston and rotary compressor oils should have good thermal stability to prevent carbon deposits, along with excellent anti-corrosion, anti-emulsification, and anti-foaming properties. Compressor Oil Replacement Method: When replacing refrigeration oil in rotary compressors, first seal the compressor's low-pressure pipe and drain the refrigeration oil. Then connect the compound pressure gauge manifold valve to the compressor's high-pressure gas pipe, with one end of the high-pressure pipe connected to a vacuum pump and the low-pressure valve hose inserted into a measuring cup. Start the vacuum pump to create a vacuum inside the compressor, then close the high-pressure valve and open the low-pressure valve. The refrigeration oil in the measuring cup will be drawn into the compressor. When an appropriate amount of oil has been added, close the low-pressure valve to stop the oil intake.

What Causes Poor Seat Belt Retraction?

Poor seat belt retraction is due to lack of lubrication in the seat belt reel shaft. Below are the specific functions of car seat belts: 1. Protecting passenger safety: Car seat belts can protect passengers' safety, especially on highways where rear passengers need to wear seat belts. A seat belt buckle is a device that can be installed in the car's seat belt socket, preventing the seat belt alarm from sounding when the driver does not buckle up. 2. Ensuring driving safety: The seat belt is the only guarantee of the driver's safety while driving. Even when driving at relatively low speeds, in the event of a collision or emergency braking, although the generated inertial force is relatively small, it is still enough to prevent drivers and passengers from controlling their bodies, causing them to collide with hard components such as the steering wheel and windshield, resulting in physical injuries.
