Is it necessary to cancel ETC if not in use?

It is not mandatory to cancel, but it is recommended that car owners cancel it if they no longer use it. ETC is an electronic toll collection system, also known as an automatic road toll system, specifically designed for toll roads. It is commonly seen on highways, toll bridges or tunnels, and certain sections of city centers to alleviate urban traffic congestion. The impact of not canceling: According to the regulations of various banks and ETC management departments, a vehicle can only be bound to one ETC account. Therefore, if the original ETC is not canceled, a new ETC cannot be applied for. If the vehicle is sold to someone else without canceling the ETC and the device remains in the vehicle, the toll station will recognize the ETC device. As long as the original owner's bank card still has a balance, toll fees will continue to be deducted from the original owner's account. The principle of ETC toll deduction: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle's on-board 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 accounts with the bank in the background. This achieves the goal of vehicles not needing to stop at toll stations to pay road and bridge fees, all based on the principle of passing first and deducting fees later. Benefits of installing ETC: Saves time: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduces wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, reducing wear and fuel consumption; Improves efficiency: The efficiency of ETC lanes can theoretically increase 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, the interoperability of transportation cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will also be made to promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide car owners with comprehensive travel services, meaning more application scenarios will support ETC usage.

Are the Rear Axle and Transfer Case Parallel?

Rear axle and transfer case are not parallel. Reasons why rear axle and transfer case are not parallel: The transfer case and engine must be at the same height because if they are too low, it may cause grounding, hence they are positioned higher. The rear axle, being connected to the suspension and wheels, needs to absorb shocks on bumpy roads, so it is positioned lower. Introduction to the principle of transfer case: The transfer case is a device that distributes the engine's power to the front and rear axles. From this perspective, the transfer case is essentially a component in four-wheel-drive vehicles. With the development of four-wheel-drive technology, the transfer case has continuously evolved, forming various styles to match different four-wheel-drive vehicles with varying demands. The basic principles and functions also differ accordingly. Introduction to the principle of rear axle: The rear axle refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-axles, enabling differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels. In front-wheel-drive vehicles, the rear axle is merely a trailing axle, serving only a load-bearing function. If the front axle is not the drive axle, then the rear axle becomes the drive axle, in which case, in addition to bearing the load, it also serves driving, deceleration, and differential functions. For four-wheel-drive vehicles, a transfer case is usually installed in front of the rear axle. Rear axles are divided into solid axles and semi-axles. Solid axles are paired with non-independent suspensions, such as leaf spring suspensions, while semi-axles are paired with independent suspensions, such as MacPherson suspensions.

How to Solve Sticky Car Windows?

Solutions for sticky car windows: 1. Clean or replace the wiper: After prolonged use, the rubber guide channels of the car windows may accumulate dust or suffer from rubber aging, often causing the windows to rise slowly or stop at a certain position. This is mostly due to excessive dust and debris in the glass guide channels, increasing resistance. 2. Use a towel-wrapped chopstick: Simply insert a chopstick wrapped in a towel into the glass guide channel. Adjust the number of towel layers based on the channel's width to ensure an appropriate thickness. 3. Clean the guide channel: Move the towel-wrapped chopstick up and down forcefully within the channel to clean it, and repeatedly remove the towel to wash off the accumulated dirt until all debris is cleared.

What are the reasons for the vehicle body crossing the line during parallel parking?

The reasons for the vehicle body crossing the line during parallel parking are: steering the wheel too late, causing the vehicle to press against the line on the right and rear, returning the steering too early, and failing to correct the direction in time. Here are some precautions regarding parallel parking: 1. Maintain distance: Before parking, when the vehicle is close to the right side of the road, pay attention to maintaining a certain distance from non-motor vehicles and pedestrians to ensure safety. 2. Avoid reverse parking: Do not park in reverse to avoid affecting normally moving vehicles. 3. Observe the surroundings: After the vehicle is parked and before opening the door, observe the situation in front of and behind the vehicle first, confirm safety, and then open the door without obstructing the passage of other vehicles and pedestrians.

Will the Transmission of a Flooded Car Get Water Inside?

Whether the transmission of a flooded car gets water inside depends on the vehicle's condition. Relevant explanations about water entering the transmission of a flooded car are as follows: 1. Vehicle in motion: Generally, as long as the vehicle is still moving and the engine is not turned off, even if the transmission is submerged in water, it will not get water inside. Although the transmission has a vent hole, because the transmission is working, there is pressure inside the housing, preventing water from entering. 2. Vehicle stationary: When the vehicle is parked and the transmission is not working, if the housing is submerged in water, water can enter through the vent hole. In this case, the transmission must be inspected, and the transmission fluid must be replaced. If not replaced within 4 hours, even if repaired three to five days later at a repair shop, transmission failure may still occur after five months.

What Causes Uneven Airflow from Car Air Conditioning Vents?

If the airflow is weaker when using the external circulation mode but normal with internal circulation, it is likely due to a clogged cabin air filter. In this case, replacing the cabin air filter should resolve the issue. Internal Air Duct Flap Issue: If the airflow remains weak regardless of the circulation mode, it may indicate problems with the internal air duct flap or similar components. This situation is less common than the previous one. It is recommended to first inspect the cabin air filter. Replacing a dirty air filter that is obstructing airflow into the vehicle may solve the problem. How Car Air Conditioning Works: The car air conditioning refrigeration system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower motor. These components are connected through copper (or aluminum) pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system operates, the refrigerant circulates through this closed system in different states.
