What is the ETC installed in the car?

The ETC machine installed in the car is called an OBU device. Once installed, activated, and a card is inserted, it can be used normally. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and certain sections of urban centers to alleviate traffic congestion. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual channels. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During free holiday periods, vehicles with ETC can still use highways, and no fees will be deducted when passing through ETC lanes. ETC Deduction Principles: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane, and by using computer networking technology for backend settlement with banks, the system achieves the purpose of collecting tolls without requiring vehicles to stop at toll stations. All this is 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, thus minimizing pollution. Cost-saving: Reduces wear and tear and fuel consumption by minimizing frequent starts and stops. Users also enjoy a 5% discount on toll fees. Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC systems more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development plan. Future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will include promoting ETC use for trucks and exploring deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of at least 10 meters to prevent automatic fee deduction for the wrong vehicle due to ETC device failure or absence. The ETC lane recognition speed is 20 km/h. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. If the detachment is not due to human error, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. Thick car windshields may cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.

Where is the car's tire pressure sensor located?

The installation position of a car's tire pressure sensor varies and can be categorized into built-in and external types. The built-in sensor is installed inside the tire, which is relatively more stable, while the external type involves adding a sensor outside the valve stem. The tire pressure monitoring sensor can accurately measure the temperature and pressure inside the tire. Tire pressure monitoring systems can be divided into two types: one is the indirect tire pressure monitoring system, which determines tire abnormalities through differences in tire rotation speed; the other is the direct tire pressure monitoring system, which involves installing four tire pressure monitoring sensors inside the tires.

Does turning a car screw clockwise tighten or loosen it?

Turning a car screw clockwise tightens it. Below is relevant information about car screws: Design reason: The majority of screws are designed with right-hand threads due to ergonomic principles. The speed direction relative to the rotation axis follows the right-hand rule, and over 90% of people are right-handed, making it more convenient for the majority. Additionally, right-hand threads are easier to manufacture, especially in large-thread turning processes. Important notes: Screws are critical fasteners in automobiles. The tightness and tightening sequence of these fasteners are extremely strict; otherwise, they may pose safety hazards.

Why Does a Car Shake?

Car shaking can be caused by: 1. Throttle malfunctions, such as throttle blockage or carbon buildup; 2. Excessive impurities in the intake tract, preventing the engine control unit from accurately regulating idle air intake; 3. Spark plug issues, like electrode erosion or damage; 4. Use of low-quality gasoline leading to fuel pump blockage or incomplete combustion of the air-fuel mixture in the cylinders; 5. Fuel injector problems, such as carbon buildup or clogging. Solutions for car shaking include: 1. Cleaning the fuel injectors and refueling at reputable gas stations; 2. Cleaning the intake tract; 3. Cleaning the throttle.

What Causes the Transmission Noise When Releasing the Throttle in a Jetta?

Jetta releasing the throttle transmission noise reasons are as follows: Bearing wear and damage: When the bearing is damaged, it cannot operate normally, resulting in abnormal noise and even damaging the transmission components, leading to further malfunctions. This can be caused by the wear of transmission components or the use of replacement parts with insufficient precision, such as excessive clearance between worn or new gears and the original gears. Poor lubrication: In this case, the corresponding lubricant should be replaced; otherwise, it will accelerate transmission wear and shorten its service life. Loose transmission bolts: Vibration during use can loosen the bolts, so regular inspections are necessary.
