How to Lower High Idle Speed?

What is the purpose of the dotted line on the rearview mirror?

The dotted line is the dividing line of a dual-curvature rearview mirror, which helps reduce the driver's misjudgment of the distance of vehicles behind and allows observation of both closer and farther positions on the side of the vehicle. The smaller section to the right of the dotted line has a magnifying effect, while the larger section to the left is a standard mirror surface. The reflection angles differ on either side of the dotted line, which means that when changing lanes to the left, the field of view becomes significantly smaller, creating a larger blind spot. The small area of the dual-curvature rearview mirror may also feature a small indicator, which serves as a "side blind spot warning system." When there is a potential collision risk on the side of the vehicle, this indicator will flash to alert the driver. If the body of a vehicle behind has entered the danger zone to the left of the dotted line on the rearview mirror, it indicates that the following vehicle is very close, and lane-changing should be avoided at this time. If the left side of the following vehicle's body is close to the boundary between the safe zone and the danger zone, the driver should remain vigilant, but turning with signals is still safe at this stage. If the following vehicle is in the safe zone, located in the center of the rearview mirror, it means the distance between the two vehicles is about 15-20 meters, and normal lane-changing operations can be performed. Functions of the dotted-line rearview mirror: A rearview mirror with a dotted line is called a dual-curvature rearview mirror, divided into two main sections by the dotted line. The dotted line is located at the outer third of the mirror, with the inner section being the normal reflection zone, also known as the standard rearview mirror area. This area provides a nearly 1:1 reflection with minimal distortion. The outer section has a higher curvature, offering a wider field of view, which helps drivers better adjust their vehicle position. For example, during reversing, the wider curvature allows for a broader view of the reversing area. The entire dual-curvature rearview mirror acts like a small convex mirror, expanding the driver's field of vision. Due to its compact size, the dual-curvature rearview mirror helps reduce wind resistance and improve fuel efficiency. It also includes an alarm system that alerts the driver when there is a potential side collision risk, prompting them to take evasive action. Most vehicles also feature rearview mirror heating. In special weather conditions, activating this function prevents fogging, ensuring clear visibility. During heavy rain, applying a rain repellent to the mirror can be helpful. Rain repellent forms a thin film on the glass surface, allowing water droplets to slide off quickly. This product can also be used on the windshield. Care should be taken to avoid scratching the rearview mirror, as its plastic housing is difficult to repaint. When parking on the roadside, folding the mirrors is recommended.

Is ETC Installation Mandatory for Vehicle Inspection?

Annual vehicle inspection can be conducted without ETC as it is not mandatory. ETC (Electronic Toll Collection) is merely a fast-pass payment method at highway toll stations designed to alleviate pressure on manual toll collection. According to State Council regulations, vehicles without ETC in 2020 would not enjoy toll discounts, and in the future, only one manual lane will remain at highway toll stations where drivers must pay tolls manually. Therefore, ETC has no direct correlation with vehicle inspection. Vehicle Inspection Items: Exterior Inspection: Bring the exterior inspection form to the designated station. First, verify relevant documents and check if the compulsory third-party insurance is valid. After document verification, the exterior inspection begins, focusing on checking lights for damage, ensuring the vehicle's appearance matches the original, verifying no modifications to the suspension, and inspecting the sunroof, tires, etc. Emission Testing: Queue up and wait for testing. Before testing, staff will conduct a preliminary check, mainly verifying if the engine number matches the vehicle registration certificate, briefly inspecting the exterior and condition, and then filling out the emission test form. During testing, an inspector drives the vehicle onto the testing line. New vehicles usually pass easily, and upon receiving a qualified emission test result, you can proceed to the payment window to collect the emission compliance label. If the vehicle fails, it must be adjusted at a repair shop and retested, requiring another testing fee. On-Line Testing: If the exterior inspection passes, queue up for on-line testing. The testing line checks brakes, headlights (high beam), chassis, etc., taking about 5-10 minutes. After completion, you receive a computer-printed form indicating pass ("0") or fail ("X") for items like brakes, lights, and horn. Typically, lights and brakes may fail, but testing centers have adjustment stations for these. Brake adjustments require retesting, while light adjustments only need a stamp after correction. Traffic Violation Check: At the query window, obtain and fill out the "Motor Vehicle Regular Inspection Registration Form" using your vehicle registration certificate. Submit the form to staff to check for violations. If no violations exist, the form will be stamped "Verified, Eligible for Inspection." If violations are found, handle them promptly using the violation notice. ETC Deduction Principle: Highways have one or more ETC lanes. Communication between the vehicle's onboard electronic tag (on the windshield) and the toll station's microwave antenna enables automatic toll deduction via computer-bank backend settlement, eliminating the need to stop at toll booths. This operates on a "pass first, deduct later" principle. Benefits of ETC Installation: Time-Saving: Eliminates waiting in queues. Green & Eco-Friendly: Reduces noise and emissions by avoiding idling at toll stations. Cost & Wear Reduction: Minimizes frequent starts and stops, lowering fuel consumption and wear. Efficiency Boost: ETC lanes can process vehicles 2-3 times faster than manual lanes, making ETC more advanced and efficient. Compared to license plate payment, ETC is more mature and advantageous. Policy Support: The State Council's "13th Five-Year Plan for Modern Integrated Transport System Development" aims for "50% ETC usage rate among road passenger vehicles by 2020" and promotes interoperability of transport cards in key city clusters. Future Potential: Beyond improving ETC convenience and passenger vehicle adoption, future plans include expanding ETC to trucks and integrating ETC with vehicle-to-vehicle communication and vehicle-infrastructure coordination for smart transport, offering comprehensive travel services and broader application scenarios.

How to Solve Fogging on the Inside of Car Windows?

Solutions for fogging on the inside of car windows: 1. Use the car's built-in air conditioning system: Turn on the fan and cooling function to remove the fog with cold air. Besides cooling, warm air can also be used to eliminate fog. 2. Open the windows to allow convection of cold and warm air: If the fog is not heavy and the outside temperature is not too cold, slightly open the windows on both sides to allow air convection inside the car, gradually balancing the interior temperature with the outside. 3. Use specialized anti-fog products: Before each use, spray evenly on the windows and wipe clean to form a transparent protective film on the glass, preventing fog formation.

Does Car Glass Need Waxing?

Car glass does not need waxing, as waxing is meant for maintaining the car paint, not the glass. The hazards of waxing car glass include: 1. The wiper blades cannot clean the glass properly on rainy days. 2. Residual wax from the wiper blades can accumulate on the rubber strips, causing them to harden and age over time. 3. At night, waxed windshields can become blurry, severely affecting driving safety. Methods to maintain car glass include: 1. Use specialized or suitable wiper blades and replace them in time. 2. Use automotive-specific glass cleaner. 3. Wipe off dust and debris from the wiper blades before use. 4. Use static cling film. 5. Cover the car with a car cover when parked.

What does the traffic violation code 1345 mean?

Automobile violation code 1345 refers to the act of violating prohibitive traffic markings, which includes driving over double yellow lines or parking in areas where parking is prohibited by marked lines. When a vehicle owner commits any of these acts, they will be issued a violation code 1345, resulting in a fine of 200 yuan and a deduction of 3 points from their driving license. The composition of traffic violation codes: 1. The first digit is the behavior classification code, indicating the category of the violation within the Road Traffic Law. 2. The second digit is the point deduction classification code, representing the category of the traffic violation in terms of point deduction. 3. The third and fourth digits are sequential codes, indicating the order of the violation within the same behavior classification.

Can the Throttle Body Be Left Unclean Indefinitely?

If the throttle body is never cleaned, it will affect the engine's air intake, leading to increased fuel consumption and reduced power. Therefore, it is recommended to clean the throttle body regularly. Over time, carbon deposits will accumulate on the throttle plate, but cleaning the throttle body is relatively simple and does not necessarily take much time. Below are the hazards of not cleaning the throttle body: 1. Prolonged neglect of cleaning can cause errors in the throttle opening angle. 2. It can also allow air with impurities to enter the engine combustion chamber. Both of these outcomes can lead to abnormal engine operation, mainly manifested as unstable idling, sudden throttle cut-off sensations while driving, reduced power, and in severe cases, even difficulty starting the engine and increased fuel consumption.
