What does ETC vehicle mean?

ETC vehicles refer to vehicles equipped with ETC onboard units. ETC stands for Electronic Toll Collection in Chinese, which is currently the most advanced bridge and road toll collection method in the world. It utilizes dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. How ETC works: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, it uses computer networking technology to conduct background settlement processing with banks. This achieves the purpose of vehicles passing through highway or bridge toll stations without stopping while still being able to pay the tolls. Benefits of installing ETC: Saves time by eliminating the hassle of waiting in queues. Environmentally friendly as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions, thereby decreasing pollution. Reduces wear and saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users can also enjoy a 5% discount on toll fees. Improves efficiency - ETC lanes can theoretically increase vehicle passing efficiency by 2-3 times or more, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What to Do When the Engine's Air-Fuel Mixture is Too Lean?

An excessively lean air-fuel mixture is often caused by low fuel pump pressure. Dirty or clogged fuel injectors, or faults in the control circuit, can also lead to a lean mixture. Poor signals from the intake pressure sensor may result in fluctuations between rich and lean conditions. It's advisable to check the data stream to observe changes in injector pulse width and oxygen sensor voltage. Additionally, test-drive the vehicle to see if there's a noticeable lack of acceleration, combining diagnostic tool readings with driving conditions. The primary cause of a lean mixture is insufficient fuel injection, specifically: 1. Faulty intake sensors that inaccurately measure air intake, leading to inadequate fuel injection. 2. Excessive carbon buildup that absorbs injected fuel. 3. Failure of the oxygen sensor's closed-loop control. 4. Inaccurate detection of intake air volume.

What should you pay attention to when driving in the rain?

Precautions for driving in the rain are as follows: 1. Reduce overtaking: Due to the rain, the steering wheel becomes more sensitive and harder to control. It is best for drivers to stay within their designated lane and minimize lane changes. Avoid overtaking on narrow roads to prevent skidding. 2. Turn on the headlights: Driving with headlights on during rainy days is beneficial for safety, as visibility is poor. The lights make the vehicle more noticeable to others, reducing the likelihood of traffic accidents. 3. Drive slowly: Wet and slippery roads affect braking performance, especially for vehicles without electric power-assisted systems. High speeds can increase braking distance, potentially leading to rear-end collisions if braking is delayed. Sudden braking may also cause the vehicle to veer off course, and failing to slow down when turning can result in skidding or drifting. 4. Check the windshield wipers: In rainy conditions, overall visibility is poor, and rain hitting the windshield worsens it further. If the wipers are faulty, they cannot clear the water and mist from the windshield, significantly impacting driving safety. Therefore, drivers should check the wipers before heading out and confirm they are working properly before starting the vehicle.

What is the matching method for BMW headlight driver module?

BMW lighting module is located under the headlight, and the light operation matching can be performed after starting the vehicle. The following is a detailed introduction to the classification of BMW car lights: 1. Headlights, the combined headlights are located at the front of the car, mainly serving the purpose of lighting and signaling. The light emitted by the headlights can illuminate the road conditions in front of the car body, allowing the driver to drive safely at night. 2. Combined taillights, the combined taillights are located at the rear of the car, mainly serving the purpose of lighting and signaling. 3. Turn signals, used to indicate left or right turns to other road users. Regulations require them to be amber. 4. License plate lights, mainly used to illuminate the license plate, enabling people to identify the vehicle license plate at night.

How to Fix the Jerking When Accelerating a CNG Vehicle?

When a CNG vehicle experiences jerking, you can check the working condition of the pressure regulator. Here are the specific steps for adjusting the CNG pressure regulator: 1. Adjust the idle solenoid valve: First, keep the throttle opening unchanged, then manually adjust the idle solenoid valve and power valve to achieve the highest engine idle speed. 2. Adjust the idle screw: You can adjust the idle screw to maintain the engine at the lowest stable speed. After repeated adjustments, the vehicle's minimum idle speed under CNG conditions can be obtained, ensuring consistent idle speed between gas and fuel modes, resulting in smoother engine operation.

Can a car that uses 98 octane fuel use 95 octane fuel?

You can add 95 octane fuel after using 98 octane fuel, but it is not recommended to do so long-term. Please note the following: 1. Do not mix different octane ratings of gasoline. If you previously used 98 octane fuel, you should continue to use 98 octane fuel for the next refueling. 2. In special circumstances, adding 95 octane fuel once is not a major issue, but prolonged use can lead to engine knocking, increased carbon deposits, and higher fuel consumption. 3. Similarly, if a car owner has been using 95 octane fuel, adding 98 octane fuel once or twice will not have a significant impact, but long-term mixing is not advisable. 4. If a car owner wishes to switch gasoline octane ratings, it is best to wait until the fuel tank is nearly empty (when the fuel gauge light comes on) before refueling with the new octane rating, or to drain the remaining fuel before switching, rather than mixing the two directly.
