How does the car's ECO mode work?

The working principle of the car's ECO mode is: during vehicle operation, it comprehensively evaluates the automatic transmission gear position, engine speed, and transmission oil temperature to control the engine speed with appropriate gear selection. The onboard computer calculates the optimal fuel quantity to supply the engine for operation. ECO mode is the vehicle's energy-saving mode, but it cannot function under the following conditions: 1. When the vehicle speed exceeds 120 km/h, the energy-saving mode automatically deactivates; 2. During idle parking or when in N, P gear, or manual mode; 3. When overcoming certain resistance and requiring high torque output, the ECU prioritizes ensuring sufficient power to drive the vehicle.

High Beam or Low Beam on Highways?

High beam should be used on highways, but switch to low beam when the distance to the vehicle ahead is within 100 meters. Highway lighting selection: In normal weather conditions, fog lights should not be used, whether during the day or night. Additionally, when meeting oncoming traffic on roads without a median barrier, you should slow down at a distance of about 150m and switch from high beam to low beam. If the oncoming vehicle does not switch to low beam, the driver should slow down and use alternating high and low beams to signal the oncoming driver. If the oncoming driver still does not change the lights, simply continue driving in your own lane. Lighting operation methods: To operate the lights, first ensure the vehicle is in the ignition-on state. Headlights, width indicator lights, and other lights are controlled by the lighting control knob (or button) on the left side of the driver's seat. Turn signals are controlled by the lighting control lever on the left side of the steering wheel.

Where is the Best Place to Install ETC?

The optimal installation position for ETC in small cars is generally in the upper middle section of the front windshield, while for large vehicles like trucks and buses, it is recommended to install it in the lower middle section. The suitable installation height should be no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection seal. Additionally, a bank card under the owner's name for deducting highway tolls is required, and the owner must be between 18 and 60 years old. Here are some considerations for installing ETC: Do not obstruct the driver's view; it's best to install it behind the rearview mirror: Many car models have a steeply angled windshield, which can reduce the driver's field of vision. Installing ETC without considering this can increase blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a built-in solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the ETC device malfunctioning in the vehicle ahead, maintain a distance of at least 10 meters to prevent automatic toll deduction for the preceding vehicle. The ETC lane recognition speed is 20 km/h; driving too fast may result in failure to read the vehicle's device information and cause toll deduction failure. If using a debit card linked to ETC, insufficient balance will also lead to toll deduction failure.

What are the advantages and disadvantages of a dual-clutch transmission?

The advantages of a dual-clutch transmission are: 1. Due to more direct gear shifting and smaller power loss, fuel consumption can be reduced; 2. Instead of using a torque converter, two sets of clutches are employed, which work alternately to achieve seamless gear shifting. The disadvantages are: 1. The extensive use of electronic components increases the likelihood of malfunctions; 2. For small-displacement engines, there is insufficient torque at low speeds. In general vehicles, there are only manual and automatic transmissions. Manual transmissions often experience temporary power interruption during gear shifts, while automatic transmissions suffer from slow response times. The dual-clutch transmission combines the respective advantages of traditional manual and automatic transmissions.

What are the symptoms of a faulty thermostat?

The symptoms of a faulty thermostat are: 1. If the thermostat fails to open, the temperature gauge will show the coolant temperature in the high-temperature zone, but the radiator fan won't turn on, the engine temperature will be high, and it's prone to losing antifreeze; 2. If the thermostat fails to close, the coolant temperature will rise slowly, especially in winter where it may stay in the low-temperature zone for 10 to 20 minutes, and the idle speed will be high. A thermostat is an automatic temperature-regulating device, usually containing a temperature-sensitive component that opens or closes the flow of coolant through expansion or contraction. It automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the circulation range of the coolant to regulate the cooling system's heat dissipation capacity.

What is the actual fuel consumption of the Luxgen U7?

The actual fuel consumption of the Luxgen U7 ranges from 12 to 16 liters per 100 kilometers. A vehicle's fuel consumption is not only related to the engine displacement but also depends on factors such as the driver's habits, tire pressure, and road conditions. If the owner frequently drives in congested urban areas, the fuel consumption will be higher compared to driving on highways. The Luxgen U7 is an SUV under Dongfeng Yulon, featuring rounded and powerful European-inspired lines that create a mature and refined personalized style similar to imported European SUVs. Its body dimensions surpass those of its competitors in the same class, with a length of 4800mm, width of 1930mm, and height of 1760mm, along with a 2910mm wheelbase, making it fully comparable to luxury SUVs.

How to Handle Vehicle Scrapping Procedures?

Vehicle scrapping procedures are as follows: 1. The vehicle owner (individual or organization) submits a scrapping application; 2. The applicant brings the vehicle's license (or copy) and their ID card to the municipal metal recycling company to obtain the vehicle scrapping certificate; 3. The owner then uses this certificate along with the vehicle license and plates to complete deregistration at the local vehicle management office, and proceeds to cancel road maintenance fees and operational fees at the transportation bureau. For vehicles meeting national mandatory scrapping standards, the process includes: 1. Presenting documents at the dismantling facility; 2. Receiving the vehicle scrapping notice; 3. Delivering the vehicle to an authorized dismantling plant; 4. Photographing the disassembly of five major components; 5. Submitting dismantling photos for scrapping registration; 6. Applying for subsidies.
