Does idling with the AC on consume fuel?

Idling with the AC on does consume fuel. Here is relevant information about fuel consumption: 1. Reasons for high fuel consumption: Poor fuel line condition: Excessive carbon buildup causing fuel line blockage leads to increased fuel consumption. Brake abnormalities: Brake pads not retracting properly, keeping the vehicle in a constant braking state while driving. Spark plug issues: Generally, spark plugs need replacement after 20,000-30,000 kilometers of driving. 2. Methods to reduce fuel consumption: Correct bad driving habits, avoid using low-quality gasoline, clean engine carbon deposits, avoid sudden acceleration, clean the throttle valve, and reduce vehicle load. Removing unnecessary items from the trunk can reduce vehicle weight and improve fuel efficiency.

What to do if ETC was not scanned when exiting the highway after being scanned when entering?

If you used ETC when entering the highway but it wasn't scanned when exiting, the unpaid fee can be deducted together during your next toll station exit. If the toll station cannot resolve this issue, you need to bring your ID card, vehicle license, and OBU device to the local ETC service center for troubleshooting. 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 the toll station, the system uses computer networking technology to perform backend settlement processing with the bank. This allows vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees. Where ETC can be installed: For small vehicles like cars and minivans, the OBU device is installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, it's installed on the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; The installation angle N should be between 30º and 90º (the angle between the electronic tag surface and the horizontal plane).

How to Clean Adhesive Residue on a Car?

Adhesive residue on a car can be cleaned and removed using the following methods: 1. Soapy water solution: Ordinary soapy water is simple, convenient, and easy to use for cleaning tree sap. 2. Essential balm removal: Apply essential balm to the adhesive and scrub with a cotton swab. 3. Alcohol removal: Brush alcohol onto the adhesive on the glass; once dissolved, the residue on the car body can be peeled off. 4. Dishwashing liquid cleaning: Apply undiluted dishwashing liquid to the car body, let it soak for a while, then rinse with water for effective cleaning. 5. Car clay bar wiping: Use a car clay bar to wipe, as it has strong cleaning power and can thoroughly remove adhesive residue while also providing some polishing effect.

What is the Difference Between Horsepower and Power in Cars?

Horsepower is actually another way to express power, and horsepower and power can be converted into each other, but horsepower emerged earlier than power. The following is a related introduction about power: 1. Power and Fuel Consumption: There is no difference in engine hardware, but different performances are achieved by adjusting ECU data, combined with differences in vehicle configuration, to achieve different positioning of the entire vehicle. Turbocharged engines can control the turbocharger through the ECU to achieve different boost pressures, and it is relatively simple to reduce power by lowering the boost pressure. Generally, such engines are designed for high power, and reducing power will not cause reliability issues. However, for low-power engines that are not optimized, fuel consumption is basically the same as that of high-power engines. 2. Differences Between High and Low Power: Different versions of high and low power also have different valve structures. The low-power version, for better fuel economy, is equipped with a dual-cycle system. Simply put, by adjusting the entire valve structure, some power is sacrificed at low RPMs to achieve better fuel economy, which the high-power version does not have. This may also affect many supporting systems, such as cooling system pipelines, cooling fans, engine motors, and turbos.

How to Determine the Distance to the Rear Vehicle Using Rearview Mirrors?

The methods to determine the distance to the rear vehicle using rearview mirrors are: 1. If the rear vehicle is located on the outer side of the rearview mirror, it indicates a closer distance; if it is on the inner side, it indicates a farther distance; 2. The larger the rear vehicle appears in the rearview mirror, the closer it is; the smaller it appears, the farther it is; 3. When the internal rearview mirror shows the hood of the rear vehicle but not the grille, the distance is approximately 3 meters; 4. When the internal rearview mirror shows the grille of the rear vehicle, the distance is approximately 8 meters; 5. When the internal rearview mirror fully shows the wheels of the rear vehicle, the distance is more than 20 meters.

How to Check if Engine Oil Needs to Be Replaced?

Methods to check if engine oil needs to be replaced are: 1. Inspect the oil quality—if the color turns black and smells acidic, the oil needs to be replaced; 2. Use your fingers to check if the oil still has viscosity; 3. Difficulty in shifting gears when starting a cold engine. The steps to replace engine oil are: 1. Remove the air filter, clean it with an air pump, and reinstall it; 2. Lift the vehicle, unscrew the drain plug to release the oil, and remove the oil filter; 3. Add approximately 3.5 liters of engine oil. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and purifying; 4. Damping and cushioning; 5. Preventing rust and corrosion.
