How often should a car's air filter be replaced?

According to the car's maintenance manual, it is generally recommended to replace the air filter every 20,000 to 60,000 kilometers. If the driving mileage is low, it is suggested to replace it every 12 months. The location of the car's air filter element varies depending on the intake form and the engine's structure. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal wire mesh. The function of the air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders and preventing airborne dust from being sucked into the engine, which could accelerate the wear of the piston group and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinders, accelerating the wear of the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand from the air, ensuring that sufficient and clean air enters the cylinders. A dirty air filter: Using an excessively dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, composed of one or several air-cleaning filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinders, reducing early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, the air must pass through the fine filtration of the air filter before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have minimal dust and light blockage, it can be cleaned by blowing compressed air from the inside out and reused. Excessively dirty air filters should be replaced promptly.

What is the tire size specification for the Alto?

The tire size specification for the Alto is 155/65R14. In 155/65R14, the first number 155 represents the tire width of 155MM, 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 14 stands for the rim diameter of 14 inches. The middle letter "R" denotes a radial tire. Both the front and rear wheels of the Alto model feature a dynamic eight-spoke aluminum alloy design, and the spare tire is full-size. If you wish to replace the tires on your own, follow these steps: Retrieve the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack contacts the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned directly beneath the vehicle and is perpendicular to the ground; Remove the hubcap and loosen the nuts counterclockwise, but do not fully unscrew them—just enough to eliminate resistance. Keeping the tire on the ground when loosening the nuts for the first time ensures that the nuts turn, not the tire; Continue turning the nuts counterclockwise until they are loose, repeating this step for all lug nuts, then fully remove the nuts; Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and hand-tighten them until all nuts are snug. At this point, the tire replacement is complete. In addition to the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Shows the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".

How to Deal with Frozen Diesel in Cars?

For the treatment of frozen diesel in cars, the following methods can be used: 1. Open the engine hood and let the engine bask in the sun, then try to start the engine. 2. If it doesn't start, wait for 10 minutes and try again, repeating several times if necessary. 3. You can also use warm water to pour over the affected area or use an electric heating device to warm it up. Here are some preventive measures to avoid diesel freezing in cars: 1. Use diesel pour point depressants. It can effectively lower the cold filter plugging point and freezing point of diesel, improving its low-temperature flow performance. 2. Regularly add antifreeze. Adding antifreeze is the most convenient and easiest way to solve fuel freezing. 3. Let the car bask in the sun more often. Open the engine hood and let the internal engine and other parts bask in the sun to prevent fuel freezing. 4. Use diesel with a higher freezing point. In extremely cold weather, use diesel with a higher freezing point to avoid fuel freezing in low temperatures.

What are the differences between hatchbacks and sedans?

The differences between hatchbacks and sedans are as follows: 1. Different body lengths: Sedans are generally longer than hatchbacks. 2. Different structures: Sedans have completely separated engine compartments, passenger compartments, and luggage compartments, while hatchbacks integrate the passenger compartment with the luggage compartment by extending it rearward. 3. Different cargo capacities: The rear seats of hatchbacks can usually be folded or even laid flat to form a floor, allowing the trunk volume to significantly exceed that of sedans for transporting large items. 4. Different flexibility: In crowded urban road conditions, hatchbacks occupy less space than sedans and offer higher maneuverability. 5. Different fuel consumption: Under similar class conditions, sedans tend to have slightly higher fuel consumption than hatchbacks.

What does it mean when ETC shows 'Tag Invalid'?

ETC showing 'Tag Invalid' indicates that the device is currently unavailable and needs to be reinstalled and reactivated at the original processing point or any highway ETC service center. The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; a red light will briefly illuminate, and the OLED screen will display 'Tag Invalid' or 'Please Insert Card,' indicating the device is functioning normally. Clean the front windshield, ensuring the surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth On.' If 'Tag Invalid' appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually a QR code for download is provided on the electronic tag), then enter the device activation interface. Click 'Connect Device' and wait patiently for the 'Connection Successful' prompt. Once connected, upload a photo of the vehicle's front to complete the activation.
