Why do cars need to be fueled with gas?

Refueling cars with gas involves using natural gas as fuel, primarily for taxis and buses. Private cars cannot pass annual inspections after modification, but once modified, they can be fueled with natural gas to run on it. Taxis are fueled with CNG (Compressed Natural Gas). Related information: 1. Introduction: CNG can be sourced not only from natural gas fields but also from artificially produced biogas. Some city buses also run on this type of gas. LNG is Liquefied Natural Gas, which turns into CNG (Gasified Natural Gas) after vaporization. 2. Precautions: During refueling, the pressure in the gas cylinder increases from low to high, posing certain risks. When refueling at a gas station, all electrical devices and the engine should be turned off to prevent sparks caused by static electricity or short circuits, which could lead to explosions. It is advisable for gas-fueled cars to carry a fire extinguisher, as it can be very useful in emergencies. In summer, avoid keeping flammable or explosive items in the cabin, such as lighters.

To be honest, after driving for so long, I've realized that inflating tires isn't just routine maintenance—it's a major safety issue. If the pressure is too low, the tires go flat, making the car wobble and increasing the risk of skidding or losing control during turns. I experienced this last year when I forgot to check the tire pressure before a long trip. Halfway through, the tire overheating alarm went off, and I nearly had a blowout—it was terrifying. On the other hand, overinflating is no good either. The ride becomes harsh and bouncy, making it uncomfortable, and the center of the tire wears out much faster, forcing you to replace them prematurely and waste money. Keeping the pressure at the manufacturer's recommended level ensures a stable ride on highways and even saves some fuel costs. Remember, don't skip this step—especially before long trips. A quick check can prevent major disasters.

As a young driver who just learned to drive, I think inflating tires is one of the most basic car maintenance tasks. It directly affects the wallet - when tire pressure is too low, the tires deform and expand, increasing friction and causing fuel consumption to rise sharply. I've calculated that it costs dozens of yuan extra in fuel each month. More importantly, uneven tire wear means having to replace them after just one year, which is quite costly. If the pressure is too high, the car body becomes too rigid, making bumps on rough roads uncomfortable and reducing driving pleasure. I make it a habit to check the pressure weekly with an inexpensive gauge - it takes just one minute. This way, driving feels stable and secure, while also extending tire life. The money saved can buy a few extra cups of coffee.

Maintaining proper tire pressure is crucial for the overall health of your vehicle. Underinflation causes excessive tire deformation, increasing rolling resistance, which not only reduces fuel efficiency but also subjects the suspension system to additional stress, gradually damaging component lifespan. Conversely, overinflation reduces tire contact area, compromising braking performance and significantly diminishing ride comfort. I always check the pressure when washing my car to ensure it stays within the recommended range. Regular inflation also prevents tire pressure sensor failures and reduces unexpected repair costs – simple maintenance yields great returns.
