Why do cars need to be fueled with gas?

[ORowan]

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.
