Is the car full of cng or lng?

The car was filled with cng. Compressed natural gas (CNG) is selected for automobile refueling because CNG is stored in gas cylinders at relatively high pressure at room temperature, which is low in cost, pollution-free, clean and efficient. Liquefied natural gas (LNG) is another form of natural gas, which needs to be liquefied at a lower temperature and then stored in a special thermos. It takes a long time and mileage to fill LNG, but it is not suitable for long-term parking. Therefore, it is more suitable for cars that run frequently, such as long-distance buses, buses and heavy trucks.
