What is the full form of CNG?
- Compressed Natural Gas
What is the full form of LPG?
- Liquefied Petroleum Gas
Methane compressed at a pressure of 200 to 248 bar is called CNG while a mixture of propane and butane liquified at 15 0C and pressure at 1.7 to 7.5 bar is called LPG.
Both have different uses but mainly both are used in the automobile as fuel nowadays while CNG is more popular and safe than an LPG because LPG is a highly inflammable and non-renewable energy source.
