Advantages and disadvantages of LPG

The advantages of LPG are

• It is non-toxic, non- corrosive in nature.
• It burns cleanly and has high octane rating i.g. more than 100 RON (Research Octane Number).
• LPG engines have less knocking/ vibration.
• It does not produce harmful emission like CO, NOx and higher hydrocarbons.
• Particulate emissions are also less. So frequent cleaning of the combustion chamber is not required.

The  disadvantages of LPG are

• It causes suffocation, in case of leakage as it heavier than air.
• It is hazardous as it inflammable gas.
• It is consumed more as it has low energy density.
• It does not provide power to the vehicle in mountains or rough terrains.
• It is costlier than CNG.
• It has to be supplied in a heavy steel cylinder.
