1. Intro

With rising pollution in the country particularly in all the metro cities, the government has no choice but to implement stricter exhaust emission norms. BS6 emission regulations will be implemented for the 1st of April this year. CNG fuel is considered a green fuel, emitting less harmful exhaust gases.

This has lead to the development of different ways suitable for reducing the number of harmful gasses emitted from the exhaust of the vehicle. Different ways include the introduction of 100% electric vehicles, making some big or small changes in diesel as well as petrol engines to meet those requirements. One such option is amongst us for a long time and has got more reliable than before. Installation of CNG (Compressed Natural) Gas kits in the petrol vehicles. 

CNG not being safe is a myth. Now through several years, the technology to run petrol cars on CNG has become safe as well as more efficient.CNG kits are getting more and more popular due to the gradual increase in the prices of diesel and petrol. CNG on an average cost around Rs.40/Kg which is way less as compared to the other two. Running your car on petrol and CNG have their pros and cons.

2. Which is better – Petrol or CNG?

Both CNG, as well as petrol, have their own pros and cons depending upon the parameter. The ways through which a fuel can be studied are.

  • Performance–  Petrol leading this hands down. An engine running on petrol has more power as compared to its counterpart. 
  • Economy– Considering the price of petrol and CNG petrol is a less economic solution. The cost of petrol per liter is more as compared to the other fuel. Added to that is the cost of long term CNG vehicles is more as compared to the petrol car. Yet doing the math and adding all the affecting factors CNG is about Rs. 3-4 per Km cheaper than its rival fuel.
  • Pollution– Petrol emits more harmful gases like Nox and Cox, on the other hand, CNG is more known for producing reduced harmful gases but emitting less harmful Greenhouse gasses.
  • Convenience– The worst drawback of CNG is the reduced boot space to accommodate the huge CNG cylinder. CNG as a fuel is not available everywhere. Installation may lead to a change in the vehicle dynamics of the vehicle.
  • Safety- Considering the fact that CNG is safe but not as safe as petrol. Being a gas it is more prone to leakage and catching fire.
