As we are heading towards an era where safety and security is the main concern of every individual, the soundness of our family members is what we seek for them when they step out of the house, the CNG Kit is like a blessing to us. CNG fuel is far better and more affordable as compared to other fuels used in vehicles. Compressed Natural Gas is not only eco-friendly but also cheaper than petrol or diesel. CNG use is also supported by the government of India and as of now, 20 kits are already approved that are suitable for vehicle installation in India.

The basic components of CNG include Methane and CH4 and hence, CNG is considered comparatively better than even LPG or Liquid Petroleum Gas. CNG is lighter than other fuels and is less dense than air. This is a great advantage as now we know that CNG cannot catch fire even if it mixes with the air. CNG emits Carbon Dioxide (CO2) and a very less amount of Carbon Monoxide (CO3) which is good for the environment as a whole. Effective and better guidance for the safe installation of CNG users is offered by the Vehicle Research and Development Establishment (VRDE) or the Automotive Research Association of India (ARAI).

It is important to check that the emissions from the exhaust are within the permissible limit. It not only controls the CNG gas flow in the engine but also prevents excessive pollution.
