Compressed Natural Gas has surged in popularity as an ideal alternative to regular fuels like diesel and petrol. CNG owes its usage growth to factors like economic viability, eco consciousness and safety. As a result, there is an ever-expanding CNG segment of popular cars in India.

Before we dive into all the technicalities of CNG-run automobiles, it’s important to be acquainted with the fuel and how it is obtained. CNG is the compressed form of natural gas, which is then stored in containers under pressure conditions of 2900 – 3600 psi. The naturally occurring fuel has major advantages for customers who choose to opt for this alternative. Usually, vehicles are modified to support CNG at the behest of their owners; however, the number of CNG vehicles (specifically designed for CNG) is also increasing day by day. As opposed to higher installation costs when these first arrived, CNG kits have made the installation of a CNG system in any car of choice extremely easy.

The Government of India has ratified the use of 20 CNG kits and individuals looking for more cost-effective solutions to their everyday fuel expenditure are rapidly educating themselves about benefits of the same. CNG kits are available in two different types- Venturi CNG and Sequential CNG, the former is a more affordable and easier option to install while the latter is considered to be a more refined kit. The Venturi kit can be installed in any kind of vehicle without any ECU (electronic control unit) or sensors while the Sequential kit requires both for its installation. Also, the latter controls fuel-inflow and can only be fitted in a vehicle with an electronic fuel-injection system.

Sequential CNG has an open and closed loop system subject to whether the vehicle uses Lambda or Oxygen sensors. Depending on the type of kit chosen, a typical OBD II (on-board diagnostics) would cost INR 55,000 and INR 33,000-37,000, closed-loop kits range from INR 22,000-25,000 and open-loop can be installed for INR 15,000-20,000. Customers should also expect additional charges of up to INR 4,500 for registration and insurance endorsement. India has nine cars in its CNG segment: starting with the lowest priced Alto variant LXi CNG at INR 4.37 lakhs, prices gradually climb with the CNG trims of Maruti Suzuki Eeco, S-Presso, Wagon R, Celerio, Hyundai Santro, Grand i10 Nios, Aura and Ertiga at INR 8.95 lakhs.
