As we are shifting towards environmentally friendly transportation solutions, converting your vehicle to run on CNG (Compressed Natural Gas) or purchasing a new, more eco-friendly vehicle is a compelling option. For people considering a transition to a better alternative for the environment, CNG offers a great solution – in addition to reducing carbon footprint it also offers cost savings in the long run. 

CNG cylinder options for vehicles

When converting vehicles to CNG, there are several cylinder options to consider. Possible options include Type 1, Type 2, Type 3 and Type 4 cylinders, each having its own advantages in terms of weight, capacity and/or construction. Here are the main differences between each types:

  • Type 1 Cylinders are made of steel and are considered as the heaviest of all CNG cylinders. Type 1 cylinders are a cost-effective choice, suitable for different vehicle types.
  • Type 2 Cylinders have a metal liner surrounded by a composite shell, making it lighter than the previous cylinder type. Type 2 cylinders offer great balance between weight and capacity.
  • Type 3 Cylinders are made of similar materials as the previous type, but it has a metal liner encased in a composite shell with a carbon fiber wrap. Type 3 cylinder is lighter than previous type and has a high storage capacity. 
  • Type 4 Cylinders are the lightest and most innovative CNG cylinders. Type 4 cylinders consist of non-metallic, all composite construction making them lightweight, but still providing substantial storage capacity. 

CNG cylinder installation process

With each type of cylinder comes a different installation process with unique characteristics and requirements. Converting your vehicle to CNG involves a well-defined process which roughly consists of following:

  1. Vehicle assessment, as not all vehicles can be converted to CNG, a qualified technician should determine if your vehicle is suitable for the installation. 
  2. Cylinder selection should be made based on your vehicle’s requirements, available space and budget.
  3. Installation in your vehicle’s designated space, including fitting necessary brackets and mounts for stability. 
  4. Fueling system installation for CNG, including high-pressure lines and fittings.
  5. Safety measures are implemented: pressure relief devices, automatic shut-off valves etc.
  6. Testing and certification to ensure your vehicle’s functionality and safety.
  7. Training on operating and maintaining your CNG vehicle.
