As we know all types of vehicles can run on CNG by installing CNG kit. Kit is assembling of many components required to run existing vehicle on CNG. There are few basic components which are common in all type of kits, irrespective of the vehicles such as CNG storage cylinder, high pressure tube, pressure regulator, pressure gauge, change over switch, high pressure tube fittings, refueling receptacle and air fuel mixer. While conversion of any vehicle into CNG mode, we must keep remember:
- The CNG kit installed in the vehicle should be insured along with vehicle accessories. The motorist should notify the insurance company to provide insurance on the CNG system, for which additional premium may be charged by the insurance company. Motorists should take the insurance cover for the additional CNG kit system.
- As per present government regulation the pollution check and a pollution certificate is mandatory even after converting the vehicle on CNG.
- A pressurized gas cylinder is probably the strongest component on the vehicle. Vehicles that were totally destroyed in collisions show the only discernible component being the intact gas cylinder. It is unlikely that cylinders will rupture due to collision impact.
- Regarding the danger of fire from leaking cylinders, all we have is the experience to date that indicates that such an event is unlikely to occur. The risk of fire from leaking cylinders must be low since there are well over 03 million CNG vehicle installations worldwide that have not experienced such problems.
- It is worth pointing out that natural gas is lighter than air and in the unlikely event of a leak from piping or container the gas will dissipate upwards quite quickly. In the case of petrol and LPG the vapour given off is heavier than air and will tend to pool near the ground.
