CNG Conversion kit

The CNG conversion kit has the following main components are:

(i) Cylinder : It stores C.N.G at a working pressure of nearly 200 bar. It is also fitted with shut off valve and a safety burst disc.

(ii) vapour bag : This encloses the cylinder and the pipes connecting the cylinder valve vented out of the car. (iii) High pressure pipe : It connects the refueling valve to the CNG cylinder and pressure regulator. 

(iv) Refuelling valve: It is used to refuel the cylinder.

(v) Pressure regulator : It has a solenoid valve shut off supply to the engine. The C.N.G stored at high pressure in the cylinder is reduced to just below the atmospheric pressure by the pressure regulator. The pressure does not allow  when the engine is negative the gas to pass not running. 

(vi) Gas-air mixer : It mixes accurately the gas fed into the cylinder. 

(vii) Petrol solenoid valve : This is used to cut off the petrol or a diesel supply to the engine when it is run on gas. 

(viii) Selector switch : It is fitted on the dash board to enable the driver to choose whether the engine is to be run on petrol or diesel or CNG. This is so designed that when the engine is switched off the gas supply is also switched off. It indicate the quantity of CNG available in the cylinder.
