Hello Guys,

I have recently installed CNG in my car.. every morning i can smell cng from the cabin..i went to the mechanic after checking he said everything is ok..he checked connections from cylinder..filler and kit .. everything seems ok but the smell is still coming up.. i told him to check the pipe coming from cylinder to kit but he said it a high pressure pipe and if it is leaked it will make sound..

i am still confused what to do ..please share you experience ..

Regards,

do not compromise on safety...i think your cylinder is leaking...do comprehensive checks by taking it off your car...by a qualified tech. if the smell is really bad...inhaling Natural gas is not good.

get the gas topped and go to a different guy to check for leak
if the smell is there, it is leaking!

get the leak checked with full cylinder & engine running. some leakages dont come up if engine is not running.

If your no return valve was opened than u have to change the farrul. Go to any good CNG mechanic and ask if farrul needs to be changed.

Well nothing to worry as I have noticed it that if the cylinder is filled too much, then smell keeps coming, but if you just fill 500, 600 rs, the smell does not come. I have also checked no leakages.

I normally get a full cylinder, but at some CNG stations when they unhook the nozzle the gas smell comes very strong. After the filling when I come home, I open the trunk and all doors to let the residual gas evaporate.

The smell came after I filled form Pearl CNG Gulrez. They keep the cars lined up and wait for the pressure to accumulate and then fill up slowly and I think that they over fill and that gas is leaked by cylinder's safety valve.
