1. CNG is fed into the high pressure cylinders through the natural gas receptacle 2. When the engine needs natural gas, CNG leaves the storage cylinders and passes through the master manual shut-off valve.
3. CNG enters the engine chamber via the stainless steel high pressure line. 4The regulator accepts the CNG and reduces its pressure from 3,000 psi to approximate atmospheric pressure.
5. The natural gas solenoid valve lets the natural gas flow from the regulator into the gas mixer or fuel injectors. This same solenoid valve also shuts off the natural gas when the engine is stopped.
6. CNG mixes with air and flows down through the carburettor or fuel injection system and enters the engine’s combustion chambers.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
