What are we looking at here?

[younkin]

I would like to know what the components of a basic CNG Kit are? I am not talking about a factory installed kit but one that is an add on? Thanks for any help, Jim

Re: What are we looking at here?

Tank,tank valve,tank mounting kit, fill nozzle, manual shut off valve, steel lines, high pressure regulator, heater hoses,switch valve, wiring kit, injector emulator, injectors, fuel rail, and some kind of a black box and/or reflash of the pcm

Did I miss something?

Here is a link for a guy converting a lawn mower engine.

In theory you could do the same thing with Natural gas except you have to carry enough fuel with you to make it with while. One GGE is about 128 cubic feet of gas. If you did not compress it the tank would be very large very fast. So you then have to put in a compressed air tank. You have to then regulate the pressure down to what the engine needs( perhaps .5 PSI and you tanks hold 3600 PSI).
Then of course you would want it to actually run right so that it does not screw your engine up or use more fuel then in gas mode. So, you have to put in some way to adjust the fuel mixture and timing. If its dual fuel then its got to be dynamic. It has to interface with the engines computer so the EPA is happy.

The most important component of all is expertise & formal training in high-pressure gaseous fuel systems.

Sounds simply enough. Where's my hammer............?

Cars roll down the road every day, they roll on Gas, Natural Gas, Propane
and Diesel. What makes them roll is all of the Machinists, Engineers and Mechanics that put the together and keep them running. The Politicians just screw things up. CNG cars will roll with or without the Politicians, Jim an old Mechanic.....

And always use ngv or dot hose and fittings
