Question
Dear Carl

http://en.wikipedia.org/wiki/Automobile
http://en.wikipedia.org/wiki/Compressed_natural_gas‎

Is it possible to install Multiple (More than one) CNG Cylinders in Automobiles  viz Medium and Heavy Vehicles viz Cars, Jeeps, Trucks, Lorries etc?.

I Feel the advantages would be double the Fuel storage capacity
in a automobile where in case one CNG Cylinder gets exhausted then automatically switching to the other CNG Cylinder as input Fuel source for the automobile.

Limitations could be the space required to fix the other extra CNG cylinder in the automobile ?.

Can this Limitation could be overcome in making space available for installation of another CNG Cylinder in the vehicle ?.

In terms of safety purposes do you recommend to have multiple CNG Cylinders in a automobile ?.

Awaiting your reply,

Thanks & Regards,
Prashant S Akerkar

Limitations to multiple cylinders would be the type of cylinders and the connections.  If multiple cylinders were to be used, local regulations should be checked, and top grade components should be used to guarantee the safety of the installation.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
