CNG Dual Fuel?

[BlackWorksInc]

Homey is correct. The most practical way I have read about is a bi fuel mixture which is basically an efficiency exercise. What happens is this:
You start out and accelerate with gasoline
After reaching cruising speed the new coprocessor switches over to CNG

The basic parts needed are a coprocessor, additional gauges, a 4 gallon tank and the biggie is new fuel injectors + plumbing.

The price is around $3,500.00 once they get it up to a decent quantity.

The small CNG tank will add range at a reduced cost thereby making your vehicle more efficient from a cost perspective, not from a true mechanical efficiency point. There are inherent advantages and disadvantages to both fuels. This method looks to use the advantages of CNG (low cost) and minimize the disadvantages of CNG which are low temp performance and lower energy output by using gasoline in startup and acceleration conditions.

Last point: To those posters that think adding a CNG tank to the bed of a truck is safer than adding it to the inside of a SUV need to realize that if that tank blows sheet metal will not even slow it down. With that said, CNG is as safe as the vehicle you are driving now and maybe safer depending on the statistics.

Interesting, I was wondering how aftermarket add-on kits work with the factory PCM... Other than finding someone who knows what they are doing to install the kit properly and safely... I would be skittish of putting a 3500psi tank IN my vehicle and would want some sort of Kevlar blanket and/or shroud built to deflect damage in the event of a rupture...

They don't rupture like and explosion, they get a hole or cracked and spew gas. The engineer I work with has done lots of test on these. There are some videos on YouTube.

But I know what you mean - it's still to me like having a bomb in the car to me. The tahoes we have have tanks in the spare tire area under the truck. Ill take a pic on Monday.

I'm thinking more like Scuba Tank or other non-explosive pressure container failures... a jet of compressed gas is not something to trifle with... and if its mounted so it can't get away I would not be surprised if it cut through some shrimpy sheetmetal if the orifice is small enough...

Greg,

I've been enjoying a lot of your posts, lots of wisdom.

Problem:

Your avatar ain't working for me!

I respectfully suggest a solution:



Hopefully we can reach a compromise...
