CNG conversion kits for diesels
 

Any one running cng?

it is a huge deal to convert and then its nolonger a diesel ...can you say spark plugs real engines dont have spark plugs :)

I was doing some research on that, i can't find the site right right now but they were adding CNG in diesel fleet vehicles up to something like 70%. They were still using diesel fuel for combustion, but adding CNG to off set the use off it. No spark plugs.

This is not not the site i was looking for but it touches on it

my work truck is one...gut less but cheap

Would that be similar to propane injection, just using natural gas instead?

I pulled this form another site Diesel conversion

"Nowadays, conversion of Petrol run vehicle into Gas run vehicle is very common. Owners of petrol run vehicle are very satisfied with their gas system. But we have good news for the owners of the diesel run vehicle. They can also save their fuel cost by getting converted their engine into gas system.
There are two types of conversion:

* Dedicated gas system
* Dual fuel system

In a dedicated system the vehicle will run only on gas. There will be no option for diesel. The conversion cost is high and saving will be more than 70%.

But in dual fuel system the vehicle will run both on gas and diesel at the same time. Engine will get 20% Diesel and 80% Gas. The conversion cost is less and saving will not be more than 50%.

In both systems Engine gets clean fuel so the life of engine increases and maintenance cost reduces. Engine runs with no power loss and generates same torque as before. As in conversion engine goes under major overhauling it acts as a new vehicle. "

I didn't know people were converting diesels to run only on CNG, seems like a lot of work when you could just start with a gas engine. http://www.afsglobal.com/faq/diesel-...onversion.html

The only problem with CNG is storing enough fuel to make it viable at such high concentrations. With Propane, it only needs about 200 psi to be liquid state and vaporizes as you need it. CNG doesn't liquefy even at 2000 psi, which by the way you would require much heavier storage mediums, as most systems are like oxygen cylinders at 2000+psi. I would just be a little leery about having a bundle of missiles in the back of my truck.. Ever see the safety vids on a cylinder with a knocked off valve?

I did see the aftermath of a scuba tank loosing its valve in the back of an exploder. Had a nice vent in the back door after that. Probably be similar to that, but with a Ka-Boom mixed in for good measure.
