Post subject: Compressed Natural Gas (CNG) fuel Conversion For Light Truck
Reply to Nehmo Reply with quote





Although I don't have any experience in converting a gasoline engine
to use CNG (actually the finished engine will be duel fuel, able to
use either gasoline or CNG), I have a customer who wants four vehicles
converted. Because of the customer's access to natural gass, it's
economically a reasonable idea for him.

I also have a highly experience mechanic in the shop who did a
conversion some years ago. I plan to research the job, and then do it
if feasible.

I've looked over the some sites on the subject:

An overview from the California Energy Commission
www.consumerenerg....ng.html

The Wiki
en.wikipedia..../....ral_gas

Utah pdf
www.deq.utah..../....208.pdf

Converting your Vehicle
www.ngvamerica.or....GVs.pdf

Pickens
www.cngnow..../EN....lt.aspx

list of all currently available EPA- and CARBcertified engine
retrofits
www.ngvamerica.or....s-a.pdf

Another overview from Louisiana
dnr.louisiana........cng.htm

Pop Science on the Honda
www.popsci..../ca....guzzler

I'm in Kansas City, USA. Over here, there aren't many vehicles that
run on CNG compared to, say, Australia. However, I suspect that the
now high price of gasoline will bring the people of US to try more
alternative fuels. CNG (or more likely, duel-fuel) will be an
option.

I haven't seen a decent thread on this subject recently. Does anyone
have a comment, info, or opinion? Has anybody did a conversion
recently? Let's hear what you have to say.

Years ago (around the late 70's or early 80's) here in New Zealand the
government announced a subsidised plan to convert a target of 150,000
vehicles to run on CNG, and there was quite an extensive adoption of CNG,
and a reasonable network of filling stations set up etc.  Not much left of
this now!

The company I worked for at the time developed a small range of high
pressure equipment (filling valve, pressure regulator, and a clever
conversion kit which allowed the standard "gasoline" fuel gauge to be used
at the flick of a switch to display either gasoline contents or CNG
contents).  We soon had a tidy export business selling this equipment in
Canada and USA.  One of our USA customers was Impco, who supplied the Impco
conversion kit for CNG.  I recall their equipment was highly regarded and
had a genuine gas carburettor (as opposed to the cruder metering methods
used by some other brands of conversion kits).

I'm retired now and not familiar with what equipment is available but you
may find it useful to contact Impco if they are still in business in the
USA.

Cheers,

John S


Not sure if this helps but notice a lot of Garbage trucks
(freightliners ) here on CNG
can ask about if it is a help

There is a store/shop very near me.(Moulden Supply) They convert
vehicles to run on propane.I think they also do CNG conversions too.

There's a fair proportion of UK cars converted to Duel-fuel using LPG
(usually a propane / butane mix) due to a large difference in duty between
petrol and LPG. Most opinions seem to be that LPG gives slighlty less power
(but at about half the price here!). You might find more data on
conversions on UK sites. (The rest of us that don't want to drive round
with a gas cylinder in the boot run diesel cars - modern turbo common rail
diesels being as nippy as a petrol car, and much more economical)

I did a websearch recently and found a decent site where they have the
technology to
covert fuel injection vehicles (particularly important since carbureted
small cars are
all but dinosaurs).

The Phill (sp$) system is available to compress your own natural gas, but it
seems
to be a bit expensive. Probably safe, but also requires periodic
maintenance...good for
a number of rebuilds. I feel one could engineer his own compressor system,
but could
also end up winning a Darwin award.

If you cant find the first site, I will see if I can retrace my steps.

The main problem is that methane will not liquify when compressed at
ambient, so you will have to design in a high pressure storage system

CNG & LNG storage systems exits, so designing one isn't necessary.
