My point is that a lot of people wont consider a van for transportation
This will press most of this market to taxi use, delivery, etc. Will these
companies pay several thousand dollars more, per vehicle, to get one that
will burn CNG?
I doubt it, as long as gasoline is in the $3 range, and since the charging
facilities for CNG are few and far between, if they exist at all in a given
Yes, there is a potential fuel savings to be expected from CNG, if that
doesnt evaporate between now and the launch of such products.
99% of these will end up in state fleets or commercial fleets of
companies that want the tax write-offs.
The local NYS fish hatchery has a CNG powered P/U that they use and the
big fish delivery truck just had a $25,000 dollar exhaust installed on
it to "keep the air clean"
Figures....It was not uncommon to use liquified propane around here, some
years back. The conversion was dead simple, and the propane was cheap
and easy to come by.
Compressed natural gas, I mention because some relate this in their minds
to the propane systems of old, is a completely different tiger.
I think the Volt and this CNG van situation is more a publicity move
than a serious undertaking.
You are kidding, right? True electric vehicles like the Volt are expected
to capture nearly 10% of clean vehicle market in a few short years, that is
far more than the 2% of the market currently of hybrid sales.
You are confused, the Volt and its five coming derivatives, including a
pick-up are not hybrids, they are true electrics.
The only motive power, for the basic Volt chassis, are the two electric
motors in the transmission. The on board engine, that could be engineered
in the future to run on any of the available fuels, runs only the generator.
It can not power the vehicle, as is the case with any hybrid
IMO the best alt. fuel option is liquid propane injection but it requires a
booster or circulator pump to keep a solid column of liquid in the fuel rail
as the underhood temps would otherwise just boil off the propane and cause a
I dont know the details of such a system. The old systems worked with
duel fuel carburetors, IIRC.
Modern fuel injection systems work under considerable pressure anyway,
provided by the fuel pump.
While propane burns clean, the economic advantages, if any, can evaporate
quicker than the propane itself when the suppliers pump up the price and
our goofy government taxes it to death.
It isn't a CNG vehicle. It's a GM top kick diesel. BUT NY issued a
directive to all state departments that an attempt had to be made to
demonstrate clean air strategies.
So they went through most of the departments (currently the DOT is not
part of this but will be when they buy new vehicles) and started fitting
a ton of crap to vehicles to "clean the air" ,this system is a retrofit
unit that works a lot like the newer Ford units that run a converter and
purge system. The average cost on them has been close to 30K EACH. On a
truck that is worth maybe 15K!!!
The day I was visiting the crew was in the process of replacing one of
the band clamps to the manifold. Got to look over the unit and it's
It is a lot like the unit that is sold for retrofit onto fire equipment
that Ward products sells. We were actually looking at them for a couple
of our rigs until we priced them!
We run a mixed lot. Two Alfs, an E-one, a 4-Guys and a Wheeled Coach
that we run as a light rescue. Plus a Saulsbury unit that is currently
leaking engine oil faster than the well in the Gulf. Didn't leak until
the current repair guys touched it.
