Re: 84 Thomas - The Yankeflyer

Compressed Natural Gas



Compressed natural gas works very well on turbodiesels. It has a very high octane rating which allows the use of a high percentage of gas to diesel. CNG is less expensive than propane, often substantially less, which will reduce operating cost significantly. It offers the same power increase as propane, around 100 horsepower on the current diesel engines from Detroit. Since it is stored as a gas and not a liquid, it doesn't have the range of propane. More frequent refueling is required, but with a refueling appliance attached to a residential gas supply, you can refuel frequently and conveniently at home. Tanks are available from 2.5 gal to 45 gal GGE (gasoline gallon equivalent).

Since cng isn't liquified, it is sold by the GGE. This means that you are buying the equivalent amount of energy as in a gallon of gasoline. Gasoline is approximately 125,000 BTUs per gallon. Natural gas varies in energy content depending on its composition. Natural gas is mostly methane, but contains propane, butane, and a number of other hydrocarbons. Because of this, a cubic foot of natural gas can range from 1000 to 1500 BTUs. The weight of the fuel is proportional to its energy content, so rather than sell it by the cubic foot, it is sold at refueling stations by the pound. For every 5.66 lbs of fuel, you are charged for a GGE. This way, no matter the energy content of the fuel, you are paying by the BTU rather than the volume. CNG tanks are often sized by the GGE rather than the liquid volume the way propane tanks are sized. A tank that would hold approximately 40 liquid gallons will hold around 10 GGE at 3600 PSI.

Prices vary a lot for CNG at refueling stations, ranging from as low as $1.00 to over $2.50 elsewhere. The real savings comes by refueling from home. Small compressors, often called home refueling appliances, are available to refuel at home. It attaches to the gas supply in the house, and is located in the garage or area where the vehicle is parked. A hose attaches to the vehicle, allowing refueling anytime the vehicle is home. We now have compressors available starting at 1.4 GGE per hour pumping rate. This would fill a 12 gallon tank in about 9 hours. Storage tanks are available to quick fill vehicles.

The supplemental CNG system used on a Chevrolet Silverado with Duramax engine has increased the diesel mileage from 18 mpg to 55 mpg. Bear in mind that there is no magic occurring here, the diesel is being replaced with cng. The approximate cng mileage achieved was 25 mpg. The following shows the math:

#2 diesel price $3.30/gal

CNG price $1.49/gal

Price to drive truck at 18 mpg running on #2 only $3.30/18 = 18.3/mile

Price of #2 to drive truck at 55 mpg running on #2 and cng $3.30/55 = 6.0/mile

Price of cng to drive truck at 25 mpg running on #2 and cng $1.49/25 = 6.0/mile

Combined price of the #2 and cng per mile 6.0 + 6.0 = 12.0/mile

Savings per mile is 18.3 - 12.0 = 6.3/mile

The savings will be greater using fuel compressed at home. A typical price for gas is 92 per therm. A therm is 100,000 BTUs, so when adjusted to a GGE it costs 92 x 125,000 btu/100,000 btu = $1.15/GGE. The compressor will add a cost of somewhere between 10 and 20/gal in electricity to operate.

Uncompressed natural gas $1.15

Ongoing electricity cost 10 - 20

Total cost of gas not including compressor cost $1.25 - $1.35/gal

We have compressors available. Call for more information about them.

CNG is also excellent to use as a supplemental fuel on stationary engines. If natural gas is available, there are no pumping costs to compress the gas. It works well on diesel gensets and other uses, such as tractors that are used to grind feed and run long periods without being moved. Hybrid units are available that allow low pressure gas and high pressure gas to be used. When using low pressure gas, the line is attached to the unit with quick couplings. We have stationary diesel engines as small as 15 HP and as large as 1000 HP using supplementary natural gas.

Keep in mind that besides the savings, you will have more available horsepower. If you would like to find out more, contact us. Below is a picture of a typical CNG injection assembly.

To see the pic and thier website http://delucafuelproducts.com/Compresse ... %20Gas.htm - this is all new to me - now I wonder what it takes to convert my propane tanks to natural gas tanks.

Re: 84 Thomas - The Yankeflyer

LL - spent a lot of time in doors lately - working on the portfolio.

The tankless water heater would have vented through the roof right above where hangs. The propane line is run to the twh but not sealed yet. Your place look comfy and reminds me of my first couple years in the bus.

mama said no - too much work to finish - but Dwight liked what I have done - drove all the way up from Dallas to see.

Re: 84 Thomas - The Yankeflyer

Ya I`m reading more everyday - The tanks are expensive compared to propane. The conversion kit for my Passat is 500 dollars. http://cgi.ebay.com/ebaymotors/DELUX...ltDomainQ5f100http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

Utah comes up a lot when looking for price and avalibilty - The state has activley promoted cng conversion.

Re: 84 Thomas - The Yankeflyer

I just had the local heavy metal band come by and look at the bus. They were trying to buy it for a song.
