Tired Of High Gasoline Prices? Consider The Alternative
B Y A NDREW G OROSKO
People attending a demonstration sponsored by PRS International this week got
a sense of what the near future may hold in terms of automotive fuel
technology.
At PRS International on Commerce Road, participants strapped themselves into a
full-sized, four-door 1996 Ford Crown Victoria police car. The vehicle is a
marked police patrol model rigged with a heavy-duty frame, body mounts,
suspension and braking system.
Unlike a conventional power plant which burns gasoline, the 4.6-liter V-8
internal combustion engine which powers the car burns compressed natural gas
(CNG).
The automobile was provided to PRS for demonstration purposes by Ford Motor
Company of Dearborn, Mich, and Connecticut Natural Gas Corporation of
Hartford.
"It is a chance for us to test drive what is arguably the immediate future in
terms of automotive and fuel technology. What Ford and Connecticut Natural Gas
have done is to marry two familiar technologies - the internal combustion
engine and natural gas - and create a viable source for alternatives to
`normal' gasoline-powered vehicles," according to David J. Franus, PRS
International's group director for power systems and infrastructure.
The Ford's engine runs extremely smoothly on the natural gas fuel. Compared to
a gasoline-powered engine, emissions are very low. The engine runs so quietly
it can be considered a "stealth" car, Mr Franus said. Powering a car by
compressed natural gas is actually safer than running it on gasoline, he
added.
Scott Allo, an automotive analyst for PRS, said some other alternative fuel
technologies, such as electrical-powered automobiles or fuel cells, are
limited by current technologies or are still in research and development.
Compressed natural gas exists and is being used in the US to power bus fleets
and automotive fleets, according to a PRS statement.
Mr Franus, Mr Allo, and Julius Fabrini, a PRS analyst, tested the big Ford in
the areas of responsiveness, acceleration and quietness.
The vehicle which was demonstrated at PRS Monday runs only on compressed
natural gas, unlike "bi-fueled" vehicles which can run on natural gas or
gasoline.
The sedan's fuel capacity is 1,240 cubic feet of gas, comparable in size to a
10-gallon gasoline tank. The car has a range of about 180 miles under normal
driving conditions, according to PRS. The gas is kept compressed at 3,000
pounds of pressure per square inch.
According to Mr Franus, Ford is the only major auto manufacturer which sells
vehicles powered by compressed natural gas. Chrysler left the market this year
and General Motors is expected to re-enter it next year.
The are five compressed natural gas fueling stations open to the public in the
state. People who use compressed gas vehicles on a regular basis can obtain
hardware that allows their vehicles to be refueled overnight at home.
Although CNG-powered vehicles cost more than conventionally-powered vehicles,
savings on fuel and vehicle maintenance make up the difference, according to
PRS. CNG isn't taxed as a motor fuel.
"One of the nice things about compressed natural gas is it's a North American
product," Mr Franus said, commenting on the volatility of overseas petroleum
markets.
