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.
