Lone Star Gas Company, based in Dallas, Texas, is one of 25 American and Canadian companies taking part in a two-year field test of America's first factory-built vehicles designed to run exclusively on natural gas. Ford Motor Company designed and built the test fleet of 1984 Ranger pickup trucks. Each NGV Ranger is powered by a 2.3 liter four-cylinder engine with increased compression to take advantage of the high (130) octane rating of natural gas. Fuel economy with an automatic transmission is estimated by Ford to be equivalent to 21 miles per gallon for city driving, compared to 22 mpg for gasoline-powered Ranger. Based on current cost of natural gas and gasoline, the price of fuel is equivalent to 60-cent-per-gallon gasoline. The friving range is expected to be about 225 miles per fill-up for the Ranger being tested by Lone Star. The NGV Ranger Lone Star is testing has a number of modifications. It is equipped with fuel tanks constructed of fiber glass-wrapped aluminum, hardened valve seat inserts to compensate for lack of lubrication with a "dry" fuel, a sppcially designed gaseous fuel mixer to replace the carburetor, unique calibration of the distributor and spark plugs to accomodate the distinctive combustion characteristics of natural gas and a three-stage pressure regulator to reduce the natural gas pressure regulator to to reduce the natural gas pressure to slightly above atomospheric before induction into the engine.
