Authors Abstract
Content
Report discusses a joint exploration by Gaz de France and Saviem into using liquid natural gas (LNG) as a means of reducing urban pollution. Two distinct operations were undertaken simultaneously.
~ a Saviem mini-bus was adapted to LNG and a fueling station was set up in the Paris area.
~ Laboratory tests were conducted to determine an optimum performance - emissions relationship.
Results indicate that LNG operation has definite advantages for improving environmental quality and passenger comfort. Smoke emissions at starting or under load are essentially nil. Control of the ignition cycle assures reduction of the noise and vibration level. Emissions are comparable to those of a direct injection diesel, based on the 1977 American Emission Standards, at a sacrifice of power at maximum rpm, not a significant factor in urban operation. Technical possibilities will be strongly dependent on legislation.
