Factors Influencing the Effectiveness of Air Injection in Reducing Exhaust Emissions

Automobile Exhaust Hydrocarbon Analysis by Gas Chromatography.

“…Gas chromatography has been employed for the separation of aliphatic amines in several instances. For the free amines, basic liquid phases or alkaline-coated supports are required to obtain separations (1,13,18,21). The more volatile amines are difficult to handle, however, and various techniques have been utilized to liberate the free base from the hydrochloride salts at some point in the gas stream (7,11).…”

California Vehicle Exhaust Control

“…Considerable research has been done on afterburners including the exhaust-manifold type to obtain low emissions of the three major pollutants. 9 …”
