| Summary: | Natural gas engines are unique. They operate in a variety of unusual locations, from the extremely cold climates of arctic Canada to the hot, humid regions of the southern United States and beyond. Natural gas engines are of various designs, including the Caterpillar vertical in-line and V type four-stroke, the two-cycle Cooper Bessemer V type integral with a horizontally opposed reciprocating compressor and the dual crankshaft, vertically opposed, two-stroke engine built by Fairbanks Morse. These engines are required to burn a variety of gases including, but not necessarily limited to, sour gas, containing sulfur; sweet gas, containing no sulfur and very little carbon dioxide; wet gas, containing relatively high quantities of component gases such as butane; and finally, landfill or digester gas, composed primarily of methane and carbon dioxide and which frequently contains halogens such as fluorine and chlorine. In addition, in most jurisdictions where these engines operate, exhaust emissions have become a serious concern. To control or eliminate these emissions, some of the current engine designs require catalytic converters, which limit the additive types and the formulated |
