Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use. |
Exhaust Gas Analyser
Device for determining the relative amounts of carbon dioxide, oxygen and carbon monoxide present in exhausts. There are various types of analyzer. One simply measures the thermal conductivity of the gases and recording on a galvanometer whether the fuel-air mixture is rich (excess carbon monoxide) or lean (excess oxygen). Another type involves an endiometer where the exhaust gases are bubbled through a succession of chemical solutions which respectively absorb carbon dioxide, oxygen and carbon monoxide. More sophisticated types can ascertain the content of pollutants. |
