WebThe exhaust gas is introduced into the analyzer through a probe maintaining the temperature of 191 C (Fig. 1b). Then, the particulate matter is ﬁl- tered out (diesel engines) and the exhaust gas is directed to the ﬂame-ionizing detector where the concentration of THC (total hydrocarbons) is mea- sured. WebTherefore, the exhaust gas contains pollutant emissions such as: carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM). All pollutant emissions from internal combustion engines have harmful effect on human life and environment. Nitrogen oxides form at high temperature and when there is oxygen in excess.
