Isistimu yokuhlola inzwa eyirimothi evundlile isebenzisa ubuchwepheshe bokumuncwa kwe-spectral ukuze ithole ukukhishwa kwe-carbon dioxide (CO2), i-carbon monoxide (CO), ama-hydrocarbon (HC), nama-nitrogen oxides (NOX) aphuma exhaphozini yezimoto. Lolu hlelo luklanyelwe kokubili izimoto zikaphethiloli nezadizili, futhi lungakwazi ukubona ukungaboni ngaso linye, i-particulate matter (PM2.5), kanye ne-ammonia (NH3) kaphethiloli nezimoto zikadizili.
Isistimu yokuhlola inzwa yerimothi evundlile ihlanganisa umthombo wokukhanya kanye neyunithi yokuhlaziya, iyunithi yokubonisa i-engeli engakwesokudla, uhlelo lokutholwa kwesivinini/ukusheshisa, isistimu yokuhlonza imoto, isistimu yokudlulisa idatha, isistimu yekhabhinethi lokushisa engashintshi, isistimu yesimo sezulu kanye iyunithi yokusebenza, engalawulwa ukude ngenethiwekhi.
