An qeda uhlelo ngokuvamile amapayipi asetshenziselwa ukuqondisa amagesi e-exhaust asuka kude nokusha okulawulwayo ngaphakathi kwenjini. Lonke uhlelo luhambisa amagesi ashisiwe enjinini futhi luhlanganisa eyodwa noma ngaphezulu qeda amapayipi. Ngokuya ngedizayini yesistimu iyonke, igesi ephumayo ingageleza kokukodwa noma ngaphezulu kwalokhu:

Ikhanda lesilinda (inhlokweni) kanye ne-exhaust manifold noma i-extractor.
I-turbocharger yokwandisa amandla enjini.
Isiguquli se-catalytic sokunciphisa ukungcoliswa komoya.
A okuthulisayo (I-America esenyakatho) / isithulisi(UK/India), ukunciphisa umsindo.

Ipayipi lokukhipha umoya kufanele liklanywe ngokucophelela ukuthwala amagesi anobuthi kanye/noma ayingozi kude nomshini/injini. Amagesi avela ezinhlotsheni eziningi zemishini ashisa kakhulu; ipayipi kufanele likwazi ukumelana nokushisa, futhi akufanele lidlule noma lisondele kunoma yini engasha noma yonakaliswe ukushisa. Ushimula usebenza njengepayipi le-exhaust esakhiweni esinganyakazi. Ngenjini yomlilo yangaphakathi kubalulekile ukuba nesistimu yokukhipha umoya "ilungisiwe" (bheka i-exhaust eshuniwe) ukuze isebenze kahle.
