An inkqubo zeemoto ihlala imibhobho isetyenziselwa ukukhokela ukusabela kweegesi kude nomlilo olawulwayo ngaphakathi kwenjini. Inkqubo iyonke ihambisa iigesi ezitshisiweyo kwiinjini kwaye ibandakanya enye okanye nangaphezulu khupha imibhobho. Kuxhomekeke kuyilo lwenkqubo iyonke, igesi yokukhupha inokuhamba kwenye okanye nangaphezulu koku:

Intloko yesilinda (i-header) kunye ne-exhaust manifold okanye i-extractor.
Iturbocharger yokunyusa amandla enjini.
Isiguquli sokuguqula ukunciphisa ungcoliseko lomoya.
A Ukutshiza (Amantla Emelika) / cwaka(UK / India), ukunciphisa ingxolo.

Umbhobho wokukhupha umbane kufuneka uyilelwe ngononophelo ukuthwala iigesi eziyityhefu kunye / okanye ezinobungozi kude kumatshini / enjini. Iigesi ezivela kwiintlobo ezininzi zoomatshini zishushu kakhulu; umbhobho kufuneka umelane nobushushu, kwaye akufuneki udlule okanye usondele nakweyiphi na into enokutsha okanye enokonakaliswa bubushushu. Itshimini lisebenza njengombhobho wokukhupha kubume obumileyo. Kwinjini yomlilo yangaphakathi kubalulekile ukuba inkqubo yokukhupha "ilungiswe" (bhekisa kwi-exhaust ye-tuned) ukuze isebenze ngokufanelekileyo.
