Inzwa ye-MAP (ingcindezi enkulu kakhulu / ingcindezi yomoya)

Inzwa ye-MAP (Manifold Absolute Pressure, kwesinye isikhathi ibizwa nangokuthi iManifold Air Pressure) isetshenziselwa ukukala ukucindezela (phansi) kokuphindaphindwayo kokudla. Inzwa idlulisa imininingwane kwiyunithi yokulawula (i-ECU), esebenzisa lolu lwazi ukulungisa isilinganiso sikaphethiloli somlilo omuhle kakhulu.

Le nzwa ivame ukutholakala kokuphindaphindwayo kokutholwa phambi kwe-valve mpintsha. Ukuze idatha yenzwa ye-MAP ibe nenembe ngangokunokwenzeka, inzwa yokushisa nayo iyadingeka ngoba ukukhishwa kwenzwa ye-MAP akubuyiseli izinga lokushisa (lena idatha yedatha kuphela). Inkinga ukushintsha kobude noma ushintsho ekushiseni komoya owuthathayo, kuzo zombili izimo ubukhulu bomoya buyashintsha. Njengoba ukuphakama kukhuphuka, kanye nezinga lokushisa lomoya odlayo, ubukhulu bayo buyancipha, futhi uma lezi zinto zinganakwa, amandla enjini ayancipha. Lokhu kuxazululwa yisinxephezelo sokushisa esishiwo ngenhla, kwesinye isikhathi ngenzwa yesibili ye-MAP elinganisa ingcindezi esemkhathini yomkhathi. Ukuhlanganiswa kwenzwa ye-MAP ne-MAF nakho akusetshenziswa kakhulu. Inzwa yokugeleza komoya ngobuningi, ngokungafani nenzwa ye-MAP, ilinganisa inani lomoya, ngakho-ke izinguquko zengcindezi aziyona inkinga. Ngaphezu kwalokho, umoya ungaba kunoma yikuphi ukushisa, njengoba kukhona isinxephezelo sokushisa lapho uphuma khona ocingweni olushisayo.
