Umsebenzi wempompo yokucoca i-automotive vacuum kukuvelisa uxinzelelo olubi kwaye ngaloo ndlela ukwandisa amandla okunyathela.Kwizithuthi eziqhutywe ngeenjini ze-diesel, i-vacuum pump ifakwe ukubonelela ngomthombo we-vacuum, njengoko injini ine-CI yokunyanzeliswa kwe-ignition, ukwenzela ukuba inqanaba elifanayo loxinzelelo lwe-vacuum alikwazi ukubonelelwa kwi-manifold intake.
Umthetho-siseko wokusebenza kwempompo yokufunxa iimoto, okokuqala kuzo zonke iimoto ezixhotyiswe ngeenjini zepetroli, kukuba i-injini iqhelekile yohlobo lokulayita, ukwenzela ukuba uxinzelelo oluphezulu lwevacuum lunokuveliswa kwisebe lokungenisa.Oku kunokubonelela ngomthombo wokucoca owaneleyo wenkqubo yokuqhawula amandla e-vacuum, kodwa kwi-injini ye-diesel izithuthi eziqhutywayo, kuba injini yayo isebenzisa ukuvutha koxinzelelo, ngoko ke kwisebe lokungenisa ayikwazi ukunika inqanaba elifanayo loxinzelelo lwe-vacuum, efuna ukusetyenziswa impompo yokucoca inokubonelela ngomthombo we-vacuum, ngaphezu koko kukho izithuthi ukwenzela ukuhlangabezana nokukhutshwa kweemoto ezithile kunye neemfuno zokusingqongileyo kwaye ziyilwe ngaphandle kwe-injini kufuneka ibonelele ngomthombo owaneleyo we-vacuum ukuqinisekisa ukuba imoto inokuhamba ngokufanelekileyo.
Ukukhutshwa kwempompo ye-vacuum ubukhulu becala kuxinzelelo oluveliswa yinkqubo ye-servo yamandla, kodwa xa ingasebenzi kakuhle, isenokuthi iqhutywe ngamandla omntu kwi-hydraulic system, ukuba idlale indima kwi-booster.Inkqubo ye-vacuum braking nayo inokubizwa ngokuba yi-vacuum servo system.Inkqubo yesiqhelo yokuqhoboshwa kweemoto, ngokubanzi ixhomekeke kuxinzelelo lwe-hydraulic njengesixhobo sothumelo, kwaye emva koko xa kuthelekiswa nenkqubo ye-braking ye-pneumatic enokubonelela ngamandla, kuyimfuneko ukubonelela ngenkqubo yokumelana nokubonelela ngoncedo lokunyathela umqhubi.
Ipompo yokufunxa ikakhulu isebenzisa i-vacuum eyenziwe yi-injini xa isebenza ukunika uncedo olwaneleyo kumqhubi xa efaka iziqhoboshi, ukuze umqhubi akwazi ukufaka iziqhoboshi ngokulula nangokukhawuleza, kodwa xa impompo yokufutha yonakalisiwe, ayinanto ithile. Ubungakanani boncedo, ngoko xa ufaka iziqhoboshi uya kuziva unzima ngakumbi, kwaye umphumo weziqhoboshi uya kuncitshiswa, kwaye ngamanye amaxesha uya kusilela, oku kuthetha ukuba impompo yokucoca yonakele.
