Ngenxa yokuba amandla athile obushushu bamanzi makhulu, ukunyuka kobushushu emva kokufunxa ubushushu bebloko yesilinda akuninzi kangako, ngoko ke ubushushu benjini budlula kwisekethe yolwelo lwamanzi abandayo, ukusetyenziswa kwamanzi njengesithwali sobushushu esithwala ubushushu, uze udlule kwindawo enkulu yesinki yobushushu ngendlela yokuchithwa kobushushu be-convection, ukuze kugcinwe ubushushu obufanelekileyo bokusebenza kwenjini yejenereyitha yedizili.
Xa ubushushu bamanzi enjini yejenereyitha yedizili buphezulu, ipompo yamanzi ipompa amanzi ngokuphindaphindiweyo ukunciphisa ubushushu benjini, (Itanki yamanzi yenziwe ngetyhubhu yobhedu engenanto. Amanzi obushushu aphezulu angena kwitanki yamanzi ngokupholisa umoya kunye nokujikeleza ukuya eludongeni lwesilinda yenjini) ukukhusela injini, ukuba ubushushu bamanzi asebusika buphantsi kakhulu, ngeli xesha kuya kuyimisa ukujikeleza kwamanzi, ukuze kuthintelwe ubushushu benjini yejenereyitha yedizili buphantsi kakhulu.
Itanki yamanzi yejenereyitha yedizili idlala indima ebaluleke kakhulu emzimbeni wonke wejenereyitha, ukuba itanki yamanzi ayisetyenziswanga kakuhle, iya kubangela umonakalo kwinjini yedizili nakwijenereyitha, kwaye iya kubangela ukuba injini yedizili ilahlwe kwiimeko ezinzima, ngoko ke, abasebenzisi kufuneka bafunde ukusebenzisa ngokuchanekileyo itanki yamanzi yejenereyitha yedizili.
