Ngenxa yokuthi amandla okushisa athile amanzi makhulu, ukukhuphuka kwezinga lokushisa ngemva kokumunca ukushisa kwe-cylinder block akukuningi, ngakho ukushisa kwenjini ngokusebenzisa isekethe yamanzi apholile, ukusetshenziswa kwamanzi njengesithwali sokushisa, bese kudlula endaweni enkulu yesinki sokushisa ngendlela yokushabalalisa ukushisa kwe-convection, ukuze kugcinwe izinga lokushisa elifanele lokusebenza kwenjini yejenereyitha kadizili.
Uma izinga lokushisa lamanzi lenjini yejenereyitha likadizili liphezulu, iphampu yamanzi ipompa amanzi ngokuphindaphindiwe ukuze inciphise izinga lokushisa lenjini, (Ithangi lamanzi lakhiwe ngepayipi lethusi elingenalutho. Amanzi okushisa aphezulu angena ethangini lamanzi ngokupholisa komoya kanye nokugeleza komoya odongeni lwesilinda senjini) ukuvikela injini, uma izinga lokushisa lamanzi asebusika liphansi kakhulu, kulokhu kuzomisa ukujikeleza kwamanzi, ukuze kugwenywe izinga lokushisa lenjini yejenereyitha likadizili liphansi kakhulu.
Ithangi lamanzi lesethi yejenereyitha yedizili lidlala indima ebaluleke kakhulu emzimbeni wonke wejenereyitha, uma ithangi lamanzi lisetshenziswa ngendlela engafanele, lizobangela umonakalo enjinini yedizili kanye nejenereyitha, futhi lizobangela nokuthi injini yedizili ilahlwe ezimweni ezimbi kakhulu, ngakho-ke, abasebenzisi kumele bafunde ukusebenzisa kahle ithangi lamanzi lesethi yejenereyitha yedizili.
