Ngenxa yokuthi umthamo othize wokushisa wamanzi mkhulu, izinga lokushisa liyakhuphuka ngemva kokumunca ukushisa kwe-cylinder block akukuningi, ngakho ukushisa kwenjini ngokusebenzisa isifunda samanzi okupholisa amanzi, ukusetshenziswa kwamanzi njengesiphathi sokushisa esithwala ukushisa, bese kuthi endaweni enkulu yosinki wokushisa ngendlela yokudlulisa ukushisa kwe-convection, ukuze kugcinwe izinga lokushisa elifanele lenjini ye-generator diesel.
Uma izinga lokushisa lamanzi enjini yokukhiqiza udizili liphezulu, iphampu yamanzi iphampa amanzi ngokuphindaphindiwe ukunciphisa izinga lokushisa lenjini, (Ithangi lamanzi lakhiwe ngeshubhu yethusi elingenalutho. Amanzi okushisa aphezulu angena ethangini lamanzi ngokupholisa komoya nokujikeleza odongeni lwesilinda senjini) ukuze kuvikelwe injini, uma izinga lokushisa lamanzi ebusika liphansi kakhulu, kulokhu, kuzomisa ukujikeleza kwe-generator yamanzi.
I-dizeli generator set water tank idlala indima ebaluleke kakhulu kuwo wonke umzimba we-generator, uma ithangi lamanzi lisetshenziswa ngendlela engafanele, lizodala umonakalo enjini ye-diesel kanye ne-generator, futhi lizokwenza ukuthi injini ye-diesel ikhishwe ezimweni ezimbi kakhulu, ngakho-ke, abasebenzisi kufanele bafunde ukusebenzisa kahle i-generator diesel set tank yamanzi.
