I-low-temperature corrosion yi-sulphur dioxide kanye ne-sulfur trioxide ekhiqizwa yisibabule kuphethiloli ngesikhathi senqubo yokusha kusilinda, okubili okungamagesi, ahlangana namanzi ukuze kukhiqizwe i-hyposulfuric acid ne-sulfuric acid (lapho izinga lokushisa lodonga lwesilinda aphansi kunendawo yawo yamazolo), ngaleyo ndlela enze ukugqwala okunezinga lokushisa eliphansi. .
Uma ingqikithi yenombolo yesisekelo sawoyela wesilinda iphansi kakhulu, amadiphozithi afana nopende azovela ebusweni bomugqa wesilinda phakathi kwendawo ngayinye yokujova uwoyela, futhi ingaphezulu le-cylinder liner ngaphansi kwento efana nopende lizofiphazwa ukugqwala. . Uma kusetshenziswa ama-cylinder liners ane-chrome, izindawo ezimhlophe (i-chromium sulfate) zizovela ezindaweni ezigqwalile.
Izinto ezithinta ukugqwala kwezinga lokushisa eliphansi okuqukethwe kwesibabule kuwoyela kaphethiloli, inani le-alkali kanye nezinga lomjovo kawoyela kuwoyela wesilinda, kanye nokuqukethwe kwamanzi kwegesi yokukhipha udoti. Umswakamo womoya okhipha udoti uhlobene nomswakama womoya kanye nezinga lokushisa lomoya okhipha udoti.
Lapho umkhumbi uhamba endaweni yasolwandle enomswakama ophezulu, qaphela ukuhlola ukuphuma kwamanzi ajiyile esipholile somoya.
Ukusethwa kwezinga lokushisa lokumpompa kunokubili. Ukushisa okuphansi kungadlala indima "yokupholisa okomile", umswakama ohlobene nomoya wokulahla uzokwehla, futhi amandla enjini eyinhloko azokhula; kodwa-ke, izinga lokushisa eliphansi lokukhipha umoya lizothinta izinga lokushisa lodonga lwesilinda. Uma izinga lokushisa lodonga lwesilinda liphansi kunephuzu lamazolo, ukugqwala okuphansi kwezinga lokushisa kuzokwenzeka lapho inani eliyisisekelo lefilimu kawoyela yesilinda odongeni lwesilinda linganele.
Kushiwo kusiyingi yesevisi yenjini eyinhloko ukuthi uma injini enkulu isebenza ngomthwalo ophansi, kutuswa ukuba kwandiswe izinga lokushisa elifanele ukuze kugwenywe ukugqwala okuphansi kwezinga lokushisa.
Ukuze kwandiswe izinga lokushisa kwamanzi okupholisa amasilinda enjini eyinhloko ukuze kuncishiswe ukugqwala kwezinga lokushisa eliphansi, i-MAN isebenzise uhlelo lwe-LCDL ukukhulisa amanzi okupholisa amasilinda enjini amakhulu abe ngu-120 °C ukuvimbela ukugqwala kwezinga lokushisa eliphansi.
