Uma kukhona amaphutha ku- izinjiniesetshenziswa emibhoshongweni yokupholisa, lokhu kuzoba nomthelela omkhulu ekusetshenzisweni kwemibhoshongo yokupholisa. Ukuqinisekisa ukusetshenziswa okuvamile kwamamotho wokupholisa amamotho kuyisidingo esiyisisekelo sokuqinisekisa umphumela wokupholisa wemibhoshongo yokupholisa. Nakuba ukugcinwa kwezinjini zokupholisa akukwazi ukuqeda ukwehluleka kombhoshongo wokupholisa, kungadlala indima ebalulekile. Ngesikhathi sokusebenza kwemibhoshongo yokupholisa, umsindo wokupholisa ama-motor anikezelwe uphakeme kakhulu, okuyinkinga evamile. Ngaphezu kwalokho, imibhoshongo yokupholisa ngokuvamile isebenza ngaphansi kwezinga lokushisa eliphezulu nezimo eziphansi zomthwalo, ezinomswakama ophezulu wokusebenza nezindawo ezishisayo nezinomswakama, okuholela endaweni yokusebenza enzima kakhulu. Uma i-baffle isethwe ngaphansi kuka-10%, ipayipi lingadlidliza ngenxa yokucindezela okubi ngokweqile, ngaleyo ndlela kubeke engozini ukuphepha kokusebenza kwemishini. Ukuphepha komuntu siqu kanye nokuphepha kwemishini kubaluleke kakhulu kunoma iyiphi indawo.
Lapho umbhoshongo wokupholisa uqalwa ngokuqondile, isiqalo sombhoshongo wokupholisa sisikhulu, esingabangela isenzo sokuvikela umugqa ongenayo wegridi yamandla kagesi we-voltage ephezulu, futhi injini yokupholisa yombhoshongo ayikwazi ukuqaliswa ngokuqhubekayo. Lokhu kudinga amakhasimende ukuthi anake ngokugcwele amandla kagesi amanje futhi akalwe lapho eqala umbhoshongo wokupholisa onikezelwe iSimo.motor kagesi, ukuze injini iqale ngaphansi kwezimo ezijwayelekile. Ukusetshenziswa kwamandla kombhoshongo wokupholisa kukhulu, futhi ukusetshenziswa kwamandla kombhoshongo wokupholisa onikezelwe injini isikhathi ngasinye cishe usuku olulodwa lokusebenza okuvamile.
Ekusebenzeni okuvamile, lapho imbobo ye-baffle ingaphansi kuka-50%, ukulahlekelwa okuphawulekayo kokudonsa kanye nokulahlekelwa kwengcindezi yomoya kungase kwenzeke. Isixazululo sale nkinga siyinkimbinkimbi futhi sidinga abasebenzisi ukuthi basebenzise ulwazi oluthile olujwayelekile lukagesi. Yize kungezona zonke izinjini zokupholisa ezizoba nalezi zinkinga, eziningi zazo zivame ukudalwa ubudedengu bomsebenzisi weSimo Motor ngesikhathi sokusebenzisa. Ngakho-ke, noma ngabe umbhoshongo wokupholisa womsebenzisi unezinkinga ezingenhla noma cha, injini yokupholisa kufanele igcinwe ngesikhathi sokusetshenziswa ukuze kuqinisekiswe umphumela wokupholisa wombhoshongo wokupholisa.
