Urebye ibintu biranga imyanya yo kwicara, nyuma yubushakashatsi, ingero yimikorere yingirakamaro yo guterura inshinge ya valve yakozwe, kandi ugereranije nuburinganire buringaniye. Binyuze murukurikirane rwubushakashatsi bwubushakashatsi hamwe nisesengura rya teoretiki, imyanzuro yafashwe niyi ikurikira: ugereranije na leta ihagaze, umuvuduko wo gufungura imbaraga za valve y'urushinge uri hejuru cyane, ariko igitutu cyo gufunga imbaraga ni gito, ibyo bikaba bifitanye isano rya bugufi. imikorere ya moteri. Kubera ko inshinge ya inshinge ifite ibiranga kwicara bifite imbaraga, byongera kandi diameter yikururwa ryamavuta mugice cyanyuma cyo gutera inshinge, bityo bikagabanya ubwiza bwa spray, ndetse bikanagabanya ubuzima bwamavuta ya peteroli, bikabangamira icyerekezo cyuka . Muburyo bwo gushira inshinge zifatanije inshinge, bitewe nibidukikije bikaze cyane, hejuru ya cone ikunze kwambara no kurira. Impamvu iterwa numwanda uva mumavuta ningufu zingaruka zatewe mugihe valve yinshinge yicaye. Nyuma yo kwambara no kurira, bizatera ihinduka ryimiterere ya cone ifunze, byongere ubukana bwubuso, bigabanye cyane ingaruka zo gufunga, kandi binanirwa gutanga ingaruka nziza yo gutera. Ikirenzeho, gutonyanga amavuta bizabaho, kandi amavuta ya mazutu ntashobora gutwikwa byuzuye. Mu cyumba cyo gutwika, umwobo wo gutera inshinge n'ibice bikonje bikonje, havamo imyuka myinshi ya karubone, bikaviramo kuziba umwobo. Mu kurangiza, ingufu za moteri ya mazutu yagabanutse cyane, bituma hakoreshwa peteroli yihariye.
