Ikigega cyo gufata amavuta cyangwa gufata amavuta birashobora kuba igikoresho cyashyizwe muri sisitemu ya cam / crankcase ihumeka kumodoka. Gushiraho ikigega cyo gufata amavuta (gishobora) kigamije kugabanya umubare wumwuka wamavuta wongeye kuzenguruka mu gufata moteri.
Guhumeka neza
Mugihe gikora gisanzwe cya moteri yimodoka, imyuka imwe ivuye muri silinderi inyura kumpeta ya piston ikamanuka mukibanza. Hatabayeho guhumeka ibi birashobora kotsa igitutu kandi bigatera ibibazo nko kubura kashe ya piston hamwe na kashe ya peteroli yangiritse.
Kugira ngo wirinde ibi, ababikora bakoze sisitemu yo guhumeka. Ubusanzwe ibi wasangaga akenshi byari shingiro ryibanze aho hashyizwemo akayunguruzo hejuru yikibaho cya kamera hanyuma igitutu hamwe numwuka bihumeka mukirere. Ibi byafatwaga nk'ibitemewe kuko byemereraga imyotsi n'ibicu bya peteroli gusohoka mu kirere byateje umwanda. Irashobora kandi guteza ibibazo abari mu modoka kuko ishobora gukururwa imbere yimodoka, akenshi idashimishije.
Ahagana mu 1961, hashyizweho igishushanyo gishya. Igishushanyo cyahinduye umwuka uhumeka mu gufata imodoka. Ibi bivuze ko imyuka hamwe nigicu cyamavuta bishobora gutwikwa no kwirukanwa mumodoka binyuze mumuriro. Ntabwo ibyo byari bishimishije cyane kubari bafite imodoka byasobanuraga kandi ko igihu cya peteroli kitarekuwe mu kirere cyangwa ku muhanda mu bijyanye na sisitemu yo guhumeka.
Ibibazo biterwa no gufata inzira ihumeka
Hano haribibazo bibiri bishobora guterwa no guhinduranya umwuka uhumeka muri sisitemu yo gufata moteri.
Ikibazo nyamukuru nukwiyubaka kwa peteroli imbere mu gufata no gufata ibintu byinshi. Mugihe gikora cya moteri isanzwe ihumeka cyane hamwe na peteroli ziva mumavuta ya crank biremewe kwinjira muri sisitemu yo gufata. Igicu cyamavuta arakonja kandi agashyira imbere imbere yo gufata imiyoboro myinshi. Igihe kirenze iki cyiciro gishobora kwiyubaka kandi umwanda mwinshi urashobora kwegeranya.
Ibi byarushijeho kuba bibi hashyizweho uburyo bwa gaze ya gaze ya gaze (EGR) ku modoka zigezweho. Imyuka ya peteroli irashobora kuvanga hamwe na gaze yongeye gusohora gaze hamwe na soot hanyuma ikiyubaka kuri feri ya feri na valve nibindi. Uru rupapuro mugihe gikomera kandi rukabyimba inshuro nyinshi. Ihita itangira gufunga umubiri wa trottle, flaps flaps, cyangwa na valve yo gufata kuri moteri yatewe.
Kugira ubwinshi bwa silige birashobora gutera imikorere mike bitewe ningaruka zigabanya bigira kumyuka kuri moteri. Niba kwiyubaka birenze urugero kumubiri bishobora gutera kudakora neza kuko bishobora guhagarika umwuka mugihe isahani ya trottle ifunze.
Gushyira ikigega gifata (gishobora) kugabanya umubare wumwuka wamavuta ugera munzira zifata nicyumba cyaka. Hatariho umwuka wamavuta soot iva muri valve ya EGR ntishobora guhurira cyane kubyo gufata bizarinda gufata gufata.
