ihame ry'imikorere

1.Icyuma cya ogisijeni ni iboneza risanzwe mu modoka. Nibintu bipima bikoresha ceramic sensibilité yo gupima ubushobozi bwa ogisijeni mu miyoboro isohora ibinyabiziga, kandi ikabara ubunini bwa ogisijeni ikurikije ihame ry’uburinganire bw’imiti, kugira ngo ikurikirane kandi igenzure igipimo cy’ibicanwa biva mu kirere no kwemeza ibicuruzwa ubuziranenge hamwe n’ibisohoka byujuje ubuziranenge. Oxygene sensor ikoreshwa cyane mugucunga ikirere cyo gutwika amakara atandukanye, gutwika amavuta, gutwika gaze nandi matanura. Nuburyo bwiza bwo gupima ikirere cyaka muri iki gihe, kandi gifite ibyiza byuburyo bworoshye, igisubizo cyihuse, kubungabunga byoroshye, gukoresha neza no gupima neza. Gukoresha iki cyuma kugirango upime kandi ugenzure ikirere cyaka ntigishobora gusa guhagarara neza no kuzamura ubwiza bwibicuruzwa, ariko kandi bigabanya umuvuduko wumusaruro no kuzigama ingufu.

2.Ihame ryakazi rya sensor ya ogisijeni mumodoka irasa na bateri yumye, kandi element ya zirconia muri sensor ikora nka electrolyte. Ihame ryibanze ryakazi ni: mubihe bimwe, itandukaniro rishobora guterwa no gukoresha itandukaniro rya ogisijeni hagati yimbere na hanze ya zirconi, kandi uko itandukaniro ryinshi ryibanze, niko itandukaniro rishobora kuba ryinshi. Ibiri muri ogisijeni mu kirere ni 21%, kandi gaze isohoka nyuma yo gutwika imvange ikungahaye mu byukuri nta ogisijeni ihari. Umwuka wa gaze nyuma yo kuvanga ibinure cyangwa gaze ya gaze kubera kubura umuriro urimo ogisijeni nyinshi, ariko iracyari munsi ya ogisijeni mu kirere. Munsi ya catalizike ya platine mubushyuhe bwinshi, ion ya ogisijeni yuzuye nabi irashirwa kumurongo wimbere ninyuma ya zirconia. Kubera ko mu kirere hari umwuka wa ogisijeni mwinshi kuruta muri gaze ya gaze, uruhande ruvugana n’ikirere ku isanduku rwinjiza ioni nyinshi kuruta iyo ku ruhande rwa gaze ya gaze, kandi itandukaniro ry’imiterere ya ion ku mpande zombi ritanga ingufu z'amashanyarazi.

3.Iyo umwuka wa ogisijeni uri kuruhande rwa gaze ya gaze ya gaze yimodoka iba mike, hakorwa ingufu nyinshi (0,6 ~ 1V) hagati ya electrode ya sensor ya ogisijeni, kandi iki kimenyetso cya voltage cyoherejwe mumodoka ECU kugirango yongerwe imbaraga. ECU ifata ibimenyetso bya voltage ndende nkumuvange ukungahaye hamwe nikimenyetso cya voltage nkeya nkivanga rinini. Ukurikije ibimenyetso bya voltage ya sensor ya ogisijeni, mudasobwa igabanya cyangwa ikungahaza imvange ukurikije igipimo cyiza cya peteroli yo mu kirere hafi ya 14.7: 1. Kubwibyo rero, sensor ya ogisijeni ni sensor yingenzi yo kugenzura ibipimo bya peteroli. Gusa iyo sensor ya ogisijeni iri mubushyuhe bwinshi (iherezo igera kuri 300 ° C) irashobora kuranga neza kandi voltage irashobora gusohoka. Hafi ya 800 ° C, ifite igisubizo cyihuse ku ihinduka ry’imvange, ariko ibi biranga bizahinduka cyane ku bushyuhe buke.
