Imikorere yo gukubita imodoka
Imikorere yingenzi ya sensor sensor yimodoka ni ukumenya gukomanga kuri moteri, no gukumira gukomanga uhindura Angle avance ya Angle, kugirango urinde moteri kwangirika.
Rukuruzi ya knock ihindura ihindagurika ryimashini ya moteri mubimenyetso byamashanyarazi byoherezwa mubice bishinzwe kugenzura ibikoresho bya elegitoronike (ECU). ECU ihindura inkongi y'umuriro ikurikije ibimenyetso byakiriwe kugirango wirinde gukomeza guturika. Sensor ya knock isanzwe ikoresha tekinoroji ya ceramic ya piezoelectric. Iyo moteri ihinda umushyitsi, ceramic irahagarikwa kandi igahinduka kugirango itange ibimenyetso byamashanyarazi, byoherezwa muri ECU binyuze mumugozi ukingiwe kugirango ubitunganyirize.
Ihame ryakazi rya knock sensor rishingiye ku ngaruka za piezoelectric, iyo moteri ikomanze, ceramics ya piezoelectric ceramics imbere muri sensor irakanda, itanga ikimenyetso cyamashanyarazi. Ibi bimenyetso byoherejwe muri ECU, ihindura Angle avance ya Angle ishingiye kumibare yabitswe kugirango irinde gukomanga. Mubyongeyeho, gukubita sensor birashobora kumva umuvuduko numwanya wa moteri, bitanga amakuru menshi yo gufasha kunoza imikorere ya moteri.
Sensor ya knock isanzwe ishyirwa ahantu runaka muri moteri ya moteri, nko hagati ya silindiri 2 na 3 ya mashini ya silindari enye cyangwa hagati ya silinderi 1 na 2 na silindari 3 cyangwa 4. Umwanya wacyo wo gushiraho ufata ibyiyumvo byoroheje bya moteri yinyeganyeza no gukomanga.
Niba icyuma gikomanga cyananiranye, nubwo kitazatera moteri kunanirwa gutangira, bizatera ibibazo nka moteri ya moteri, gutakaza ingufu, ubukungu bwifashe nabi, n'amatara yamakosa. Kubwibyo, imikorere ikwiye ya knock sensor ningirakamaro kumikorere ya moteri.
Automotive knock sensor ni igikoresho cyashyizwe kuri moteri ya moteri, ikoreshwa cyane cyane mukumenya gukomanga kwa moteri. Hariho ubwoko bwinshi bwa sensor sensor, ibisanzwe muri byo harimo magnetostrictive na piezoelectric ceramic.
Ubwoko nuburyo bwa knock sensor
Magnetostrictive : igizwe na rukuruzi ya rukuruzi, rukuruzi ihoraho hamwe na coil induction. Iyo moteri ihinda umushyitsi, ingirabuzimafatizo ya magneti irahinduka, bikavamo ihinduka ryimikorere ya magnetiki muri coil induction, bikavamo imbaraga za electronique .
piezoelectric ceramic : Iyo moteri ihinda umushyitsi, ceramic imbere iranyeganyezwa kugirango itange ikimenyetso cyamashanyarazi. Kuberako ibimenyetso bidakomeye, umugozi wihuza mubisanzwe uzengurutswe ninsinga ikingiwe .
piezoelectric resonance : yashyizwe mugice cyo hejuru cyumubiri wa moteri, gukoresha imbaraga za piezoelectric kugirango uhindure ibinyeganyezwa bya mashini mubimenyetso byamashanyarazi. Iyo gukomanga gukubita inshuro bihuye ninshuro karemano ya sensor, hazabaho kubaho resonance, kandi voltage yo hejuru ya knock signal izasohoka muri ECU, ukurikije ECU izahindura igihe cyo gutwika kugirango wirinde gukomanga .
Uburyo bwo gukomanga bukora
Gukubita sensor yumva kunyeganyega n'amajwi ya moteri ikabihindura mubimenyetso by'amashanyarazi byoherejwe mubice bigenzura moteri (ECU). ECU ihindura imirishyo yimbere ya Angle ukurikije ibimenyetso byakiriwe kugirango ikumire guturika. Ihame ryihariye ryakazi niryo rikurikira:
Magnetostrictive : kunyeganyega kwa moteri bitera imbaraga za magneti guhinduka, guhindura ibintu bya rukuruzi muri coil induction, bikavamo imbaraga za electronique .
piezoelectric ceramic : iyo moteri ihinda umushyitsi, ceramic ya piezoelectric ceramic iranyeganyezwa kugirango ikore ibimenyetso byamashanyarazi, ECU ihindura igihe cyo gutwika ukurikije ibimenyetso.
Ubwoko bwa piezoelectric resonance ubwoko : iyo gukomanga gukomanga gukubita bihuye ninshuro karemano ya sensor, ibintu bya resonance bibaho, kandi ibimenyetso byerekana imbaraga za knock byasohotse muri ECU.
Uruhare rwo gukomanga mumodoka
Igikorwa nyamukuru cya knock sensor ni ugupima jitter ya moteri. Iyo moteri itanga gukomanga, ibimenyetso byamashanyarazi byoherezwa muri ECU, hanyuma ECU igahindura imirishyo yimbere kugirango ikumire. Gukomanga birashobora kwangiza moteri, bityo sensor ya knock igira uruhare runini mukurinda moteri .
