Mhepo yakawanda mita inoshanda sei uye nei uchifanira kuitarisira?
Zviri mukati
Iyo mita yekuyerera kwemhepo inorongwa sei uye chii chinoputika mairi?
Iwe unofungei - chii chiyero chemusanganiswa wemafuta nemhepo? Parita yega yega mafuta, kune 14,7 kg yemhepo, iyo inopa anopfuura 12 XNUMX malita. Saka mutsauko wakakura, zvinoreva kuti zvakaoma kudzora injini kuitira kuti ive neyakaringana kuumbwa kwemusanganiswa unopiwa kune injini. Iyo yese process inodzorwa ne processor iri mune inonzi injini ECU. Zvichienderana nezviratidzo zvakagamuchirwa kubva kuma sensors, inoita jekiseni metering, throttle kuvhura uye zvimwe zvakawanda zviito zvinokanganisa kushanda kweinjini yekupisa yemukati.
Mhando dzemamita ekuyerera mukati meinjini dzinopisa
Nekufamba kwemakore, michina iyi yakawedzera kuve yakarurama uye yakavimbika. Parizvino kune marudzi matatu emaflowmeters ari kushandiswa:
● vharafu;
● guru;
● ultrasonic.
Iyo petal flow mita inorongwa sei?
Mhepo yakadaro inoyerera mita yakashandiswa mumagadzirirwo ekare. Iyo ine dampers (saka zita) rakabatana nemhepo sensor uye potentiometer. Pasi pesimba rekutsauswa kwevhavha, iyo inomanikidzwa kupikisa mhepo, iyo voltage ye potentiometer inoshanduka. Kuwanda kwemhepo inosvika pahuwandu hwekutora, inoderedza voltage uye zvakasiyana. Iyo damper mita ine zvakare yekunzvenga kubvumira injini kusashanda kana damper ichivharira kuyerera kwemhepo.
Chii chinonzi air mass mita uye inoshanda sei?
Iyi idhizaini yakawedzera magetsi kana ichienzaniswa neye damper mita. Inosanganisira chiteshi chinopfuura nemhepo, waya inopisa uye unit yekupisa. Ehe, mudziyo unosanganisirawo kutonga zvemagetsi uye masensa anotumira chiratidzo kune komputa. Yakadaro mota yemhepo inoyerera mita inoyera kuyerera kwemhepo yakawanda. Izvi zvinoitwa uchishandisa waya yeplatinamu, iyo inochengetwa patembiricha yenguva dzose inosvika 120-130°C. Kutenda kune yakareruka dhizaini uye yakakwirira kushanda zvakanaka, flowmeters yerudzi urwu hairegi simba rezvishandiso zvinopisa uye haigadziri kupikisa kwemhepo.
Ultrasonic kuyerera mita mumotokari
Iyi ndiyo yakanyanya kuomesesa yekuyera kuyerera kwemhepo. Mwoyo wemudziyo uyu ijenareta revibration rinokonzera kubvongodzwa kwemhepo kwezvimiro zvakasiyana zvichienderana nehuwandu hwemhepo. Kudedera kunotorwa nemaikorofoni, iyo inobva yatumira chiratidzo kune transducer inoita masvomhu. Iyi mita yekuyerera kwemhepo ndiyo yakanyanya kurongeka, asi kuti uwane mibairo chaiyo, yakakura yekuyera sisitimu uye kuongororwa kwemhedzisiro inodiwa.
Mhepo misa mita - nei ichityora?
Iwe unotoziva kuti mita yekuyerera chii uye kuti inoshanda sei, asi nei ichitadza? Chekutanga, damper mhando hadzina kupikisa zvakanyanya kushanda zvisina kunaka kwekugadzika gasi. Iyo damper mu flowmeter inokurumidza kuvhara pasi pechiito chekudzokera shure uye inokuvadza.
Kusvibiswa kwemhepo ndiro dambudziko rinowanzoitika mumidziyo yakawanda. Nokudaro, dambudziko rinosanganiswa nemafungiro asina hanya ekushanda, somuenzaniso, kushayikwa kwekugara kuchinjwa kwesefa yemhepo. Mhedzisiro yacho inogona zvakare kuve conical mitambo sefa inopa kudhonza kushoma uye kuita zvirinani, asi kana ikashandiswa zvisizvo, haiteye zvinosvibisa zvakawanda sefirita yepepa.
Air mass mita - zviratidzo zvekukuvara
Dambudziko riri nyore remhepo misa mita yekuongorora kurasikirwa kwesimba reinjini. Hwaro husina kunaka hwekuyerera kwemhepo hunoendeswa kune inodzora injini, iyo inogadzira dosi yemafuta inogadziriswa nechiratidzo, uye kwete nehuwandu chaihwo hwemagasi akayamwa mukamuri yekupisa. Naizvozvo, mota inogona kunge isina simba, semuenzaniso, mune yakaderera injini yekumhanyisa renji.
Nzira yekutarisa kana mita yemhepo yakakura yakakuvadzwa?
Nzira yekutarisa sei kuyerera kwemamita mumotokari? Nzira iri nyore ndeyekubatanidza mota kune yekuongororwa interface kana kutsvaga mota yakafanana pakati peshamwari uye gadzirisazve kuyerera mita kubva kune imwe kuenda kune imwe. Kuchenesa mita yekuyerera kunokurudzirwawo kuti iwedzere kudiwa kwemafuta uye kuumbwa kwakashata kwegasi.
Nzira yekuchenesa sei mita yekuyerera mumotokari?
Usashandise mvura kune izvi! Zvakanakisisa kushandisa gadziriro yepfapfaidzo uye kuchenesa mota yekuyerera mita navo. Mirira kuti mushonga upere zvachose. Kana tsvina yakawanda yakaungana pairi, ongororawo throttle muviri uye uchenese kana zvichidikanwa.
Kuyerera kwemhepo kuyerwa masisitimu anogona kubatsira zvakanyanya kushanda kweinjini yekupisa mukati. Kushanda kwakaringana kwemamita ekuyerera kwakakosha zvakanyanya, nekuti kana paine matambudziko nechinhu ichi, pachava nekudonha kwekuita kweinjini. Kuongorora mamiriro ayo uye kuchenesa mabasa anofanirwa kuitwa kana zviratidzo zvinotyisa zvichionekwa.
