Chii chinonzi mota yeoiri yekudzora vharafu
Mota yeoiri yekudzora vharafu (OCV vharafu) chikamu chakakosha cheinjini yekuzora sisitimu, inonyanya kushandiswa kudzora nemazvo injini yevharuvhu uye kudzvanywa kwemafuta, kuitira kukwidziridza kuita kweinjini uye hupfumi hwemafuta.
Tsanangudzo uye basa
Ivhavha yekudzora mafuta (OCV valve) inonyanya kuumbwa nemuviri wevhavha (kusanganisira solenoid coil uye control module connector), slide valve uye chitubu chekudzoka. Nheyo yekushanda ndeye kudzora simba uye kudzima coil yemagetsi kuburikidza neiyo pulse modulation siginecha inopihwa neinjini control unit (ECU), uye wobva wagadzira magineti kudzora kuita kwevhavhavhavha inotsvedza, kuitira kuti urambe uchichinja hukama hwenguva pakati pe crankshaft necamshaft, kuti uwane yakanakisa valve phase control.
Nekugadzirisa uku, mavharuvhu ekudzora oiri anobatsira kuwedzera kushanda kweinjini, kunatsiridza kugadzikana, kuburitsa torque yakakura uye simba, ukuwo achivandudza hupfumi hwemafuta uye kuderedza kuburitswa.
Rudzi uye chimiro
Mafuta ekudzora mavharuvhu anogona kukamurwa kuita mapoka maviri: oiri regulator mavharuvhu uye ekudzivirira mavharuvhu. Basa guru rekumanikidza regulator nderekugadzirisa kudzvanywa muhurongwa kudzivirira kukuvadzwa kweiyo lubrication system nekuda kwekumanikidza kwakanyanya; Iyo yekudzivirira vharafu inoita basa mukutadza kweiyo pressure regulator kudzivirira iyo tubing kubva pakutyoka nekuda kwekudzvinyirira kwakanyanya.
Mukuwedzera, kune mafuta anodzvinyirira anodzora switch ane chekuita nedunhu. Kana kudzvinyirirwa kwemafuta kuchinge kusina kukwana, switch inovhara uye kukonzeresa yakaderera mafuta alarm mwenje pamudziyo wemotokari.
Nzvimbo uye kushandiswa
Iyo oiri yekudzora vharafu inowanzoiswa muhumburumbira chikamu cheinjini, iyo chaiyo chinzvimbo chiri kumashure kwecamshaft timing pulley pamativi ese, zvichiteerana nebasa rekutora uye kupera simba. Mavharuvhu aya ane cylindrical muchimiro uye ane plug kumusoro inobatanidza waya mbiri. Mukuwedzera, kune mamwe mavharuvhu anokosha ekudzora mafuta muhurongwa, sevhavha iri mumutumbi we cylinder, basa guru nderokugadzirisa kuyerera kwemafuta kune tile huru uye vvt; Imwe yacho inoshanda sevhavha yekudzorera mafuta kuona kuti mafuta anogona kudzoserwa pani yemafuta mushure mekunge mota yadzimwa.
Basa guru remotokari yekudzora oiri vharafu ndere kudzora nekudzivirira kudzvanywa kweinjini yekuzora sisitimu kubva pakunyanya kukwirira. Nekudzikamisa iyo yakanyanya kudzvanywa system, inodzivirira yakawandisa kudzvanya kubva mukukuvadza zvikamu zve lubrication system uye inodzivirira kubuda kwemafuta. Oil control valve inoumbwa nemusangano wemuviri uye actuator musangano, yakakamurwa kuita-seat-seat series,-seat-seat series, sleeve series uye self-propelled series yezvikamu zvina zvakatevedzana, imwe neimwe yakatevedzana ine kushandiswa kwayo kwakakosha, zvakanakira uye zvisingabatsiri pasi pemamiriro akasiyana ekushanda. ,
Basa chairo
Deredzai kudzvinyirira kwakanyanya kweiyo system : vharafu yekudzora mafuta nekugadzirisa kupihwa kwemafuta epombi yemafuta, kudzivirira kudzvanywa kwemafuta epombi yemafuta kwakanyanya, kunyanya nekumhanya kwakanyanya, kupihwa kwemafuta epombi yemafuta kwakakurisa, kudzvanywa kwemafuta kwakawedzera zvakanyanya, ipapo vharafu yekudzora oiri inonyanya kukosha.
Dzivirira kukuvadzwa kwemafuta ekuzora masisitimu : Kuwedzeredza kwemafuta kunogona kuita kuti hydraulic tasht valve ivhare zvisizvo, cylinder pressure idonhe, uye inogona kutokonzera kuti tubing iparare. Iyo oiri control valve inodzivirira iyo lubrication system kubva mukukuvadzwa nekugadzirisa kudzvanywa.
Inochengetedza kushanda kwakanaka uye kwakadzikama kweinjini : mune inoshanduka vharafu retiming injini, iyo oiri yekudzora vharafu inovimbisa kugadziridzwa kwechikamu checamshaft nekudzora nemazvo shanduko yemafuta nzira, kuitira kuti ive nechokwadi chekuti injini inogona kuwana yakanakisa kushanda mamiriro pasi pemamiriro akasiyana ekushanda.
Fault effect
Kana iyo valve yekudzora mafuta ikatadza, inogona kuita kuti mota imire panguva yekutyaira, uye kudzvanywa kwemafuta kunokwira zvisina kujairika, kunokanganisa kushanda kwemotokari, senge musanganiswa wakanyanya kukora, utsi hwakasviba kubva papombi yekuburitsa, uye simba rinopera simba. Kuwedzerwa kwemafuta ekumanikidza kunogonawo kukonzera kuwedzera kushandiswa kwemafuta, kubuda kwemhepo yakawandisa, uye kusagadzikana kumhanyisa kumhanya, kuwedzera njodzi dzekuchengetedza uye mutoro wehupfumi wemotokari. Nokudaro, kana vhavha yekudzora mafuta ichionekwa kuti haina kunaka, inofanira kugadziriswa pakarepo.
