DENSO ndi mtsogoleri wapadziko lonse muukadaulo wa dizilo ndipo mu 1991 anali woyamba zida zoyambirira (OE) wopanga mapulagi a ceramic glow ndipo adachita upainiya wa njanji wamba (CRS) mu 1995. ukatswiri uwu ukupitilizabe kulola kampaniyo kuthandiza opanga magalimoto padziko lonse lapansi. kupanga magalimoto omvera, ogwira ntchito komanso odalirika.
Chimodzi mwazinthu zazikulu za CRS, zomwe zatenga gawo lalikulu popereka zopindulitsa zomwe zimagwirizanitsidwa nazo, ndikuti zimagwira ntchito ndi mafuta opanikizika. Monga ukadaulo wasintha komanso magwiridwe antchito a injini akuyenda bwino, momwemonso kukakamiza kwamafuta m'dongosolo kukukulirakulira, kuchokera ku 120 megapascals (MPa) kapena 1,200 bar pakukhazikitsa dongosolo la m'badwo woyamba, mpaka 250 MPa padongosolo lamakono lachinayi. Kuwonetsa kukhudzika komwe kwabwera chifukwa chakukula kumeneku, kugwiritsa ntchito mafuta kwatsika ndi 50%, kutsika kwamafuta kumatsika ndi 90% ndipo mphamvu ya injini yakwera ndi 120%, pazaka 18 pakati pa CRS ya m'badwo woyamba ndi wachinayi.
Mapampu Amafuta Othamanga Kwambiri
Kuti agwire bwino ntchito pazitseko zazikulu zotere, CRS imadalira zinthu zitatu zofunika: pampu yamafuta, majekeseni ndi zamagetsi, ndipo mwachilengedwe zonsezi zapangidwa ndi m'badwo uliwonse. Chifukwa chake, mapampu oyambira amafuta a HP2 omwe amagwiritsidwa ntchito makamaka pamagalimoto onyamula anthu kumapeto kwa zaka za m'ma 1990, adadutsamo zingapo kuti akhale mitundu ya HP5 yomwe imagwiritsidwa ntchito masiku ano, zaka 20 pambuyo pake. Zoyendetsedwa kwambiri ndi mphamvu ya injini, zimapezeka mumitundu imodzi (HP5S) kapena iwiri ya cylinder (HP5D), ndikutulutsa kwawo komwe kumayendetsedwa ndi valavu yowongolera isanachitike, zomwe zimatsimikizira kuti mpope imakhalabe ndi mphamvu yake yabwino, kaya kapena ayi. injini ili pansi pa katundu. Pambali pa mpope wa HP5 womwe umagwiritsidwa ntchito pamagalimoto onyamula anthu ndi magalimoto ang'onoang'ono ogulitsa, pali HP6 yamainjini asanu ndi limodzi mpaka asanu ndi atatu ndi HP7 yamphamvu kuposa pamenepo.
Mafuta opangira mafuta
Ngakhale, m'mibadwo yonse, ntchito ya jekeseni ya mafuta siinasinthe, zovuta za njira yoperekera mafuta zakula kwambiri, makamaka pankhani ya kufalikira ndi kufalikira kwa madontho a mafuta m'chipindamo, kuti apititse patsogolo kuyaka bwino. Komabe, ndimomwe amalamuliridwa ndi zomwe zikupitilira kusintha kwakukulu.
Pamene miyezo yapadziko lonse lapansi yotulutsa mpweya imachulukirachulukira, majekeseni amakina adalowa m'malo mwa mitundu yamagetsi yoyendetsedwa ndi solenoid, yogwira ntchito ndi zida zamagetsi zapamwamba kuti ziwongolere magwiridwe antchito ake ndikuchepetsa kutulutsa. Komabe, monga CRS ikupitilira kusinthika, momwemonso jekeseni, kuti akwaniritse miyezo yaposachedwa yotulutsa mpweya, kuwongolera kwawo kudayenera kukhala kolondola kwambiri ndipo kufunikira koyankha mu ma microseconds kumakhala kofunikira. Izi zapangitsa kuti ma jekeseni a Piezo alowe mumkangano.
M'malo modalira mphamvu zamagetsi zamagetsi, majekeseniwa amakhala ndi makristasi a piezo, omwe, akakhala ndi mphamvu yamagetsi, amakula, ndikungobwereranso kukula kwake koyambirira pamene akutuluka. Kukula ndi kutsika uku kumachitika mu ma microseconds ndipo njirayo imakakamiza mafuta kuchokera ku jekeseni kupita kuchipinda. Chifukwa chakuti amatha kuchitapo kanthu mwachangu, majekeseni a Piezo amatha kubaya jakisoni wochulukirapo pa silinda ya silinda ndiye kuti solenoid adamulowetsa Baibulo, pansi pa mphamvu yamafuta apamwamba, zomwe zimathandizira kuyaka bwino kwambiri.
Zamagetsi
Chinthu chomaliza ndi kasamalidwe kamagetsi ka njira ya jakisoni, yomwe pambali pa kuwunika kwa magawo ena ambiri, mwachizolowezi amayezedwa pogwiritsa ntchito sensor yokakamiza kuti iwonetse kupanikizika mu chakudya cha njanji yamafuta kupita kugawo lowongolera injini (ECU). Komabe, ngakhale akupanga ukadaulo, masensa amafuta amafuta amatha kulephera, zomwe zimapangitsa kuti pakhale zolakwika ndipo, zikavuta kwambiri, kuzimitsa kwathunthu. Zotsatira zake, DENSO idachita upainiya njira ina yolondola kwambiri yomwe imayesa kukakamiza kwa jakisoni wamafuta kudzera pa sensa yomwe imayikidwa mu jekeseni iliyonse.
Kutengera makina owongolera otsekeka, DENSO's Intelligent-Accuracy Refinement Technology (i-ART) ndi jekeseni yodziphunzirira yokha yokhala ndi microprocessor yake, yomwe imathandiza kuti izitha kusinthiratu kuchuluka kwa jakisoni wamafuta ndi nthawi yake kuti ikhale yoyenera komanso kuyankhulana ndi izi. Zambiri za ECU. Izi zimapangitsa kuti zizitha kuyang'anira mosalekeza ndikusintha jakisoni wamafuta pa kuyaka kwa silinda iliyonse ndipo kumatanthauza kuti imadzipiritsanso pa moyo wake wautumiki. i-ART ndi chitukuko chomwe DENSO sichinaphatikizepo m'badwo wake wachinayi wa Piezo injectors, komanso kusankha solenoid activated versions of the same generation.
Kuphatikizika kwa ukadaulo wapamwamba wa jakisoni ndiukadaulo wa i-ART ndikupambana komwe kumathandizira kukulitsa magwiridwe antchito a injini ndikuchepetsa kugwiritsa ntchito mphamvu, kupereka malo okhazikika ndikuyendetsa gawo lotsatira la chisinthiko cha dizilo.
The Aftermarket
Chimodzi mwazofunikira kwambiri pamalonda odziyimira pawokha a ku Europe ndikuti, ngakhale zida zokonzera ndi njira zikukonzekera ma netiweki ovomerezeka a DENSO, pakali pano palibe njira yokonzekera yokonza mapampu amafuta am'badwo wachinayi kapena majekeseni.
Chifukwa chake, ngakhale kuti ntchito ndi kukonza kwa m'badwo wachinayi wa CRS zitha, ndipo ziyenera kuchitidwa ndi gawo lodziyimira palokha, mapampu amafuta kapena majekeseni omwe alephera pakali pano sangathe kukonzedwa, kotero ayenera kusinthidwa ndi magawo atsopano ofananira ndi OE omwe amaperekedwa ndi opanga odziwika bwino. ngati DENSO.
