DENSO ni umuyobozi ku isi mu ikoranabuhanga rya mazutu kandi mu 1991 ni cyo kintu cya mbere cy’umwimerere (OE) cyakoze amashanyarazi ya ceramic glow yamashanyarazi kandi kikaba icyambere muri sisitemu rusange ya gari ya moshi (CRS) mu 1995. Ubu buhanga bukomeje kwemerera uruganda gufasha abakora ibinyabiziga ku isi. gukora ibinyabiziga bigenda byitabira, bikora neza kandi byizewe.
Kimwe mu bintu by'ingenzi biranga CRS, yagize uruhare runini mu gutanga umusaruro ushimishije ujyanye nayo, ni uko ikorana na lisansi mu gitutu. Nkuko ikoranabuhanga ryahindutse kandi imikorere ya moteri igenda itera imbere, ni nako umuvuduko wa lisansi muri sisitemu wariyongereye, uva megapascal 120 (MPa) cyangwa akabari 1200 mugihe cyo gutangiza sisitemu yambere, kugeza kuri MPa 250 kuri sisitemu ya kane yubu. Kugaragaza ingaruka zikomeye iri terambere ryibisekuruza ryatanze, gukoresha lisansi ugereranije yagabanutseho 50%, ibyuka bihumanya byagabanutseho 90% naho ingufu za moteri ziyongeraho 120%, mugihe cyimyaka 18 hagati yicyiciro cya mbere nicya kane CRS.
Umuvuduko mwinshi wa pompe
Kugirango ukore neza kumuvuduko mwinshi, CRS yishingikiriza kubintu bitatu byingenzi: pompe ya lisansi, inshinge na electronics, kandi mubisanzwe ibyo byose byateye imbere hamwe na buri gisekuru. Noneho, pompe yumwimerere ya HP2 yakoreshejwe cyane cyane mugice cyimodoka zitwara abagenzi mumpera za 90, zanyuze mubishusho byinshi kugirango zibe verisiyo ya HP5 ikoreshwa uyumunsi, nyuma yimyaka 20. Ahanini itwarwa nubushobozi bwa moteri, iraboneka muburyo bumwe (HP5S) cyangwa silindiri ebyiri (HP5D), hamwe numubare wabyo usohoka ugenzurwa na valve ibanziriza kugenzura, ibyo bigatuma pompe ikomeza umuvuduko mwiza, waba cyangwa utabikora. moteri iri mu mutwaro. Kuruhande rwa pompe ya HP5 ikoreshwa mumodoka zitwara abagenzi hamwe n’ibinyabiziga bito by’ubucuruzi, ni HP6 kuri moteri ya litiro esheshatu kugeza kuri umunani na HP7 kubushobozi buri hejuru yibyo.
Ibitoro
Nubwo, uko ibisekuruza byagiye bisimburana, imikorere yatewe na lisansi ntabwo yahindutse, ubunini bwibikorwa byo gutanga lisansi bwateye imbere cyane, cyane cyane kubijyanye no gukwirakwiza no gukwirakwiza ibitonyanga bya peteroli mucyumba, kugirango bikongerwe neza. Ariko, nuburyo bagenzurwa bikomeza guhinduka cyane.
Mugihe isi yose igenda irushaho gukomera, inshinge zikoreshwa muburyo bwa mashini zahaye solenoid verisiyo ya electromagnetic igenzurwa, ikorana na elegitoroniki ihanitse kugirango itezimbere imikorere bityo igabanye ibyuka bihumanya. Nubwo, nkuko CRS yakomeje kugenda itera imbere, niko nuwatewe inshinge, kugirango agere ku bipimo bigezweho by’ibyuka bihumanya ikirere, igenzura ryabo ryagombaga kurushaho gusobanuka neza kandi gukenera gusubiza muri microsecond byabaye ngombwa. Ibi byatumye inshinge za Piezo zinjira murugamba.
Aho gushingira ku mikorere ya electromagnetic, izo inshinge zirimo kristu ya piezo, iyo, iyo ihuye numuyagankuba w'amashanyarazi, ikaguka, gusa igasubira mubunini bwambere uko isohoka. Uku kwaguka no kugabanuka bibera muri microseconds kandi inzira ihatira lisansi kuva inshinge mu cyumba. Bitewe nuko zishobora gukora byihuse, inshinge za Piezo zirashobora gutera inshinge nyinshi kuri silinderi hanyuma verisiyo ya solenoid ikora, munsi yumuvuduko mwinshi wa lisansi, bigatuma imikorere yaka umuriro ikomeza.
Ibyuma bya elegitoroniki
Ikintu cya nyuma nubuyobozi bwa elegitoronike yuburyo bwo gutera inshinge, bujyanye no gusesengura ibindi bipimo byinshi, bisanzwe bipimwa hifashishijwe icyuma cyerekana ingufu kugirango berekane igitutu mu biryo bya gari ya moshi bigenewe moteri ishinzwe kugenzura moteri (ECU). Nubwo, nubwo biteza imbere ikoranabuhanga, ibyuma byerekana ingufu za lisansi birashobora kunanirwa, bigatera kode yamakosa kandi, mubihe bikabije, kuzimya burundu. Kubera iyo mpamvu, DENSO yatangije ubundi buryo busobanutse bupima umuvuduko wa sisitemu yo gutera lisansi binyuze muri sensor yashyizwe muri buri inshinge.
Dushingiye kuri sisitemu yo kugenzura ifunze, DENSO's Intelligent - Accuracy Refinement Technology (i-ART) ni inshinge yo kwiyigisha yinjizwamo na microprocessor yayo, ikabasha kwihitiramo ubwigenge ubwinshi bwinshinge za lisansi nigihe cyagenwe kurwego rwiza kandi ikabimenyesha ibi amakuru kuri ECU. Ibi bituma bishoboka gukomeza gukurikirana no guhuza inshinge za lisansi kuri buri muriro kandi bivuze ko nayo yishyura ubuzima bwumurimo. i-ART ni iterambere DENSO itinjije gusa mu gisekuru cyayo cya kane cyatewe inshinge za Piezo, ahubwo yanatoranije solenoid ikora verisiyo yibisekuru bimwe.
Ihuriro ryumuvuduko mwinshi wo gutera inshinge na tekinoroji ya i-ART nintambwe ifasha cyane gukora moteri no kugabanya gukoresha ingufu, gutanga ibidukikije birambye no gutwara icyiciro gikurikira cyubwihindurize.
Inyuma
Imwe mu ngaruka zikomeye ku bihugu byigenga by’Uburayi ni uko, nubwo ibikoresho n’ubuhanga byo gusana biri gutezwa imbere ku muyoboro wemewe wo gusana DENSO, kuri ubu nta buryo bufatika bwo gusana pompe y’ibisasu bya kane cyangwa inshinge.
Kubwibyo, nubwo igisekuru cya kane CRS serivisi nogusana birashobora, kandi bigomba gukorwa, byakozwe numurenge wigenga, pompe ya lisansi cyangwa inshinge zananiwe ntibishobora gusanwa muri iki gihe, bigomba rero gusimburwa nibice bishya bihuye nubwiza bwa OE butangwa nababikora bazwi, nkibi nka DENSO.
