Igikoresho cyo gukata imodoka ni iki?
Imashini ihindura ikirere mu modoka, ubusanzwe yerekeza ku gihindura ikirere muri sisitemu yo gupima igihe cy’ingufu zihinduka (VVT), ni igice cy'ingenzi mu buryo bw’ingufu za moteri. Ikoreshwa mu guhindura mu buryo burambuye igihe cyo gufungura no gufunga cy’ingufu zinjira cyangwa zisohora umwuka kugira ngo moteri irusheho gukora neza, ikoreshe neza lisansi, ndetse n’ingano y’ibyuka bihumanya mu bihe bitandukanye by’imikorere.
Inshingano yayo y'ingenzi ni uguhindura inguni y'icyiciro kiri hagati ya camshaft na crankshaft hashingiwe ku miterere y'igihe nyacyo nko kwihuta kwa moteri, umutwaro, n'ubushyuhe, bityo bigatuma igihe cy'ingufu zihindagurika gihoraho. Moteri zifite igihe cy'ingufu zihoraho ntizishobora kuringaniza imbaraga z'umuvuduko muto n'umuvuduko mwinshi, mu gihe ihinduranya ry'icyiciro, binyuze mu guhindura neza, rituma moteri igera ku buryo bwiza bwo kwinjiza no gusohora umwuka mu buryo butandukanye.
Ibisobanuro bigufi by'amahame y'imikorere
Ubusanzwe icyuma gihindura imiterere y'imashini gishyirwa ku mpera y'imbere ya camshaft kigahuzwa n'urunigi rw'igihe cyangwa pulley. Imiterere yacyo y'ibanze igizwe na rotor ifatanye neza na camshaft na stator ifatanye na pulley y'igihe. Uruhererekane rw'ibice by'amavuta bifunze hagati ya rotor na stator rukorwa.
Ihinduranya ry'ingufu rya Hydraulic phase (rikomeye): Amavuta ya moteri, munsi y'umuvuduko wa pompe y'amavuta, agezwa neza mu cyumba cyo hejuru cyangwa cyo hasi cya phase hinduranya binyuze muri valve igenzura amavuta (valve ya OCV). Mu kugenzura umuvuduko wa peteroli, rotor izenguruka ugereranije na stator, bityo igahindura phase ya camshaft. Urugero, gutanga amavuta mu cyumba cyo hejuru bishobora gutuma valve ifungura kare kugira ngo yongere torque yihuta cyane; gutanga amavuta mu cyumba cyo hasi bishobora gutinza gufungura valve kugira ngo yongere imbaraga zihuta cyane.
Ihinduranya ry'amashanyarazi (ikoranabuhanga rigezweho): Urugero, ihinduranya ry'amashanyarazi ryakozwe na LuK rikoresha imiterere ya mechanical ifite umurongo wa gatatu uyoborwa na moteri, ihuza neza camshaft, pulley, na moteri. Mu kugenzura neza umuvuduko wa moteri, izunguruka hagati ya camshaft na pulley igerwaho, bityo igahindura igihe cy'ingufu. Iyi miterere ntishingiye ku muvuduko w'amavuta ya moteri, ifite umuvuduko wihuta wo gusubiza, ifite ubushobozi bwo kugenzura neza, kandi ntigira ingaruka ku bushyuhe buke bwa peteroli ya moteri.
Ibyiza by'ingenzi
• Ongera imbaraga zisohoka: Ongera inguni ihuza valve ku muvuduko wo hejuru wa moteri, wongere ingano y'ingufu, kandi wongere imbaraga za moteri.
• Kunoza uburyo lisansi ikoreshwa: Kugera ku ngaruka za Miller cycle utinza gufunga valve y'injira ku mutwaro muke, bigabanye igihombo cyo kuvoma.
• Kugabanya imyuka ihumanya: Gutwika neza bigabanya imyuka yangiza (nka CO, NOx, na HC).
• Kongera ubushobozi bwo guhuza n'ikirere: Cyane cyane icyuma gihindura ikirere gikoresha amashanyarazi, gifite ubushobozi bwo guhuza n'ubushyuhe bwa moteri n'imiterere yayo.
Gusobanura kutumvikana gusanzwe
• Ishusho y'icyiciro ≠: Ishusho y'icyiciro niyo ikora, ishinzwe "guhindura"; mu gihe ifoto y'icyiciro (nk'ifoto y'aho camshaft iherereye) ari yo ikora, ishinzwe "gukurikirana" aho camshaft iherereye no gusubiza ikimenyetso ku gice gigenzura moteri (ECU) kugira ngo habeho uburyo bwo kugenzura bufunze.
• Phase shifter ≠ camshaft variable phase controller: Iri jambo rya nyuma ni ijambo rikoreshwa n'ibigo nka Audi ku ngamba zabo zo kugenzura sisitemu ya VVT, kandi igice cyayo cy'ingenzi ni phase shifter.
Muri make, ikoranabuhanga ryo guhindura imodoka mu buryo bwa phase ni rimwe mu ikoranabuhanga ry’ingenzi kuri moteri zigezweho kugira ngo zigere ku mikorere myiza, isukuye kandi ikora neza. Iterambere ryaryo ririmo kuva ku bwoko bwa hydraulic busanzwe kugeza ku bwoko bw’amashanyarazi bunoze kandi bwizewe.
Mu rwego rw'ibinyabiziga, ijambo "phase shifter" rikunze kuvuga ibice bibiri bitandukanye by'imikorere, kandi imikorere yabyo yihariye iterwa na sisitemu ikoreshwamo.
• Ihindagurika ry’ingufu za VVT (sisteme ihindagurika ya valve): Iki ni igice cy'ingenzi mu buryo bw'imicungire ya moteri. Inshingano yayo y'ingenzi ni uguhindura uburyo camshaft izenguruka ishingiye ku mikorere nyayo ya moteri (nk'umuvuduko n'umutwaro). Mu guhindura igihe cyo gufungura no gufunga kwa valve zo gusohora umwuka, ishobora kunoza uburyo bwo kwinjira no gutwika muri silinda, ikagera ku ngaruka zo kongera ingufu za moteri, kunoza uburyo lisansi ikoreshwa, no kugabanya imyuka ihumanya. Igenzura ry'ingufu z'imodoka (igenzura amashanyarazi): Iki gice gifite inshingano zo kugenzura no kugenzura ingufu z'amashanyarazi zisohoka muri moteri. Bitewe n'impinduka mu muvuduko wa moteri, umuvuduko wa moteri urahindagurika, ibyo bigatuma ingufu z'amashanyarazi zisohoka zidahindagurika. Igenzura ry'amashanyarazi rigenzura ingufu z'amashanyarazi ziri muri moteri kugira ngo rirebe ko ingufu z'amashanyarazi zisohoka ziguma zihamye ku giciro cyagenwe (ubusanzwe hafi 14.0V). Ibi birinda neza ibikoresho by'amashanyarazi biri mu bwato ihindagurika ry'amashanyarazi kandi bifite inshingano zo gukumira ingufu z'amashanyarazi zikabije no guca ingufu z'amashanyarazi zisubira inyuma (isubira inyuma) kugira ngo birinde bateri na moteri.
