Uburyo moteri ya Diesel ikora
Inzira ya moteri ya mazutu ihindura ingufu zubushyuhe mu mbaraga za mashini igerwaho binyuze muburyo bune bukomeza: gufata, kwikuramo, akazi no kunanirwa. Buri nzira nkiyi yitwa cycle cycle. Moteri iyo ari yo yose irangiza inzinguzingo yo kuzenguruka inshuro ebyiri no gusubiza piston inshuro enye yitwa moteri ya bine. Ihame ryakazi rya moteri ya mazutu ane:
1. Fata inkorora
Crankshaft itwara piston kugirango yimuke kuva hejuru yapfuye ijya hagati yapfuye. Muri iki gihe, valve yo gufata irakinguye kandi na valve isohoka. Mugihe cyo kugenda kwa piston, ubwinshi bwa silinderi bwiyongera buhoro buhoro, bigakora icyuho, bityo imvange yaka yinjizwa muri silinderi ikoresheje valve yinjira kugeza piston igeze hepfo yapfuye hanyuma valve ifata.
Bitewe no kurwanya sisitemu yo gufata, umuvuduko wa gaze muri silinderi urangije gufata ni munsi yumuvuduko wikirere, hafi 0.075MPa ~ 0.09MPa. Bitewe no gushyushya ibice byubushyuhe bwo hejuru nkurukuta rwa silinderi na piston hamwe nubushyuhe bwo hejuru busigaye bwa gaze ya gaze isigaye mukwezi gushize, ubushyuhe bwa gaze burazamuka bugera kuri 370K ~ 440K. Icyinjira muri silinderi mugihe cyo gufata ntabwo ari imvange yaka, ahubwo ni umwuka mwiza.
2. Kwikubita hasi
Iyo impanuka yo gufata irangiye, piston yimuka ikava munsi yapfuye ikajya hagati yapfuye hejuru itwarwa na crankshaft, hanyuma ingano ya silinderi ikagabanuka buhoro buhoro. Muri iki gihe, imyuka yo gufata no gusohora irafunzwe, kandi umwuka mwiza urahagarikwa. Kwiyunvikana kurangira iyo piston igeze hejuru yapfuye. Mugihe cyo kwikuramo, umuvuduko wa gaze nubushyuhe byiyongera icyarimwe, kandi imvange irushijeho kuvangwa. Kubera ko igipimo cyo kwikuramo mazutu ari kinini, hafi 15 kugeza 22, ubushyuhe nigitutu nyuma yo kwikuramo birarenze, umuvuduko urashobora kugera kuri 3MPa kugeza 5MPa, kandi ubushyuhe bushobora kugera kuri 800K kugeza 1000K.
3. Gukubita ingufu
Iyo impanuka ya compression irangiye, pompe yatewe lisansi isuka mazutu yumuvuduko mwinshi mumazi yubushyuhe bwo hejuru hamwe numuyaga mwinshi mwinshi muri silinderi unyuze mumashanyarazi muburyo bwa gihu, bihita byuka kandi bigakora imvange hamwe na umwuka. Kubera ko ubushyuhe buri muri silindiri burenze ubushyuhe bwa auto-ignition ya mazutu (hafi 500K), ivangwa rya mazutu rihita ryaka kandi ryaka ryonyine, kandi mugihe runaka nyuma yaho, umuvuduko nubushyuhe muri silinderi bizamuka cyane mugihe utera inshinge lisansi, gusunika piston hepfo kugirango ukore akazi. Mugihe cy'amashanyarazi, umuvuduko mukanya urashobora kugera kuri 5MPa ~ 10MPa, naho ubushyuhe bwihuse burashobora kugera kuri 1800K ~ 2200K.
4. Umuvuduko ukabije
Iyo ingufu z'amashanyarazi ziri hafi kurangira, valve isohoka irakinguka, valve yinjira irafunga, hanyuma igikonjo gisunika piston kuva hagati yapfuye kugeza kuntambwe yapfuye ikoresheje inkoni ihuza. Umwuka wa gazi usohoka muri silinderi munsi yumuvuduko wacyo usigaye no gusunika piston. Iyo piston igeze hejuru yapfuye, valve isohoka irahagarara kandi umuyaga urangira. Kuberako hariho imyuka ihumanya muri sisitemu yo gusohora, iyo impanuka irangiye, umuvuduko uri muri silindiri urenze gato umuvuduko wikirere, hafi 0.105MPa ~ 0.115MPa, kandi ubushyuhe ni 900K ~ 1200K.
Muri izo nkoni enye, gusa ingufu z'amashanyarazi zitanga ingufu, naho izindi eshatu zose ni inkoni zifasha kwitegura gukubita amashanyarazi, kandi zose zitwara ingufu. Mubizunguruka byambere iyo moteri itangiye, hagomba kubaho imbaraga zo hanze zizunguruka igikonjo kugirango zuzuze gufata no kwikuramo. Iyo amashanyarazi atangiye, ingufu zakazi zibikwa muri flawheel zinyuze mumutwe kugirango bikomeze bikurikirane.
