Izizathu nezisombululo zokukhipha intuthu engajwayelekile yezinjini zikadizili zeCaterpillar (intuthu emnyama)

2022-04-06

Izimbangela kanye nokuqedwa kwentuthu emnyama Lo mkhuba ubangelwa ukushiswa kukaphethiloli okungaphelele. Uma kukhishwa intuthu emnyama, kuvame ukuhambisana nokwehla kwamandla enjini, izinga lokushisa eliphezulu le- exhaust, nezinga lokushisa eliphezulu lamanzi, okuzoholela ekugugekeni kwezingxenye zenjini futhi kunciphise ukuphila kwenjini.

Izimbangela zalesi simo (ziningi izimbangela zokuvutha okungaphelele) nezindlela zokuqeda zimi kanje:

1) I-exhaust back pressure iphezulu kakhulu noma ipayipi le-exhaust livinjiwe. Lesi simo sizobangela ukungena komoya okwanele, ngaleyo ndlela kuthinte isilinganiso sokuxuba amafutha omoya, okuholela kuphethiloli oweqile. Lesi simo senzeka: Okokuqala, ukugoba kwepayipi yokukhipha, ikakhulukazi ukugoba kwe-90 ° kuningi kakhulu, okufanele kuncishiswe; okwesibili ukuthi ingaphakathi le-muffler livinjwe umule omningi futhi kufanele likhishwe.

2) Umoya onganele wokungena noma ipayipi elivalekile lokungena. Ukuze uthole isizathu, ukuhlolwa okulandelayo kufanele kwenziwe: okokuqala, ukuthi ngabe isihlungi somoya sivinjiwe; okwesibili, kungakhathaliseki ukuthi ipayipi lokungenisa liyavuza (uma lokhu kwenzeka, injini izohambisana nekhwelo elinzima ngenxa yokwanda komthwalo); okwesithathu Ukuthi i-turbocharger yonakele yini, hlola ukuthi izindwani zesondo legesi ephumayo kanye nesondo le-supercharger zonakele yini nokuthi ukujikeleza kushelela futhi kuyaguquguquka; okwesine ukuthi i-intercooler ivinjiwe.

3) I-valve clearance ayilungiswanga kahle, futhi umugqa wokuvala ama-valve awuxhumene kahle. Ukususwa kwama-valve, iziphethu ze-valve, nama-valve seal kufanele kubhekwe.

I-4) Ukunikezwa kwamafutha kwesilinda ngasinye sepompo yamafutha okucindezela okuphezulu akulingani noma kukhulu kakhulu. Ukunikezwa kukawoyela okungalingani kuzodala isivinini esingazinzile kanye nentuthu emnyama. Kufanele ilungiswe ukuze ilingane noma ibe phakathi kwebanga elishiwo.

5) Uma umjovo kaphethiloli uphuzile, i-engeli yangaphambi kwesikhathi yomjovo kaphethiloli kufanele ilungiswe.

I-6) Uma i-injector ye-fuel ingasebenzi kahle noma yonakalisiwe, kufanele isuswe ukuze ihlanzwe futhi ihlolwe.

7) Ukukhetha imodeli yomjovo akulungile. Izinjini ezinesivinini esikhulu ezingenisiwe zinezidingo eziqinile kuzijovo ezikhethiwe (imbobo yomjovo, inombolo yezimbobo, i-engeli yomjovo). (Lapho amandla okukhiphayo, isivinini, njll. ehlukile), amamodeli omjovo adingekayo ahlukile. Uma ukukhetha kungalungile, uhlobo olulungile lomjovo kaphethiloli kufanele kushintshwe.

8) Izinga likadizili liphansi noma izinga alilungile. Injini kadizili enesivinini esiphezulu ephuma kwamanye amazwe efakwe negumbi elivuthayo lomjovo womjovo onezimbobo eziningi inezidingo eziqinile zekhwalithi kanye nebanga likadizili ngenxa yembobo encane kanye nokunemba okuphezulu komjovo. Injini ayisebenzi kahle. Ngakho-ke, amafutha e-diesel ahlanzekile futhi afanelekayo kufanele asetshenziswe. Kunconywa ukusebenzisa inombolo 0 noma +10 ehlobo, -10 noma -20 ebusika, futhi -35 ezindaweni ezibandayo kakhulu.

9) I-cylinder liner kanye ne-piston components zigqokwe kakhulu. Uma lokhu kwenzeka, indandatho ye-piston ayivalwa ngokuqinile, futhi umfutho womoya kusilinda wehla kakhulu, okubangela ukuthi uwoyela kadizili ungashi ngokuphelele futhi ukhiphe intuthu emnyama, namandla enjini ehle kakhulu. Ezimweni ezimbi kakhulu, injini izocisha ngokuzenzakalelayo lapho ilayishiwe. Izingxenye zokugqoka kufanele zishintshwe.
