Izinjini zikadizili zingawonga kanjani uphethiloli?(二)
2021-08-20
Ukonga amafutha ezinjini zikadizili bekulokhu kuyingxenye ebalulekile yokonga izindleko, futhi kungathuthukisa ngempumelelo ukusebenza kahle nempilo yesevisi yezinjini zikadizili. Esihlokweni esandulele, sichaze amaphuzu amahlanu mayelana nezindlela zokonga uphethiloli we-diesel kanye nezindlela zokuphepha, futhi okulandelayo kusele, kanye nezindlela eziphumelela kakhulu.
6) Lungisa umfutho womjovo kaphethiloli womjovo kaphethiloli. Isibonelo, ingcindezi yomjovo kaphethiloli (12.0+0.05) MPa yesijovo sikaphethiloli senjini yedizili engu-195, lapho ingcindezi yomjovo kaphethiloli ingaphansi kuka-10.0MPa, ukusetshenziswa kukaphethiloli kuzokwenyuka ngo-10~20g/(kW. ), indlela yokuqhathanisa ingasetshenziswa ukuhlola nokulungisa ingcindezi yomjovo. Ukucindezela kwephampu kawoyela.
7) Hlola njalo futhi ugcine isici sokuhlunga umoya. Uma isici sokuhlunga umoya singcole kakhulu, ukungena komoya ngeke kwanele. Umphumela uyafana nomphumela ongalungile wokususwa kwe-valve. Kuzophinde kuholele ekunyukeni kokusetshenziswa kukaphethiloli kwenjini kadizili, ugesi onganele kanye nokungasebenzi kahle kwentuthu emnyama.
8) Uma injini ye-diesel isetshenziswa, zama ukuthi ungagijimi ngesivinini esiphezulu nomthwalo ogcwele ngangokunokwenzeka. Ngokuvamile, izinjini zikadizili zinebanga lokusebenza ukonga. Isivinini esilinganiselwe simakwe ku-nameplate yenjini, futhi ngokusho kokuhlaziywa kwejika lesici senjini ye-diesel, isivinini sokusebenza kwezomnotho okuhle kakhulu singama-85% wejubane elilinganiselwe. Ngalesi sikhathi, amandla/ihora ukusetshenziswa kukaphethiloli kuphansi kakhulu kulo lonke ibanga lesivinini. I-tachometer yenjini kadizili imakwe ngendawo eluhlaza, ngokuvamile okuyindawo yokusebenza kwezomnotho yenjini kadizili.
9) Ukulawula izinga lokushisa kwamanzi okupholisa. Ukushisa kwamanzi okuphansi kakhulu noma okuphezulu kakhulu kuzodala umonakalo omkhulu ezinjinini zikadizili. Lapho izinga lokushisa lamanzi liphansi kakhulu ngesikhathi sokusebenza, imvume ehambisanayo yezingxenye ezihambayo zenjini ye-diesel izoshintsha kakhulu kusukela ekuvunyelweni kokuklama, okuzokwandisa ukumelana nokugijima futhi kusheshise kakhulu ukuguga kwenjini ye-diesel. (Isibonelo, uma izinga lokushisa lamanzi lingaphansi kuka-30℃, lingaphezu kwezikhathi ezi-5 zokuguga okujwayelekile, okuzonyusa ukusetshenziswa kukaphethiloli ngo-15%). Uma izinga lokushisa lamanzi liphezulu kakhulu, lizokwenza injini ye-diesel ishise, ishintshe igebe lengxenye ngayinye, ibangele uchungechunge lwezinkinga ezifana nokwehla komfutho kawoyela, ukunamathela kwepiston kusilinda, ukwehla kwamandla, njll. Kunconywa ukuba gcina izinga lokushisa lamanzi ligijima ebangeni lika-80~90℃.
10) Faka idivayisi ye-diesel preheating enjini ye-diesel. Ukusebenzisa izinjini zedizili ebusika, ukuze wonge uwoyela futhi kuncishiswe ukusetshenziswa kwamandla, injini yedizili ishiswa ngaphambili ngepayipi lokukhipha umoya ukuze kwandiswe izinga lokushisa likadizili futhi kuncishiswe i-viscosity yedizili, ukuze idizili i-athomu futhi ishiswe ngokwanele. Lokhu kunganciphisa kakhulu ukusetshenziswa kukaphethiloli ngo-5% ~10%. Izinga lokushisa elingcono kakhulu lokushisisa kukadizili ngu-66~75℃, futhi umphumela ungcono kakhulu.
