Izinjini zikadizili zingawonga kanjani uphethiloli? (一)

Uma injini ye-diesel ingasebenzi kahle, kungakhathaliseki ukuthi ingakanani ukungasebenzi kahle, izonciphisa ukusebenza kahle kwenjini ye-diesel futhi ikhulise ukusetshenziswa kukaphethiloli. Ngakho-ke, ukugcinwa okujulile kwenjini ye-diesel, futhi inkinga kufanele ilungiswe ngokushesha, ingenye yezindlela eziphumelelayo zokunciphisa ukusetshenziswa kwamafutha enjini ye-diesel (ukusetshenziswa kukaphethiloli nokusetshenziswa kwamafutha). Ukwenza injini ye-diesel isebenze ngendlela eyonga uphethiloli, amaphuzu alandelayo adinga ukwenziwa.
1) Ukugcina isimo esingcono kakhulu se-valve yenjini ye-diesel kungenye yezinto eziyisisekelo zokonga uphethiloli wenjini ye-diesel. i-air coefficient yenjini ye-diesel, okuholela ekushisweni kukaphethiloli okungaphelele. Ngenxa yalokho, hhayi kuphela ukuntuleka kwamandla enjini ye-diesel, ukubonakala kwentuthu emnyama nokunye ukwehluleka kokusebenza, kodwa futhi nokwanda okukhulu kokusetshenziswa kukaphethiloli. Ngakho-ke, kuyadingeka ukuhlola imvume ye-valve njalo.
2) Gcina i-engeli ehamba phambili yokunikezwa kukaphethiloli kusengaphambili. Isibonelo, i-engeli engcono kakhulu ye-engeli yokunikezwa kwangaphambili kukaphethiloli yenjini ye-diesel engu-195 ingu-16°~20°.Lapho injini kadizili isetshenziswa isikhathi esithile, ngenxa yokuguga kwezixhumo ze-plunger nezingxenye zokudlulisela zomjovo kaphethiloli. iphampu, i-engeli yokunikezwa kukaphethiloli kusengaphambili izokwehla, okubangele ukuthi isikhathi sokunikezwa kukaphethiloli siphuze kakhulu, futhi ukusetshenziswa kukaphethiloli kukhuphuke. Ngakho-ke, kuyadingeka ukuqinisekisa ukuthi i-engeli yokunikezwa kukaphethiloli isendaweni engcono kakhulu.
3) Gwema ukuvuza kwamafutha enjini ye-diesel. Kukhona ukuvuza kukawoyela noma ukuvuza kukawoyela ohlelweni lukaphethiloli. Nakuba kungase kungabi kubi kakhulu, kuzodala ukulahlekelwa okukhulu kukaphethiloli ngokuhamba kwesikhathi.
4)Qinisekisa ukuthi ukuhlanganiswa kwesilinda kuhlala kusesimweni esihle kakhulu sokusebenza. Uma izingxenye ze-cylinder zigqokwa, ukucindezela kokucindezela kwe-cylinder kuzokwehla, okuzoholela nakanjani ekubhebhethekeni kwemvelo yokushisa uphethiloli, okuzokwandisa kakhulu ukusetshenziswa kukaphethiloli.
5)Shintsha indlela "yenqola enkulu edonsa amahhashi". Imishini eminingi ine "umshini omkhulu onomthwalo omncane, okuwukumosha amandla. Indlela yokuthuthukisa: ukwandisa ngokufanele i-pulley yenjini ye-diesel, futhi ukhulise isivinini semishini lapho injini ye-diesel isebenza ngesivinini esincishisiwe, ukuze kuzuzwe inhloso yokwanda kwamandla nokonga amandla.
