I-New Diesel Fuel Injector 320-0670 2645A733 Ye-CATERPILLAR PERKINS C6.6 ENGINE

Ukumodela Umjovo onesivinini esikhulu we-Diesel ICE(ingxenye 5）

Ngemva kwemiphumela yokubala, imidwebo itholwe njengoba kukhonjisiwe ku-fig.3 kanye fig.4. Idatha iqhathaniswa nenani lomthamo womjikelezo wesignali yokulawula efanayo, ngaphezu kwalokho, kufanele kucatshangelwe ukuthi umthamo ophezulu, impendulo esheshayo.

Kulandela imiphumela yezilinganiso ezinikezwe emidwebeni eku fig.3 kanye fig.4, isivinini sokusebenza komjovo senyukile ngokuphawulekayo.Mayelana nalokhu, ucwaningo olwengeziwe luzobandakanya ukuhlaziya umthelela wezinye izici nokuthuthukisa amanani azo ukuze kutholwe isivinini esikhulu sokusebenza.

3 Iziphetho

Ucwaningo olwengeziwe lokuthuthukisa ijubane lomjovo luzokwenziwa kusetshenziswa indlela echaziwe.Ukusebenza kahle kwenqubo kuzohlolwa ngemodi yokuvula yesikhashana esifushane yomjovo we-Bosch kanye nomjovo wesimanje.Umjovo wesimanje kufanele unikeze umthamo womjikelezo omncane ngezindlela zokuvula ngokugcwele isikhathi esifushane, kuyilapho kuzokwazi ukunciphisa isilinganiso somsebenzi phakathi kwemijovo.Ngokusekelwe emiphumeleni yokulingisa, kungaphethwa ngokuthi umthamo womjikelezo kufanele uncishiswe kumodi yokuvula egcwele yesikhathi esifushane, kuyilapho kuzokwazi ukunciphisa umjikelezo womsebenzi phakathi kwemijovo.Kulokhu, ucwaningo luzoqhutshekwa maqondana nazo zonke ezinye izici kanye nokwenza kahle kwamanani azo ukuze kutholwe isivinini esikhulu sokusebenza.

Okuthembisa kakhulu ekukhuphuleni isivinini sama-injector yile misebenzi elandelayo:

1) Ukuxhumana kwamandla asebenza enalitini ukuze kuncishiswe umzamo odingekayo we-electromagnetic.Lokhu kufanisa kuvumela ukusetshenziswa kwezizibuthe zikagesi ezinesivinini esiphezulu eziklanywe kahle kanye nemishini yazo yamandla kuma-injection asebenza kahle kakhulu.Okukhethekile kwale nqubo yokuhlanganisa ukuncika kwayo okubalulekile ezidingweni zokuqina, njengoba amandla okuvala inaliti eduze kwesihlalo, eqinisweni, angamandla abaliwe wedrayivu kagesi futhi angancishiswa kakhulu.Isibonelo, amandla we-valve yokulawula i-valve ye-solenoid ye-nozzle angancishiswa ngokuhleleka kobukhulu.

2) Ukuhlanganiswa kwe-elastic kwedrayivu enaliti.Lokhu kuxhumana kukuvumela ukuthi ufinyelele umphumela wokuphindaphinda, lapho ukushaywa kwezinaliti ezinkulu ngaphandle kokusebenzisa imishini yokudlulisa imishini noma ye-hydraulic kunikezwa ukunyakaza okuncane kwedrayivu kagesi.Ngesikhathi esifanayo, ukunciphisa ukusebenza kwe-stroke yanoma yiluphi uhlobo kuqinisekisa ukwanda kwejubane layo.3) Ukusetshenziswa kwemithombo yohlobo lwenduku.Iziphethu ezinjalo zinikeza izinga eliphezulu lokusebenziseka kahle kwezinto ekuqongeleleni amandla okuguqula.Iziphethu zenduku zihlinzeka ngamavelu amancane obuningi obunyakazayo futhi andise amathuba okuhlelwa kwama-injection.
