Izahlulo ze-Auto ze-Diesel Engine Nozzle DN0PDN121 Fuel Injector Nozzle

ULondolozo lweMibhobho yesitofu seDizili (icandelo 1)

Imilomo yesitofu se-injini ye-diesel inoxanduva lokuzisa isixa esifanelekileyo samafutha kwisilinda ngasinye somthwalo kunye nemfuno yamandla ehashe. Ebudeni bobomi be-injini, inani leziganeko zokutofa linokufikelela kwiibhiliyoni, kwaye mhlawumbi iitriliyoni. Ukongeza, imilomo yesitofu iphantsi kobume bendawo exhaphaza kakhulu-ngaphezu kwayo nayiphi na enye indawo ye-injini. Imilomo ihlala kwindawo yokutshisa i-injini ye-diesel kwaye ibonakaliswe kwiqondo lokushisa elingaphezu kwe-1,800 degrees, ngelixa uxinzelelo lwangaphakathi lunokugqithisa i-30,000 psi.

Nangona phantse wonke umenzi wenkqubo yamafutha ecebisa ukuba kusetyenziswe imilomo, ezi nkqubo zihlala zingahoywa ngumnini-injini kwaye zisonjululwa kuphela xa kukho ingxaki. Ulondolozo lothintelo kufuneka lube yinxalenye yesicwangciso somnini ngamnye we-injini ye-diesel ukuba ubomi obude kunye nokusebenza okungenazinkathazo kuyafunwa.

Ukubonisa abafundi boMbane weDiesel kumanyathelo afunekayo okubonelela ngemilomo yesitofu yoomatshini, sityelele neMack Boring & Parts Company eManyano, eNew Jersey. Ukungabinabudlelwane neelori zeMack, iMack Boring ayithengisi iinjini zedizili ezintsha kuphela, ikwakha kwakhona iinjini zedizili kwaye inikezela ngenkonzo epheleleyo yenkqubo yamafutha kuninzi lwezicelo zedizili.

IGqirha leNkampani ye-Mack Boring & Parts kwivenkile yamafutha kwivenkile ephezulu nguFrank Pakay. Uyinxalenye yesebe lenkonzo kaMack Boring, elilawulwa nguMike Alfano, apho imilomo yedizili neempompo zenaliti zinikwa iinkonzo kubathengi kwilizwe jikelele ngenxa yodumo lwale venkile kunye nembali ende yokusebenza ngeenjini zedizili kuphela.

Ngelixa i-Diesel Power yayikwi-Mack Boring, isethi yee-injection ezininzi ze-orifice yayilungiselelwa inkonzo. Bezisuka kwi-440hp Yanmar 6LY2A-STP turbocharged six-cylinder marine engine. Isikhalazo somthengi esenze ukuba ii-injector zisuswe yingxelo yomsi oluhlaza/omnyama ngokungenzi nto. Eminye imiba eqhelekileyo ehlala ikhomba imfuneko yenkonzo yokutofa kukungenzi nto okanye ukuvutha komlilo, ukusetyenziswa kwepetroli ngokugqithisileyo, ukuqala kanzima, kunye nokusilela kokusebenza ngokubanzi. Nangona i-injini ye-Yanmar isebenzisa uyilo lwayo lombhobho, ifana kakhulu nento enokufunyanwa kwi-injini ye-Cummins enenkqubo yamafutha ematshini.
