I-Diesel Injector Fuel Injector 0445110484 Bosch for Deutz

Izitofu zamafutha ngamacandelo amancinane ombane asetyenziselwa ukuhambisa isibaso ngesitshizi ngokuthe ngqo kwindawo eninzi yokungena phambi kwevalve yokungena kwi-injini yedizili.Izitofu zedizili zintsonkothile kakhulu;I-injector ine-micron filter ephezulu kwicala lokungena eliphezulu elihambelana nemingxuma emincinci yobungakanani be-hypodermic emazantsi ukwenzela ukuba i-atomizing ye-diesel fuel.I-diesel fuel isebenza njengomthombo wokuthambisa kumalungu angaphakathi e-injector.Umthombo oyintloko wokungaphumeleli kwii-injection ngamanzi kumafutha.Xa amanzi kumafutha ehambisa iipropati zokuthambisa iindawo zangaphakathi ziguga ngokukhawuleza kwaye i-injector iyonke inokusilela ngokukhawuleza.

Izitofu ziyinxalenye ye-injini ebaluleke kakhulu.Ivalve yesitofu iyavula kwaye ivale nge-rpm efanayo nenjini yedizili.I-RPM eqhelekileyo yeenjini zedizili kuMntla Melika imalunga ne-1800. Oku kulingana namaxesha angama-140,000 ngeyure!Ukongeza kumanzi kwi-fuel, ii-injection ziphantsi kwekhabhoni kunye neengqungquthela zokungcola ezifakwe kwiyunithi ngokusebenzisa into embi yokucoca umoya.Uhlobo lwepetroli, ibakala kunye nezongezo ezisetyenzisiweyo nazo zinempembelelo enkulu kwixesha elilindelekileyo lokuphila kwi-injector yamafutha.I-ECM (Imodyuli yoLawulo lwe-Injini) ilawula ii-injector zamafutha kwiinjini ezininzi ze-diesel zombane.Izitofu zedizili zihlala zinamandla xa isitshixo sivulwa kungakhathaliseki ukuba injini ijikwe.I-ECM ibeka i-injector, igqibezela isiphaluka kwaye ibangela ukuba i-nozzle ye-injector ivuleke.I-ECM emva kokufumana ulwazi oluvela kwii-sensors zolawulo ezahlukeneyo inquma ubude bexesha ii-injection kufuneka zibekwe phantsi ukuze zifake inani elichanekileyo lepetroli elinikwe imfuno yokuphuma kwamandla eenjini.

Inkqubo yezitofu zedizili yokuvula, ukuvala kunye nokukhupha isixa esichanekileyo samafutha kwenzeka kwiimilliseconds.Ukudubula umjikelo we-injector ku-avareji kugqitywe kwi-1.5 ukuya kwi-5 milliseconds.Izitofu zamafutha edizili ziza ngeemilo ezahlukeneyo kunye nobukhulu ngokuxhomekeke kwi-injini yokwenza kunye nemodeli kunye nemfuno yamandla.Ii-injection zeemoto zincinci kakhulu kune-dizeli enzima kwaye zilinganiswa ngee-intshi ze-cubic.Kukho iindidi ezimbini zezitofu ze-diesel fuel: eyokuqala ibizwa ngokuba yi-throttle body injection apho ii-injection ezi-1-2 zifumaneka kumzimba we-throttle ngokwawo kwi-injini ye-diesel kwaye zibonelela ngemitha ye-mist spray spray kwi-manifold intake.Le nkqubo yonikezelo ihlawulisa umthamo kunye nevalve yokuthatha itsalela amafutha kwicylinder yenjini.Inkqubo yesibini yonikezelo, eyaziwa ngokuba sisitofu sohlobo lwezibuko lomntu ngamnye, intsha kwaye iyonga kakhulu amafutha.Uhlobo lwezibuko lwenaliti lusebenza ngakumbi kune-carburetor kuba lulungelelanisa ukuxinana komoya kunye nokuphakama kwaye aluxhomekekanga kwisingxobo esininzi.

Ukungasebenzi kakuhle kwesitofu sokutshiza kuvela xa iisilinda zikufutshane kwii-injection ezinomxube ongcono kunezo zikude.Ngohlobo lwezibuko lwesitofu esi siphako siyapheliswa ngokutofa umlinganiselo ofanayo wamafutha kwi-cylinder nganye kwi-injini.
