I-Diesel Fuel Injector Remanufactured 10r-7673 Cat 320-0690 for Caterpillar 928h 928Hz 930h 938h Cat Engine C6.6

Kukho iimeko apho i-plane ye-drop point iphezulu, ingathathi hlangothi kwaye iphantsi. Xa kumiselwa lo mphakamo, kufuneka kuqwalaselwe into yokuba isiphelo sombhobho siphuma kwinqwelomoya esezantsi yentloko yesilinda 2 ~ ~ 3mm. Kwakhona kunokwenzeka ukumisela ubude bendawo yokulahla inqwelomoya kwigumbi lokutsha, kwaye emva koko unqume i-Angle ye-cone phakathi kwemingxuma yejethi.

Ubume, umthamo, umlinganiselo we-caliber kunye ne-diameter-depth ratio yegumbi lokutsha kwintloko yepiston inxulumene nokumisela ukuqhelaniswa komlomo ngamnye. Ngokomzekelo, xa kuthelekiswa ne-combustor yomlomo ojikelezayo we-O-type, iprojekti ye-nozzle orientation ye-nozzle nganye kumphezulu ophezulu we-piston kunye ne-Angle phakathi kwamacala amane omlomo wesikwere kuneemfuno ezithile. Kwangaxeshanye, le Angle inxulumene ngokusondeleyo nolwalathiso lokuhamba komoya kwigumbi lokutsha.

Isiseko sejometri yoyilo lwemingxuma yejethi

Njengoko kukhankanywe ngaphambili, le jet cone inesaphetha esihle esifakwe phakathi kwe-G ukuya kwisohlwayo sesigaba okanye i-square yomlomo we-O-uhlobo lwegumbi lokutsha. I-axis ye-jet cone kunye ne-intersection ye-axes ezimbini). Igumbi lokutsha kumphezulu wepiston lidla ngokuba ligumbi elingqukuva okanye elisisikwere. I-axis ye-jet cone kunye

I-axis yegumbi lokutsha kwi-piston top kunye ne-axis ye-cylinder ifomu i-Angle efakiwe. Ngokomthetho wegrafu ye-quadratic equation, i-cone yeyegrafu ye-quadratic equation, nayiphi na indiza kunye nesangqa esingahambelani ne-axis ye-cone okanye ibhasi. Ukusika kwesigaba, umfanekiso wayo ojikelezileyo yi-ellipse.
