I-Diesel Injector Fuel Injector 0445120149 Bosch for Longgong855 Forklift Engine Weichai Wd10

Isiphumo se-Double Injector kwiNkqubo yokuTsha kwi-396 Series ye-Diesel Engine (icandelo lesi-5)

Xa i-injector ye-8-hole yamkelwe, impembelelo yokunciphisa umgama wokungena kwinkqubo yokutshisa iqiniswe, indawo yokusabalalisa i-fuel iyonke kunye nokutshiswa kwangaphambili okuxutywayo kuyancitshiswa, kwaye ukutshiswa kwe-diffusion kuyancitshiswa, ngaloo ndlela kwenza ukutsha kungagqibekanga kwaye ukusebenza kakuhle kwe-thermal kuphantsi.Emva kokuba i-4-hole i-double-injector yamkelwe, njengoko ii-injection ezimbini zihlukaniswe ngumgama othile, indawo yokusabalalisa indawo ye-fuel iyanda, kwaye umphumo wokuxuba phakathi kwe-fuel spray kunye nomoya kwi-cylinder uqiniswa.

Nangona umgama wokungena usemfutshane kwaye ukutsha okuxutywe kwangaphambili kusengaphantsi kwe-5-hole injector, ukukhutshwa kobushushu obuqokelelweyo bulingana ne-5-hole injector kuba umoya okwi-cylinder usetyenziswa ngokupheleleyo, ukutsha. Ubude bexesha lokutsha kosasazo lude kancinane kwaye ukutshiswa kugqibelele.Umzobo we-5 ubonisa ukuba, xa i-injector ye-8-hole yamkelwe, ukutshisa akuphelelanga, uxinzelelo lokutshisa kunye nobushushu obuphakathi kwi-cylinder kunye nokukhutshwa kwe-NO kuphantsi.Xa i-4- hole i-double-injector yamkelwe, ukukhutshwa kwe-NO malunga ne-60% ye-injector ye-5-hole ngenxa yeqondo lokushisa eliphantsi lokutsha.

4 Iziphumo zokulinganisa kunye nohlalutyo lokunciphisa ixesha lokutofa kwe-4-hole dual-injector

Ngaphantsi kwemeko yokuba ubude be-injection kunye nommandla wokuhamba osebenzayo awutshintshi, ukusebenza kakuhle kwe-thermal kuyancipha xa uguqula i-injector ye-5-hole kwi-injector ye-8-hole.Nangona kunjalo, ukuba i-4-hole-double-injector yamkelwe, ukusebenza kakuhle kwe-thermal kugcinwa kufana ne-5-hole injector.Ukuba ukunyanzeliswa kwe-injection kunyuswa, ixesha lokutofa liyancitshiswa kwaye umgama wokungenwa kwe-oyile ye-oyile uyanda, ukuxutywa kwepetroli kunye nomoya kunyuswa ngakumbi kwaye inkqubo yokutshisa iyaphuculwa.Umzobo 6, uMzobo 7 kunye noMzobo 8 ngokulandelanayo ubonisa uxinzelelo kwi-cylinder, izinga lokukhutshwa kobushushu, ubushushu obuphakathi kwi-cylinder, ukukhutshwa kobushushu obuqokelelweyo kunye ne-NO mass fraction xa i-angle ye-injection ye-4-hole dual-injector yi-26.84 ° CA, 22 ° I-CA kunye ne-20 ° CA.
