Diesel Injector Fuel Injector 0445120151 Bosch for Ko-Matsu PC200-8 PC210-8 SAA6d107e-1 Engine Cummins Industrial Engines

Mhedzisiro yeDouble Injector pane Combustion process mune 396 Series Diesel Injini (chikamu6)

Mufananidzo 6, Mufananidzo 7 uye Figure 8 inoratidza kuti, kana nguva yejekiseni ikapfupikiswa, kupisa.

nguva yekunonoka inopfupiswa zvishoma uye nzvimbo yekutanga yekupisa inofambiswa. Iyo yakakwira iyo peak combustion kupisa kuburitsa mwero, ndiko kutanga kwechikamu chinoenderana. Kana iyo yakanyanya kupisa kudzvanywa kwakawedzera, chikamu chinoenderana chinofambiswa. Kana yakakwira avhareji tembiricha mucylinder, chikamu chinowirirana chinofambiswa mberi asi avhareji tembiricha mucylinder panguva yekupedzisira yekupisa inoderedzwa zvishoma. Kupisa kunopisa kusunungurwa kunowedzera, iyo yakaunganidzwa kupisa kusunungurwa kwakangofanana, asi NO emission inowedzera zvakanyanya.13

Sezvo nzvimbo yekutanga jekiseni inochengetedzwa pa 352 ° CA, nenguva pfupi yejekiseni, iyo mafuta

yakapfapfaidzwa muhumburumbira inowedzerwa kuburikidza neayo crank angle uye chinhambwe chinopinda chinowedzerwa.14 Izvi zvinotungamira kune kuwanda kwemafuta kusanganiswa nemhepo uye nani mafuta atomization, saka nguva yekunonoka yekudzima inopfupiswa, kupisa kwemafuta kwakasanganiswa kusati kwaitwa. kuwedzera, uye kupisa kwekupararira kunowedzera nekukurumidza. Nekuda kweizvozvo, kupisa kwekupisa kuburitswa kunowedzera, kudzvanya kudzvanywa uye tembiricha yecylinder inowedzerwa, uye NO kugadzirwa kunowedzerwa zvinoenderana15. Mufananidzo 9 unoratidza chikamu chedhiziri chakatorwa kubva pamuchinjikwa pahurefu hwakafanana neburi remuromo pa380°CA. Zvinogona kuwanikwa kuti sezvo nguva yejekiseni yakapfupikiswa, kupisa kunotanga kare uye kunowedzera zvakanyanya; kuwedzera, chikamu chedhiziri chakasara chinoderedzwa pa 380 ° CA uye chikamu chekupisa chinopera zvakare chakaderedzwa. Izvi zvinoitisa kuvandudzwa kwesimba rinoshanda.
