Diesel Injector Fuel Injector 0445110362 0445110363 Bosch for VW / Audi / Isihlalo / Skoda 2.0 Tdi Cr

Ngokunyuka kokusetyenziswa kwepetroli kunye nemithetho engqongqo yokukhutshwa kombhobho e-China, injini yepetroli yesiko yesiko ayinakukwazi ukuhambelana neemfuno zamaxesha. Iinzuzo ziye zaxatyiswa ngakumbi ngabavelisi abakhulu beemoto. Iimpawu zokutshiza ze-injector ye-GDI ye-injini yepetroli zichaphazela ngokuthe ngqo amandla, uqoqosho kunye nokukhutshwa kwe-injini [! Uphononongo lweempawu zokutshiza phantsi koxinzelelo oluphezulu lwenaliti kweli phepha lubonelela ngesiseko sethiyori kuphando lwe-injini yepetroli ye-GDI. Uphando oluninzi luye lwenziwa kwizinto ezichaphazela iimpawu zokutshiza ze-GDI ekhaya nakwamanye amazwe: Yena Bangquan et al. baye bafunda iimpawu zokutshiza ezikufutshane nentsimi ngaphakathi kwe-1.5 mm ngaphantsi komngxuma womlomo we-injector yepetroli enomngxuma omnye ngokuthe ngqo ngokudibanisa imakroskopu yomgama omde kunye nokufota ngesantya esiphezulu. [2, Uxinzelelo lwe-injector esetyenziswe kuphando luphantsi. ULi Yanfei et al. wafunda iziphumo zoxinzelelo lwenaliti, uxinzelelo lwangasemva kunye nobubanzi be-pulse yesitofu kwiimpawu zokutshiza ze-petroli ye-injector ngqo ye-injini (GDI) injini ye-porous injector ngokusebenzisa i-high-speed photography kunye nesigaba se-Doppler iteknoloji yokulinganisa i-particle (PDPA). Kubandakanya umgama wokungena wokutshiza, ubungakanani bamasuntswana kunye neempawu zesantya [3]. Nangona eli nqaku libandakanya umgama wokugqobhoza kokutshiza, ikakhulu lifunda impembelelo yoxinzelelo lwenaliti kumgama wokugqobhoza kokutshiza, kwaye alifundisi ngempembelelo kwi-engile yokutshiza. UCheng Qiang et al. wafunda isiphumo sokwakheka komngxuma wombhobho kwiimpawu zokutshiza ze-GDI ii-injection [4. Jiang Long et al. wasebenzisa indlela ye-Schlieren ukufundisisa iimpawu zokutshiza ze-injection ye-injection ngokuthe ngqo phantsi koxinzelelo oluhlukeneyo lokusingqongileyo kunye nemithetho yesitofu kuxinzelelo lwe-injection ye-16 MPa [S]. U-Li Xiuhai wafunda ifuthe lobushushu be-oyile ye-oyile kwiimpawu zokutshiza [6], kwaye izinto eziphembelela uphononongo zazingatshatanga.
