Mashandiro anoita jekiseni

"High pressure common rail" sezvinoreva zita, i "common rail" uye "high pressure". Iko kune yakajairika high pressure, uye haina chekuita nekumhanya kweinjini. Kudzvinyirirwa mujekiseni remafuta ejini yedhiziri yepamusoro-yakajairika inogona kusvika 20,000kpa. Kutsikirirwa kweoiri ndiyo nhanho yekubudirira kweiyi system. Pasi pekudzvanywa kwemafuta akadai, iyo yese system inogona kupedzisa iyo chaiyo mafuta ekupa nenzira dzakasiyana dzejekiseni uye mavhoriyamu emafuta ejekiseni pasi pemirairo yemagetsi ekudzora module.
Kana iyo yakakwira-kudzvanywa mafuta inounzwa kune injector yemafuta kuburikidza neyakajairika njanji, inogona pakupedzisira kupinza dhiziri mucylinder ine chiyero chakanyanya uye panguva chaiyo pasi pekutonga kweiyo yepamusoro yemagetsi controller. Naizvozvo, kusiyana neyakajairwa injini yedhiziri inongobaya mafuta kamwe chete panguva yese yekutenderera, injini yedhiziri pasi peiyo high-pressure common rail tekinoroji inogona kuwana kakapetwa kasere kubva pakutanga kusvika kumagumo. Iyi nzira inotanga nehuwandu hushoma hwepre-jekiseni pakutanga, zvishoma nezvishoma inowedzera huwandu hwemafuta anobaiwa uye inomhanyisa kumhanya kwejekiseni sezvo piston inodzvanya zvishoma nezvishoma musanganiswa mucylinder kusvika pachiyero chidiki, kusvika jekiseni guru ravepo. , uye inopedzwa Iyo yose yekupfapfaidza nzira isati yashanda sitiroko. Ese emafuta edhiziri aya atomisikidzwa uye akapfapfaidzwa pamapoinzi akawanda nemajekiseni emafuta. Kuzvibatanidza mumutsara mumwechete, zvinokanganisa maitiro ekutanga majekiseni emafuta, asi anosvika pakupisa kwemafuta zvakanyanya uye anosvina simba riri mudonhwe rega rega remafuta. Nekune rimwe divi, kukwirisa kwakanyanya kunoreva mazinga akakwira ekuburitsa. Uye iyi yakajairika njanji system inogona zvakare kuburitsa ruzha rushoma pane yechinyakare injini dzedhiziri. Nekuti iyo mafuta ekupa nzira yeakawanda-point jekiseni inoderedza kwainobva kwakawanda vibrations. Uyezve, kudengenyeka kwakaputika kamwe chete panguva yekushanda kwekushanda kwakaputsikawo ne micro-vibration yezvizhinji-nhanho-nhanho inopisa.
