Denso fuel injector

(1) Ramba uchishandisa nekuvandudza iyo yekudzora orifice chimiro kuti uwedzere kudzikisa nguva yejekiseni remafuta. Inofananidzwa neG4S, G4.5S inovandudza mararamiro emvura anononoka evhavhavha yenzira mbiri apo iyo inofambisa yekudzora orifice yakavhurwa, kuitira kuti kumanikidzwa muimba yekutonga kunosvika uye kuchengetedza chikamu chepasi, kuitira kuti valve yetsono inotevera inogona kukurumidza. yakavharwa. open. Zvinofungidzirwa kuti jekiseni remafuta eG4.5S rinogona kusvika 0.1ms mune ramangwana, uye chizvarwa chechina piezoelectric jekiseni G4P inogona kuona hapana nguva yejekiseni remafuta.
(2) Deredza dhayamita yegomba rejojo ​​jekiseni uye uvandudze chimiro chegomba remhuno, nokudaro uchivandudza diffusible yepfapfaidzo. Kuti uwane kupararira kwakanyanya uye kuderera kwekupinda nekudzika njanji, uye panguva imwe chete kuti uwane kupindira kwakasimba kwakafanana nekumanikidza kwenjanji seyakajairwa majekiseni emafuta, Denso Corporation yakagadzira muromo une chiyero che 0.1x0.8 mm. Short orifice kana yakakosha-yakaita mhuno (CDS, Inodzorwa Diffussive Spray Nozzle) kuti uwane yaunoda kupfapfaidza mhedzisiro.
(3) Kuvandudza i-art basa kuti uone kutariswa kwe pre-jekiseni uye mainjekiseni majekiseni. Panguva imwecheteyo, shanduko yekumhanya kwenzwi inogona kuwanikwa nekuyera chikamu cheiyo pressure wave mushure mekunge jekiseni rapera, kuitira kuti uwane huwandu hwemafuta. Ipapo kinematic viscosity inowanikwa kuburikidza nehukama hunozivikanwa pakati pen-cetane nhamba yemafuta uye hukama pakati pehutsi uye dynamic viscosity, kuitira kuti uone kururamisa kwekuyerera kwehuwandu hwemafuta akaiswa jekiseni, nezvimwewo.
