Diesel Injector Fuel Injector 095000-5670 23670-30090 23670-39125 Denso Injector yeToyota

In-cylinder yakananga jekiseni tekinoroji yakasiyana zvakanyanya neiyo port jekiseni tekinoroji. Kune yakananga-jekiseni peturu injini, ingave inotora yakaonda kupisa pasi peyakaderera-mutoro mamiriro, inotora stratified combustion pasi pepakati-mutoro mamiriro, kana kutora nzira yekupisa yeyakaenzana reshiyo musanganiswa pasi peyakanyanya-mutoro mamiriro, iyo yakananga-jekiseni peturu jekiseni Hunhu. yeatomization inoita basa rakakosha mukuumbwa kwemusanganiswa mucylinder.
Zvinoenderana nemaitiro ekutyaira, iwo majekiseni eakananga jekiseni peturu injini anogona kukamurwa kuita emagetsi majekiseni uye piezoelectric crystal majekiseni. Iyo electromagnetic mafuta jekiseni inonyanya kudzora kuvhurwa nekugara kwevharuvhu yetsono nekupa simba coil, uye piezoelectric crystal mafuta injector inonyanya kushandisa inverse piezoelectric effect kudzora kusimudza kweshaft tsono, kuitira kuti uone kuvhurwa nekuvhara kweiyo. jekiseni remafuta. . Mabhenefiti makuru epiezoelectric crystal yakananga jekiseni peturu majekiseni ipfupi yakanyanyisa mafuta jekiseni mhinduro nguva, chaiyo mafuta metering uye yakanaka kudzokorora. Iyo Siemens injector inogona kusvika pakakwirira pintle kusimudza mukati me20us, uye nguva yekuvhara inenge 200us. Kusimudzwa kwepintle kunogona kudzorwa nekudzora kurodha voltage yepiezoelectric crystal, kuitira kuti huwandu hwejekiseni remafuta hugone kugadziridzwa zviri nyore pasi peiyo yepamusoro jekiseni yekumanikidza mamiriro.
Yakananga jekiseni peturu majekiseni anogona kukamurwa kuita swirl mhando, akawanda-gomba mhando uye yekunze yekuvhura mhando zvinoenderana neyakapfava chimiro. Kune majekiseni emhando ye swirl, kana mafuta akanyanya-kudzvanywa achiyerera kuburikidza nejenareta yevortex mukati meinjector, A hollow cone yespray inoumbwa pane injector yekubuda. Mafuta akapfapfaidzwa ari pasi pechiito che centrifugal simba uye anodhumhana nemhepo yakatenderedza, saka iyo mafuta atomization mhando iri nani. Nekudaro, iyo hollow conical chimiro chakaumbwa pakubuda kwenozzle chinokanganiswa zvakanyanya nekudzvanywa kwejekiseni uye ambient back pressure, kunyanya kana yekumashure kudzvinyirirwa kwakakwira. Naizvozvo, kana oiri ichinge yaiswa jekiseni panguva yekudya sitiroko, nekuda kweiyo diki yekumashure yekumanikidza, iyo yakaumbwa yekupfapfaidza chimiro inopa isina mhango uye inopararira conical chimiro, icho chinobatsira maitiro ekusanganiswa kweoiri-gasi. Zvirinani atomization mhando inowanikwa kunyangwe kune yakaderera jekiseni kumanikidza. Zvisinei, kana mafuta akaiswa panguva yekumanikidzika, nekuda kwepamusoro ambient back pressure, chimiro chepfapfaidzo chinodzikira, izvo zvisingakodzeri kuumbwa kwegasi rakasanganiswa mucylinder.
