Kunyange zvazvo injini yedhiziri ingava nezvinhu zvakawanda, chikamu chiduku chimwe chete chinoita kuti injini irambe ichirira. Chikamu chidiki ichi ijekiseni remafuta, inova chikamu chakakosha chemotokari yemajekiseni emafuta.
Makambani akati wandei akashandisa madhora epamusoro muR&D kukwirisa chikamu chidiki ichi sezvo chine chekuita nekuita kwemotokari dzedhiziri.
Mungava mumotokari, marori, -mumotokari dzinobuda mumigwagwa, kana{1}}zvinorema, majekiseni anoita basa guru pakutsanangura kushanda kweinjini maererano nekushanda zvakanaka kwemafuta, kuburitsa, uye kurarama kwenguva refu.
Muchinyorwa chino, tichaongorora majekiseni nemasisitimu edhiziri, tichitanga nekuziva-mashandiro anoita injini dzedhiziri uye basa rinoitwa nemajekiseni pakupisa.
Diesel Injini Dzinoshanda Sei?
Dzese peturu nedhiziri mota dzemafuta dzinoshanda patekinoroji yekupisa kwemukati. Dzinosiyana nenzira iyo mafuta anopinzwa nayo mukamuri rinopisa nokuda kwekupisa.
Muinjini dzepeturu, mhepo-musanganiswa wemafuta unobatidzwa mukati mekamuri rinopfuta nespark inobva paspark plug.
Sezvo pasina spark plugs muinjini dzedhiziri, kupisa kunoitika kana mafuta akaunzwa zvakananga mukamuri panguva yekumanikidza sitiroko. Pakumanikidzana, kudzvanya uye tembiricha yemhepo mukati mekamuri inokwira zvakanyanya zvichiita kuti mhepo ibatidzwe-chaji yemafuta.
Basa reDiesel Majekiseni
Basa re dhiziri jekiseni ndere kupa chaiwo uye metered huwandu hwehuturu hweatomu panguva chaiyo. Zvinogona kuita sezviri nyore, asi kune yakawanda tekinoroji inopinda mune izvi.
Izvo zvakakosha zvakabudirira zvakawanikwa mukufambira mberi kweinjini yedhiziri zvinogona kukonzerwa zvakananga nekufambira mberi kwehunyanzvi hwejekiseni.
Injector inofanirwa kuve nechokwadi chekutakura mafuta kunyangwe kudzvanywa uye tembiricha mukati mekamuri. Injector pressure inogona kusvika ku36,000 PSIG (atmospheric pressure inenge 1 PSIG), uye tembiricha inogona kusvika 1000 degrees Fahrenheit.
Nekuda kwekufambira mberi kwetekinoroji yejekiseni, mutengo wayo unogona kumiririra kusvika 30% yemutengo wakazara weinjini.
Magadzirirwo uye mainjiniya emajekiseni anokanganisa zvakanyanya kushanda kweinjini pachayo.
Kushanda kwemafuta, hunhu hweruzha, uye mazinga ekuburitsa zvinokanganiswa netekinoroji injector tekinoroji uye dhizaini.
Decoding iyo Diesel Fuel Injection System:
Kuti uzive kuti mhando dzakasiyana dzemajekiseni edhiziri dzinoshanda sei, zvakakosha kuti unzwisise iyo jekiseni yemafuta. Chimwe nechimwe chikamu muhurongwa pamwe chete nemajekiseni chinoita basa rakasiyana mukuona kuti mafuta anobaiwa nemazvo. Hezvino zvikamu zveinjini yedhiziri:
1. Nozzle:
Pamwoyo wejekiseni rega rega pane muromo. Mumuromo chikamu chidiki chejekiseni chinopinza mafuta mumhute yakanaka yemadonhwe madiki isati yapinzwa mukamuri rinopisa. Atomizing mafuta kwakakosha pakupisa nekukurumidza.
Mupumburu wakanyatsogadzirwa-unjiniya kuti uone kuti patani yekupfapfaidza mafuta inoenderana nekupisa nekupisa.
2. Varuvhu yetsono
Ivhavhavha yetsono, inozivikanwawo sevhavha yekudzora, inoshanda pamwe chete nemuromo. Varuvhu yetsono inodzora kuyerera kwemafuta nekuvhura nekuvhara muromo wejekiseni. Uyu murairo wakakosha kune chaiyo nguva uye metering, ichibvumira injini kuti ishande nemazvo mumamiriro akasiyana ekushanda.
3. Solenoid
A solenoid is electromagnetic coil mukati meinjector inoshanda sevhavha. Iyo solenoid inopindura zviratidzo zvemagetsi kubva kuElectronic control unit (ECU), zvichibva pane iyo inovhura kana kuvhara jekiseni.
Funga nezveECU sechipi chakarongwa chinopa mirayiridzo kune zvikamu zvakakosha zvemotokari, kusanganisira majekiseni nemajekiseni emafuta.
Solenoid inogonesa jekiseni kuti riunze huwandu chaihwo hwemafuta panguva yakakodzera, zvichibatsira maitiro ekupisa.
4. Yepamusoro-Pumpu Yekudzvanya
Sezvinoratidzwa nezita racho, basa repombi-yakakwirira nderekugadzira simba guru uye kudzvanya mafuta kuitira kuti ikwanise kukunda kukwira mukati mekamuri uye kuramba ichibaya mafuta eatomu. Kune mechanic pombi masisitimu uye yakajairika njanji dhiziri masisitimu, imwe neimwe iine mabhenefiti ayo akasiyana.
5. Mitsetse Yemafuta & Mafirita Emafuta
Mitsetse yemafuta inetiweki yakaoma kunzwisisa yepombi nemachubhu anotakura mafuta kubva mutangi kuenda kune jekiseni. Chero kukanganisa kana kukuvadzwa kwemitsara yemafuta kunogona kutungamirira mukudonha kwekumanikidzwa kunokanganisa kushanda kwemajekiseni.
Mafirita emafuta anobvisa zvinosvibisa kubva mumafuta sezvo zvinosvibisa zvichigona kukonzeresa kukuvadzwa kwezvimiro zvakaita semajekiseni. Kazhinji, kusefa kunoitika mumatanho akati wandei, kutanga kubva mutangi kana pombi yekufambisa, ichiteverwa nedanho rekutanga uye rechipiri rekusefa.
Mhando dzeDiesel Injector:
Kune akati wandei emafuta jekiseni emhando, imwe neimwe iine zvayakasiyana zvayakanakira uye zvinogumira. Mamwe marudzi ejekiseni emafuta akanyorwa pazasi:
Unit Majekiseni: Izvi zvinobatanidza pombi uye nozzle kuita imwechete unit, inopa kugona kwenzvimbo. Nekudaro, ivo vanounza matambudziko mukugadzirisa uye kugadzirisa nekuda kwekuoma kwavo.
Common Rail Injector: Ichishanda ine-pressure fuel rail, majekiseni aya anoita kuti mafuta anyatsouya panguva chaiyo mumajekiseni akawanda.
Hydraulically Actuated Majekiseni: Kushandisa hydraulic pressure kushandisa nozzle, majekiseni aya anodhura-anoshanda uye ari nyore pane akasiyana emagetsi asi anogona kukanganisa kunyatsojeka.
Piezoelectric Majekiseni: Kubatanidza piezoelectric makristasi ekudzora nozzle, ivo vanova nechokwadi chehunyoro kuendesa mafuta uye nguva, kunyangwe nemutengo wakakwira.
Kuchengetedza majekiseni emafuta:
Sezvinoita chero chinhu chemotokari, kugara uye kwakarongwa kugadziridzwa kwemajekiseni masisitimu uye majekiseni kwakakosha kuti uwane kunyatsoita kwemafuta, inodiwa ruzha hunhu, uye emission control. Heano maitiro aunokwanisa kuchengetedza majekiseni masisitimu:
Shandisa-mafuta emhando yepamusoro: Ita shuwa kuti mafuta edhiziri ako haana zvinosvibisa kunyangwe ungave nemasefa sechikamu chejekiseni remafuta.
Chinja mafirita emafuta: Mafirita emafuta anouya nehupenyu hushoma hunotsanangurwa nemugadziri. Ita shuwa kuti mafirita achinjwa sekurudziro yeOEM. Mafirita akavharika anokanganisa kuyerera kwemafuta uye anogona kukuvadza majekiseni anodhura.
Shandisa jekiseni jekiseni: Periodic kucheneswa kwejekiseni uchishandisa yakakurudzirwa yekuchenesa inova nechokwadi chekubviswa kwekuvhara uye tsvina kubva kune jekiseni.
Ita kuti majekiseni ako atariswe uye ashandiswe nehunyanzvi: Kugara uchiongorora uye sevhisi nenyanzvi makanika kunogona kubatsira kuona matambudziko zvisati zvaitika
Kukwirisa Diesel Injini Yekuita neiyo Right Injector:
Kubata manuances emhando dzakasiyana dzemajekiseni emafuta edhiziri uye masisitimu ejekiseni kunopa varidzi vemotokari simba rekukoshesa basa ravo rakakosha mukuchengetedza kushanda kwakasimba kweinjini dzedhiziri.
