Made in China Fuel Injector 0445115062 Diesel Fuel Injector 0 445 115 062 for Bosch

Ts'ebetso ea enjene ea diesel e fetolang matla a mocheso hore e be matla a mochini e finyelloa ka lits'ebetso tse 'ne tse tsoelang pele: ho kenya, ho hatella, ho sebetsa le ho tsoa. Mokhoa o mong le o mong o joalo o bitsoa potoloho ea ho sebetsa. Enjene leha e le efe e phethang potoloho ea ho sebetsa ka ho potoloha crankshaft ka makhetlo a mabeli le ho khutlisa piston ka makhetlo a mane e bitsoa enjene ea methapo e mene. Molao-motheo oa ts'ebetso oa enjene ea dizeli e nang le methapo e mene:

1. Ho ja setorouku

Crankshaft e khanna piston ho tloha setsing se shoeleng se ka holimo ho ea setsing se tlase se shoeleng. Ka nako ena, valve ea ho kenya e bulehile 'me valve ea ho qeta e koetsoe. Nakong ea ho sisinyeha ha piston, molumo oa cylinder o eketseha butle-butle, o etsa vacuum, kahoo motsoako o tukang o kenngoa ka har'a silinda ka valve ea ho noa ho fihlela piston e fihla setsing se shoeleng se ka tlaase 'me valve ea ho kenya e koetsoe.

Ka lebaka la ho hanyetsa ho kenngoa ha tsamaiso ea ho noa, khatello ea khase e ka har'a silinda qetellong ea ho kenngoa e tlaase ho feta khatello ea sepakapaka, e ka bang 0.075MPa ~ 0.09MPa. Ka lebaka la ho futhumala ha likarolo tse phahameng tsa mocheso tse kang lerako la silinda le piston le khase ea ho qeta mocheso e phahameng e setseng nakong e fetileng, mocheso oa khase o nyolohela ho 370K ~ 440K. Se kenang ka cylinder nakong ea ho ja lijo hase motsoako o tukang, empa ke moea o hloekileng.

2. Compression stroke

Qetellong ea leqeba la ho noa, piston e tloha setsing se shoeleng se ka tlaase ho ea setsing se ka holimo se shoeleng se tsamaisoang ke crankshaft, 'me molumo oa cylinder o fokotseha butle-butle. Ka nako ena, li-valve tsa ho kenya le ho qeta li koetsoe, 'me moea o hloekileng o hatelloa. Khatello e fela ha piston e fihla setsing sa bafu se holimo. Nakong ea ts'ebetso ea khatello, khatello ea khase le mocheso li eketseha ka nako e le 'ngoe,' me motsoako o tsoela pele ho tsoakana. Kaha tekanyo ea khatello ea disele e kholo, e ka bang 15 ho isa ho 22, mocheso le khatello qetellong ea khatello e batla e phahame, khatello e ka fihla 3MPa ho 5MPa, 'me mocheso o ka fihla ho 800K ho 1000K.

3. Matla a matla

Qetellong ea setorouku sa khatello, pompo ea ente ea mafura e fafatsa diesel e nang le khatello e phahameng moeeng o phahameng oa mocheso le moea o phahameng ka har'a silinda ka ente ka mokhoa oa moholi, o phophomang kapele ebe o etsa motsoako le moea. Kaha mocheso oa silindara o phahame ho feta mocheso oa auto-ignition oa diesel (hoo e ka bang 500K), motsoako oa diesel hang-hang oa hotetsa le ho chesa ka boeona, 'me ka nako e itseng ka mor'a moo, khatello le mocheso oa silinda li phahama haholo ha li ntse li enta. mafura, ho sututsa piston tlase ho etsa mosebetsi. Nakong ea matla a matla, khatello ea hang-hang e ka fihla ho 5MPa ~ 10MPa, 'me mocheso oa hang-hang o ka fihla 1800K ~ 2200K.

4. Exhaust stroke

Ha matla a matla a haufi le ho fela, valve ea ho qeta e bula, valve ea ho kenya e koala, 'me crankshaft e sutumetsa piston ho tloha setsing se shoeleng se ka tlaase ho ea setsing se shoeleng se ka holimo ka molamu o kopanyang. Khase ea ho ntša metsi e ntšoa ka har'a silinda tlas'a khatello ea eona e setseng le ho sututsa piston. Ha piston e fihla setsing se ka holimo se shoeleng, valve ea ho tima e koala 'me mokelikeli o fela. Hobane ho na le khanyetso ea ho qeta tsamaiso ea ho qeta nako, qetellong ea leqeba la ho qeta, khatello e ka har'a silinda e phahame hanyenyane ho feta khatello ea sepakapaka, e ka bang 0.105MPa ~ 0.115MPa, 'me mocheso o ka bang 900K ~ 1200K.

Har'a lichapo tse 'nè, ke stroke ea matla feela e hlahisang matla,' me lichapo tse ling tse tharo ke liropo tse thusang ho itokisetsa matla a matla, 'me kaofela li ja matla a itseng. Potolohong ea pele ha enjene e qala, ho tlameha ho be le matla a kantle ho potoloha crankshaft ho phethela liropo tsa ho kenya le ho hatella. Ha matla a matla a qala, matla a sebetsang a bolokoa ka flywheel ka crankshaft ho boloka tsoelo-pele ea lipotoloho tse latelang.
