Cov nyhuv ntawm Ob Chav Injector ntawm Cov Txheej Txheem Kev Sib Txuas hauv 396 Series Diesel Cav (ib ntu 3)
Combustion qauv
Cov yam ntxwv tsis sib xws ntawm 396 series diesel cav nrog lub tiaj tiaj tiaj lub hauv paus combustion chamber muaj nyob rau hauv Table 1. Cov qauv geometric yog kos los ntawm ProE software, lub mesh faib ua tiav los ntawm Hypermesh software, thiab tom qab ntawd cov mesh yog optimized thiab encrypted los ntawm AVL FIRE. Lub dynamic mesh yog teem rau kev xam thiab kev soj ntsuam tom qab ua tiav. Raws li cov airflow txav nyob rau hauv lub tog raj kheej yog asymmetrical thiab nws muaj feem xyuam rau lub spatial faib ntawm cov roj tsuag thiab ces nyob rau hauv combustion txheej txheem, tus qauv yog tsim rau tag nrho cov combustion chamber. Muaj 56050 thiab 158900 mesh hlwb ntawm TDC (qhov chaw tuag saum toj kawg nkaus) thiab BDC (hauv qab qhov chaw tuag) feem, thiab cov qauv combustion chamber ntawm TDC tau qhia hauv daim duab 1.9.
Cov tsis tseem ceeb ntawm 5-qhov thiab 8-qhov injectors thiab 4-qhov dual-injector yog qhia nyob rau hauv Table 2, thiab injectors nrog txawv qhov txhaj tshuaj muaj tib yam tag nrho cov zoo ntws hla seem cheeb tsam. Kev faib tawm ntawm cov tshuaj tsuag hauv lub tog raj kheej tom qab cov roj txhaj tshuaj ntawm 5 ° CA yog qhia hauv daim duab 2. Qhov sib piv tam sim no hauv lub tog raj kheej yog teem rau 2.9, lub zog ntawm lub tog raj kheej yog asymmetric vim txoj hauj lwm ntawm lub inlet valve, thiab roj. tshuaj tsuag kuj cuam tshuam los ntawm airflow txav raws li.10.
Cov tshuaj lom neeg cov tshuaj tiv thaiv dynamic suav suav nrog cov qauv kev thauj mus los ntawm cov khoom siv hluav taws xob ntawm FIRE, thiab cov qauv kev xaiv lub ntsiab lus suav tau pom nyob rau hauv Table 3. Hauv KHRT spray breakup qauv, tus nqi ntawm coefficient C2 yog teem rau 12.
3. Simulation cov txiaj ntsig thiab kev tsom xam Daim duab 3, Daim duab 4 thiab daim duab 5 raws li qhia kev sib piv thiab kev tsom xam ntawm lub siab nyob rau hauv lub tog raj kheej, qhov kub tso tawm tus nqi, qhov nruab nrab kub hauv lub tog raj kheej, cov cua kub tso tawm thiab tsis muaj qhov loj me thaum 5-qhov thiab 8-qhov injectors thiab 4-qhov dual-injector raug saws.
