Tshiab Diesel Roj Injector A6510700487 28246359 rau Mercedes E-Class W211 W203 W204 Cl203 W639 C209 220 Gdi / Cdi 220/250 Cdi Diesel

Tsim thiab tshuaj xyuas ntawm ntau cov roj injector(part 4)

Gas injector optimized tus nqi txhaj tshuaj, injector momentum, injector internal geometry, thiab injector nozzle.Cov kws tshawb fawb tau ua qauv rau cov tshuaj txhaj tshuaj siv Bond graph qauv txheej txheem.Lawv kuj tau ua cov kev tshawb fawb simulation rau kev kawm txog tus cwj pwm dynamic.Deyang [8] tau ua nws qhov kev tsim kho raws li patent WO 2013/188247, uas nws cov txiaj ntsig yog kev siv ib leeg thiab ntau cov roj txhaj tshuaj nrog kev siv zog thiab qhov sib txawv ntawm cov roj av thiab diesel.

Cov kev tshawb fawb leveraged cov khoom siv roj sib txawv thiab cov qauv tshuaj tsuag sib txawv.Cov khoom tsim tau txuas ntxiv mus rau kev txheeb xyuas cov roj viscosity tsawg, suav nrog ethanol, LNG, thiab cov roj viscosity siab, suav nrog biodiesel, Jet Propellant -8 (JP-8) roj.Cov ntaub ntawv tshuaj xyuas tau qhia qhov tsis muaj kev tshawb nrhiav hauv kev simulation. ntawm cov roj injectors.Yog li ntawd, kev tshawb fawb kom meej yuav tsum tau ua nyob rau hauv kev tsim ntawm ib tug multi-fuel universal gas injector rau combustion khoom, xws li IC engines, gas burners, furnaces, thiab gas turbines, uas muaj peev xwm txhaj ntau yam kua thiab gaseous fuels raws li lub muaj nyob hauv zos.

Lub hom phiaj tseem ceeb ntawm cov kev tshawb fawb tam sim no yog tsim, qauv, thiab simulate ib tug ntau-fuel injector uas muaj peev xwm ua hauj lwm siv ntau yam fuels adaptable rau txawv combustion khoom.Lub injector yuav tsum muaj peev xwm tsim tau lub zog uas yuav tsum tau muaj, txaus torque, thiab kev siv roj tsawg.Lawv kuj yuav tsum muaj peev xwm txhaj tshuaj kom muaj nuj nqis ntawm cov roj ntawm lub sijhawm tshwj xeeb, tshwj xeeb tshaj yog thaum lub sij hawm nqus los yog thaum lub sij hawm compression stroke.Kev txhaj tshuaj kuj yog nyob ntawm qhov chaw ntawm lub injector ntawm lub manifold lossis ntawm lub cav lub taub hau rau kev txhaj tshuaj ncaj qha.

Roj injector yog ib qho cuab yeej siv los txhaj lossis txau cov roj rau hauv cov khoom siv hluav taws xob sib xyaw rau kev npaj cov stoichiometric cua-roj sib tov, yog li muab kev sib xyaw kom zoo.Cov roj injector yog lub plawv ntawm cov roj txhaj tshuaj.Raws li kev nce qib ntawm cov thev naus laus zis, ntau yam kev txhaj tshuaj roj muaj nyob rau raws li daim ntawv thov yuav tsum muaj xws li, lub cev txhaj tshuaj, MPF (Multi-point fuel), txhaj tshuaj Manifold, Chaw nres nkoj txhaj tshuaj, thiab txhaj tshuaj ncaj qha.
