Umgangatho ophezulu weDizili yokutofa uMbhobho DLLA155SM067 105025-0670 iNdawo eSpareleyo yoMlomo weFuel

Impembelelo ye-pre-injection kwinkqubo yokutshisa i-injection ephambili ifundwe kwiincwadi.Iziphumo zibonisa ukuba imveliso yokutsha ye-injection yangaphambili inempembelelo yokuthintela ekutshisweni kwesitofu esiphambili.Xa i-Angle yangaphambili ye-injection yangaphambili inkulu, inani elifanelekileyo le-pre-injection linokuphucula ukukhutshwa kwe-NOx.Impembelelo ye-post-injection yaxutyushwa kwiincwadi, kwaye kwafunyaniswa ukuba ukunyusa umthamo we-post-injection kunye nekhefu kunokunciphisa ukuveliswa kwe-NOx, kodwa uqoqosho lwamafutha lwaba lubi.Iimpembelelo zoxinzelelo lwenaliti kunye nexesha lokutofa ekusetyenzisweni kwamafutha kunye nokukhutshwa phantsi kwe-EGR atmosphere ziye zafundwa kuncwadi.Iziphumo zibonisa ukuba uxinzelelo lwenaliti olufanelekileyo kunye nexesha lokutofa linokwandisa ukusetyenziswa kwamafutha.Kwelinye icala, ngenxa yokuba i-cylinder diameter ye-speed ephantsi-speed two-stroke Injini yaseLwandle ifikelela kumakhulu eemilimitha, ukuze kusetyenziswe ngokupheleleyo umoya kwigumbi lokutsha, ii-injector zamafutha ezimbini okanye ngaphezulu zicwangciswa ngokubanzi ngaphandle kwe-cylinder. , kunye nokulungiswa kwee-injection zamafutha kuya kuba nefuthe elibonakalayo kwinkqubo yokutshisa.Uphononongo kwi-injection Angle ye-injini ye-diesel ene-stroke ephindwe kabini luye lwenziwa kwiincwadi, kwaye kufunyenwe ukuba ukulungelelanisa ulwalathiso lwenaliti kunokunciphisa imveliso ye-NOx ngama-20%.Impembelelo yolwalathiso lwe-nozzle ekutsha kunye nokukhutshwa kwafundwa kuncwadi.Iziphumo zabonisa ukuba icala le-nozzle lalisondele kakhulu, kwaye iindawo ezityebileyo ze-oyile kwi-cylinder zenziwe, nto leyo eyandisa ukukhutshwa kwe-soot.Isalathiso sombhobho esahlukileyo kakhulu siyakonyusa umxube obhityileyo, sinciphise ukusetyenziswa kwamafutha kodwa sinyuse ukukhutshwa kwe-NOx.
