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-pre-injection 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 olufanelekileyo lwesitofu 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 nokucwangciswa kwee-injection zamafutha kuya kuba nefuthe elibalulekileyo 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 umkhombandlela womlomo wawusondele kakhulu, kwaye iindawo ezityebileyo zeoyile kwi-cylinder zenziwa, nto leyo eyandisa ukukhutshwa kwesoot. Isalathiso sombhobho esahlukileyo kakhulu siyakonyusa umxube obhityileyo, sinciphise ukusetyenziswa kwamafutha kodwa sinyuse ukukhutshwa kwe-NOx.
